Summary: Three-layer structured composite films consisting of a rutile titanium dioxide (TiO2) film, a cuprous oxide (Cu2O) nanofilm, and silver (Ag) particles were prepared through sputtering and annealing. The Ag particle/Cu2O/TiO2 composite films exhibited superior photoelectrochemical and photocatalytic properties due to the plasmon resonance of Ag particles and the effective electron traps provided by the Ag particles on the Cu2O nanolayer. The suitable Ag particle content was found to be an important factor affecting the photoactive performance of the composite film.

Summary: The quality of the dielectric/organic semiconductor interface plays a crucial role in determining the charge transport properties in organic thin-film transistors (OTFTs). A study introduced a method of capping the surface of Hf and Zr hybrid dielectrics with an ultra-thin pV3D3 layer to improve the dielectric/semiconductor interface and enhance VT stability, resulting in higher mobility and improved charge transport properties in p-type OTFTs. This combined approach shows potential in overcoming limitations and improving overall device performance in OTFTs.

Summary: In this study, a phase engineering strategy was explored to improve the electrochemical performance of transition metal sulfides (TMSs) as anode materials for lithium-ion batteries (LIBs). MoS2 nanostructures were synthesized using a one-pot hydrothermal approach. By simple calcination in the temperature range of 200-300 degrees C, MoS2 and MoO3 phases can be readily controlled. The optimized MoO3@MoS2 hybrid exhibited enhanced performance compared to pristine MoS2 and MoO3, attributed to the formation of a MoO3 passivation layer and reactive interfaces between the two phases.

Summary: V- and W-containing oxide-phosphate layers were formed on titanium through plasma electrolytic oxidation. The replacement of vanadate with tungstate was studied to understand its effect on voltage-time responses, surface morphology, composition, optical and photocatalytic properties. The incorporation of V and W into the coatings was mainly attributed to thermolysis of vanadungstophosphate hetero-polyoxoanions, while high concentrations of polyphosphate species contributed to the amorphization of coatings and the formation of a titanium phosphate matrix. The formed coatings showed photocatalytic activity in the degradation of methyl orange.

Summary: We developed a simple method to construct a supramolecular glycomaterial for targeted delivery of antibiotics to P. aeruginosa in a photothermally-controlled manner. The galactose-pyrene conjugate (Gal-pyr) self-assembled with graphene nanoribbon-based nanowires via pi-pi stacking to produce a supramolecular glycomaterial, which exhibited significantly enhanced binding avidity toward a galactose-selective lectin compared to Gal-pyr alone. The as-prepared glycomaterial eradicated P. aeruginosa-derived biofilms under near-infrared light irradiation by accelerating antibiotic release due to the strong photothermal effect of the nanowires.

Summary: Inactivation of bioaerosols is crucial in preventing the spread of microbial pathogens in the air. Traditional photocatalytic inactivation processes are time-consuming and generate insufficient reactive oxygen species (ROSs) to irreversibly inactivate bacteria. A new photocatalytic ozonation (PCO) system was developed in this study, utilizing NiFeOOH nanosheets on nickel foam and trace concentration of ozone. The PCO system demonstrated a remarkable inactivation efficiency of 99.99% within a short retention time of 8.07 s, with no bacteria surviving after 24 h cultivation. This novel PCO system offers a more efficient method for bioaerosol inactivation and reduces the risk of exposure.

Summary: Exploring the interactions among doping heteroatom, carbon and metal atoms can significantly enhance the catalytic performance and gain an insightful understanding of the heterogeneous catalysis mechanism. The N,P co-doped carbon-coated cobalt (Co@NPC) catalyst exhibits high selectivity and water-durability in aqueous-phase hydrogenation of cinnamaldehyde, with precise control of products by adjusting N and P doping. The synergy of geometry and electrons in Co@NPC di-heteroatoms allows for selective reduction of C=O, while Co@NC without P doping shows high activity but significant productivity of saturated alcohols under equivalent conditions. The electronegativity difference among N, C and P atoms enables interaction between electrons, adjusting the chemical states of the active metal and enhancing catalytic performance in hydrogenation.

Summary: Due to their low cost and high capacity, cobalt-free lithium-rich layered oxides have become one of the most promising cathodes for high-energy lithium-ion batteries. However, these cathodes suffer from voltage decay due to various reasons, such as oxygen release and transition metal migration. In this study, a Co-free Li-rich layered cathode with a very small volumetric strain was successfully constructed, leading to improved voltage stability and structural integrity during prolonged cycles.
