AB  - Studying the membrane physiology of filamentous fungi is key to understanding their interactions with the environment and crucial for developing new therapeutic strategies for disease-causing pathogens. However, their plasma membrane has been inaccessible for a micron-sized patch-clamp pipette for pA current recordings due to the rigid chitinous cell wall. Here, we report the first femtosecond IR laser nanosurgery of the cell wall of the filamentous fungi, which enabled patch-clamp measurements on protoplasts released from hyphae. A reproducible and highly precise (diffraction-limited, submicron resolution) method for obtaining viable released protoplasts was developed. Protoplast release from the nanosurgery-generated incisions in the cell wall was achieved from different regions of the hyphae. The plasma membrane of the obtained protoplasts formed tight and high-resistance (GΩ) contacts with the recording pipette. The entire nanosurgical procedure followed by the patch-clamp technique could be completed in less than 1 hour. Compared to previous studies using heterologously expressed channels, this technique provides the opportunity to identify new ionic currents and to study the properties of the ion channels in the protoplasts of filamentous fungi in their native environment.

AB  - In this paper, the variability of morphological (stem height, stem basal diameter, proportion of pith, wood and bark) and wood anatomical characteristics (fiber length, fiber diameter, fiber lumen diamater, double cell-wall thickness, vessel diameter, wood rays width and height) of three Salix alba clones (B-44, 347 and NS 73/6) and one Salix viminalis clone both in the control plot and in the site contaminated with a mixture of heavy metals (As, Cd, Cr, Cu, Ni, Pb) was investigated. The observed results showed that individuals of all four clones had significantly higher average values of stem height and stem basal diameter at the control plot compared to the polluted site. As for the proportion of pith, bark and wood, heavy metals caused an increase in the share of pith and a decrease in the share of bark and wood in all clones with the exception of clone NS 73/6. The analysis of wood fiber dimensions showed that the values of all parameters were higher at the control site with the exception of fiber lumen diameter where higher values were observed for clones B-44 and NS 73/6 at the polluted site. Higher values of vessel diameter were recorded for all clones at the control plot, while wood rays width of all individuals was greater at the contaminated site. Regarding the wood rays height, only Salix viminalis showed higher value at the polluted site. These results confirmed that pollution-induced heavy metal stress significantly altered the morphological and wood anatomical characteristics of all researched clones and that it may affect their utility properties.

AB  - In order to further improve the performance of 0.94[(Bi0.5Na0.5)TiO3]-0.06BaTiO3/
polyvinylidene fluoride (NBT-BT/PVDF) flexible composite films prepared by the
hot-pressing method, the effect of surface modification of the NBT-BT particles on
the structure and properties of the films was investigated. Two coupling agents,
namely, (3-aminopropyl)triethoxysilane (APTES) and dodecyl triethoxysilane
(DDTES) were added to enhance dispersion and interfacial adhesion of the active
phase powder with the polymer matrix. The highest amount of the electroactive
PVDF β-phase was formed in APTES-modified samples while in DDTES samples
mainly γ-phase was formed as shown by Fourier-transform infrared spectroscopy
analysis. Differential scanning calorimetry measurements indicated that the addition
of filler particles reduced the total crystallinity degree of the PVDF. Dielectric
permittivity values as well as dielectric losses decreased for silanized samples due
to reduced tension at the interface between particles and polymer. Strong intermolecular
interaction between the PVDF chains and the APTES-modified particles
led to enhanced breakdown strength of these samples. The highest level of
agglomeration in the DDTES-modified samples induced the deterioration of ferroelectric
properties. The highest voltage output of  15 V and 225 μW of powerwas
obtained for the APTES-modified harvester, evidencing their potential for energy
harvesting applications.

AB  - In this paper, we have systematically studied the structural, morphological, and optical properties of Ni-doped TiO2, synthesized via a simple, cost-effective electrospinning method followed by calcination at 500 C. The nanofibers with a core-shell structure were relatively homogeneous, smooth and randomly oriented, and there were no significant differences in fiber diameters due to Ni2+ content. Core loss mapping using electron energy loss spectroscopy confirmed an even distribution of titanium and relatively uniform nickel in the fibers. It was found that doping with 0.5 mol.% Ni2+ decreased the rutile content, while doping with 1 mol.% Ni2+ resulted in a pure anatase phase with a significantly increased specific surface area (36.6 m2/g). Further increase in Ni2+ content (3-10 mol.%) not only prolonged the response of TiO2 nanofibers to visible light, but also increased the specific surface area (49.5 m2/g), decreased crystallite size (7 nm), and increased rutile content in TiO2 (33 wt.%). Photoluminescence analysis revealed that doping TiO2 with different amounts of Ni2+ leads to a gradual decrease of emission spectra intensity and red shift in the maxima positions. The XPS results confirmed that as the Ni2+ content enlarged, the Ti2+ and Ti3+ content increased significantly, effectively promoting the formation of oxygen vacancies. Raman analysis showed that an increase in nickel content (3-5 mol.%) led to a decrease and shift in peak intensity due to Ti3+ formation and also the possible presence of NiTiO3 phases. HRTEM analysis showed that Ni was doped into the substitution sites of both the anatase and rutile TiO2 lattice but had a stronger influence on the distortion of the anatase phase. The photocatalytic activity of Ni-doped TiO2 nanofibers was explored by analyzing the degradation of an antibiotic, oxytetracycline, monitored in laboratory conditions under visible light irradiation. After 60 minutes of irradiation, the degradation  of OTC with 1Ni-TiO2 reached 76.4% and with 10Ni-TiO2 70.5%.

