Thorium oxide dissolution kinetics for hydroxide and carbonate complexation
… behavior of thorium oxide was investigated. The kinetics of crystalline thorium oxide dissolution were studied under argon and argon/10% CO2 over a broad pH range in 0.1 M ionic strength NaC1O4 solution. Samples were analyzed for thorium concentration using ICP-AES, ICP-MS, and NAA. Data was fit …

Development of a Kinetic Model to Investigate the Effect of Compositional Variation and a Processing Condition on the Solid-State Degradation of Gabapentin
… excipients and compaction pressure will accelerate the solid-state degradation of gabapentin, increasing the kinetic rate constant for lactam formation. To test the hypotheses, binary mixtures and compacts of gabapentin with different excipients were prepared and stored under accelerated study …

Phase Transitions and the Effect of External Fields in Thermotropic Main Chain Liquid Crystal Systems
… a magnetic field were found to increase both the rate and ultimate degree of molecular orientation relative to samples exposed to magnetic fields in contact with featureless surfaces. TSD spectra of one of the polymers previously crystallized from the liquid crystalline melt under the influence of …

Thermal Degradation Studies of Polycarbonate
… is general. This t parameter is a product of the kinetic rate constant, k, found from isothermal kinetics, and the time of degradation, t. Elucidation of t has been linked to measurement of the molecular weight distribution which in turn can be related to various properties to yield predictive …

Passive detection of phosphorus in agricultural drainage waters using reactive hybrid anion exchange resins
… were more selective for phosphate against nitrate and sulfate. Hybrid resins also had high adsorption capacity for DRP (6.33-19.84 mg/g) and high kinetic performance (second-order kinetic rate constant at 0.035-0.127 g/(mg·min)). Furthermore, the hybrid resins was stable and had irreversible …

Earth Abundant Catalysts for Water Electrolysis at Low Overpotentials
… microscopy (SI-SECM), we measured the kinetic rate constant(s) of the active sites on crystalline Ni0.8:Fe0.2 and amorphous Ni0.8:Fe0.2. We found that the crystalline Ni0.8:Fe0.2, synthesized at high temperatures, had both ”fast” and ”slow” sites with a rate constant of 1.3 s-1 and 0.05 …
