AB  - The mean ionic activity coefficients of NaCl in a ternary system {yNaCl + (1 – y)Na2HPO4}(aq)
were determined from measurements of the electromotive force (EMF) where the NaCl ionic strength
fraction was y = (0.3012; 0.4015; 0.5011; 0.5988; 0.7706; 0.8997) in the range of total ionic strength of the
solution Im = 0.0701–1.0161 mol kg–1 at temperature T = 298.15 K. A cell of the Na–ISE| ,Na2HPO4|AgCl|Ag, type was employed for the EMF measurements. The experimental results
from this work and the model of Pitzer’s were used to determine the mixing parameters. Good agreement
was found between the experimental and calculated values of the mean ionic activity coefficients of NaCl
with a standard deviation of fit 1.5 × 10–3. The values of the osmotic coefficients of the system {yNaCl +
(1 – y)Na2HPO4}(aq) were estimated on the basis of the determined parameters and compared with liter ature data. The differences in the osmotic coefficients between the estimated and experimental values were
negligible

AB  - Developing highly efficient semiconductor metal oxide (SMOX) sensors capable of accurate and fast responses to environmental humidity is still a challenging task. In addition to a not so pronounced sensitivity to relative humidity change, most of the SMOXs cannot meet the criteria of real-time humidity sensing due to their long response/recovery time. The way to tackle this problem is to control adsorption/desorption processes, i.e., water-vapor molecular dynamics, over the sensor’s active layer through the powder and pore morphology design. With this in mind, a KIT-5-mediated synthesis was used to achieve mesoporous tin (IV) oxide replica (SnO2-R) with controlled pore size and ordering through template inversion and compared with a sol-gel synthesized powder (SnO2-SG). Unlike SnO2-SG, SnO2-R possessed a high specific surface area and quite an open pore structure, similar to the KIT-5, as observed by TEM, BET and SWAXS analyses. According to TEM, SnO2-R consisted of fine-grained globular particles and some percent of exaggerated, grown twinned crystals. The distinctive morphology of the SnO2-R-based sensor, with its specific pore structure and an increased number of oxygen-related defects associated with the powder preparation process and detected at the sensor surface by XPS analysis, contributed to excellent humidity sensing performances at room temperature, comprised of a low hysteresis error (3.7%), sensitivity of 406.8 kΩ/RH% and swift response/recovery speed (4 s/6 s).

AB  - It is well known that titanium dioxide is usually used as a photocatalyst due to its
nontoxicity, low cost, and stability. Conductive polymer, polypyrrole (PPy) is also
appropriate for photocatalytic application being stable and easy to synthesize. The aim of
this study was to obtain TiO2/PPy composites reaching higher photocatalytic efficiency
compared to pure TiO2. Therefore, TiO2 was synthesized by the hydrothermal route,
while PPy was obtained by the chemical oxidative polymerization method. TiO2/x% PPy
nanocomposites (x = 0, 0.5, 1, 1.5, 3, 5 wt.%) were prepared by hand-mixing of powders
in agate mortar for 30 min in order to find the optimal PPy content. Obtained materials
were characterized by XRD, FTIR, TG/DSC, FESEM, and UV-Vis methods while their
photocatalytic activity was estimated towards degradation of Reactive Orange 16 dye
(RO16). A kinetic study was performed and a detailed mechanism of RO16
photocatalytic degradation in the presence of TiO2/PPy composites was proposed based
on scavenger tests. The results showed that, despite PPy addition, TiO2 was present in
anatase form in all samples with sufficiently small crystallites (around 26 nm) and
preserved structure with no significant deviations in unit cell parameters. The band gap
energy decreased with increasing of PPy content, from 3.14 eV for pure TiO2 to 2.94 eV
for TiO2/5% PPy. All the obtained nanocomposites demonstrated higher photocatalytic
activity than pure TiO2, whereby TiO2/1% PPy nanocomposite was the most efficient by
degrading 99.6% of the dye for 105 min under simulated solar light. Therefore, the
amount of 1 wt.% should be consider as optimal amount of PPy in a composite. It is
established that the photodegradation of RO16 using TiO2/PPy nanocomposites follows
pseudo-first kinetic order. RO16 photocatalytic degradation mechanism in the presence
of TiO2/PPy nanocomposites can be well described by direct Z-scheme heterojunction
which has never been reported for TiO2/PPy system.

