Summary: Surface charge recombination is a detrimental factor for bismuth vanadate (BiVO4) photo electrochemical (PEC) performance. In this study, a defect rich cobalt (oxy)hydroxides (Co(O)OH) nanolayer was demonstrated as an excellent cocatalyst on BiVO4 to greatly improve PEC water oxidation activity. The self-transformation of metal-organic framework produced an ultrathin Co(O)OH layer with oxygen vacancies, which served as a powerful hole extraction engine and an excellent oxygen evolution reaction catalyst. As a result, the hybrid photoanode of BiVO4/Co(O)OH achieved inhibited surface charge recombination and a prominent photocurrent density, around 2.6-fold higher than the pristine BiVO4. The Co(O)OH cocatalyst nanolayer also significantly reduced the onset potential of BiVO4 photoanodes. This work provides a versatile strategy for preparing oxygen-vacancy-rich cocatalysts on various photoanodes for high-efficient PEC water oxidation.

Summary: By hydrothermal reaction, a carbon nanolayer conformally coated Fe2O3 (C-Fe2O3) as oxygen evolution catalyst (OEC) is loaded on the H-2 plasma treated nanoporous BiVO4 (BVO(H-2)) surface to simultaneously improve the hole extraction ability of the BiVO4 photoanode and accelerate the surface reaction kinetics. It is found that the H-2 plasma induced vacancies in BVO remarkably increases the conductivity, and the C-Fe2O3 enables efficient hole extraction and injection. As a result, the C-Fe2O3/BVO(H-2) photoanode exhibits significantly enhanced photocurrent density and ABPE value compared to the BVO photoanode.

Summary: Transition metal-based cocatalysts are crucial for boosting the surface kinetics of hematite photoanode. However, their effectiveness is limited by the shallow reconstruction process that generates highly efficient metal oxyhydroxides during the oxygen evolution reaction. To overcome this limitation, a Brnsted base-regulated strategy is developed to promote in situ surface reconstruction of cocatalysts on Ti-doped hematite under photoelectrochemical conditions. The resulting CoWO4 cocatalyst-decorated Ti-doped hematite photoanode exhibits significantly enhanced photocurrent density compared to activated Ti-doped hematite and CoOx/Ti-doped hematite. Tungstate promotes the surface reconstruction of cobalt-based cocatalyst, resulting in improved charge separation and transfer efficiency and enhanced performance of the Ti-doped hematite photoanode.

Summary: The slow kinetics of water oxidation is a challenge for photoelectrochemical hydrogen production. In this study, a novel organic-inorganic integrated photoanode system was constructed using MIL-53(Fe) as a cocatalyst to modify Ti-Fe2O3. The Ti-Fe2O3/MIL-53(Fe) exhibited significantly enhanced photocurrent density and water oxidation performance due to iron oxide clusters boosting charge separation and transfer, in-situ etching exposing more reactive sites, and the tight connection reducing interfacial resistance. This work provides an in-depth understanding of in-situ modification of photoanodes by metal organic frameworks.

Summary: The recent rise in air temperatures at high altitudes of the Tibetan Plateau has led to increased glacier melt and retreat, as well as enhanced monsoonal precipitation and increased runoff in lakes. These changes have resulted in rising water levels and alterations in the composition of local aquatic biota. Analysis of sediment cores from Nam Co, an endorheic lake, revealed an increase in chironomid richness since 1956, indicating higher water temperatures and intensified primary productivity. The dominance of littoral chironomid assemblages further suggests increasing lake water levels and flooded shorelines due to increased precipitation and glacial meltwater input.

Summary: In this study, the periods of the W UMa contact binary systems HH UMa and V1175 Her were found to show cyclic variations, possibly due to a Light Travel Time Effect induced by a third body. The cyclic variation in HH UMa has a period of about 20 years and may be caused by a third body with a mass larger than 0.23 times the mass of the Sun. The period increase in V1175 Her, with a rate of about 2x10^(-7) days per year, indicates mass transfer from the less massive component to its companion.

Summary: As a potential probiotic for health promotion, Clostridium tyrobutyricum has limited industrial applications due to its weak tolerance to oxygen stress during fermentation. In this study, we enhanced its oxidative stress tolerance by deleting the perR gene using the CRISPR-Cas system, resulting in improved growth and butyric acid production in the presence of oxygen. Transcriptome analysis revealed upregulation of genes related to redox balance, and changes in metabolisms were observed. Furthermore, phylogenomic analysis suggested that PerR may be a target for engineering in diverse Clostridium species. These findings have implications for the development of robust C. tyrobutyricum strains for butyric acid production in the food industry.
