Abstract Absorption by aqueous solutions of alkanolamines is the most mature technology for removing carbon dioxide (?? 2 ) from natural gas, off-gases power engineering, and other mixtures. The possible presence oxygen in gas mixture being treated or air leakage into absorption treatment system leads to oxidative degradation amine deactivation liquid with formation a wide range corrosion-activ...

Hyperpolarized (hp) (129)Xe and hp (83)Kr for magnetic resonance imaging (MRI) are typically obtained through spin-exchange optical pumping (SEOP) in gas mixtures with dilute concentrations of the respective noble gas. The usage of dilute noble gases mixtures requires cryogenic gas separation after SEOP, a step that makes clinical and preclinical applications of hp (129)Xe MRI cumbersome. For h...

and the lepton interactions on the other hand. We note further that the quantities xpr C yx ip and ipT C yxy5y> are covariants not only under real but also under special complex transformation as can be proved easily by using relation (8 c). As to the quantization, we have already remarked above, that one can perhaps make use of the linearity of the field equation in the “intrinsic” system by w...

Microwave heating was employed for preparation of the standard gas of volatile organic compounds (VOCs) and semivolatile organic compounds (semi-VOCs) by using a 1000 W commercial domestic microwave oven and 1 L gas-sampling bulbs. The VOCs investigated were benzene, chloroform, 1,3-dichlorobenzene, tetrachloroethylene, toluene, and 1,1,2-trichloroethane, and the semi-VOCs used were the polychl...