AB  - In this work, the decoration of noble metal nanoparticles on a semiconductor
surface was used as a strategy to reach strong visible light absorption and efficient
electron-hole separation to enhance the photocatalytic activity of ZnO.
The Ag-modified ZnO nanopowders were obtained by the green synthesis. Zinc
acetate dihydrate with different silver nitrate content (0, 0.75, 1.5 and 3 mol%) was
dissolved in ethylene glycol in the presence of chitosan. The obtained mixtures in
the form of gel were heated at 150 °C for 2 h and subsequently calcined at 400 °C
for 1 h. The obtained samples were characterized by XRPD, FESEM, HRTEM, and
UV-vis techniques while the photocatalytic efficiency was tested by monitoring the
degradation of textile dyes Reactive Orange 16 (RO16), Acid Green 25 (AG25),
Mordant Blue 9 (MB9), and Ethyl Violet (EV) then compared with the commercial
ZnO nanopowder.
The results showed that the Ag/ZnO samples consisted of ZnO nanoparticles
with an average crystallite size of about 25 nm and Ag (20–30 nm) distributed on
the surface of ZnO. The uniformity in size and nearly spherical shape of ZnO
nanoparticles, forming various forms of agglomerates, were observed. Compared to
both, the unmodified and commercial ZnO, all the prepared Ag/ZnO composites
showed a broad band in the visible region at 500 nm, resulting in a narrowing of the
band gap. This band confirms the surface plasmon resonance of the metallic Ag
nanoparticles, since they can absorb visible light and activate the photocatalyst in
the visible spectrum.
All the obtained nanopowders showed higher adsorption power and
photocatalytic activity in the degradation of RO16 dye than the commercial ZnO.
The powder with 1.5 mol% of Ag had the highest photocatalytic efficiency as a
consequence of smaller Ag particles and their good distribution, as well as the
narrowest band gap. This means that the photocatalytic activity does not depend on
the Ag content only and that the size and distribution of the metal particles play an
important role. Since the ZnO with 1.5 mol% of Ag demonstrated the best
photocatalytic activity, the same sample was tested for diverse dyes and the high
photocatalytic efficiency was also confirmed by testing on AG25, MB9 and EV
dyes.

AB  - In this work, in order to improve the photocatalytic efficiency of ZnO, the optimal CeO2 content in ZnO powders was determined by varying the quantity of CeO2 from 0 to 10 mol%. The structural, microstructural, optical, textural, and photocatalytic properties of the hydrothermally obtained ZnO and CeO2/ZnO nanocomposites have been investigated by using the XRPD, FESEM, HRTEM/SAED, BET, and UV–Vis techniques. Detailed characterization revealed that CeO2, having spherical nanodots of about 5 nm with a large surface area, was distributed onto the ZnO surface, whose crystallites displayed a bimodal distribution, from nano-to micro-crystals. The morphology of ZnO is a combination of nanograins and microrods that further makes a 3-D tie-like morphology. The nanocomposite containing 5 mol% of CeO2 showed about 30% better photocatalytic efficiency in the degradation of Reactive Orange 16 dye compared to other samples under simulated solar radiation. In addition, the kinetics and mechanism of photocatalytic degradation were also proposed based on the photocatalytic activity and scavenger tests.