AB  - Negative temperature coefficient (NTC) thermistor semiconducting oxides, such as ferrites used as resistance-based temperature sensors, remain in research focus, as they are basic building blocks of many electronic systems. In this work we have investigated NTC thermistor properties of a ferrite composite (MnFe2O4/Fe2O3) ceramics obtained by solid-state sintering in the form of a bulk sample with a diameter of 8.7 mm and thickness of 1.8 mm. We obtained a thermal (material) constant (B10,90) of 4390 K from measured impedance at 100 Hz in the temperature range 10 - 90 C and temperature sensitivity (alpha) of -4.87 %/K at 25 oC, that was within the range required for a commercial NTC thermistor material (B between 2000 and 5000,  between -2 and 6% K at room temperature -25 oC). The influence of relative humidity (RH) in the range 30-90% at 25 and 50 C on impedance in the frequency range 50 Hz – 1 MHz was monitored. The obtained results showed that at 100 Hz the change in impedance was from 8.15 to 3.56 Mohm at 25 oC and 2.81 to 1.65 Mohm for RH from 30 to 90%, indicating that the humidity influence was reduced compared to other NTC thermistor materials. Future work will focus on applying this ferrite composite in flexible printed temperature sensors.

AB  - Emission  of greenhouse gases and infectious diseases caused by improper agro-waste disposal has gained significant attention in recent years. To overcome these hurdles, agro-waste can be valorized into valuable bioactive compounds that act as reducing or stabilizing agents in the synthesis of nanomaterials. Herein, we report a simple circular approach using Citrus reticulata Blanco (C. reticulata) waste (peel powder/aqueous extract) as green reducing and capping/stabilizing agents and Zn nitrate/acetate precursors to synthesize ZnO nanoparticles (NPs) with efficient antimicrobial and photocatalytic activities. The obtained NPs crystallized in a hexagonal wurtzite structure and differed clearly in their morphology. UV-vis analysis of the nanoparticles showed a characteristic broad absorption band between 330 and 414 nm, belonging to ZnO NPs. Fourier transform infrared (FTIR) spectroscopy of ZnO NPs exhibited a Zn–O band close to 450 cm−1. The band gap values were in the range of 2.84-3.14 eV depending on the precursor and agent used. The crystallite size obtained from size-strain plots from measured XRD patterns was between 7 and 26 nm, with the strain between 16 and 4%.  The high crystalline nature of obtained ZnO NPs was confirmed by clear ring diffraction patterns and d-spacing values of the observed lattice fringes. ZnNPeelMan_400 and ZnNExtrMan have shown good stability as the Zeta potential was found to be around -20 mV and reduced particle aggregation. Photoluminescence analysis revealed different defects belonging to oxygen vacancies (VO+ and VO++) and zinc interstitial (Zni) sites. The presence of oxygen vacancies on the surface of ZnAcExtrMan_400 and ZnAcPeelMan_400 increased antimicrobial activity, specifically against gram-negative bacteria Escherichia coli (E.coli) and Salmonella enteritidis (S. enteritidis). ZnNextrMan with a minimal inhibitory concentration of 0.156 mg/ml was more effective against gram-positive bacteria, Staphylococcus aureus (S. aureus) revealing a high influence of particle size and shape on antimicrobial activity. In addition, the photocatalytic activity of the ZnO NPs was examined by assessing the degradation of acid green dye in an aqueous solution under UV light irradiation. ZnAcPeelMan_400 exhibited excellent photocatalytic activity (94%) within 90 minutes after irradiation compared to other obtained ZnO NPs.

AB  - In this work we have characterized and compared chitin sourced from exoskeleton of Tenebrio molitor larvae fed with polystyrene or plastic kitchen wrap combined with bran in the ratio 1:1 with chitin sourced from larvae exoskeleton fed only with bran. Analysis of the frass by ATR-FTIR showed very similar spectra and confirmed degradation of the plastic feed components, while ATR-FTIR analysis of the exoskeleton verified the absence of any plastic residue. Deproteinization followed by demineralization produced 6.78 -5.29 % chitin, showing that plastic (polystyrene or plastic kitchen wrap) in the larvae diet resulted in heavier insect exoskeleton, but yielded slightly less chitin, with the lowest value obtained for plastic kitchen wrap in the insect diet. The deacetylation degree of 98.17-98.61% was determined from measured ATR-FTIR spectra. XRD analysis confirmed the presence of -chitin with a crystallinity index of 66.5-62% and crystallite size 4-5 nm. Thermogravimetric analysis showed similar degradation curves for all chitin samples, with two degradation steps. These results show that chitin sourced from exoskeleton of T. molitor larvae fed with plastic (polystyrene or plastic kitchen wrap) and contributing to significant biodegradation of major polluting materials can be a feasible and alternative source of chitin, further promoting a bio-circular economy.

