Summary: This study investigates the application of SnO2-based electron transport layers (ETL) in perovskite solar cells (PSCs). It is found that by controlling the deposition parameters of pulsed laser deposition (PLD) technique, SnO2 films with low roughness can be obtained. The concentration of oxygen in the background gas is also shown to affect the number of oxygen vacancies in the film. Solar cells with methyl-ammonium lead iodide perovskite absorber layer and SnO2 ETL deposited by PLD under optimized conditions achieve power conversion efficiencies exceeding 18%, comparable to those with atomic layer deposited SnO2 ETL.

Summary: In this study, four post-transition metal tin corrole complexes with different numbers of cyano-substituents were synthesized and characterized. Among them, Sn-CDPC and Sn-PBCC are novel compounds. The Sn-TCPC complex exhibits the best electrocatalytic HER performance in organic phase, with an icat/ip and TOF of 13.12 and 25.6 h-1, respectively. The highest TOF (474.3 h-1) and H2 production rate (4.7 mL H2 in 1 h) were achieved by the Sn-CDPC complex in the acetonitrile/water neutral water system.

Summary: Ion-beam-induced deposition using Me3PtCpMe was studied through a combination of UHV surface science research and SEM data. The experiments showed that ion-induced deposition reaction cross sections are approximately two orders of magnitude greater, resulting in deposits with PtC5 stoichiometry. Ion-induced deposition also led to bimolecular methyl radical coupling to produce ethane.

Summary: In this study, ZnO was selectively introduced into the organic microdomains through self-assembly, achieving the preparation of organic-inorganic hybrids. The results showed that ZnO can selectively form composites with liquid crystalline polymers, and the core-shell morphology of the composites was obtained through etching.

Summary: Double layered stacks of ZrO2 and SnO2 films were grown by atomic layer deposition to synthesize thin magnetic and elastic material layers, showing hardness and elastic modulus depending on the order of the constituent oxide films. Nonlinear saturative magnetization could be induced in the stacks with coercive fields up to 130 Oe.

Summary: In this study, the preparation and properties of ALD-SnO2 thin films are investigated. The photoelectrochemical activity and band energetics after calcination and UV-excitation are analyzed, and it is found that calcination enhances the work functions, causes surface coarsening, and decreases the band-gap of ALD-SnO2.

Summary: In this work, a nonconventional growth method using sputter deposition and nanosecond UV pulsed laser annealing was explored to synthesize large-scale MoS2 multi-layer films without post-sulfurization. The successful identification of the optimal process led to the growth of high-quality, (002)-oriented nanocrystalline MoS2 films. This synthesis method can accelerate the integration of large-area 2D materials with Si-based devices, opening up possibilities for various important applications.

Summary: This paper discusses three different types of microstructures as substrates for electrochemical deposition of Au nanodots. The uniform deposition of Au nanodots with controlled density was successfully achieved by adjusting adjustable parameters, and the morphology of the produced hybrid microarchitectures was investigated using scanning electron microscopy. These microstructures are proposed as platforms for the development of complex 3D hybrid micro-nano-architectures with Au nanodots as catalysts.

Summary: Co100-xFex (x = 0; 50; 30; 20) films were prepared by pulse-reverse plating onto Cu foils under different magnetic field conditions. The Fe/Co ratio and magnetic field strength influenced the film morphology and microstructure, showing different growth mechanisms for Co and Co-Fe films.
