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  - Pure and samarium (Sm3+) - or zirconium (Zr4+)-doped TiO2 nanofibers were synthesized by  electro- 
spinning method followed by calcination at 500 °C for 1 h. As-spun fibers were smooth, straight and 
continuous, whilst EDS analysis confirmed the fiber composition and incorporation  of  dopants  in  
the  fibers. Doping with Sm3+ and Zr4+ greatly inhibited the phase transformation of anatase to 
rutile, by surrounding of Sm3+ ions through formation of Ti-O-Sm bonds  and  by  replacement  of  
Ti4+  ions  with  larger Zr4+ ions. This was confirmed by HRTEM and SAED analysis. The size of 
nanofibers was determined to be 133 nm, 175 nm and 155 nm for pure, (0.5%)Sm3+:TiO2 and 
(1%)Zr4+:TiO2, respectively. After  cal- cination, TiO2 crystal lattice with interplanar spacing of 
0.353 nm of (101) crystal  plane  was not  significantly disturbed by Sm doping whilst  crystal  
lattice  spacing  of  0.357  nm  of  (101)  planes  of anatase  phase  in  case  TiO2:1.0%Zr4+,  
significantly  differs  from  the  value  of  pure  TiO2   (0.352  nm),  thus implying that Zr was 
doped into substitutional  sites  of  the  TiO2  lattice.  The  indirect  band  gaps  were 
calculated to be in the range  3.07–3.24  eV.  TiO2:0.5%Sm3+ and  TiO2:1.0%Zr4+ exhibited  higher  
specific surface area, of 47.1  and 59.4 m2/g, respectively, than pure TiO2  fibers (19.7 m2/g). 
Effects of Sm3+ and Zr4+ dopant content on the photodegradation efficiency of methylene blue (MB) 
were studied. TiO2:0.5%Sm3+ and TiO2:1.0%Zr4+ nanofibers have shown  the  highest  photocatalytic  
activity  of  97%  and 98%  with  constant  rates  0.01768  min−1  and  0.01939  min−1,  
respectively,  within180  min irradiation under

AB  - Designing cost-effective hydrogen evolution reaction (HER) electrocatalysts containing highly active, but expensive platinum group metals (PGMs) is key to the commercialization of polymer electrolyte membrane water electrolysis systems for green hydrogen production. Our recent investigations have shown that efficient and durable HER composite cathodes can be prepared by spontaneous deposition of PGM nanoparticles on self-aligned titania nanotube (TNT) arrays formed by anodization [1]. In this synthesis route, anatase TNTs are first cathodically protonated (H-TNT), and then used as the reducing agent for PGM ions at room temperature. Herein, we employ the galvanic displacement strategy to decorate H-TNT arrays with ultrafine Ir nanoparticles [2]. We demonstrate that transforming the top surface morphology of supporting TNT arrays from ordered open-top tubes to bundled nanowires (“nanograss”) is beneficial for exposing more Ir active centers during the HER operation. Consequently, applying very low concentrations of Ir(III) ions in the galvanic displacement step is sufficient to produce exceptionally active nanograss-modified Ir@TNT composites. An optimum Ir@TNT, possessing a low Ir loading of 5.7 μgIr cm–2, requires an overpotential of only –63 mV to reach a current density of –100 mA cm–2 and shows a stable long-term performance in a 1 M HClO4 solution. Computational simulations suggest that the hydrogen-rich TiO2 support not only strongly interacts with anchored Ir particles and weakens their H binding strength to a moderate level, but also actively provides hydrogen for rejuvenation of the Ir active sites at the Ir|H-TiO2 interface, thereby significantly enhancing HER catalysis.