AB  - In this paper, we have systematically studied the structural, morphological, and optical properties of Ni-doped TiO2, synthesized via a simple, cost-effective electrospinning method followed by calcination at 500 C. The nanofibers with a core-shell structure were relatively homogeneous, smooth and randomly oriented, and there were no significant differences in fiber diameters due to Ni2+ content. Core loss mapping using electron energy loss spectroscopy confirmed an even distribution of titanium and relatively uniform nickel in the fibers. It was found that doping with 0.5 mol.% Ni2+ decreased the rutile content, while doping with 1 mol.% Ni2+ resulted in a pure anatase phase with a significantly increased specific surface area (36.6 m2/g). Further increase in Ni2+ content (3-10 mol.%) not only prolonged the response of TiO2 nanofibers to visible light, but also increased the specific surface area (49.5 m2/g), decreased crystallite size (7 nm), and increased rutile content in TiO2 (33 wt.%). Photoluminescence analysis revealed that doping TiO2 with different amounts of Ni2+ leads to a gradual decrease of emission spectra intensity and red shift in the maxima positions. The XPS results confirmed that as the Ni2+ content enlarged, the Ti2+ and Ti3+ content increased significantly, effectively promoting the formation of oxygen vacancies. Raman analysis showed that an increase in nickel content (3-5 mol.%) led to a decrease and shift in peak intensity due to Ti3+ formation and also the possible presence of NiTiO3 phases. HRTEM analysis showed that Ni was doped into the substitution sites of both the anatase and rutile TiO2 lattice but had a stronger influence on the distortion of the anatase phase. The obtained results indicate that Ni-doped TiO2 nanofibers are good candidates for photocatalytic applications.

AB  - Infections with phytoplasma present one of the most significant biotic stresses influencing
plant health, growth, and production. The phytoplasma ‘Candidatus Phytoplasma solani’ infects
a variety of plant species. This pathogen impacts the physiological and morphological characteristics of plants causing stunting, yellowing, leaf curling, and other symptoms that can lead to significant economic losses. The aim of this study was to determine biochemical changes in peony (Paeonia tenuifolia L.), mint (Mentha × piperita L.), and dill (Anethum graveolens L.) induced by ‘Ca. Phytoplasma solani’ in Serbia as well as to predict the impact of the biotic stress using artificial neural network (ANN) modeling. The phylogenetic position of the Serbian ‘Ca. Phytoplasma solani’ strains originated from the tested hosts using 16S rRNA (peony and carrot strains) and plsC (mint and dill strains) sequences indicated by their genetic homogeneity despite the host of origin. Biochemical parameters significantly differed in asymptomatic and symptomatic plants, except for total anthocyanidins contents in dill and the capacity of peony and mint extracts to neutralize superoxide anions and hydroxyl radicals, respectively. Principal Component Analysis (PCA) showed a correlation between different chemical parameters and revealed a clear separation among the samples. Based on the ANN performance, the optimal number of hidden neurons for the calculation of TS, RG, PAL, LP, NBT, •OH, TP, TT, Tflav, Tpro, Tant, DPPH, and Car was nine (using MLP 8-9-13), as it produced high r2 values (1.000 during the training period) and low SOS values. Developing an effective early warning system for the detection of plant diseases in different plant species is critical for improving crop yield and quality.

AB  - Healthy dietary habits with abundant fruit consumption may reduce prevalence and positively affect development and progression of various chronic diseases including obesity and insulin-resistance related diseases. Strawberry (Fragaria × ananassa Duch.) represent a valuable source of vitamins, minerals, fatty acids, dietary fiber, and various bioactive polyphenolic compounds such as anthocyanins and flavonoids which are known for their antioxidant and anti-inflammatory activities. In this study we evaluated the effect of newly introduced strawberry cultivar „Aprika” supplemented in the form of lyophilized powder, on obesity-related metabolic alterations in high-fat-diet fed mice. We hypothesized that chronic (8 weeks) supplementation of lyophilized strawberries in the amount comparable to two servings per day in humans, would ameliorate insulin resistance associated with obesity in C57BL/6 mice. Furthermore, we hypothesized that strawberry meal consumed at 7PM i.e. before active feeding period of mice (which corresponds to early breakfast in humans) would induce more pronounced beneficial effects compared to meal consumed at 7AM i.e. at the end of the active feeding period (which corresponds to late dinner in humans). High fat diet induced hyperglycaemia, hyperinsulinaemia, insulin resistance and obesity; and disturbed hepatic insulin signaling. Lyophilized strawberries, only when consumed before feeding period, reduced body weight gain and improved insulin sensitivity induced by high-fat diet (evidenced by lower area under the curve after an intraperitoneal GTT, reduced serum insulin levels and an insulin resistance index (IR-HOMA). Strawberry meals consumed after active feeding period had no such effect. However, strawberries, regardless of the time of consumption, restored protein level of Insulin receptor substrate 1 (IRS1) in the liver and increased hepatic antioxidant enzymes level. In conclusion, strawberries improve insulin sensitivity and raise hepatic antioxidant capacity in mouse model of diet induced obesity. Nevertheless, more beneficial effects were achieved when strawberries were consumed before active feeding period, as an early breakfast

