TL;DR: In this paper, the kinetics of crystal nucleation in Na 2 O · 2SiO 2 have been determined over the range of undercoolings between 173 and 373°C, and the results are in good agreement with predictions of the theory of homogeneous nucleation, even in the preexponential factor.

TL;DR: In this article, the effect of poly(N-isopropylacrylamide) (PNIPA) with ionic and nonionic surfactants was investigated by light scattering methods at temperatures 15-45°C.
Abstract: Solutions of poly(N-isopropylacrylamide) (PNIPA) with ionic and nonionic surfactants were investigated by light scattering methods at temperatures 15–45 °C. In contrast to previous studies, where surfactants were used in excess, lower concentrations of surfactants were used. The formation of well-defined nanoparticles of PNIPA was observed on heating above the lower critical solution temperature. The effect of PNIPA and surfactant concentrations, and molecular weight of PNIPA on nanoparticle parameters and on the phase transition temperature of PNIPA solutions were investigated. An interpretation based on stabilization of PNIPA nuclei by surfactants was suggested.

TL;DR: In this article, the interaction of an unsupported silver catalyst which had been pretreated by hydrogen at various temperatures with oxygen at 210°C has been studied using Temperature Programmed Reduction (TPR) over a temperature range up to 900°C.

TL;DR: A general theory of cluster growth and Ostwald ripening under the influence of elastic strain evolving as the result of cluster formation and growth is developed in this article, which is applied to an interpretation of experimental results on segregation processes in glass-forming melts, showing a quite different asymptotic behavior in the stage of Ostwald ripping as compared with the Lifshitz-Slyozov power laws.