AB  - Efficient cathodes for the hydrogen evolution reaction (HER) in acidic
water electrolysis rely on the use of expensive platinum group metals (PGMs). However, to
achieve economically viable operation, both the content of PGMs must be reduced and
their intrinsically strong H adsorption mitigated. Herein, we show that the surface effects of
hydrogenated TiO2 nanotube (TNT) arrays can make osmium, a so far less-explored PGM,
a highly active HER electrocatalyst. These defect-rich TiO2 nanostructures provide an
interactive scaffold for the galvanic deposition of Os particles with modulated adsorption
properties. Through systematic investigations, we identify the synthesis conditions (OsCl3
concentration/temperature/reaction time) that yield a progressive improvement in Os
deposition rate and mass loading, thereby decreasing the HER overpotential. At the same
time, the Os particles deposited by this procedure remain mainly sub-nanometric and
entirely cover the inner tube walls. An optimally balanced Os@TNT composite prepared at
3 mM/55 °C/30 min exhibits a record low overpotential (η) of 61 mV at a current density
of 100 mA cm−2, a high mass activity of 20.8 A mgOs
−1 at 80 mV, and a stable performance in an acidic medium. Density functional
theory calculations indicate the existence of strong interactions between the hydrogenated TiO2 surface and small Os clusters, which
may weaken the Os−H* binding strength and thus boost the intrinsic HER activity of Os centers. The results presented in this study
offer new directions for the fabrication of cost-effective PGM-based catalysts and a better understanding of the synergistic electronic
interactions at the PGM|TiO2 interface.

AB  - In this paper, 12-tungstenphosphoric acid (PWA) was synthesized in
combination with FeCl3 at room temperature (25 °C). At such manner, Fe3+ ion
exchange gave new 12-tungstenphosphoric salt of the transition metal iron
(FePW12O40×nH2O; Fe-PWA). Thermal analysis determined the temperature of
about 596 °C of the phase transition, i.e., the temperature at which the structure of
the Kegin anion is disturbed. Therefore, it was chosen temperature above the
breakdown of the Kegin anion of 650 °C, and which is required to obtain phosphate
tungsten bronzes (PWB) doped with iron (Fe-PWB). The sample was kept in the
oven for 10 min. Such obtained new Fe-PWB doped bronze was further investigated
by the X-ray powder diffraction (XRPD) and Rietveld methods. The XRPD patterns
of Fe-PWA and Fe-PWB were taken in the 3–90° 2θ angle range, and clearly reveal
crystallographic and structural differences between these two phases. Determined
unit-cell parameters of Fe-PWB obtained by the Rietveld method in the monoclinic
crystallographic system are as following: a0 = 7.53(2) Å; b0 = 7.51(1) Å; c0 =
7.64(1) Å; β0 = 89.7(2)° and V0 = 431(2) Å3. These unit-cell parameters were
compared with PWB, as well as other previously characterized doped bronzes (LiPWB and Ca-PWB). It can be concluded that inserting of the Fe3+ ion into the
PWB’s structure was undoubtedly proven, and have the most influence to the axis a0
(i.e. it significantly increased), angle β0 (i.e., it significantly decreased), and volume
V0 (i.e., it significantly increased). On the other hand, influence to the axis c0 is quite
smaller (i.e. it slightly decreased), whereas influence to the axis b0 is minor. Such
behavior is also very different in comparison to the Li-PWB and Ca-PWB.

AB  - Due to Li-ion batteries having become the main power source of most portable
electronic devices, their waste has also become a significant environmental problem.
To find batteries that would be environmentally friendly, this work examines Zn-ion
batteries in an aqueous solution of ZnCl2. The ZnMnO4 was synthesized by glycine
nitrate combustion of Zn(NO3)2, Mn(NO3)2 and glycine as a chelating agent [1]. The
structure of the material obtained was characterized by X-ray powder diffraction
(XRPD) showing a spinel structure; the morphology was characterized by scanning
electron microscopy (SEM) showing that nano-particles were obtained. The
electrochemical characterization was done by cyclic voltammetry in an aqueous
solution of ZnCl2. The mixture pasted on the glossy carbon electrode was prepared
by mixing the cathode material, graphite and polyvinyl diene difluoride (PVDF) in a
ratio 85:10:5 [2]. Due to the low discharge capacity obtained of ~14 mAh g-1 for 5
mV s-1, further examination was done by adding 1 ml of 1M Mn(NO3)2 into 10ml of
a saturated aqueous solution of ZnCl2. After adding the Mn(NO3)2 , the discharge
capacity increased from ~14 mAh g-1 to ~65 mAh g-1 at the same polarization rate,
making this additive a promising one for aqueous Zn-ion batteries. Further
investigation needs to be directed to adding the same additive in larger amounts
compared to 1ml to the same volume of the electrolyte. The results obtained suggest
the aqueous Zn-ion battery described in this work to be a potentially promising
“green” battery that may replace harmful commercial organic Li-ion batteries.

