Summary: Zn and N codoped TiO2 thin films were grown using chemical vapor deposition, with different concentrations of Zn impacting superoxide formation, photocatalytic activity, and bactericidal properties. The 0.4% Zn,N:TiO2 thin film demonstrated the highest formal quantum efficiency in degrading stearic acid, while the 1.0% Zn,N:TiO2 film showed the highest bactericidal activity under both UVA and fluorescent light conditions. The enhanced efficiency of the films was correlated with increased charge carrier lifetime, supported by transient absorption spectroscopy measurements.

Summary: This study investigates the photocatalytic and photoinduced hydrophilic properties of pure and nitrogen doped TiO2-W5O14 nanocomposite thin films. The results are compared with reactively sputtered nanocrystalline titanium dioxide (TiO2) and nanowire tungsten oxide (W18O49) thin films. The TiO2-W5O14 thin films show high crystallinity and multiphase structures, while the TiO2 and W18O49 thin films have anatase and monoclinic structures, respectively. The nitrogen doped TiO2-W5O14 nanocomposite thin films exhibit better photohydrophilicity and photocatalytic efficiency due to bandgap shift, porous surface structures, and crystallinity.

The obtained NT electrodes have a large electrochemically active surface and outperform the efficiency of equivalent planar-layered electrodes by more than one order of magnitude. The characteristics of the WO3/BiVO4 Schottky barrier heterojunction control the NT electrode efficiency, which depends on the BiVO4 outer layer thickness and the incorporation of the CoPi electrocatalyst, as demonstrated by thorough electrochemical analysis.

Summary: The formation of monoclinic VO2 crystal domains at low temperatures in nanocolumnar vanadium/oxygen thin films deposited via magnetron sputtering is analyzed. The synthesis involved depositing amorphous nanocolumnar VO1.9 thin films at room temperature and annealing them at temperatures between 250 - 330 ? in an oxygen atmosphere. The nanocolumnar structures exhibited a thermochromic transition at 47 ? (for annealing at 270 ?) and 58 ? (for annealing at 280 and 290 ?), resulting in a significant drop in optical transmittance in the infrared region.

Summary: This paper studied the morphology and void connectivity of thin films grown by magnetron sputtering deposition at oblique geometries. A well-tested thin film growth model was used, along with experimental data, to assess the features of these layers. The film morphology and pore topology varied significantly with the growth conditions, which were linked to the different collisional transport of sputtered species in the plasma gas. Four different film morphologies were identified, and their porous network characteristics were described, explaining their potential applications in electrochromic sensors or infiltration with nanoparticles.

Summary: In this study, a novel methodology of plasma-assisted thin film structuration was proposed by combining piezoelectric AWs and plasmas during the growth of a thin film. SiO2 and SiOx (x<2) thin films were deposited by magnetron sputtering at oblique angles (MS-OAD) on an electro-acoustically excited LiNbO3 piezoelectric substrate under resonant conditions. The resulting films exhibited 2D patterned microstructure with submillimeter size intermingled zones, which replicated the distribution of polarization potential on the AW activated substrate immersed in the plasma. The main mechanism responsible for the appearance of domains with different morphology and chemical composition was found to be the focused impingement of Ar+ plasma ions on certain regions of the substrate. The discussed the general character of this patterning process, the underlying physics, and its possibilities to tailor the composition and microstructure of dielectric thin film materials.

Summary: In this study, we have developed a method using lower laser irradiation conditions to generate aluminum surfaces with dual-scale roughness, resulting in double or even triple the Sp parameter values compared to reference samples. This was achieved by coating aluminum substrates with a highly transparent aluminum oxynitride capping layer. The resulting surfaces, consisting of partially oxidized aluminum with negligible amounts of nitrogen species, exhibited high hydrophobicity and showed long icing delay times for anti-icing applications. A correlation was found between the wetting and anti-icing behaviors, the use of a capping layer, and the laser irradiation conditions.

Summary: Carbon nanodots (CNDs) are used as fluorescent nanosensitizers to enhance the photocatalytic response of semiconductors beyond the ultraviolet range. The addition of nitrogen heteroatoms to the carbogenic network of CNDs improves their photostability and optical properties. Laser pyrolysis is a versatile technique for synthesizing N-doped CNDs by using a liquid solvent containing nitrogen as the carbon precursor. These N-doped CNDs exhibit enhanced photoactivity when combined with P25 nanoparticles for the conversion of methyl orange under white LED illumination, generating various reactive oxygen species.