AB  - In recent years, thermal decomposition studies of transition metal complexes with benzenepolycarboxylate ligands have become an area of a great importance due to the possibility of obtaining useful metal oxides with desirable electrical, magnetic and catalytic properties [1]. As a
contrast to conventional methods for the preparation of metal oxides, such as hydrothermal or sol–
gel treatment, thermolysis is faster, more efficient and environmentally friendly. Mn(II)–dipya
(dipya = 2,2’-dipyridylamine) complex with tetraanion of 1,2,4,5-benzenetetracarboxylic
(pyromellitic, H4pyr) acid, [Mn2(dipya)2(pyr)(H2O)2], has been prepared and characterized by
elemental, spectral and microscopy analyses. Direct thermolysis of the complex up to 1200 °C in an air atmosphere yielded spinel Mn3O4 oxide material. The obtained Mn3O4 has been characterized for its structural, spectroscopic, morphological and optical properties. The possibilities of using this oxide as photocatalyst or co-photocatalyst for removing textile organic dyes, as well as inorganic pigmentary material, were also investigated and discussed.

AB  - Regarding enormous expansion of bacterial contamination as well as their increase resistivity to commonly used disinfectants, there is a great demand for antibacterial material, which will not be based on organic compounds. Among various inorganic substances, environmentally friendly, low-cost and chemically stable ZnO and TiO2 demonstrate considerable antibacterial activity.
This work primarily focuses on idea of developing novel disinfectant based on both, ZnO and TiO2, which would integrate all the worthy properties of both oxides. For that matter, titanium(IV) butoxide was dissolved in a solution of zinc acetate following with the ammonia addition until pH value was 8.5. Half of the initial solution was hydrothermally treated, dried and calcined at 500 (H-ZnTi-500) and 800°C (H-ZnTi-800). Two other samples (ZnTi-500 and ZnTi-800) were obtained from the other half of the initial solution which was directly dried and calcined under the same conditions. The samples were characterized by XRD including Rietveld refinement, FESEM
and TG/DTA. Antibacterial activity was examined towards Gram-positive S. aureus and Gram-negative E. coli .
The results showed that only ZnTi-800 consisted of pure Zn2TiO4 (Fd-3m) while Zn TiO was the major phase in three other samples. In the case of samples calcined at 500 °C, traces of ZnO were found. H-ZnTi-800 contained three phases: Zn2TiO4, ZnO and Zn2Ti3O8 (P4332). Cubic Zn2TiO4 contains two cation sites: tetrahedrally coordinated Zn at 0,0,0 and octahedral site at 5/8,5/8,5/8 shared between Zn and Ti. The calculated a-parameters of all obtained Zn2TiO4 as well as Zn–O and Zn/Ti–O bond distances were independent of synthesis. At 500 °C nanocrystalline Zn2TiO4 were obtained with the crystallite sizes 26 and 71 nm for H-ZnTi-500 and ZnTi-500, respectively, while microcrystalline phases were obtained at 800 °C with the crystallite sizes larger than 110 nm. The soft agglomerates consisted of smaller particles were obtained at 500 °C comparing to samples at 800 °C having more compact agglomerates.
The best antibacterial activity with high reduction in the number of bacteria cells (87.6 % of E. coli and 63.4 % of S. aureus) was exhibited by the ZnTi-500. It means that the purity of samples, crystallite size and softness of agglomerates, influence antibacterial activity and that optimal level of all factors should be reached since ZnTi-500 was almost pure with sufficiently small crystallites and soft agglomerates.