abstract = "Healthy dietary habits with abundant fruit consumption may reduce prevalence and positively affect development and progression of various chronic diseases including obesity and insulin-resistance related diseases. Strawberry (Fragaria × ananassa Duch.) represent a valuable source of vitamins, minerals, fatty acids, dietary fiber, and various bioactive polyphenolic compounds such as anthocyanins and flavonoids which are known for their antioxidant and anti-inflammatory activities. In this study we evaluated the effect of newly introduced strawberry cultivar „Aprika” supplemented in the form of lyophilized powder, on obesity-related metabolic alterations in high-fat-diet fed mice. We hypothesized that chronic (8 weeks) supplementation of lyophilized strawberries in the amount comparable to two servings per day in humans, would ameliorate insulin resistance associated with obesity in C57BL/6 mice. Furthermore, we hypothesized that strawberry meal consumed at 7PM i.e. before active feeding period of mice (which corresponds to early breakfast in humans) would induce more pronounced beneficial effects compared to meal consumed at 7AM i.e. at the end of the active feeding period (which corresponds to late dinner in humans). High fat diet induced hyperglycaemia, hyperinsulinaemia, insulin resistance and obesity; and disturbed hepatic insulin signaling. Lyophilized strawberries, only when consumed before feeding period, reduced body weight gain and improved insulin sensitivity induced by high-fat diet (evidenced by lower area under the curve after an intraperitoneal GTT, reduced serum insulin levels and an insulin resistance index (IR-HOMA). Strawberry meals consumed after active feeding period had no such effect. However, strawberries, regardless of the time of consumption, restored protein level of Insulin receptor substrate 1 (IRS1) in the liver and increased hepatic antioxidant enzymes level. In conclusion, strawberries improve insulin sensitivity and raise hepatic antioxidant capacity in mouse model of diet induced obesity. Nevertheless, more beneficial effects were achieved when strawberries were consumed before active feeding period, as an early breakfast",

AB  - The impact of pruning techniques on the plant growth, yield components and fruit quality
traits of substrate-grown highbush blueberry (Vaccinium corymbosum) cultivar 'Bluecrop'
were evaluated over four years (2019-2022). The orchard was planted in the village of Gruža 
(Knić municipality, Serbia) in the spring of 2017 with 5-year-old nursery plants using 113 l 
polypropylene pots spaced 0.8 m apart in a row and 3.0 m between rows (4,170 plants/ha). At 
the onset of the trial the ‘Bluecrop’ plants were 8 years old. The two pruning techniques were 
applied: i) conventional pruning (CP) - removal of the most unproductive canes at the center
of the canopy, and weak and excessively fruiting shoots from the top of bushes, and ii) 
sectorial pruning (SP) - only removal of basal canes in ¼ of the canopy each year. The 
average number of basal canes per bush was significantly lower in SP than in the CP 
treatment (14.4 vs. 17.4 canes bush-1
, respectively). SP plants had thinner canes than CP 
plants, which increased over the years of the study and reached a maximum diameter of 11.12 
mm in 2022. CP had a positive influence on fruit yield (5.98 kg bush-1
), which was associated 
with a 20% higher number of fruits per bush than in sectorial pruned plants. The fruit yield 
increased in the first three years of the study, reaching a maximum value in 2021 (7.57 kg per 
bush), whereas an opposite trend was observed in average fruit weight over the years, with the 
lowest value reached in the last harvest year (1.81 g). Fruit weight and soluble solids content 
were not affected by the pruning method, while the content of total acids, total anthocyanins 
and total phenolics were significantly higher in fruit harvested from the SP treatment (0.70%, 
37.04 mg eq mvd-3-G /100 g FW and 1.18 mg eq GA/g FW, respectively) along with the total 
antioxidant capacity (8.39 mg eq AsA /g FW).

