Summary: Silica-coated titanium nitride (TiN/SiO2) particles were synthesized using a sol-gel method and the hardness of the sintered bodies fabricated with these particles was evaluated. The presence of few micropores in the TiN/SiO2 structure resulted in particles with small specific surface areas. The Vickers hardness increased in the order: TiN < TiN-SiO2 < TiN/SiO2A < TiN/SiO2S. The SiO2 shell acted as a sintering aid and the NaOH catalyst improved the density and hardness of the sintered body.

Summary: The study investigates the thermo-reversible sol-gel transition in solutions made of titanium n-butoxide, ethanol, water, and nitric acid using in situ temperature-dependent Fourier transform infrared spectroscopy. It was found that the nitrate ion plays a key role in substituting ligands and forming bridges and chelates, leading to gel formation. The elastic component was identified as the most important in the material's structure based on dynamic rheological studies of the temperature-dependent viscoelastic behavior.

Summary: In this study, core/shell ZnO/TiO2 nanocomposite samples were prepared using the sol-gel method at different time spans. The sample prepared in the 15-minute time span (ZnTi15) exhibited the highest photocatalytic activity and charge carrier density, making it the optimal sample. The formation of a heterojunction at the ZnO/TiO2 interface could be attributed to the increased photocurrent density observed for the ZnTi15 sample.

Doping with Cr and Cr/N enhances adsorption capacity and photocatalytic performance, with Cr-TiO2 nanoparticles exhibiting antibacterial activity under visible light. The differences in electrostatic charge and nanoparticle dispersion are suggested as the main reasons for the varied antibacterial response among the doped nanoparticles.

Summary: The combination of lithographic methods and sol gel bottom-up techniques shows promising potential for nanopatterning substrates. In this study, ordered mesoporous silica was successfully deposited into nanopatterned silica substrates using dip coating. The effect of sol composition on pore ordering was probed, and the pH controlled the transformation from circular to columnar mesophase. The deposition of vertical mesopores with good repeatability was demonstrated, and the effect of sol chemistry on surfactant curvature was found to be similar in nanopatterned substrates made by e-beam lithography.

Summary: In this work, we synthesized original LDH nanocarriers that can strictly host antibiotics and be used for antimicrobial purpose. The total antibiotic intercalation within the nanocarriers was confirmed by infrared and XRD analyses. We demonstrated that LDH exhibited purely bacteriostatic activity in the absence of biocides, and an additive effect was observed when antibiotics were hosted and released from these nanocarriers. The use of LDH as nanocarriers for antimicrobial agents delivery is of great interest due to the possibility of recycling and reloading with antimicrobial agents after total release.

Summary: Li3N is an excellent protective coating materialforlithium electrodes. The formation of stable and homogeneouscoatings is technically challenging. In this study, we found that protective Li(3)N coatings can be simply formed by the direct reaction of electrodeposited lithium electrodes with N-2 gas. However, using battery-grade lithium foil is problematic due to the presence of a native passivation layer.

It was found that the catalytic performance decreased with the introduction of tungsten. Furthermore, substitution with tungsten did not have a significant effect on lattice nitrogen reactivity, but resulted in a loss of lattice nitrogen in Co3Mo2.6W0.4N and Ni2Mo3N.

Summary: A self-standing three-dimensional TiC-modified carbon fibre network is fabricated via carbothermal reduction, which provides a solution for the problems of Li dendrite formation, large volume expansion, and unstable solid electrolyte interface films in lithium metal batteries. The lithiophilic TiC promotes homogeneous and rapid Li deposition, while the 3D conductive structures with high surface area reduce local current density and accommodate volume changes. The TiC@C electrode shows a nearly zero Li nucleation overpotential and low voltage hysteresis, achieving a coulombic efficiency of 99.6% over 200 cycles and an impressive capacity retention of 87% over 250 cycles in full cells with LiFePO4 cathode.

Summary: The production of vertically oriented mesoporous silica films has been a challenge since the 1990s. The electrochemically assisted surfactant assembly (EASA) method using cationic surfactants has been successful in achieving the desired vertical orientation. The synthesis of porous silicas using surfactants with increasing head sizes has been explored, showing that while the larger head groups increase pore size, they also reduce the degree of hexagonal order in the vertically aligned pores and pore accessibility.

Summary: In this study, WS2xSe2-2x (0 <= x <= 1) binary and ternary thin films were successfully deposited using single source precursors [WECl4(E'Bu-n(2))] (E = S or Se; E' = S or Se) through low-pressure chemical vapour deposition. The deposits were characterized by grazing-incidence X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy, confirming their phase purity and stoichiometry. Hall measurements revealed high electrical conductivities for the films, which can be tuned through an annealing process by manipulating Se and S vacancies. The thermoelectric capabilities of the WS2xSe2-2x films were evaluated using variable-temperature Seebeck measurements, showing a peak power factor of 6 mu W m(-1) K-2 for the as-deposited WS2 film at 553 K.

Summary: Silica thin films with vertical nanopores are used to control access to electrode surfaces and as templates for nanomaterial growth. The electrochemically assisted surfactant assembly method, which is the most effective way to produce these films, also results in aggregates of silica particles. This study demonstrates that applying an AC signal to the potential during growth prevents the formation of aggregates, resulting in only a few single particles. This finding is attributed to better control of the diffusion field of hydroxide ions responsible for particle growth. The resulting films are smooth and have highly ordered hexagonal pore structures.
