Molecular orbital and DFT studies of the alimemazine radical cationResearch on Chemical Intermediates - Tập 26 - Trang 739-745 - 2000
Ke-Sheng Song, Lei Liu, Chen -Rui Hou, Xiao -Song Li, Qing -Xiang Guo
Semiempirical molecular orbital methods including CNDO, MNDO, AM1 and PM3, and density function theory method B3LYP/3-21G(d) were employed in the study of the alimemazine radical cation. It was found that PM3 was much better than CNDO, MNDO and AM1 in the structural optimization. The bond lengths and bond angles by PM3 were close to the experimental data, and comparable with the results by the den...... hiện toàn bộ
Synthesis and characterization of Mg–M (M: Al, Fe, Cr) layered double hydroxides and their application in the hydrogenation of benzaldehydeResearch on Chemical Intermediates - Tập 40 - Trang 931-946 - 2013

Layered double hydroxides or hydrotalcite-like compounds with different kinds of metal ions (Mg–Al, Mg–Fe and Mg–Cr) in the brucite-like sheets were prepared by a co-precipitation method with Mg/M3+ molar ratio of ~2. The hydrotalcites were characterized by chemical analysis, X-ray diffraction, Fourier transform infrared spectroscopy, temperature programmed reduction, SEM microscopy, and specific ...... hiện toàn bộ
An ESR study of the radical interactions of NOx with lignin-containing pulps and papers and several model lignin compoundsResearch on Chemical Intermediates - Tập 21 Số 3 - Trang 425-439 - 1995
Pemberton, R. S., Depew, M. C., Pollington, S. D., Wan, J. K. S.
The reactions of alkyl peroxyl radicals with cellulosic and lignin-containing papers have significance in both the problems of brightness reversion and paper aging phenomena. Since transient peroxyl radicals are elusive to ESR and other spectroscopic detection, we have explored the controlled study of the interactions of nitrogen oxides with paper and some model lignin compounds in solution as a c...... hiện toàn bộ
Effect of zero-valent iron on biological denitrification in the autotrophic denitrification systemResearch on Chemical Intermediates - Tập 44 - Trang 6011-6022 - 2018
Jin suo Lu, Ting ting Lian, Jun feng Su
This study investigated nitrate removal using biological denitrification by the iron-reducing bacteria strain CC76 combined with zero-valent iron (ZVI) in simulated groundwater under anaerobic conditions. The mechanism of nitrate reduction as well as the process of iron cycling by strain CC76 and ZVI were studied. During growth experiments, the strain CC76 showed the ability to utilize Fe2+ (elect...... hiện toàn bộ
