Summary: Oxygen ingression has been shown to decrease the carrier lifetime of Sn-based perovskites, but the mechanism behind this is unknown. First-principles calculations reveal that oxygen forms substitutional O-I by combining with native I vacancies (V-I), significantly increasing the recombination rate of V-I. This explains the sharp decline of carrier lifetime in perovskites exposed to air. These insights offer a way to improve device performance in Sn-based perovskite optoelectronics operating in ambient air through anion engineering.

Summary: Oxygen ingression has been shown to decrease the carrier lifetime of Sn-based perovskites, and our calculations reveal that oxygen tends to form substitutional OI, which remarkably increases the recombination rate of native I vacancies (VI). This explains the observed decline of carrier lifetime in perovskites exposed to air. The enhanced carrier recombination is due to a smaller electron capture barrier of OI, resulting from lattice strengthening and suppressed structural relaxation upon electron capture. These insights offer a route to improve device performance in Sn-based perovskite optoelectronics operating in ambient air.

Sorbent-coated carbon fibers prepared via roll-to-roll process show high CO2 adsorption and fast CO2 desorption through Joule heating. The simplicity and modularity of these fibers have the potential to enhance the productivity of DAC systems.

Summary: Developing diverse synthetic routes to prepare various crystalline covalent organic frameworks (COFs) and enriching the COFs family is crucial. In this research, the Kro''hnke oxidation method was used to construct two crystalline nitrone-linked COFs (CityU-1 and CityU-2) through the ingenious design of precursors and careful control of polymerization conditions. The as-obtained crystalline COFs were characterized and showed potential applications, such as high specific surface area and I-2 capture capacity.

Summary: This review presents the advances in cotton heterosis and hybrid cultivar development, including hand-emasculation and pollination, cytoplasmic male sterile lines, and genic male sterile lines. Three types of hybrid cultivars have been developed and planted in cotton production, with most commercially planted hybrids being produced by hand-emasculation and pollination. The F-2 generations of these hybrids usually outperform the check cultivars in yield by up to 5 to 15%. Additionally, GMS genes and mitochondrial genes for G. harknessii CMS have been cloned.

Summary: Six different porous carbons were prepared from cotton-stalk crop residue collected from various locations in India. The properties of these carbons were influenced by the collection sites, leading to variations in their microstructures and CO2 uptake performances. These carbons exhibited moderate to good CO2/N-2 separation selectivity at low temperature and could be reused for CO2 capture.

Summary: This study successfully prepared a pyrazole-directed functionalized leather waste collagen fiber composite and investigated its capture effect and mechanism on iodine vapor. The results showed that the composite had a high iodine capture capacity, which was primarily attributed to the existence of active functional groups and charge transfer between the pyrazole moieties and iodine.

Summary: In order to protect the environment, it is crucial to efficiently capture the radioiodine produced or released as nuclear fission products. Metal-organic frameworks (MOFs) show promise in addressing this issue. The synthesis and characterization of four different MOFs were conducted in this study, with KQ-1 demonstrating the highest iodine adsorption capacity. The presence of aromatic rings in the MOFs structure was found to play a significant role in iodine sorption.

Summary: In this work, two novel compounds [Et3S][AuI4][I-5] (2) were synthesized by ionic liquid (IL) and applied as active layers in monolithic solar cells. These compounds are composed of tetraiodoaurate anions and polyiodide entities, with infinite polyiodide chains in 1 and pentaiodides in 2, resulting in relatively small electronic bandgaps. The deposition of gold iodide/polyiodide compounds onto porous monolithic substrates with subsequent solar cell characterization is demonstrated for the first time in this study. The devices show promising photovoltaic performance and offer new possibilities for materials design, moving away from lead-based photovoltaic materials. The use of simple polyiodide entities in this study enhances the structural and electronic dimensionality of gold perovskite-type anions.

Summary: Exposure of lettuce leaves to copper oxide nanoparticles (CuO-NPs) led to negative impacts on plant growth, photosynthesis, and antioxidant system activity. Transcriptome analysis revealed differential expression of genes related to transporters, metal-associated proteins, endocytosis, and metal ion binding proteins upon CuO-NP exposure. These findings provide insights into the toxicity mechanisms of metal NPs on crops, especially those resulting from foliar exposure.

Summary: Melatonin can effectively delay fruit softening and reduce the incidence of anthracnose on guava fruit. It enhances the antioxidant capacity, reduces oxidative damage, and improves enzymatic and non-enzymatic antioxidants. Melatonin also enhances defense-related enzymatic activities and represses lipase, lipoxygenase, and phospholipase D activities related to lipid metabolism.

Summary: Neutrophils, as the first defense mechanism of the innate system, play a crucial role in injury, infection, and tumor initiation. In the tumor microenvironment, they can either have anti-tumor or pro-tumor functions depending on the surrounding conditions. Tumor cells alter amino acid metabolism and release glutamate, which leads to immunosuppressive phenotypes of neutrophils. The use of a glutamate release inhibitor called riluzole can inhibit tumor growth and restore neutrophils' cell-killing effects.

Summary: This study found that formation of neutrophil extracellular traps (NETs) leads to the appearance of CD11b(+) pericytes after traumatic brain injury (TBI), which have increased permeability and pro-inflammatory profiles compared to CD11b(-) pericytes. Histones from NETs, facilitated by Dectin-1, induce CD11b expression in brain pericytes in a PKC-c-Jun dependent manner, resulting in neuroinflammation and blood-brain barrier dysfunction after TBI.

Summary: One-third of women who delivered via Cesarean section experienced delayed onset of lactogenesis II (DOLII). Primiparous women, those with a serum albumin concentration < 35 g/L, a lower frequency of breastfeeding sessions, and an EPDS score >= 10 were more likely to experience DOLII. These women may require early breastfeeding support to ensure successful lactation.

Summary: The study investigated the accumulation of PFAS in ferns and the relationship between root uptake behavior and root characteristics and PFAS molecular structure. It was found that ferns can accumulate and immobilize PFAS in roots, with PFOS being the dominant compound. Factors such as root length, surface area, and hydrophobicity of PFAS were found to significantly affect root uptake and upward translocation. Long-chain hydrophobic compounds tended to be retained on the root epidermis, while short-chain compounds were quickly translocated upward. This study demonstrated the potential of using ferns for phytostabilization and phytoextraction of PFAS.

Summary: This study investigates the effect of modified atmosphere package (MAP) + 1-methylcyclopropene (1-MCP) treatment on the shelf-life quality of banana fruit after high temperature storage. The results demonstrate that the combined treatment can prevent green-ripe disorder in banana stored at high temperature by reducing ethylene production and respiration, delaying senescence and ripening, and reducing disease incidence and fruit drop. Furthermore, the treatment enhances defense-related enzyme activity and antioxidants, and regulates the contents of endogenous hormones, thus maintaining fruit quality during storage and transportation.
