The influence of tautomerism and nucleophilic addition on chelidamic acid and chelidonic acid, compounds with similar molecular weights but different hetero atoms, was investigated in aqueous organic redox flow batteries.
L-Cysteine metabolism is one of the most important modifications not only in human metabolism but also in cysteine-derived natural products. This review focuses on the catalytic mechanisms of metalloenzymes involved in unusual cysteine modifications.
The high-pressure intrusion–extrusion of water in ITE-, CDO- and MTF-type zeosils has been studied. The relationship between the zeosil structure, particularly, pore size and topology, and intrusion-extrusion characteristics is discussed.
Synthetic zeolites present a near-ideal environment for catalytic conversion and separation of molecules. Top-down engineering of porosity expands the capabilities of zeolites obtained by bottom-up synthesis.
Beckmann rearrangement of three kinds of oximes to lactams on MFI zeolite nanosheets was investigated to elucidate the catalytic reaction sites, silanols.