AB  - The soybean is recognized worldwide as one of the most important crops due to its protein- and
oil-rich seeds. Several beneficial bacterial strains, including those of the genus Pseudomonas, are
known to increase plant yield and disease tolerance. The aim of this study was to test the potential of 15 strains of Pseudomonas spp. to promote soybean growth under field conditions. Strains were identified based on 16S rRNA and gyrB sequences, and strains belonging to risk group 1 were further analyzed. Selected strains were tested for plant growth-promoting (PGP) properties, biofilm formation and in vitro antimicrobial activity against various fungal pathogens. PGP activity indicators of the selected strains were evaluated on soybean plants grown in fertilizer-free soil and in soil treated with 70% and 100% fertilizers. Three Pseudomonas spp. strains, P. putida VB131A, P. fulva VB134B and P. rhodesiae VB143S, were selected as PGP candidates. All three strains showed the ability to produce IAA and solubilize phosphorus, while only P. rhodesiae VB143S showed strong lipase and protease activity. Only P. fulva VB134B showed the ability to
produce biofilm and hydrogen cyanide. All three strains showed in vitro antifungal activity against
Alternaria infectoria. P. fulva VB134B and P. rhodesiae VB143S showed antifungal activity against
Alternaria alternata and P. putida VB131A and P. rhodesiae VB143S against Epicoccum nigrum. Only P. fulva VB134B showed activity against Monilinia laxa. Statistically significant differences in
plant height were not observed regardless of the strain or soil treatment used. In terms of first
pod height, the P. fulva VB134B treatment was most effective when applied to soybeans grown
in 100% fertilized soil. In contrast, plants treated with P. rhodesiae VB143S and grown in 100% fertilized soil had the highest number of branches and pods per plant.

AB  - In August 2020, the unusual appearance of crown gall symptoms was observed on the
tobacco plants (hybrid PVH2310) grown in fields in the Golubinci (Srem district, Serbia) locality. The causal agent isolated from galls located on tobacco roots formed circular, convex, and glistening light blue colonies, and then dark to olive-green-colored bacterial colonies on a semi-selective D1 medium. Molecular analysis based on multiplex PCR and multi-locus sequence analysis (MLSA) using concatenated sequences of the atpD, dnaK, glnA, and rpoB genes as well as 16S rRNA identified Serbian tobacco isolates such as Agrobacterium tumefaciens (biovar 1). Two duplex PCR methods confirmed the presence of the virD2 and virC genes in tobacco isolates. Pathogenicity tests performed on carrot discs and squash fruits resulted in tumor/gall formation after 12 to 16 days post inoculation, respectively. Pathogenicity was also confirmed on tobacco plants, where isolates caused tumor development 21−25 days after inoculation. API 50 CH generated results regarding the biochemical features of the Serbian tobacco isolates. As A. tumefaciens (biovar 1) as a cause of tobacco crown gall has previously been documented solely in Japan, there is presently no data on its wider occurrence. Therefore, this first detailed investigation of A. tumefaciens isolated from naturally infected tobacco in Serbia will contribute to a better understanding of it at the global level.

AB  - From productive and ecological point of view, Quercus robur L. is an extremely important species and the investigation of its anatomical properties is very significant in terms of its technical and technological utilization. The paper deals with the analysis of the wood fiber characteristics (fiber length, fiber lumen width, double-cell wall thickness, Runkel ratio) of mature pedunculate oak trees in the non-flooded (Management Unit "Vinična-Žeravinac-Puk") and flooded area (Management Unit "GVO 83 b"). One of the aims of the study is to determine the wood fiber quality and the possibility of use in paper and pulp production. When the mean values of the analysed anatomical characteristics are compared, the results show slightly higher values in the non-flooded area, except for the Runkel ratio. The radial pattern of the investigated characteristics depending on the age shows growth in the non-flooded area, while the same tendency in the flooded area was found for the fiber length only. It was recorded that fiber lumen width, double-cell wall thickness and Runkel ratio decreased in the final annual rings. The wood fiber quality for use in pulp and paper production is the greatest in the juvenile zone, unlike sapwood zone, regardless of the site conditions.

AB  - Silicon (Si) is a widely recognized beneficial element in plants. With the emergence of nanotechnology in agriculture, silicon nanoparticles (SiNPs) demonstrate promising applicability in sustainable agriculture. Particularly, the application of SiNPs has proven to be a high-efficiency and cost-effective strategy for protecting plant against various biotic and abiotic stresses such as insect pests, pathogen diseases, metal stress, drought stress, and salt stress. To date, rapid progress has been made in unveiling the multiple functions and related mechanisms of SiNPs in promoting the sustainability of agricultural production in the recent decade, while a comprehensive summary is still lacking. Here, the review provides an up-to-date overview of the synthesis, uptake and translocation, and application of SiNPs in alleviating stresses aiming for the reasonable usage of SiNPs in nano-enabled agriculture. The major points are listed as following: (1) SiNPs can be synthesized by using physical, chemical, and biological (green synthesis) approaches, while green synthesis using agricultural wastes as raw materials is more suitable for large-scale production and recycling agriculture. (2) The uptake and translocation of SiNPs in plants differs significantly from that of Si, which is determined by plant factors and the properties of SiNPs. (3) Under stressful conditions, SiNPs can regulate plant stress acclimation at morphological, physiological, and molecular levels as growth stimulator; as well as deliver pesticides and plant growth regulating chemicals as nanocarrier, thereby enhancing plant growth and yield. (4) Several key issues deserve further investigation including effective approaches of SiNPs synthesis and modification, molecular basis of SiNPs-induced plant stress resistance, and systematic effects of SiNPs on agricultural ecosystem.

