AB  - The efficiency of titanate-nanotubes-based photocatalysts towards hydrogen production was studied in the presence of the sacrificial agent, 2-propanol. The highest hydrogen production rate (~120 lmol h 1 g 1 ) was observed over surface-modified titanate nanotubes by 5-amino salicylic acid decorated with nanometer-sized silver nanoparticles. The X-ray diffraction analysis, transmission electron microscopy, nitrogen adsorption–desorption isotherms, and diffuse reflection spectroscopy were applied to characterize the prepared photocatalytic materials. The better photocatalytic performance of inorganic–organic hybrid materials in comparison to the pristine titanate nanotubes is a consequence of their improved light-harvesting ability due to the formation of interfacial charge transfer (ICT) complex, as well as the presence of metallic silver nanoparticles that suppress the recombination of photo-generated charge carriers. The spin trapping EPR experiments under irradiation of prepared photocatalysts with either UV or visible light were used to monitor the appearance of hydroxyl radicals and superoxide radical anions. The generation of superoxide radical anions under visible light irradiation was detected for hybrid materials, but not for the pristine titanate nanotubes. These results are a consequence of enhanced promotion ofelectrons to the conduction band due to extended absorption in visible spectral range in hybrids and support the higher efficiency of hydrogen generation observed for surface-modified titanate nanotubes by 5-amino salicylic acid decorated with silver nanoparticles.

AB  - Nickel−cobalt (Ni−Co) alloy powders were produced galvanostatically by using sulphate electrolytes with
various ratios of Ni2+/Co2+ (mole ratios). The morphology, phase structure, chemical composition and magnetic
properties were examined by scanning electron microscope (SEM), X-ray diffractometer (XRD), atomic emission
spectrometer (AES), and SQUID-based magnetometer, respectively. Morphology of the particles changed from
cauliflower-like and dendritic to coral-like and spongy-like ones with increasing Ni2+/Co2+ ratio from 0.25 to 4.0. XRD
analysis of the Ni−Co powders revealed that the decrease of Ni2+/Co2+ ratios (the increase of Co content) caused a
change of structure from face centered cubic (FCC) obtained for the ratios of 4.0, 1.5 and 0.67 to a mixture of FCC and
hexagonal closed-packed (HCP) phases for the ratio of 0.25. The increasing content of nickel led to change of
mechanism of electrolysis from irregular (up to ~40 wt.% Ni in the electrolytes) to close to equilibrium (between
~40 and 60 wt.% Ni in the electrolytes) and anomalous co-deposition (over 60 wt.% Ni in the electrolytes) type. All of
the obtained Ni−Co alloy samples behaved as soft magnetic materials while their magnetic parameters showed
immediate composition dependence since both coercivity and saturation magnetization almost linearly increased with
increase of the Co content.

AB  - Combining the electrical, optical, and magnetic properties of polyaniline (PANI) with
excellent chemical and physical properties of gold nanoparticles (Au NPs) is an efficient
way to create novel functional nanomaterials with potential applications in biosensing and
therapy, energy conversion and storage. In the present work, we report polyaniline/gold
nanocomposite (PANI/Au) obtained by two-phase, water/toluene, interfacial chemical
reaction. The polymerization process occurs at the interface of the organic phase (with
aniline) and acidic water solution (with oxidant and Au NPs). Using this strategy, secondary
growth of PANI could be suppressed. Transmission and scanning electron microscopy
measurements were confirmed that PANI was formed as nanofibers decorated with 17 nm
Au NPs. Characterization of the samples performed with UV-Vis and FTIR spectroscopy
and XRD technique are used for description of the optical properties, interaction between
components and structure of PANI/Au system. The obtained results indicate that the
present synthetic route produces the PANI in conductive form (doped emeraldine salt
form) with specific electric behavior, which makes PANI/Au nanocomposite suitable
material for a wide range of applications.

AB  - The morphology, phase and chemical composition of Ni-Co alloy powders electrodeposited from an ammonium sulfate-boric acid containing electrolyte with different ratio of Ni/Co ions were investigated. The ratios of NVCo ions were 1/1, 1/2 and 1/3. The morphology, chemical composition and phase composition of the electrodeposited alloy powders were investigated using AES, SEM, EDS and XRD analysis. Composition of the electrolyte, i.e. the ratio of Ni/Co concentrations was found to influence both, the alloy phase composition and the morphology of Ni-Co alloy powders. At the highest ratio of Ni/Co = 1/1 concentrations typical 2D fern-like dendritic particles were obtained. With a decrease of NVCo ions ratio among 2D fern-like dendrites, 3D dendrites and different agglomerates were obtained. X-ray diffraction studies showed that the alloy powders mainly consisted of the face-centered cubic alpha-nickel phase and hexagonal close-packed alpha-cobalt phase and minor proportions of face-centered cubic alpha-cobalt phase. The occurrence of the latter phase was observed only in the alloy powder with the higher cobalt concentration in electrolyte. The electrodeposition of Ni-Co powders occurred in an anomalous manner.

The crystal structures of both doped samples are refined and described in this article. The results of Rietveld refinements clearly indicate that Yb3+ ions are incorporated into the hexacelsians structure. AFM photomicrographs show round-shaped particles with the size of few microns. The magnetization measurements were done within the 2-300 K temperature range, revealing an enhancement of magnetization with temperature that is not in accordance with simple paramagnetic behavior.