AB  - The devolatilization process is the initial step in the coal combustion. Devolatilization research
was performed on a wire-mesh reactor in inert gas, at the atmospheric pressure. Two different
sets of feed coal samples of various particle diameters (0.50<х<1.00 mm; 0.25<x<0.50 mm;
0.1<x<0.25 mm; x<0.1 mm) from the Kolubara and Kostolac mines were used for research.
Lignite samples were spread in a thin layer a few particles thick, over electrically heated
stainless steel wire mesh and rapidly heated at four different temperature stages (300oC, 500oC,
700oC, 900oC). Maceral analysis and rank deternination were performed on 32 combustion
residues and 8 lignite samples following the classification developed by ICCP for lignite,
bituminous coal and coal chars.

AB  - As commercial Li-ion batteries are chiefly composed of a toxic and flammable
electrolyte, as well as that Li itself is also toxic and not economical for widespread
use due to its rare metal nature, the aim of this work is to create an aqueous Zn-ion
battery that contains the same cathode material as used in Li-ion batteries. The
materials ZnMn2O4 and ZnCr0.15Mn1.85O4 were synthesized through glycine nitrate
combustion. The initial material ZnMn2O4 was doped with Cr3+ in order to diminish
Jan-Teller distortion which prevents of Zn2+ ions to fully intercalate into their
original sites of crystal lattice. The materials were characterized by X-ray powder
diffraction (XRPD) and scanning electron microscopy (SEM), while the
electrochemical properties were examined through cyclic voltammetry in aqueous
solutions of ZnCl2. The capacities obtained for the cyclic voltamogrammes recorded
at 10 mVs-1 and 50 mVs-1 showed that cathode capacities for ZnMn2O4 amounted to
be 12.4 mAhg-1 for 10 mVs-1, as well as 4.8 mAhg-1 for 50 mVs-1. The
ZnCr0.15Mn1.85O4 demonstrated 45.3 mAhg-1 for 10 mVs-1, as well as 12.6 mAhg-1
for 50 mVs-1. The results obtained for the capacities of the original and doped
material indicate that doping with Cr2+ partly diminishes the Jan Teller effect and
facilitates the intercalation of Zn2+ ions.

molecules could be extracted using methanol which is unfortunately harmful to living beings. To
surpass the problem of solvent toxicity, in this paper, we have incorporated methanol extracts of
two novel strawberry cultivars into liposomes. Our results show that both extracts possess
significant antiradical activity towards hydroxyl and DPPH radicals, unaltered by lipids from
liposome membranes. These results indicate that otherwise toxic extracts could easily be turned into a promising pharmaceutical product.