AB  - Zinc oxide nanoparticles (ZnO-NPs) have been a subject of numerous researches owing to their multifunctional properties in many applications, such as solar cells, UV light-emitting devices, gas sensors and photocatalysts. ZnO-NPs can be synthesized through various methods and their features can be tailored by shape and size, resulting in new applications relevant to their structural properties.
	The synthesis of ZnO-NPs via controlled thermal decomposition of the single-source precursors represents a novel synthetic methodology. The basic goal of this study was to investigate the influence of precursors on crystallite size and morphology of the resulting ZnO-NPs. Four structurally characterized Zn complexes with different benzenepolycarboxylato ligands [1] were used as precursors for investigation of photocatalytic and antimicrobial effects of thermally obtained ZnO-NPs.
	The XRPD and FESEM analysis of ZnO-NPs, prepared by thermolysis of Zn precursors at 450 °C in the air atmosphere, revealed hexagonal wurtzite structure (space group P63mc, a ≈ 3.25 and c ≈ 5.21 Å) with an average crystallite size in the range of 39–47 nm and similar morphology. The best photocatalytic activity for degradation of Reactive orange 16 dye has been observed for ZnO-NPs where crystallites form the smallest agglomerates. All obtained ZnO-NPs showed excellent inhibitory effect against Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Escherichia coli.

AB  - Kontaminacija bakterijama je poslednjih godina postala problem na globalnom nivou zbog
čega se javila potreba za novim antibakterijskim agensima. Stabilni titan-
-dioksid i cink-oksid pokazuju antibakterijsku aktivnost te se smatraju pogodnim
materijalima i zbog njihove netoksičnosti i niske cene [1, 2].
Cilj ovog rada bio je dobijanje novog materijala na bazi ZnO i TiO2 sa
antibakterijskim svojstvima. U tu svrhu, titan(IV)-butoksid (25 mol.%) rastvoren je u vodenom
rastvoru cink-acetata (75 mol.%), nakon čega je dodavan amonijak dok
vrednost pH nije iznosila 8,5. Polovina dobijenog rastvora je hidrotermalno tretirana
12 h na 120 °C, zatim sušena 20 h na 100 °C i kalcinisana 1 h na 500 (uzorak H-ZnTi-500) i
800 °C (uzorak H-ZnTi-800). Druga polovina dobijenog rastvora bila je direktno sušena i
kalcinisana pod istim uslovima (uzorci ZnTi-500 i ZnTi-800).
Na osnovu XRD rezultata, fazni sastav i veličina kristalita izračunati su u Powder Cell programu,
dok su parametri jedinične ćelije i dužine veza dobijeni Ritveldovim utačnjavanjem
pomoću FullProf/Winplotr programskog paketa. Termogravimetrijskom analizom nekalcinisanih
uzoraka određena je temperatura kalcinacije. Antibakterijska aktivnost dobijenih prahova ispitana
je prema dva soja bakterija: Gram-pozitivnoj S. aureus ATCC 25923 i Gram-negativnoj E. coli
DSM 498.
Jednofazni kubni Zn2TiO4 (ICSD#162392, prostorna grupa ) dobijen je jedino u slučaju
ZnTi-800, dok je u ostale tri sinteze Zn2TiO4 bio većinska faza. Pored Zn2TiO4, uzorci
H-ZnTi-500 i ZnTi-500 sadržali su 22 i 4 mas.% ZnO (ICSD#26170) redno, dok je u uzorku
H-ZnTi-800 pronađeno 7 mas.% ZnO i 5 mas.% Zn2Ti3O8 (ICSD#083525). Parametar a svih dobijenih
Zn2TiO4 pokazao se nezavisnim od samog procesa sinteze, a dobijene vrednosti su približno
iste: 8,4465(3) za H-ZnTi-500, 8,4604(2) za ZnTi-500, 8,4564(2) za H-ZnTi-800 i 8,4565(2) Å za
ZnTi-800. U strukturi kubnog Zn2TiO4 postoje dva katjonska mesta: tetraedarski koordinirani Zn u
0,0,0, i oktaedarski koordinirani Zn i Ti koji dele položaj 5/8,5/8,5/8. Dužine veza Zn–O i Zn/Ti–
O su takođe nezavisne od uslova sinteze. Na 500 °C dobijeni su nanokristalni Zn2TiO4 (veličina
kristalita iznosila je 26 i 71 nm za H-ZnTi-500 i ZnTi-500, respektivno) dok su mikrokristalni
Zn2TiO4 nastali na 800 °C (veličina kristalita prelazila je 110 nm). Od svih uzoraka, ZnTi-500 je
pokazao najbolju antibakterijsku aktivnost dostignuvši visoki stepen redukcije broja bakterijskih
kolonija: 87,6 % E. coli DSM 498 i 63,4 % S. aureus ATCC 25923. To se može pripisati činjenici
da je u ovom slučaju dobijen gotovo jednofazni Zn2TiO4 sa dovoljno malom veličinom kristalita.

