Progress in heteroatom - containing aluminophosphate molecular sieves
Over the past 30 years, heteroatom-containing aluminophosphate molecular sieves as a prime class of heterogeneous single-site solid catalysts have been quickly developed since the first discovery of aluminophosphate molecular sieves in 1982, and a large variety of such materials with 48 unique zeotype structures have been prepared. This work mainly presents the progress in the development of he...
متن کاملNew hits as phase II enzymes inducers from a focused library with heteroatom–heteroatom and Michael-acceptor motives
The increased activity of phase-II-detoxification enzymes, such as quinone reductase (QR) and glutation S-transferase (GST), correlates with protection against chemically induced carcinogenesis. Herein we studied 11 different chemotypes, pyrazole, 1,2,4-oxadiazole, 1,2,5-oxadiazole, 1,2,3-thiadiazole, 1,2,4-thiazole, 1,3,4-oxathiazole, thienyl hydrazone, α,β-unsaturated-oxime, α,β-unsaturated-N...
متن کاملSyntheses and characterizations of heteroatom-containing open-framework aluminophosphates.
Two heteroatom-containing open-framework aluminophosphates, (C(3)H(4)N(2))(2)FeAl(3)P(4)O(16) and (C(3)H(4)N(2))(2)CrAl(3)P(4)O(16) (denoted as MAPO-CJ50, M = Fe, Cr), have been synthesized by using imidazole as the template under solvothermal conditions. The structure of FeAPO-CJ50 is determined by single-crystal X-ray diffraction, and its analogous structure CrAPO-CJ50 is identified by powder...
متن کاملGating of Quantum Interference in Molecular Junctions by Heteroatom Substitution
To guide the choice of future synthetic targets for single-molecule electronics, qualitative design rules are needed, which describe the effect of modifying chemical structure. Here the effect of heteroatom substitution on destructive quantum interference (QI) in single-molecule junctions is, for the first time experimentally addressed by investigating the conductance change when a "parent" met...
متن کاملHeteroatom-doped highly porous carbon from human urine
Human urine, otherwise potentially polluting waste, is an universal unused resource in organic form disposed by the human body. We present for the first time "proof of concept" of a convenient, perhaps economically beneficial, and innovative template-free route to synthesize highly porous carbon containing heteroatoms such as N, S, Si, and P from human urine waste as a single precursor for carb...
