Summary: Mechanically treated fly ash was used to provide Al and Si atoms for zeolite synthesis. The combination of mechanical activation and hydrothermal synthesis improved the dissolution of activated fly ash and the crystallization of zeolites. The obtained zeolite materials exhibited high crystallinity and a large specific surface area. This study provides important data for utilizing fly ash resources and synthesizing practical zeolites.

Summary: Coal fly ash (CFA) is an industrial solid waste containing rare earth elements (REEs), which are important materials in various industries. This study investigates the extraction of REEs from CFA by desilication and the influence of different acids. The results show that desilication increases the leachable amount of REEs and the inter-correlation between light and heavy rare earth elements. The choice of acids also plays a crucial role in the extraction process.

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: Coal combustion produces abundant energy, as well as significant amounts of coal fly ash (CFA) and CO2 emissions. This study proposes a multi-win strategy using CO2 as both a precipitator and template for the synthesis of mesoporous silica. The synthesized silica powders had a high specific surface area and pore volume. The study successfully achieved the goals of CFA disposal, CO2 storage, and valuable silica material production, paving the way for large-scale industrial applications.

Summary: Enzymes play a crucial role as biological catalysts in accelerating biochemical reactions in living organisms. This study proposes a convenient method for monitoring enzymatic catalytic processes using native top-down mass spectrometry. By exploring the heterogeneity of the chymotrypsin sample and using tandem mass spectrometry, the researchers were able to monitor covalent and noncovalent enzymatic complexes, substrates, and products during catalysis. The results demonstrate that this method has the potential to be a promising tool for characterizing biocatalysts.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.

Summary: The study developed a split aptamer-based sandwich-type ratiometric biosensor for the detection of 17 beta-estradiol (E2) using photoelectrochemical and electrochemical assays. The biosensor utilized split aptamer fragments to recognize E2 and trigger a hybridization chain reaction, resulting in the production of double-stranded DNA labeled with CdTe quantum dots. This DNA complex was able to sensitize CdTe quantum dots and generate response signals for E2 detection. The developed biosensor demonstrated high sensitivity and accuracy with two linear ranges and low detection limits.
