Summary: The objective of this study was to develop simple and easy methods to prepare polymorphic HfO2 thin film materials with the best balance of patterning potential, reproducibility and stability. Nanostructured HfO2 thin films were synthesized by two different methods: deep ultraviolet (DUV) photolithography and electrophoretic deposition (EPD) of HfO2 nanoparticles. The morphology, composition and crystallinity of the HfO2 nanoparticles and thin films were investigated, and the results showed that both DUV photolithography and EPD are suitable methods to prepare controllable and tunable HfO2 nanostructures.

Summary: Ternary complex oxides show significant dependence on structure and functionalities based on their composition. The effect of cation stoichiometry on the physical properties of ZnGa2O4 is well known, but its impact on ultraviolet photodetection behavior is not clear. In this study, a combinatorial pulsed laser deposition technique is used to create graded composition in ZnxGa1-xO films, and their effects on phase, crystallinity, and bandgap are investigated. The photodetection performance is compared by fabricating metal-semiconductor-metal (MSM) photodetectors. The study reveals the optimal compositional range for the best device performance and sheds light on composition-dependent evolution in ultrawidebandgap semiconductors for high-performance ultraviolet photodetection.

Summary: The study investigates the structural and transport properties of polycrystalline ZnO films deposited by ALD at different growth temperatures. The electrical properties of the films are significantly influenced by the substrate and growth temperature, with changes in crystallite size affecting carrier scattering. ZnO layers on silicon exhibit lower strain and dislocation density compared to those on sapphire, and both annealing and substrate choice impact film characteristics such as hydrogen impurity concentration.

Summary: It is important to develop cost-effective, fast-response and portable acetaldehyde sensors to monitor the formation of this highly toxic contaminant. This study evaluated the potential use of ZnGa2O4 and ZnGa2O4:N films as vapor sensors of ethanol containing acetaldehyde. The prepared sensors based on ZnGa2O4 films showed high sensitivity to acetaldehyde, allowing identification of acetaldehyde in ethanol (300 ppm). Results suggest that ZnGaON may be considered a potential candidate for the development of an efficient screening test for a highly sensitive and selective identification of acetaldehyde in beverages, foods, or fuel.

Summary: We demonstrate the conformal chemical vapor deposition of boron carbide thin films using triethylboron as a single source precursor on silicon substrates with 8:1 aspect-ratio morphologies. The films deposited at temperatures below 450°C exhibit excellent step coverage, attributed to the low reaction probability at lower temperatures. The boron carbide films are determined to have B-B, B-C, C-B, and C-C chemical bonds and show a boron-rich composition of approximately B5C.

Summary: This study investigates the effect of oxygen flow on the properties of ZnGa2O4 thin films and the performance of photovoltaic devices. The ZnGa2O4 films grown in an oxygen-rich atmosphere exhibit better crystallinity and fewer oxygen vacancies, leading to excellent device performance. Suppressing oxygen vacancies also prevents persistent photoconductivity under low light irradiation. The study confirms that sputtering in an oxygen-rich atmosphere is an effective strategy for producing high-performance ZnGa2O4 thin films for solar-blind photodetectors.

Summary: ZnGa2O4 and ZnGa2O4-beta-Ga2O3 thin films were prepared using aerosol-assisted chemical vapor deposition. Amorphous ZnGa2O4 and Ga2O3 films were formed initially, and then converted to crystalline zinc gallate and heterostructure zinc gallate films through annealing. The ZnGa2O4-beta-Ga2O3 thin films exhibited enhanced photocatalytic activity due to the formation of type-II band alignment at the interfaces, resulting in improved photoinduced charge separation.

Summary: In this study, ZnGa2O4 films were deposited with different nitrogen impurity concentrations and post-annealed at different temperatures in NH3 atmosphere. The nitrogen-doping led to a decrease in optical band gap and structural changes, while secondary ion mass spectrometry analysis showed uniform distribution of nitrogen atoms in the film. The narrowing of the optical band gap was attributed to the hybridization of Zn3d and N2p orbits, promoting p-d repulsion in the valence band and forming a hexagonal wurtzite phase.

Summary: Soil respiration in farmland, an important source of atmospheric CO2, was investigated in this study. Factors such as wind speed were found to significantly affect soil respiration rates, with root respiration being negatively correlated with wind speed. The decrease of farmland soil respiration caused by wind can be regulated through the use of artificial windbreaks or by adjusting the row space of crop planting. Further studies are needed to confirm these findings and explore additional factors influencing soil respiration rates.

Summary: This study conducted a regional study of annual gross primary productivity (AGPP) for grain production and terrestrial carbon sequestration based on 641 site measurements in China. The optimal mapping scheme was determined by analyzing various prediction tools, variable combinations, and mapping approaches, and the random forest regression tree model performed the best in predicting observed AGPP variations. Mapping AGPP through predicting AGPP per leaf area (PAGPP) showed the superior performance in explaining AGPP variations. This study provides a methodological support for mapping regional AGPP from site measurements.

Summary: Chiral boronic esters can be synthesized through an asymmetric nickel-catalyzed borylative coupling reaction between alkyl halides and terminal alkenes. The use of a chiral bisoxazoline ligand enables this reaction to proceed with high regio- and enantioselectivity. This method offers a three-component strategy for accessing alpha- and beta-stereogenic boronic esters from readily available starting materials. Additionally, it simplifies the synthesis of several drug molecules.

Summary: Arid sandy areas, such as the Hexi corridor in northwestern China, have been extensively used for solar photovoltaic (PV) system construction due to their potential for solar power generation. However, the spatial variability of vegetation and soil properties across different PV panel locations in these regions remains unclear. In this study, we assessed the vegetation community and soil properties at multiple locations within and near a PV station in the Hexi corridor. Our findings reveal differences in biomass, plant diversity, and soil properties inside and outside the PV station. Additionally, soil water content was highest under the PV panels, and the presence of PV panels positively influenced vegetation and soil properties.

Summary: We have developed a method for chain-walking carboborations of cyclohexenes based on nickel catalysis, achieving site- and stereoselective control of chain-walking on rings. Unlike the 1,4-trans-selectivity in polymer science, our reactions exhibit a high level of 1,3-regio- and cis-stereoselectivity. This study provides a concise and modular method for the synthesis of 1,3-disubstituted cyclohexylboron compounds, with the incorporation of a readily modifiable boronate group enhancing its synthetic potential.
