A review of transition metal‐based bifunctional oxygen electrocatalysts Tập 66 Số 8 - Trang 829-865 - 2019
Kassa Belay Ibrahim, Meng‐Che Tsai, Soressa Abera Chala, Mulatu K. Berihun, Amaha Woldu Kahsay, Taame Abraha Berhe, Wei‐Nien Su, Bing‐Joe Hwang
AbstractElectrochemical energy storage and conversion devices play a key role in the development of clean, sustainable, and efficient energy systems to meet the sustainable growth of our society. However, challenging issues including the sluggish kinetics of oxygen electrode reactions involving the oxygen reduction reaction (ORR) and the oxygen evolution reaction (...... hiện toàn bộ
A Journey of Metal‐metal Bonding beyond Cotton's Quadruple Bonds Tập 61 Số 1 - Trang 9-26 - 2014
Shao‐An Hua, Yi‐Chou Tsai, Shie‐Ming Peng
AbstractWhereas the study of the Cotton's quadruple bonding between two metal atoms has been mature, exploration of bonding, potential applications and reactivity in linear oligonuclear metal complexes and quintuple bonded dinuclear compounds is currently underway. Stabilized by four long‐chain organic ligands containing various numbers (3‐13) of nitrogen donors, m...... hiện toàn bộ
Applications of Highly Sulfated Cyclodextrins for Enantiomeric Separation by Capillary Electrophoresis Tập 46 Số 5 - Trang 847-860 - 1999
Fu‐Tai A. Chen, Ramon A. Evangelista
AbstractSeparation of enantiomeric pairs of compounds by capillary electrophoresis (CE) was performed using highly sulfated α‐, β‐ and γ‐cyclodextrins (HS‐CDs). CE analysis of the HS‐CDs using indirect absorbance detection showed that the new class of chiral selectors has substantially higher degrees of sulfation and narrower heterogeneity than those used in previo...... hiện toàn bộ
Hypervalent Iodine(III) Sulfonate Mediated Synthesis of Quinoxalines in Liquid PEG‐400 Tập 56 Số 4 - Trang 683-687 - 2009
Pei‐Ying Lin, Rei‐Sheu Hou, Huey‐Min Wang, Iou‐Jiun Kang, Ling‐Ching Chen
AbstractPEG‐400[poly(ethylene glycol‐400)] is used as a “green” recyclable solvent in the one‐pot synthesis of quinoxalines by reaction with aryl ketones, hypervalent Iodine(III) Sulfonate, and o‐phenylenediamines. Significant rate enhancements and improved yields have been observed.
Constituents of the Heartwood of Diospyros Eriantha Tập 41 Số 2 - Trang 195-198 - 1994
Chien‐Chih Chen, Hsi‐Jung Yu, Jun‐Chih Ou, Tzu‐Ming Pan
AbstractThe isolation and identification of fifteen compounds from the heartwood of Diospyros eriantha are described. Their structures were determined on the basis of spectral evidence and/or comparison with authentic samples. These compounds include three steroids (stigmast‐4‐en‐3‐one, stigmast‐4‐ene‐3,6‐dione, and 3β‐hydroxystigmast‐5‐e...... hiện toàn bộ
