Summary: This study investigated the dissolution, clustering, and diffusion behavior of hydrogen in bulk alpha-Al2O3 through first-principles calculations, revealing that the most stable form of hydrogen in this material is the H2 molecule. The strong attraction between two H atoms at neighboring octahedral interstitial sites can lead to cluster formation. Additionally, the high dissolution energy and migration barrier of the H2 molecule in alpha-Al2O3 make hydrogen permeability low.

Summary: Iron-chromium-aluminum (FeCrAl) alloys are being considered for cladding uranium dioxide fuel in light water reactors (LWRs). These alloys have good mechanical properties at high temperatures and excellent resistance to steam attack. Concerns have been raised about increased tritium content in the coolant if FeCrAl is used as cladding instead of zirconium-based alloys. However, research suggests that the presence of oxide layers on the surface of the FeCrAl cladding can greatly reduce tritium permeation, resulting in a two to three orders of magnitude reduction in tritium permeation at temperatures around 277℃-377℃.

Summary: Tritium permeation barrier using ceramic coatings has been developed to prevent tritium leakage in fusion reactor blanket concepts. However, little research has been done on the effects of corrosion on tritium permeation. In this study, zirconium oxide coatings were exposed to different solid breeder pebbles and measured for deuterium permeation flux. The results showed that the pebble composition affected the thickness of the corrosion layer and the permeation behaviors, rather than the coating integrity.

Summary: SiOC coatings were prepared on X70 pipeline steel substrate by a simple dipping method at low temperatures, and their performance of hindering hydrogen penetration was studied through electrochemical hydrogen permeation experiment. The sample thermal-treated at 120 degrees C achieved a low diffusion coefficient of hydrogen of 8.20 x 10-9 cm2 s-1, which was nearly three orders of magnitude lower than 3.58 x 10-6 cm2 s-1 for the X70 steel. This was due to that the amorphous coating did not provide a stable hydrogen diffusion channel, thus limiting hydrogen diffusion. Density functional theory (DFT) calculation further proved that hydrogen molecules were difficult to be adsorbed at different sites on the surface of the coating.

Summary: Long-term nitrogen deposition can change the abundance and community composition of soil nematodes, affecting the soil food web and biogeochemical cycling. In Cunninghamia lanceolata forest, nitrogen addition increased the abundance of bacterial-feeding nematodes but reduced the abundance of plant-feeding nematodes. Furthermore, nitrogen addition indirectly affected the abundances of bacterial, fungal, and plant-feeding nematodes via changes in soil nutrients, soil water content, and pH.

Summary: Despite progress in purifying C5-C9 linear alpha-olefins from Fischer-Tropsch synthesis products, the separation of olefins and paraffins with the same carbon number hampers their industrial development. This study proposes a process that uses zirconocene/methylalumoxane catalyst for selective dimerization of linear alpha-olefins, followed by distillation and catalytic conversion into branched-chain sulfonate surfactants. The resulting surfactants outperform commercially used linear alkylbenzene sulfonate in terms of surfactant properties and detergency performance.

Summary: Celastrol was transformed by Streptomyces olivaceus CICC 23628, resulting in the isolation of two new friedelanes derivatives (CEL-1 and CEL-2) as metabolites. Their structures were elucidated through NMR and HR-MS analysis. In vitro studies demonstrated that CEL-2 could induce apoptosis and block the cell cycle in HCT-116 cells. Western blotting analysis showed that CEL-2 inhibited STAT3 phosphorylation and downstream gene expression. Moreover, SPR analysis confirmed the direct binding of CEL-2 with STAT3 protein. These findings suggest that CEL-2 may have potential as an anti-colorectal cancer agent by inhibiting STAT3 and inducing apoptosis and cell cycle arrest.

Summary: In this study, we developed a reliable method to accurately determine the copy number of STRC based on standard short-read genome sequencing data, which has clinical significance in the screening and diagnosis of genetic hearing loss. Our population analysis revealed that 5.22% of the general population has copy number changes in STRC, almost half of which are clinically significant, including heterozygous and homozygous deletions of STRC. Additionally, we provided population-based evidence of pseudogene-mediated gene conversions between STRC and STRCP1.

Summary: The concomitant pollution of arsenic and antibiotics has been commonly observed in recent environments, and their behavior may differ from when they exist individually. Colloidal ferric hydroxide (CFH) is found ubiquitously in various environments and in this study, it was shown to facilitate the degradation of oxytetracycline (OTC) and the reduction of Fe(III) to Fe(II). Under oxygen-rich conditions, reactive oxygen species (ROS) such as (OH)-O• and O2•- were generated through the reactions between dissolved oxygen (DO) and Fe(II). It was found that (OH)-O• played a dominant role in the oxidation of As(III). Furthermore, the oxidation of As(III) to As(V) resulted in the formation of ferric arsenate, which significantly reduced the risks of As(III) in the environment. Similar transformations were also observed with other iron oxides and different antibiotics. These findings contribute to our understanding of the role of organic pollutants in combined contamination.

Summary: This study investigated the effects of Konjac glucomannan (KGM) on the aggregation patterns and structural properties of weak, middle, and strong gluten. The results revealed that 10% KGM substitution resulted in decreased aggregation energy for middle and strong gluten, but increased for weak gluten. Additionally, 10% KGM enhanced the aggregation of glutenin macropolymer (GMP) in weak gluten, but suppressed it in middle and strong gluten. Furthermore, 10% KGM induced a transition from alpha-helix to beta-sheet in weak gluten, while causing more random-coil structures in middle and strong gluten. The network of weak gluten became more continuous with 10% KGM, whereas it was severely disrupted in middle and strong gluten.

Summary: Phosphorus and cobalt co-doped C3N5 (Co-xP-C3N5) has been developed for peroxymonosulfate (PMS) activation and 2,4,4'-trichlorobiphenyl (PCB28) degradation. Phosphorus doping induces the formation of Co-P and Co-N-P species, which increase the content of coordinated Co and improve catalytic performance. This finding provides a new strategy for enhancing the performance of single atom-based catalysts.