AB  - Phenolic compounds of 25 newly introduced strawberry cultivars were profiled using spectrophotometry, electron paramagnetic resonance (EPR) spectroscopy, and high-performance liquid chromatography-mass spectrometry. Total phenolic and anthocyanin content (TPC and TACY, respectively), as well as vitamin C, and concentrations of individual phenolic compounds in fruits were evaluated to identify the most promising cultivars according to their phenolic profile. The highest values of TPC, TACY, and vitamin C were recorded in ´Premy´ (1.53 mg eq GA g-1 FW), ´Sandra´ (30.60 mg eq Pg-3-g 100 g-1 FW) and ´Laetitia´ (56.32 mg 100 g-1 FW), respectively. The DPPH and •OH radicals scavenging activity of fruit methanolic extracts was estimated using EPR spectroscopy. All cultivars are almost uniformly effective in the scavenging of •OH radical, while ´Tea´, ´Premy´, and ´Joly´ were marked as highly potent cultivars (over 70%) in terms of DPPH-antiradical activity. Specific peroxidase activities were the highest in ´Garda´, ´Federica´, and ´Rumba´ (0.11, 0.08, and 0.06 U mg-1 prot, respectively). ´Laetitia´, ´Joly´, ´Arianna´, ´Tea´, and ´Mila´ cultivars were distinguished from others as the richest concerning almost all flavonoids and phenolic acids, including some other parameters of bioactivity. These cultivars could be recommended to consumers in terms of fruit as a functional food.

Sa sadržajem Ir od svega 5.7 μg cm–2, najbolja Ir@TNT katoda pokazala je prenapetost od –63 mV na gustini struje od –100 mA cm–2, kao i izvrsnu katalitičku i strukturnu stabilnost u rastvoru 1 M HClO4. Teorijske simulacije sugerišu da hidrogenovani TiO2 nosač stabilizuje istaloženi Ir, omogućava umerenu jačinu veze Ir–Hads i aktivno regeneriše površinu Ir tokom izdvajanja vodonika.

AB  - To protect the environment from potentially hazardous components from commercial Li-ion
batteries (i.e., contain toxic and flammable electrolytes as well as Li is uneconomical and a rare earth
metal), a viable alternative need to be found for the components of these batteries. Thus, our focus is
on replacement of an organic electrolyte using an aqueous one. Additionally, the work also examines
the replacement of Li with Zn as production of Zn-based cathode material is more economical compared
to Li and less toxic. Due to occurrence of the Ian Teller effect in ZnMn2O4, Mn3+ ions are partially
replaced with Cr3+ ions to diminish this phenomenon and to obtain a higher capacity. Namely, due to
the Ian-Teller distortion, not all cations of Zn2+ ions may intercalate in the crystal lattice sites. When the
Ian-Teller effect lowers, more Zn2+ ions may intercalate into sites; thus, a higher capacity may be
obtained. The materials ZnMn2O4 and ZnCr0.15Mn1.85O4 were synthesized by glycine nitrate combustion
method. The materials were characterized by XRPD, SEM, EDS and cyclic voltammetry. The aqueous
solutions of ZnCl2 were used as electrolytes as potentially more ecological alternatives compared to the
organic ones already commercially used. The cathode capacities obtained for the ZnMn2O4 under 5 mV
s-1 and 20 mV s-1 ranged from 17.7 mA h g-1 to 6.9 mA h g-1. The cathode capacities obtained for
ZnCr0.15Mn1.85O4 under 5mV s-1 and 20 mV s-1 ranged from 86.3 mA h g-1 and 24.6 mA h g-1,
respectively. Over the intercalation and deintercalation process of the Zn2+ ions into the
ZnCr0.15Mn1.85O4, a release of oxygen occurred. The stable capacity obtained for both rates (5 mV s-1
and 20 mV s-1) indicates that the ZnCr0.15Mn1.85O4 material is applicable for both rates used. Further
examination of the ZnMn2O4 material must be conducted in terms of increasing the capacity through its
doping with other ions or its use in an aqueous solution of other salts.