AB  - U okviru ove doktorske disertacije je ispitan uticaj koncentracije dopanta na svojstva BaCe1−xInxO3–δ (BCI, x = 0,05; 0,10; 0,15; 0,20; 0,25; 0,30; 0,35 i 0,40) kao protonskog provodnika. Struktura i fazni sastav sintetisanih prahova dobijenih metodom samosagorevanja su utvrđeni rendgenskom difrakcionom analizom, pri čemu je pokazano da prahovi sa ≥ 25 % (mol.) indijuma sadrže In2O3 kao sekundarnu fazu. Optimizacijom postupka sinterovanja je utvrđeno da je termički tretman na 1300 °C tokom 5 h optimalan za dobijanje guste neporozne keramike (98 % teorijske vrednosti). Mikrostruktura je analizirana skanirajućom elektronskom mikroskopijom (SEM). Povećanje temperature sinterovanja dovodi do nastanka većih zrna, dok povećanje koncentracije indijuma do 25 % (mol.) dovodi do porasta zrna, a iznad te koncentracije nema daljeg uticaja na veličinu zrna. Izlaganjem sinterovanog uzorka atmosferi CO2 tokom 5 h na 700 °C je pokazano da indijum u potpunosti suzbija degradaciju BaCeO3 već u koncentraciji od 15 % (mol.). Električnim merenjima u atmosferi vlažnog vodonika je utvrđeno da maksimalna ukupna provodljivost iznosi 5 × 10−3 S cm–1 na 700 °C za uzorak BaCe0,75In0,25O3–δ (BCI25), zbog čega je ovaj materijal odabran kao najbolji kandidat za elektrolit gorivne ćelije na bazi oksida u čvrstom stanju. Dobijena gorivna ćelija Ni-BaCe0,75In0,25O3−δ║BaCe0,75In0,25O3−δ║LSCF-BaCe0,75In0,25O3−δ (LSCF = lantan-stroncijum-kobalt-gvožđe-oksid, La0,8Sr0,2Co0,8Fe0,2O3) je pokazala maksimalnu gustinu izlazne snage od 264 mW cm–2 na 700 °C, koristeći vlažan vodonik kao gorivo. Ovakav rezultat ukazuje na stabilnost i funkcionalnost BCI25 kao elektrolita za gorivne ćelije.
Ispitivanjem električnih svojstava BCI25 u atmosferama različitog sastava je uočeno da dolazi do brze promene impedanse prilikom promene parcijalnog pritiska vodene pare, što čini ovaj materijal pogodnim za primenu kao visokotemperaturnog senzora vodene pare. Senzorska svojstva BCI25 u vidu poroznog filma i sinterovane keramike su ispitana u temperaturnom opsegu 250 °C – 700 °C. Film debljine 30 μm, napravljen od praha kalcinisanog na 1050 °C, je pokazao osetljivost uporedivu sa osetljivošću sinterovanog uzorka, ali sa značajno kraćim vremenom odziva i oporavka. Pokazalo se da je najbolja osetljivost senzora na temperaturi od 500 °C. Osetljivost filma se postepeno smanjivala sa smanjenjem parcijalnog pritiska vodene pare pH2O, ali je bila značajna i pri parcijalnom pritisku vodene pare od 200 Pa. Pad provodljivosti je zavisio logaritamski od parcijalnog pritiska vodene pare sa nagibom od 0,52 što je blisko tipičnoj vrednosti za protonski tip provođenja u tom temperaturnom opsegu. Posle nekoliko ciklusa, test ponovne upotrebe je pokazao skoro nepromenjen odnos između impedanse u suvoj i vlažnoj atmosferi (pH2O = 2,34 kPa), što je ukazalo na dobru stabilnost i osetljivost BCI25 kao potencijalnog visokotemperaturnog senzora vodene pare.