AB  - In recent years bacterial contamination has become a significant problem of the global environment
causing the necessity for novel antibacterial agents. Stable,
non-toxic and low cost zinc oxide and titanium dioxide are considered as suitable
antibacterial materials [1, 2].
The aim of this work was to find a new antibacterial material based on both, ZnO and TiO2.
Therefore, titanium(IV) butoxide (25 mole%) was dissolved in a water solution of zinc acetate (75
mole%) after which the ammonia was added until pH was adjusted to 8.5. Half of the obtained
solution was hydrothermally treated for 12 h at 120 °C, dried for 20 h at 100 °C and then calcined
at 500 (sample H-ZnTi-500) and 800 °C (sample H-ZnTi-800) for 1 h. The other half of obtained
solution was directly dried and calcined under the same conditions (samples ZnTi-500 and
ZnTi-800).
Base on XRD data for obtained powders, the phase composition and crystallite size were calculated
in Powder Cell software while unit cell parameters and bond distances were obtained by
Rietveld refinement using FullProf software in Winplotr environment. TG analysis of uncalcined
samples was used to determine temperature of calcination. Antibacterial properties of obtained
powders were examined towards Gram-positive S. aureus ATCC 25923 and Gram-negative E. coli
DSM 498 bacteria.
The single-phase cubic Zn2TiO4 phase (ICSD#162392, space group ) was
obtained in the case of ZnTi-800 while, for three other samples, the Zn2TiO4 is found to be a predominant
phase. Beside Zn2TiO4 samples H-ZnTi-500 and ZnTi-500 contained 22 and 4 wt.% of
ZnO (ICSD#26170) respectively, while H-ZnTi-800 had 7 wt.% of ZnO and 5 wt.% of Zn2Ti3O8
(ICSD#083525). The a-parameter of all obtained Zn2TiO4 was independent of synthetic procedure
having following values: 8.4465(3) for H-ZnTi-500, 8.4604(2) for ZnTi-500, 8.4564(2) for
H-ZnTi-800 and 8.4565(2) Å for ZnTi-800. Two cation sites can be found in cubic Zn2TiO4: tetrahedrally
coordinated Zn at 0,0,0 and octahedral site at 5/8,5/8,5/8 shared between Zn and Ti. The
Zn–O and Zn/Ti–O bond distances were also independent of synthesis. The nanocrystalline
Zn2TiO4 phases were obtained at 500 °C (crystallite size for H-ZnTi-500 and ZnTi-500 were 26
and 71 nm respectively), and microcrystalline ones at 800 °C (the crystallite size exceeded 110
nm). Among all samples, the ZnTi-500 demonstrated the best antibacterial activity reaching high
reduction in the number of bacteria cells: 87.6 % of E. coli DSM 498 and 63.4 % of S. aureus
ATCC 25923. This could be explained by the fact that almost pure Zn2TiO4 phase was obtained
with sufficiently small crystallites.