AB  - BACKGROUND Aflatoxin B-1 (AFB(1)) is the most dangerous of the mycotoxins that contaminate cereal seeds naturally. A stress lignin formation is linked with the accumulation of reactive oxygen species causing a change in the redox status and formation of stable organic radicals, constituting the first layer of defense. The relationship between AFB(1) and changes in lignin organic free radicals in seeds is not known, nor is the part of the seed that is more targeted. Using optical and electron paramagnetic resonance spectroscopy, we investigated AFB(1)-induced changes in lignin and organic free radicals in seeds, and whether the inner and outer seed fractions differ in response to increasing AFB(1). RESULTS Different changes in the content of lignin and free radicals with increasing AFB(1) concentrations were observed in the two seed fractions. There was a significant positive linear correlation (R = 0.9923, P = 0.00005) between lignin content and AFB(1) concentration in the outer fraction, and no correlation between the lignin content and the AFB(1) concentration in the inner fraction. We found a positive correlation between the area of the green spectral emission component (C4) and the AFB(1) concentration in the outer fraction. CONCLUSIONS To the best of our knowledge, the results showed, for the first time, that maize seed fractions respond differently to aflatoxin with regard to their lignin and organic free radical content. Lignin content and (C4) area may be reliable indicators for the screening of lignin changes against AFB(1) content in the seeds, and thus for seed protection capacity.

AB  - Recently, two different effects of phosphate tungsten (PWB) and phosphate
molybdenum (PMoB) bronzes (obtained by thermal treatment), on oscillatory
Briggs-Rauscher (BR) dynamic have been found [1]. Although both are insoluble in
BR solution [2], the addition of different masses of PWB linearly decreases the BR
oscillation time, while the addition of different masses of PMoB had no effects on
the BR reaction. Furthermore, PWB has an identical role as metal catalyst Mn2+ in
BR reaction and for obtained behavior is probably responsible the different
mechanisms of heterogeneous catalysis of these bronzes in oscillatory reaction.
Therefore, a deeper investigation was done in order to find the major structural
characteristic of these two bronzes by using the XRPD method.
What is so different for these two bronzes, causing dissimilar effects in BR
reaction, is it “just” catalytic activity of central cation or there is something more?
The XRPD method confirmed very different structures of PWB and PMoB as
monoclinic and orthorhombic, respectively [3,4]. This work tries to connect the
structural properties of PWB and PMoB with BR oscillatory reaction responses,
expanding the usage of oscillatory reaction in material science and catalysis, in
general.

AB  - Indigo carmine (InC) is broadly used blue dye in different industrial area. This work aims to
obtain analytical curves for determination of InC in aqueous solutions. For such as purposes, two
methods were used: UV/VIS spectrophotometry and the kinetic method based on Briggs-
Rauscher (BR) oscillatory reaction, and compared in terms of methods sensitivity which
expressed as limit of detection (LOD) and limit of quantification (LOQ). To the best authors' knowledge, as candidate for proposed analytical method, the BR oscillatory reaction was applied
for the first time to InC quantification. The results obtained show that kinetic method using BR
oscillatory reaction has a quite lower LOD and LOQ making this method more acceptable to
determine an unknown concentration of InC dissolved in water, compared to UV/Vis
spectrophotometric method.

(ZMO) through the glycine-nitrate combustion. XRPD validates its phase characterization; electron microscopy confirmed the presence of single phase ZMO in the form of curvy and rod-shaped sub-micron sized
particles at an average of 113 nm. This work is novel for its electrochemical measurements of ZMO as a
cathodic material for alkali-ion batteries, performed by cyclic voltammetry in aqueous solutions of ZnCl2 and
NaNO3 ranging from 5 to 100 mV s–1 polarization rates, yielding stable capacities for both electrolytes. The
highest capacities were obtained for the polarization speed of 5 mV s–1 for both electrolytes. Their cathode
capacities were 11.3 and 27.2 mA h g–1 for ZnCl2 and NaNO3, respectively. Concerning Na-ions batteries,
the surface storage is the deciding factor due to the adsorption of Na+ ions on the λ-MnO2 phase. Unlike Znions, Na+ ions cannot intercalate into the spinel structured materials.

