The kinetics of H(D) absorption into a b-phase PdHx (PdDx) electrode are discussed numerically, based on the Volmer–Tafel route of the hydrogen (deuterium) evolution reaction and thermodynamic and kinetic data of H(D) in the b-phase PdHx (PdDx). It is found that the asymptotic loading ratio of H(D) is determined only by the Tafel step under galvanostatic conditions. The kinetics of H(D) absorpt...

A technique is described for study of the kinetics of lateral transport of ions across single roots of corn, Zea mays, in short term experiments under steady state conditions. The kinetics of chloride transfer to the vessels reflected the kinetics of absorption of chloride by the root cells. Efflux from the root vacuoles contributed to only a small extent to transport of chloride into the exuda...

Man has a limited capacity to absorb riboflavin (1-3) and thiamin (4, 5). The gastrointestinal absorption of these vitamins is describable by Michaelis-Menten type kinetics, characteristic of saturable, specialized absorption processes (6). Both vitamins are phosphorylated in the intestinal mucosa during absorption (7-9) and there is evidence suggesting that this process is the basic mechanism ...

The absorbed water from air into cellulose/ionic liquid gel dramatically increases the apparent ionic Seebeck coefficient. reason is hydrovoltaic voltage that depends on kinetics of absorption/desorption at different temperature.

Frequency-resolved femtosecond transient absorption spectra and kinetics measured by optical excitation of the second and first electronic transitions of the (8,3) single-walled carbon nanotube species reveal a unique mutual response between these transitions. Based on the analysis of the spectra, kinetics, and their distinct amplitude dependence on the pump intensity observed at these transiti...

The pharmacokinetic properties of drugs are closely related to their pharmacological efficacy. The kinetics of ivermectin are characterised, in general terms, by a slow absorption process, a broad distribution in the organism, low metabolism, and slow excretion. The kinetics vary according to the route of administration, formulation, animal species, body condition, age, and physiological status...

The ring-opening copolymerisation of a d -xylose 3,5-anyhydrosugar with isothiocyanates forms AB-type copolymers imidothiocarbonate linkages. Block copolymer synthesis, reaction kinetics, polymer degradation and metal absorption are explored.