abstract = "Kontaminacija bakterijama je poslednjih godina postala problem na globalnom nivou zbog
čega se javila potreba za novim antibakterijskim agensima. Stabilni titan-
-dioksid i cink-oksid pokazuju antibakterijsku aktivnost te se smatraju pogodnim
materijalima i zbog njihove netoksičnosti i niske cene [1, 2].
Cilj ovog rada bio je dobijanje novog materijala na bazi ZnO i TiO2 sa
antibakterijskim svojstvima. U tu svrhu, titan(IV)-butoksid (25 mol.%) rastvoren je u vodenom
rastvoru cink-acetata (75 mol.%), nakon čega je dodavan amonijak dok
vrednost pH nije iznosila 8,5. Polovina dobijenog rastvora je hidrotermalno tretirana
12 h na 120 °C, zatim sušena 20 h na 100 °C i kalcinisana 1 h na 500 (uzorak H-ZnTi-500) i
800 °C (uzorak H-ZnTi-800). Druga polovina dobijenog rastvora bila je direktno sušena i
kalcinisana pod istim uslovima (uzorci ZnTi-500 i ZnTi-800).
Na osnovu XRD rezultata, fazni sastav i veličina kristalita izračunati su u Powder Cell programu,
dok su parametri jedinične ćelije i dužine veza dobijeni Ritveldovim utačnjavanjem
pomoću FullProf/Winplotr programskog paketa. Termogravimetrijskom analizom nekalcinisanih
uzoraka određena je temperatura kalcinacije. Antibakterijska aktivnost dobijenih prahova ispitana
je prema dva soja bakterija: Gram-pozitivnoj S. aureus ATCC 25923 i Gram-negativnoj E. coli
DSM 498.
Jednofazni kubni Zn2TiO4 (ICSD#162392, prostorna grupa ) dobijen je jedino u slučaju
ZnTi-800, dok je u ostale tri sinteze Zn2TiO4 bio većinska faza. Pored Zn2TiO4, uzorci
H-ZnTi-500 i ZnTi-500 sadržali su 22 i 4 mas.% ZnO (ICSD#26170) redno, dok je u uzorku
H-ZnTi-800 pronađeno 7 mas.% ZnO i 5 mas.% Zn2Ti3O8 (ICSD#083525). Parametar a svih dobijenih
Zn2TiO4 pokazao se nezavisnim od samog procesa sinteze, a dobijene vrednosti su približno
iste: 8,4465(3) za H-ZnTi-500, 8,4604(2) za ZnTi-500, 8,4564(2) za H-ZnTi-800 i 8,4565(2) Å za
ZnTi-800. U strukturi kubnog Zn2TiO4 postoje dva katjonska mesta: tetraedarski koordinirani Zn u
0,0,0, i oktaedarski koordinirani Zn i Ti koji dele položaj 5/8,5/8,5/8. Dužine veza Zn–O i Zn/Ti–
O su takođe nezavisne od uslova sinteze. Na 500 °C dobijeni su nanokristalni Zn2TiO4 (veličina
kristalita iznosila je 26 i 71 nm za H-ZnTi-500 i ZnTi-500, respektivno) dok su mikrokristalni
Zn2TiO4 nastali na 800 °C (veličina kristalita prelazila je 110 nm). Od svih uzoraka, ZnTi-500 je
pokazao najbolju antibakterijsku aktivnost dostignuvši visoki stepen redukcije broja bakterijskih
kolonija: 87,6 % E. coli DSM 498 i 63,4 % S. aureus ATCC 25923. To se može pripisati činjenici
da je u ovom slučaju dobijen gotovo jednofazni Zn2TiO4 sa dovoljno malom veličinom kristalita.