AB  - Indigo carmine is a commonly used industrial blue dye. To determine its concentration in a
commercially available food dye composed of a mixture of indigo carmine and D-glucose, this paper
characterizes it through (ATR, KBr) FTIR micro-Raman as well as UV/Vis and clock: Briggs–Rauscher
(BR) oscillatory reaction methods. The indigo carmine was detected in the bulk food dye only by
applying micro-Raman spectroscopy, indicating a low percentage of the indigo carmine present.
This research provides an improvement in the deviations from the experimental Raman spectrum as
calculated by the B97D/cc-pVTZ level of theory one, resulting in a better geometrical optimization of
the indigo carmine molecule compared to data within the literature. The analytical curves used to
determine indigo carmine concentrations (and quantities) in an aqueous solution of food dye were
applied by means of UV/Vis and BR methods. BR yielded significantly better analytical parameters:
100 times lower LOD and LOQ compared to commonly used UV/Vis. The remarkable sensitivity
of the BR reaction towards indigo carmine suggests that not only does indigo carmine react in an
oscillatory reaction but also its decomposition products, meaning that the multiple oxidation reactions
have an important role in the BR’s indigo carmine mechanism. The novelty of this research is the
investigation of indigo carmine using a clock BR reaction, opening new possibilities to determine
indigo carmine in other complex samples (pharmaceutical, food, etc.).

AB  - In this contribution, four new compounds synthesized from 4-hydroxycoumarin and tyramine/octopamine/norepinephrine/3-methoxytyramine are characterized spectroscopically (IR and NMR), chromatographically (UHPLC-DAD), and structurally at the B3LYP/6-311++G*(d,p) level of theory. The crystal structure of the 4-hydroxycoumarin-octopamine derivative was solved and used as a starting geometry for structural optimization. Along with the previously obtained 4-hydroxycoumarin-dopamine derivative, the intramolecular interactions governing the stability of these compounds were quantified by NBO and QTAIM analyses. Condensed Fukui functions and the HOMO-LUMO gap were calculated and correlated with the number and position of OH groups in the structures. In vitro cytotoxicity experiments were performed to elucidate the possible antitumor activity of the tested substances. For this purpose, four cell lines were selected, namely human colon cancer (HCT-116), human adenocarcinoma (HeLa), human breast cancer (MDA-MB-231), and healthy human lung fibroblast (MRC-5) lines. A significant selectivity towards colorectal carcinoma cells was observed. Molecular docking and molecular dynamics studies with carbonic anhydrase, a prognostic factor in several cancers, complemented the experimental results. The calculated MD binding energies coincided well with the experimental activity, and indicated 4-hydroxycoumarin-dopamine and 4-hydroxycoumarin-3-methoxytyramine as the most active compounds. The ecotoxicology assessment proved that the obtained compounds have a low impact on the daphnia, fish, and green algae population.

For this purpose, four cell lines were selected, namely human colon cancer (HCT-116), human adenocarcinoma (HeLa), human breast cancer (MDA-MB-231), and healthy human lung fibroblast (MRC-5) lines. A significant selectivity towards colorectal carcinoma cells was observed. Molecular docking and molecular dynamics studies with carbonic anhydrase, a prognostic factor in several cancers, complemented the experimental results. The calculated MD binding energies coincided well with the experimental activity, and indicated 4-hydroxycoumarin-dopamine and 4-hydroxycoumarin-3-methoxytyramine as the most active compounds. The ecotoxicology assessment proved that the obtained compounds have a low impact on the daphnia, fish, and green algae population.",

AB  - Larger Coulombic repulsion between divalent cations compared to the monovalent counterparts dictates the cation-cation distance in the central ion channel of quadruplexes. In this work, density functional theory and a continuum solvation model were employed to study bond energies of alkaline earth cations in adjacent cavities of the central ion channel. Four crystallized tetramolecular quadruplexes with various geometric constraints and structural motifs available in the Protein Data Bank were examined in order to understand how the cation binding affinities could be increased in aqueous solution. A cytosine quartet sandwiched between guanine quartets has a larger bond energy of the second alkaline earth cation in comparison with guanine and uracil quartets. Four highly conserved hydrogen-bonded water molecules in the center of the cytosine quartet are responsible for a higher electrostatic interaction with the cations in comparison with guanines' carbonyl groups. The reported findings are valuable for the design of synthetic quadruplexes templated with divalent cations for optoelectronic applications.

