Summary: In this study, commercial mineral and biological humic acids (CHA and BHA) derived from coal and rice husk were investigated as effective adsorbents for Pb(II) removal. The results showed that both CHA and BHA exhibited high adsorption capacities, good regeneration, and recycling performance. The adsorption mechanisms involved electrostatic interaction, surface complexation, ion exchange, and 7C-7C interaction for BHA.

Summary: Rice husk is a valuable agricultural biomass that can be used to produce high-purity SiO2 and Si. This study conducted a mechanochemical experiment to convert rice husk ash into porous Si using attrition mill and various acid leaching and heat-treatment conditions. The results showed the possibility of using eco-friendly lactic acid instead of harmful hydrochloric acid, the conversion of heat-treated GRHA to Si without acid leaching, and the importance of carbon content in RHA and GRHA for Si conversion.

Summary: A Ni/SAPO catalyst is prepared using hierarchical silicoaluminophosphate (SAPO-11/SAPO-31) molecular sieves as supports to improve the low temperature fluidity of biodiesel. Carbon-silicon composites from rice husk ash (RHA) are used as a cost-effective and ecofriendly approach to obtain the carbon-silicon composite, which acts as the silicon source and mesopore filler. Microwave irradiation assists in achieving a lower crystallization temperature and shorter duration. Ni/SAPO catalysts exhibit a high conversion of stearic acids to form n-/isoparaffins. These results are important for the development of efficient catalysts for bio-oil upgrading and provide a reference for the synthesis of other types of SAPO molecular sieves.

Summary: Agriculture plays a crucial role in ensuring food security, but the generation of solid wastes and utilization of agrochemicals have negative environmental impacts. The rice and paddy industry is a major contributor to waste management issues. In low and middle-income countries, rice husk is an underutilized agro-waste. This study developed a simple and inexpensive method to extract mesoporous silica nanoparticles from rice husk, which has potential agricultural applications.

Summary: In this study, laterite and rice husk ash-based alkali-activated materials (AAMs) were prepared with different RHA contents for the removal of malachite green dye from water. The incorporation of RHA improved the microstructure of laterite-based geopolymers. Geopolymerization increased the adsorption rate and capacity of the geopolymers compared to laterite. Electrostatic interactions and ion exchange were identified as the adsorption mechanisms. These results demonstrate the suitability of LA-RHA-based AAMs for the efficient sequestration of malachite green in aqueous solution.

Summary: This study investigated the adsorptive interaction between rice husk ash and Ofloxacin antibiotic, evaluating the possibility of using it as a building material after solidification. The majority of Ofloxacin was found to be encapsulated inside the cement, suggesting that the leachate from the solidified rice husk ash may not contain sufficient Ofloxacin to eliminate the growth of bacteria such as E.coli and Bacillus subtilis.

Summary: The use of glass sand and rice husk ash in concrete production saves natural sand resources and promotes waste recycling. The pozzolanic effect of rice husk ash reduces the alkali-silica reaction caused by glass sand and cement slurry. The addition of glass sand improves tensile strength and cyclic compression performance, while rice husk ash enhances compressive and splitting tensile strength.

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.

Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
