Summary: A comparative study on the photodetection properties of CdS thin films deposited at different cadmium chloride concentrations revealed that the increased cadmium salt concentration led to changes in crystal phase, film thickness, and photosensitivity. The photosensitivity strongly depends on factors such as film thickness, quantum confinement effect, and sulfur vacancy amount in samples grown via the CBD method.

Summary: The influence of europium on the structure and luminescent properties of CaWO4 thin films was investigated, and the sputtering yields of different compounds were studied. The results showed that the compositions of the deposits matched those of the targets, and the lattice constants increased under certain conditions. The preferential growth along a specific crystal plane also increased due to the substitution of Ca2+ with Eu2+. Doping of Eu led to improved photoluminescence performance of the films.

Summary: Non-precious transition metal oxides, such as the perovskite-type oxide LSCF, show potential as cost-effective alternatives to noble metal electrocatalysts. However, the catalytic activity of LSCF prepared by conventional methods for the oxygen reduction reaction (ORR) needs improvement. In this study, LSCF prepared by spray pyrolysis process demonstrates high ORR activity, attributed to its rich surface edges and oxygen vacancy.

Summary: In this study, directional charge transfer channels were constructed using carbon dots/carbon nitride (CCN) nanotubes and FeOOH/FeCo layered double hydroxide (FFC) nanosheets, which significantly improved the photo-assisted overall water splitting performance. Experimental investigations and DFT calculations demonstrated that the interfacial C-O-Fe bonds between CCN and FFC served as charge transfer channels, facilitating the migration of photoexcited carriers between their surfaces. The in situ oxidized Fe/Co species triggered lattice oxygen activation, leading to the construction of the Fe-Co dual-site as the catalytic center and effectively lowering the energy barrier for water oxidation. As a result, the CCN@FFC electrode exhibited multiple functionalities in photoelectrocatalysis, achieving low overpotentials for photo-assisted hydrogen evolution, oxygen evolution, and overall water splitting.

Summary: In this study, single-crystalline cobalt carbonate hydroxide hydrate (CCOH) nanowires with high oxygen evolution reaction (OER) activity were prepared using a doping-induced facet transformation strategy. The Cu-doped (020)-faceted CCOH nanowire arrays exhibited outstanding OER performances with a low overpotential of 210mV at 10mA cm(-2) and a Tafel slope of 67mV dec(-1) in alkaline medium, as well as extremely long-term durability over 36 h. The findings demonstrate that doping-induced facet engineering is an effective strategy to design and develop highly active catalysts.

Summary: This study combines density functional theory calculations with experiments to explore the mitigation behavior of Mg dopant in layered sodium-ion battery cathodes. The study reveals that Mg dopants are pumped into Na layers from TM layers during the void formation caused by Na extraction, forming Mg-enrich regions in the TM layer. This void-pump effect effectively suppresses the phase transition and improves the cycling performance of the battery.