AB  - Elevated concentrations of heavy metals result in soil degradation, a reduction in plant
yields, and a lower quality of agricultural products, which directly endangers people, animals, and
the ecosystem. The potential of three clones of Salix alba (347, NS 73/6, and B-44) and one genotype of
S. viminalis for the phytoextraction of heavy metals was investigated, with the aim of identifying the
most physiologically suitable willow genotypes for use in soil phytoremediation. The experiment was
placed on the contaminated soil substrate collected in Kolubara Mining Basin (Serbia), enriched by
high loads of heavy metal salts, and a control medium. Significant differences in the concentrations
of heavy metals were recorded between the contaminated and control plant material, especially
when it comes to nickel (Ni), copper (Cu), cadmium (Cd), and lead (Pb), confirming that S. alba and
S. viminalis are hyperaccumulator species of heavy metals. Clone 347 shows the greatest uptake of
Cd and chromium (Cr), and clone B-44 takes up these metals only to a lesser extent, while clone
NS 73/6 shows a less pronounced uptake of Cr. The roots have the greatest ability to accumulate
Ni and Pb, Cu is absorbed by all plant organs, while Cd is absorbed by the leaves. The organ that
showed the greatest ability to accumulate heavy metals was the root, which means that willows have
a limited power to translocate heavy metals to above-ground organs. The studied genotypes of S. alba
have a higher potential for the phytostabilization of Cu and Cd, as well as the phytoextraction of
Cd, compared with S. viminalis. The results confirm the assumption of differences between different
willow genotypes in terms of the ability to phytoextract certain heavy metals from soil, which is
important information when selecting genotypes for soil phytoremediation.

AB  - Ni foam is an extensively used current collector and substrate in investigations of electrochemically active materials such as supercapacitors and electrocatalysts for oxygen and hydrogen evolution reactions. This material is relatively cheap, porous, and conductive and has a large specific surface area, all of which make it a good substrate. We investigated Ni-Mg ferrites and NiMn2O4 as active materials for electrochemical energy storage. These materials, when loaded on Ni foam, gave promising capacitance values: 172 F/g (at 2 mV/s) for NiMn2O4 in 6 M KOH and 242 F/g (at 2 mV/s) for MgFe2O4 in 3 M KOH. Nevertheless, during the authors’ work, many experimental problems occurred. Inconsistencies in the results directed further investigation towards measuring the capacitance of the active materials using GCE and platinum electrodes as substrates to discover if Ni foam was the culprit of the inconsistencies. When non-nickel substrates were used, both NiMn2O4 and MgFe2O4 showed reduced capacitance. Experimental problems associated with the utilization of Ni foam as a substrate for active materials in supercapacitor electrodes are discussed here, combined with other problems already addressed in the scientific literature

AB  - In the paper was analysed the influence of three different container types, used for
cultivation of Pinus nigra and Pinus sylvestris seedlings, on dimensions of their anatomical
(resin ducts width, resin ducts number, tracheid number, tracheid width, wood rays height) and
morphological (height, root collar diameter, sturdiness coefficient) elements, and on proportion
of wood, bark and pith, as well. Two-factorial ANOVA showed that container type affects a lot
all investigated anatomical traits by both species, but on the other side, these species varied
between each other just in terms of tracheid width and wood rays height. Based on descriptive
statistics, significantly lower values of all studied anatomical elements were recorded by
biodegradable compared to plastic containers. As for P. nigra seedlings, they showed the best
anatomical performance in Plantagrah I, while Hiko V-120 SS was the most suitable for
P. sylvestris. The highest proportion of pith and bark was recorded in biodegradable container.
As for morphological parameters, such as height and root collar diameter, higher values were
recorded by plastic containers.

cultivation of Pinus nigra and Pinus sylvestris seedlings, on dimensions of their anatomical
(resin ducts width, resin ducts number, tracheid number, tracheid width, wood rays height) and
morphological (height, root collar diameter, sturdiness coefficient) elements, and on proportion
of wood, bark and pith, as well. Two-factorial ANOVA showed that container type affects a lot
all investigated anatomical traits by both species, but on the other side, these species varied
between each other just in terms of tracheid width and wood rays height. Based on descriptive
statistics, significantly lower values of all studied anatomical elements were recorded by
biodegradable compared to plastic containers. As for P. nigra seedlings, they showed the best
anatomical performance in Plantagrah I, while Hiko V-120 SS was the most suitable for
P. sylvestris. The highest proportion of pith and bark was recorded in biodegradable container.
As for morphological parameters, such as height and root collar diameter, higher values were
recorded by plastic containers.",

AB  - BACKGROUND
Fungi absorb and solubilize a broad spectrum of heavy metals such as vanadium (V), which makes them a main route of its entry into the biosphere. V as vanadate (V5+) is a potential medical agent due to its many metabolic actions such as interaction with phosphates in the cell, and especially its insulin-mimetic activity. Antidiabetic activity of V-enriched fungi has been studied in recent years, but the biological and chemical bases of vanadium action and status in fungi in general are poorly understood, with almost no information on edible fungi. 
METHODS
This manuscript gives a deeper insight into the interaction of V5+ with Coprinellus truncorum, an edible autochthonous species widely distributed in Europe and North America. Vanadium uptake and accumulation as V5+ was studied by 51V NMR, while the reducing abilities of the mycelium were determined by EPR. 31P NMR was used to determine its effects on the metabolism of phosphate compounds, with particular focus on phosphate sugars identified using HPLC.
RESULTS
Vanadate enters the mycelium in monomeric form and shows no immediate detrimental effects on intracellular pH or polyphosphate (PPc) levels, even when applied at physiologically high concentrations (20 mM Na3VO4). Once absorbed, it is partially reduced to less toxic vanadyl (V4+) with notable unreduced portion, which leads to a large increase in phosphorylated sugar levels, especially glucose-1-phosphate (G1P) and fructose-6-phosphate (F6P).
CONCLUSIONS
Preservation of pH and especially PPc reflects maintenance of the energy status of the mycelium, i.e., its tolerance to high V5+ concentrations. Rise in G1P and F6P levels implies that the main targets of V5+ are most likely phosphoglucomutase and phosphoglucokinase(s), enzymes involved in early stages of G6P transformation in glycolysis and glycogen metabolism. This study recommends C. truncorum for further investigation as a potential antidiabetic agent.

