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 and coal-based products have negative impacts on human health and the global climate, so their use should be approached with caution. This comprehensive study investigates the elemental configuration and impact on the ecosystem of coal-derived samples, specifically fly-ash. Various elements and minerals were found in the samples, including heavy metals such as chromium and lead. The study also revealed the presence of irregularly shaped minerals and unburnt carbon in the fly-ash, which can reduce the burning efficiency of coal.

Summary: This study successfully developed four new Au nanoconjugates radiolabeled with technetium-99m via thiol-bearing ligands attached to the NP surface. The functionalized AuNPs showed excellent in vitro stability and high radiochemical purity, demonstrating their potential application in multimodality imaging or in vivo tracking of drug-carrying AuNPs.

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: Disposal of coal fly ash (CFA) is controversial due to the release of heavy metals into the ground and aquifers, posing risks to communities and the environment. However, utilizing CFA as fill material in embankments can lead to economic and environmental benefits. This study evaluated the environmental effects of using CFA versus sand through life cycle assessment (LCA) and found that utilizing CFA in embankments reduces impact categories compared to landfilling.

Summary: This study demonstrates the preparation and characterization of kaolin supported Au nanoparticles using Mentha extract as a green reluctant and capping agent. The study also evaluates the cytotoxicity and anti-cervical carcinoma properties of the prepared nanocomposite on different cervical carcinoma cell lines. The results show that the Au nanoparticles are homogeneously dispersed on the modified kaolin surface, and the nanocomposite exhibits dose-dependent reduction in the viability of malignant cervical cell lines.

Summary: A new long chain tetra-nitrogen donor Schiff base ligand and its molecular cadmium (II) complexes were synthesized and characterized in this study. Nanostructured cadmium chloride and iodide chelate complexes were also prepared for the synthesis of nanostructure cadmium oxide. The compounds exhibited multi-step decomposition with metallic Cd or cadmium salt residue. The complexes showed promising antimicrobial activities against selected pathogens. Cd(SB)Cl2 was identified as the most destructive compound in DNA cleavage potency. Cd(SB)Cl2 and Cd(SB)Br2 demonstrated the best antioxidant activity. Cd(SB)Br2 exhibited higher cytotoxicity against human breast cancer and prostate cancer cell lines.

Summary: A large amount of coal fly ash is dumped in fly ash ponds every year, which leads to water pollution due to the presence of toxic heavy metals. Synthesizing silica nanoparticles from coal fly ash and using them for heavy metal removal is an economical and efficient approach. Researchers successfully synthesized nanosilica from coal fly ash and achieved 40-90% removal of heavy metals from fly ash aqueous solution.
