Summary: Rice husk, a biomass residue from rice production, is rich in silica and lignocellulose, providing potential carbon sources for functional carbon materials. This study presents a green utilization strategy for converting lignin and cellulose components in rice husk into hierarchical porous carbon and cellulose-based separators. The obtained materials were used in high-rate electrochemical zinc ion capacitors, while silica and potassium sources were recycled as nano-sized particles and powders. This work establishes a general route for green utilization of rice husk biomass and contributes to the development of functional carbon materials and energy storage devices.

Summary: This study aims to improve the mechanical properties and durability of alkali-activated slag concrete (AASC) by introducing rice husk ash (RHA) and silica fume (SF). The experimental results suggest that RHA and SF can substantially enhance the physical, mechanical, and durability properties of AASC. The study also finds that RHA has a more significant effect, possibly due to its higher silica content and finer particle size.

Summary: In this study, amorphous silica powders (1-SiO2 and 2-SiO2) and activated carbon with few-layer graphene were derived from rice husk using a simple and efficient process. The synthesized samples were characterized and the feasibility of using them as anode materials for Li-ion batteries was evaluated. The 2-SiO2 material exhibited a large specific surface area, high purity, and large pore volume, resulting in a reversible capacity of about 841 and 442 mAh g-1 (1st and 50th cycle) with a coulombic efficiency higher than 95%. The activated carbon demonstrated the highest initial discharge specific capacity and stable reversible capacity after 50 cycles, with a coulombic efficiency higher than 90%.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