AB  - Complex impedance spectra at room temperature in the frequency range of 8 Hz—5 MHz were measured on freshly cut leaf sections of the Aloe vera plant by AC impedance spectroscopy. They were analyzed using a classical 'brickwork' equivalent circuit composed of grain and grain boundary contributions commonly applied to solid-state materials. The obtained grain resistance/capacitance was 0.4 MΩ/72 pF and grain boundary resistance/ capacitance was 66.4 MΩ/50 nF. The determined conductivity changed according to the Jonscher power law with σDC of 4.02 · 10–5 (Ωm)−1 and frequency constant of 0.92 characteristic for hopping as the conduction mechanism. Analysis of dielectric permittivity and electric modulus confirmed the non-Debye relaxation behavior. Nyquist plots for electric modulus revealed conductivity relaxation in the low frequency attributed to grain boundaries and impedance modulus displayed dielectric relaxation in the high frequency region associated with grains. A correlation has been established among the investigated parameters, morphology, and EIS-derived simulated parameters.

AB  - Pharmaceutical and industrial utilization of synthetic chemicals has an immerse impact
on the environment. In that sense, novel chemicals with potential for industrial
application should be investigated for their behavior in reactions with hydroxyl radical,
simulating AOPs (Advanced Oxidation Processes). AOPs are known for being highly
effective in wastewater management and natural water remediation. In this paper,
exhaustive research on the radical scavenging activity of a newly synthesized
coumarin derivative (4HCBH), as a representative of the series of coumarin-
benzohydrazides with high antioxidative potential was conducted. This study took into
consideration the pH value range significant for practically all living organisms (pH=7.0-
8.5). According to the experimentally obtained results, the 4HCBH showed an increase
in radical scavenging activity, following the slight increase in pH values, which
suggested that the formation of anionic form of 4HCBH is responsible for its antiradical
activity. Further investigations led to the postulation of a novel mechanistic approach
called Sequential Proton Loss Electron Transfer – Radical-Radical Coupling (SPLET-
RRC), in which, by a series of steps, a new, stable compound was formed.
Furthermore, it was demonstrated that the product generated through SPLET-RRC
showed lower toxicity than the parent molecule.

AB  - Pure phase orthorhombic pseudobrookite (Fe2TiO5) was synthesized using a
modified sol-gel method. Bulk samples were obtained by uniaxial pressing of the
obtained powder into compacts sintered at 900 oC for 2 h. A noticeable NTC
thermistor effect was noted with a B20/55 value of 5747 K and high resistivity of 45
Mcm at 25 oC. A non-linear current-voltage characteristic was observed in the
voltage range (0.2–1100 V) at room temperature (25 oC). Non-saturated (lossy) P-E
loops were obtained at both measured frequencies (100 Hz and 1 kHz) more
expressed for the higher measured frequency, with the maximal polarization of
0.291 mikroC/cm2 and remanent polarization of 0.123 mikroC/cm2 for 20 kV/cm2 and 1 kHz.
Complex impedance measured in the temperature range 20–330 oC enabled analysis
of the contribution of grain boundary and grains to the conduction mechanism. Bulk
conductivity data determined in this temperature range was analyzed using
Jonscher’s universal dielectric response model and showed that the conduction
process followed the nearest neighbor hopping conduction mechanism.

AB  - In this work, titanium dioxide (TiO2) nanofibers doped with 0.5–5 mol% 
zirconium ions (Zr4+) were synthesized by combining the sol-gel process and 
electrospinning method, and calcined at 500 °C. The morphological, structural and 
optical properties of pure and Zr-doped TiO2 nanofibers were investigated. According to 
the XRD and FTIR analyses, the addition of Zr as a dopant suppressed the 
transformation of anatase to rutile phase. Scanning electron microscopy showed that all 
fibers were smooth, fragile and randomly oriented after the calcination process. HRTEM 
analysis revealed that Zr4+ ions were incorporated at the substitutional sites in the anatase 
TiO2 crystalline lattice. The photocatalytic efficiency for degradation of methylene blue 
(MB) was examined for both pure and Zr-doped TiO2 samples. Nanofibers doped with 
1% of Zr4+ ions have shown the highest photocatalytic activity of 98%, wich can be 
explained by considering lower PL intensity in the PL spectrum of this sample, 
indicating suppressed electron-hole recombination.
