Gas exchange kinetics in elite runners.
Oxygen uptake (VO[2]) kinetics measured in the frequency domain are known to be faster in subjects of greater aerobic fitness (Essfeld et al. 1987). Carbon dioxide output (VCO[2] ) kinetics have been shown to be delayed following 6 months sprint and strength training in footballers (Fukuoka et al …

A 59-Cobalt NMR Investigation of the Hydrogen/Deuterium Exchange Kinetics in Cobalt(III) Complexes
Currently, the hydrogen/deuterium exchange kinetics in cobalt(III) complexes are being investigated. In the presence of deuterated solvents, (e.g. D2 0 and CH3CH20D) the amine hydrogens in the complexes are exchanged for deuteriums. For the hexaamminecobalt(III) ion, 19 isotopmers (H18D0 to HOD 18) …

Resting forearm blood-tissue lactate and gas exchange kinetics during supine leg exercise / by Peter Catcheside.
… during leg exercise, resting forearm lactate kinetics appear to resemble closely the blood-tissue exchange kinetics of inert gases that have been reported in many organs during inert gas inhalation. Two mathematical models of forearm lactate uptake were developed, and three series of …

Chromium and uranium isotopic exchange kinetics and isotope fractionation during oxidation of tetravalent uranium by dissolved oxygen
… of which are still poorly understood. Isotopic exchange and oxidation reactions are two types of them. High concentration, acidic-pH experiments were conducted to determine equilibrium fractionations between hexavalent Cr (Cr(VI)) and trivalent Cr (Cr(III)), and between hexavalent U (U(VI)) and …

Antimony isotopes as indicators of redox reactions in aqueous systems: fractionation during Sb(V) reduction by sulfide and isotope exchange kinetics between dissolved Sb(III) and Sb(V)
… environmentally relevant reactions. We use anion exchange resin and hydride generation MC-ICP-MS methods to obtain precise measurements of 123Sb/121Sb. The anion exchange method is also effective for separating Sb(III) from Sb(V). First, we find that isotopic exchange between aqueous Sb(V) and …

Controlling and understanding electro-chemo-mechanical properties of layered cuprate thin films
Surface exchange kinetics are a key indicator of performance for electrochemical devices including solid oxide fuel cells. Due to broad flexibility in dopant selection and concentration, mixed ionic-electronic conducting (MIEC) ABO₃ perovskite oxides have been extensively explored as model systems …

Thermodynamics and kinetics of ion-exchange in perchlorate-selective poly(vinylbenzyltrialkylammonium chloride) matrices
Perchlorate-selective ion-exchange fiber composites (IXFCs) based on an active resin-on-fiber architecture exhibit rapid exchange kinetics. Coatings consist of hydrophobic poly(vinylbenzyltrialkylammonium chloride) (PVBTC) matrices prepared by quaternization of a poly(vinylbenzyl chloride) …
