This study developed heterogeneous catalysts composed of ZnO and CeO supported on H-ZSM-5 for the direct conversion of methane (CH) and carbon dioxide (CO) into acetic acid. The acid-base and electronic properties were modulated through oxide impregnation and reduction, aiming to create active sites capable of simultaneously activating both reactants. The samples were characterized by XRD, N physisorption, HRTEM/EDS, NH-TPD, CO-TPD, TPR, FTIR, XPS, CO-DRIFTS, and TGA, and tested in a batch reactor at 300 °C and 10 bar.

Waste three-way catalysts (TWCs) and waste LiCoO batteries represent critical environmental challenges due to hazardous components yet contain high-value resources, and their recycling has garnered widespread attention. We propose a novel 'waste-to-waste' synergistic recycling where spent LiCoO batteries reconstruct mineral phases of waste TWCs, enabling co-recovery of platinum group metals and Li/Co without traditional oxidants. However, the environmental performance of this process still requires further analysis.

The development of synthetically-useful biocatalysts requires characterizing the behavior of an enzyme under conditions amenable to preparative-scale reactions. Whole cells harboring the catalyst of interest are often used in such reactions, as protein purification is laborious and expensive. However, monitoring reaction rates when using whole cells is challenging, as cellular debris precludes the use of a continuous assay.

Although there is considerable research into the impact of homicide on surviving family members, research is limited on subjective experiences of those who lost a parent due to homicide during childhood. Through interpretative phenomenological analysis, we conducted and analyzed in-depth semi-structured interviews, to explore lived experiences and perspectives of post-traumatic growth with adults who lost a parent due to homicide as a child. We developed five group experiential themes: 1.

Presented herein is a protocol for the iron-catalyzed [4 + 1] cycloadditions of -Boc-imines with β-ketosulfoxonum ylides through a succession of nucleophilic additions and intramolecular annulation, giving access to functionalized oxazolidine-2-ones in generally good yields. In contrast to the renown Corey-Chaykovsky reaction via N attack to furnish aziridines, this method afforded oxazolidine-2-ones via an O-nucleophilic attack. Features of this strategy include readily accessible starting materials, sustainable catalyst, post-functionalizations of complex molecules, scalability, and exceptional control over diastereoselectivity.