AB  - In this paper, we employed plasma electrolytic oxidation (PEO) of aluminum in a water solution of sodium tungstate (Na2WO4 center dot 2H(2)O) with the addition of the pure and Ce-loaded zeolites clinoptilolite and 13 X for the preparation of oxide coatings. The obtained coatings were characterized with respect to their morphologies and chemical and phase compositions using scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy, atomic force microscopy, and X-ray diffraction. The prepared coatings contained gamma-alumina, WO3, and metallic tungsten. The surface morphologies of the obtained coatings strongly depended on the PEO processing time; the roughness of all coatings increased with PEO time, while porosity decreased with PEO processing time as a result of microdischarge coalescence and growth. All coatings contained elements originating from the substrate and from the electrolytes. Coatings containing zeolites with Ce showed higher photoactivity than those with immobilized pure zeolites. The highest photocatalytic activity levels were observed for coatings containing immobilized Ce-exchanged clinoptilolite processed for 10 min. It was observed that both clinoptilolite and 13X zeolites improved the features of the PEO coatings in a similar manner, making natural and abundant clinoptilolite an excellent candidate for various applications.

AB  - Modifying commercial Li-ion batteries to become more environmentally friendly is of a growing concern. This paper provides an examination of a potential replacement for commercial cathode material using a naturally occurring purpurin in aqueous solutions of lithium and sodium salts. The purpurin is extracted from the Madder plant (Rubia tinctorum) and characterized through XRPD, FTIR, and SEM methods. The intercalation and de-intercalation capacities obtained for the purpurin as a cathode material in the aqueous solution of LiNO3 are approximately 40 mAh g(-1). Compared to the capacity of similar to 35 mAh g(-1) obtained for commercially used transition metal oxides in an aqueous solution of Li salt, results presented make the purpurin a promising material for the "green" development of Li-ion batteries. Although the initial purpurin capacity in NaNO3 solution is almost doubled (similar to 73 mA h g(-1)) compared to that of Li-salt, it is unstable and fades during cycling. The possible explanation of the electrochemical behavior of purpurin as the cathode material in aqueous solutions of Li and Na salts is discussed in detail.

AB  - Apoplastic antioxidative constituents (enzymes, primary and secondary metabolites, ROS) from different root zones of hydroponically grown maize (Zea mays L.) were investigated using a noninvasive isolation procedure: filter strip method. Filter strips were placed at specific positions on the root surface: apical zone (tip) and basal zone (base) to absorb apoplastic fluid. Three major classes of low-weight metabolites (organic acids, sugars, and phenolics) have been identified by HPLC-ECD. The longitudinal distribution of sugars and organic acids had the same pattern: higher concentration in the tip than the base, while it was vice versa for phenolics. The specific activities of guaiacol peroxidase, superoxide dismutase, and ascorbate peroxidase were higher in the apoplastic fluid from the root base than the tip, and their different isoforms were separated by isoelectric focusing. Electron paramagnetic resonance (EPR) spectroscopy coupled with the spin-trapping method using DEPMPO showed a persistent generation of hydroxyl radical in the root tip. In vivo EPR imaging of the whole maize root with membrane-permeable and impermeable aminoxyl spin-probes, enabling real-time detection of ROS formation within and outside the membranes, demonstrated ROS accumulation on the root surface, while endodermis and central cylinder were ROS free. For the first time in plant research, 2D EPR images enabled the direct demonstration of site-specific free radical production along the root. Highly sensitive analytical techniques combined with the filter strips, as a non-invasive tool, have increased our knowledge of metabolic processes occurring in the apoplast and their spatial-temporal changes in small regions of the intact root tissue.
