Summary: This study synthesized a composite photocatalyst with a Z-scheme charge transfer for hydrogen generation without bias. The optimized photocatalyst demonstrated improved hydrogen generation rate and photocurrent, about 70% higher than pure WO3. These enhancements were attributed to enhanced light absorption, extended conduction band level of BiVO4, and unique charge transfer behavior in the Z-scheme structure.

Summary: The cellular segmentation patterning of undoped and Zr doped Tungsten Oxide coatings engineered by aerosol assisted Chemical Vapor Deposition (AACVD) onto silica glass at 400 degrees C was successfully grown. Various characterization techniques were used to study the morphological, chemical, optical, and electrical properties of the coatings. Zr doping resulted in fractal cauliflower patterning and modified the crystalline structure of the coatings. The coatings exhibited high absorptive nature and widened band gap with Zr doping, leading to decreased electrical resistivity.

Summary: In this study, the antibacterial properties of bioreduced graphene oxide (B-rGO) were compared to that of commercial reduced graphene oxide (C-rGO). B-rGO demonstrated good antibacterial activity as confirmed by Scanning Electron Microscopy (SEM). Fourier transform infrared spectroscopy (FTIR) analysis confirmed the presence of numerous oxygen-containing functional groups on the surface of B-rGO. Microcalorimetry and flow cytometry analysis showed that the antibacterial activity of B-rGO was inferior to that of C-rGO.

Summary: Alkaline water electrolysis is a promising approach for green hydrogen generation, with the importance of anodic oxygen evolution reaction (OER) in coupling with cathodic hydrogen evolution reaction. The development of highly active and durable OER catalysts based on earth-abundant elements has gained attention, but their performance under high current densities (HCDs >= 1000 mA cm(-2)) has been less emphasized. This review summarizes the effects of HCD on catalytic performance and provides design principles for efficient and robust OER electrocatalysts, focusing on recent progress working above 1000 mA cm(-2). Additionally, summaries and outlooks for achieving OER at industrially relevant HCDs are proposed.

Summary: Ultrathin MoS2-MoO3-x heterojunction nanosheets were used as biocompatible and visible light-sensitive stimulator layers for controlled differentiation of human neural progenitor cells (hNPCs) into nervous lineages. The differentiation of hNPCs was increased on MoS2-MoO3-x due to biophysical cues and further increased on rGO/MoS2-MoO3-x due to a synergistic effect induced by the rGO. MoO3-x domains induced p-type doping in MoS2-MoO3-x, while photostimulation led to higher differentiation into glial cells. The presence of rGO in rGO/MoS2-MoO3-x promoted ultrafast electron transfer and increased neuronal differentiation of hNPCs.

Summary: Chemical vapor deposition (CVD) is widely used to produce high quality 2D transitional metal dichalcogenides (2D TMDCs). However, regulation of the X:M molar ratio in CVD growth of 2D TMDCs is challenging due to violent evaporation and large diffusivity discrepancy of metal and chalcogen precursors. In this study, a modified spatially confined strategy (MSCS) is proposed to selectively regulate the growth of 2D WS2. A comprehensive growth management of atomically thin WS2 is achieved, including the versatile controls of domain size, layer number, and lateral/vertical heterostructures.

Summary: This study developed a homemade Neisseria meningitidis recombinant antibody (scFv-Fc) by connecting the fragment crystallizable (Fc) region of a human antibody with a mouse recombinant antibody (single-chain variable fragment antibody, scFv), and characterized it using the SOEing PCR technique. An optimized gold coating agent for the scFv-Fc/Au NP conjugation (citrate agent) was found among three common agents (citrate, allylamine hydrochloride, and polyvinyl alcohol) with different surface charges. The stability of the scFv-Fc/protein A-G in the presence of a N-succinimidyl 3-(2-pyridyldithio) propionate (SPDP) linker was also investigated using the docking method.

Summary: In this study, a dual-energy X-ray radiography system was simulated using the MCNPX code. Material discrimination curves for graphite, aluminum, steel, and lead materials were obtained using four algorithms: log-log, R-T, r-theta, and alpha(1)-alpha(2). The results showed that the R-T, r-theta, and alpha(1)-alpha(2) algorithms performed better. Additionally, the R-T algorithm was found to be a better choice for obtaining material discrimination curves in dual-energy radiography systems due to less overlap of the curves at low sample thicknesses.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: This study explores the potential of biphenylene as a nanocarrier for the delivery of the anticancer drug cisplatin. It is found that biphenylene offers physical stability, rapid release rate, solubility, and bio-compatibilities compared to other nanocarriers. The adsorption of cisplatin on the surface of biphenylene involves charge transfer from cisplatin to biphenylene. The drug is shown to be released at body temperature in an acidic environment. Biphenylene also exhibits excellent cytotoxicity activity and cellular uptake of the drug. Overall, biphenylene shows promise as a potential nanocarrier for cisplatin delivery.
