Summary: This study investigates the influence of calcium content in CFA on the properties of coal fly ash zeolites, as well as the carbon capture capacity of different types of zeolites. The development of efficient adsorbents from CFA with varying composition is expected to contribute to environmental benefits and the advancement of CO2 capture technologies in the context of the circular economy.

Summary: This paper presents a chemoselective and mild procedure for converting a peptide cysteine residue into lanthionine via S-alkylation on aziridine substrates. The method relies on a post-synthetic protocol promoted by molecular sieves and is assisted by microwave irradiation, providing a valuable alternative to the stepwise approach of incorporating lanthionine precursor into peptides.

Summary: The glycosylated alpha-lactalbumin prepared under microwave heating exhibited higher browning, free amino groups, reaction rate constants, and lower activation energy compared to conventional heating. Additionally, it showed greater surface hydrophobicity, total antioxidant capacity, and alpha-glucosidase inhibitory activity. Microwave heating effectively accelerates glycosylation of alpha-lactalbumin and enhances its functional properties and biological activities.

Summary: Charoitite is a unique rock in the alkaline-carbonatite Murun Complex, Eastern Siberia, Russia that contains many rare minerals. The minerals in charoitites belong to Ca(K)-(Na) silicates and have low concentrations of Al, Fe, and Mg. These minerals have high and variable concentrations of water, CO2, and F, indicating a hydrous and volatile-rich crystallization environment. The trace element data show that the rare Ca-(K)-(Na) silicate minerals in charoitites have relatively low content of trace elements and likely act as trace impurities rather than structural components. The REE distribution patterns indicate LREE enrichment and HREE depletion in most of the Ca-(K)-(Na) silicates in charoitite, with the exception of tokkoite and coarse-grained tinaksite. The initial purple/lilac color of charoite is related to Mn and can be altered to brown or white color through weathering and oxidation processes while retaining trace elements. The fractionation of trace elements between minerals in charoitites is consistent with their geochemical properties and limited solid solutions in Ca-(K)-(Na) minerals.

Summary: The study demonstrates the potential of Na/Ca in planktic foraminifera as a new proxy for reconstructing Cenozoic variations in seawater Na/Ca. Culture experiments validate the approach and show that foraminiferal Na/Ca responds to changes in seawater calcium concentration. The down core planktic foraminiferal records consistently show lower Na/Ca during the mid-Miocene than during the late Pleistocene, primarily reflecting changes in seawater calcium concentration.
