Single-electron transfer, a major reaction pathway in organic chemistry. An answer to recent criticisms Nonlinear systems can not be totally determined by the conjugate pairs of through and across variables routinely used in nonequilibrium thermodynamics and ... EC Ashby - 《Cheminform》 被引量: 33...
(~1 kV) was applied via a platinum wire. For IM-MS measurements, corrected N2CCS values of ions were calculated by using poly-DL-alanine in the Major Mix IMS/Tof calibration kit as the calibrant, and calibration was fitted by linear fit method. 7.0 V, 7.5 V, and 8.0 V ...
Catalyst‐controlled vinylogous aza‐MBH reactions of vinylcyclopentenone were performed, and it was found that the α‐adducts were exclusively obtained by DABCO‐catalysis, while the γ‐adducts were the major products by DMAP‐catalysis. We report here that the rate‐determining step of the DABCO...
Saccharides, one of the major classes of water-soluble organic compounds (WSOC) in atmospheric aerosols, are ubiquitous over the continental, marine, and polar regions (Chen et al., 2013; Fu et al., 2012). Atmospheric saccharides usually include anhydrosaccharides (e.g., levoglucosan, galactosa...

According to the method, the value of a given physico-chemical property is determined from the molecular composition of the sample, obtained from two-dimensional gas chromatography (GC-2D). The method comprises three major stages: A—carrying out two-dimensional gas chromatography of the petroleum ...
Certain regularities in the oxidation of UO2 by manganese dioxide in sulphuric acid solution with and without the introduction of iron ions are examined. It is shown that the magnitude of the oxidation-reduction potential gives an indication of the potentialities of the method only and does not ...
is possible, but was incomplete. In the hexasaccharidic fraction, the absence of ΔIs-Iaid-IIsgluand ΔIs-IIIaid-IIsglushowed that they were completely cleaved. On the other hand, ΔIs-IIaid-IIsgluwas still present as a major constituent of the hexasaccharidic fraction. Other constituents ...
For prostate cancer patients, a major issue is that the androgen receptor numbers in cells increase in many prostate cancers after chemotherapy (Culig et al., J Cell Biochem. 2006; 99:373-381). This is why new drugs, such as Zytiga™ and now Enzalutamide (MDV3100) have been developed ...
The cytochrome P450 enzyme family is the major catalyst of drug biotransformation reactions, and can be used in vitro to determine drug binding and drug metabolism in the tissue-engineered systems of the present invention. Assays for monitoring enzyme metabolism, including cytochrome P450 enzyme ...