[2] T. Matsunaga et al., FEMS Microbiology Letters, 29 (1985) 211–214., In recent years bacterial contamination has become a significant problem of the global environment
causing the necessity for novel antibacterial agents. Stable,
non-toxic and low cost zinc oxide and titanium dioxide are considered as suitable
antibacterial materials [1, 2].
The aim of this work was to find a new antibacterial material based on both, ZnO and TiO2.
Therefore, titanium(IV) butoxide (25 mole%) was dissolved in a water solution of zinc acetate (75
mole%) after which the ammonia was added until pH was adjusted to 8.5. Half of the obtained
solution was hydrothermally treated for 12 h at 120 °C, dried for 20 h at 100 °C and then calcined
at 500 (sample H-ZnTi-500) and 800 °C (sample H-ZnTi-800) for 1 h. The other half of obtained
solution was directly dried and calcined under the same conditions (samples ZnTi-500 and
ZnTi-800).
Base on XRD data for obtained powders, the phase composition and crystallite size were calculated
in Powder Cell software while unit cell parameters and bond distances were obtained by
Rietveld refinement using FullProf software in Winplotr environment. TG analysis of uncalcined
samples was used to determine temperature of calcination. Antibacterial properties of obtained
powders were examined towards Gram-positive S. aureus ATCC 25923 and Gram-negative E. coli
DSM 498 bacteria.
The single-phase cubic Zn2TiO4 phase (ICSD#162392, space group ) was
obtained in the case of ZnTi-800 while, for three other samples, the Zn2TiO4 is found to be a predominant
phase. Beside Zn2TiO4 samples H-ZnTi-500 and ZnTi-500 contained 22 and 4 wt.% of
ZnO (ICSD#26170) respectively, while H-ZnTi-800 had 7 wt.% of ZnO and 5 wt.% of Zn2Ti3O8
(ICSD#083525). The a-parameter of all obtained Zn2TiO4 was independent of synthetic procedure
having following values: 8.4465(3) for H-ZnTi-500, 8.4604(2) for ZnTi-500, 8.4564(2) for
H-ZnTi-800 and 8.4565(2) Å for ZnTi-800. Two cation sites can be found in cubic Zn2TiO4: tetrahedrally
coordinated Zn at 0,0,0 and octahedral site at 5/8,5/8,5/8 shared between Zn and Ti. The
Zn–O and Zn/Ti–O bond distances were also independent of synthesis. The nanocrystalline
Zn2TiO4 phases were obtained at 500 °C (crystallite size for H-ZnTi-500 and ZnTi-500 were 26
and 71 nm respectively), and microcrystalline ones at 800 °C (the crystallite size exceeded 110
nm). Among all samples, the ZnTi-500 demonstrated the best antibacterial activity reaching high
reduction in the number of bacteria cells: 87.6 % of E. coli DSM 498 and 63.4 % of S. aureus
ATCC 25923. This could be explained by the fact that almost pure Zn2TiO4 phase was obtained
with sufficiently small crystallites.

AB  - Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc-benzenepolycarboxylato complexes as single-sourceprecursors at 450 degrees C in an air atmosphere. The mechanism and kinetics of thermal degradation of zinc-benzenepolycarboxylato complexes were analyzed under non-isothermal conditions in an air atmosphere. The results of X-ray powder diffraction and field emission scanning electron microscopy revealed hexagonal wurtzite structure of ZnO with an average crystallite size in the range of 39-47 nm and similar morphology. The band gap and the specific surface area of ZnO nanoparticles were determined using UV-Vis diffuse reflectance spectroscopy and the Brunauer, Emmett and Teller method, respectively. The photoluminescent, photocatalytic and antimicrobial properties of the ZnO nanoparticles were also examined. The best photocatalytic activity in the degradation of C. I. Reactive Orange 16 dye was observed for the ZnO powder where the crystallites form the smallest agglomerates. All ZnO nanoparticles showed excellent inhibitory effect against Gram-positive bacterium Staphylococcus aureus and Gram-negative bacterium Escherichia coli.

AB  - We report a mesoporous composite system consisting of carbon fiber cores surrounded with Co1.5Mn1.5O4 spinel nanocrystal shells, synthesized by a simple two-step process involving single-nozzle co-electrospinning and subsequent calcination. Benefiting from the obtained core-shell structure, this composite has exhibited high specific capacitance in the two-electrode configuration, up to 384 F g(-1) at 0.28 A g(-1), with no capacitance loss after 2000 cycles at 50 mV s(-1). The incorporation of spinel nanocrystals improved the capacitive performances of composite fibers due to a synergistic effect of redox-active shells and the conductive cores, making this novel material promising for symmetrical supercapacitors.
