Summary: This study investigates the impact of heat exposure on the performance of alkali-activated coal fly ashes (AAF). The results show that the mechanical performance varies depending on the exposure temperature and intrinsic properties of the activated ashes. Low-Ca AAFs are found to be more stable compared to high-Ca AAFs. Heat exposure also significantly reduces the thermal conductivity and volumetric specific capacity of all AAFs.

Summary: The availability of traditional siliceous Class F fly ash is decreasing as countries switch to renewable energy sources. To extend the availability of siliceous fly ash, suppliers are distributing blended coal ashes and incorporating other coal combustion products (CCPs) or natural pozzolans. While the characteristics of these blended fly ashes may differ, they perform well in cement-based mixtures.

Summary: Selenium in gaseous form is difficult to retain in solid phases during coal combustion due to its high saturated vapor pressure. Understanding the migration of SeO2(g) on ash particles in the low-temperature zone is essential for controlling selenium emission. The physically-bound Se in fly ash consists of selenium condensation and physical adsorption, with mullite showing the best performance in selenium capture at temperatures between 90-200 degrees C.

Summary: Activated carbon injection is an effective method for removing organic pollutants from coal-fired power plants, with aromatic hydrocarbons and oxygenated volatile organic compounds being the major components. The removal efficiency of organic pollutants is influenced by their physicochemical properties, and increasing the amount of AC injection can enhance the adsorption effect but decrease the adsorption capacity.

Summary: The study evaluated the re-generation of waste fly ash (FA) as cost-effective materials with adsorbent and antibacterial applications. Alkaline/zinc-activated fly ash nanocomposite (A-FA/Zn) was prepared using a one-pot hydrothermal technique, with high surface area and negatively surface charge contributing to enhanced adsorption capacity and antibacterial activity. The findings provide valuable insights for the development of simple, eco-friendly, and low-cost A-FA/Zn with multifunctional applications.

Summary: The research found that the fossilized particulate organic carbon (FOCash) in fly ash, a byproduct of coal burning, has a significant flux in rivers like the Chang Jiang in China. This highly recalcitrant FOCash is difficult to oxidize, unlike the more labile FOCrock derived from shale. The high FOCash flux in the Chang Jiang was attributed to increased coal combustion and construction of dams, leading to a substantial impact of anthropogenic activities on the global riverine FOC flux to the oceans.

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.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. 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.
