l13Cd NMR measurements in two Ag-Cd samples cycled between room temperature and temperatures below M, are presented. The growth curve of the martensite on cooling presents a discontinuity in the cycling temperature region. It is shown that the method of analysis of the NMR data recently developed by us [Phys.Rev.B 46, 10563 (1992)], allows to detect subtle memory effects and the absolute determ...

We study analytically the effect of temperature cyclings in mean-field spinglasses. In accordance with real experiments, we obtain a strong reinitialization of the dynamics on decreasing the temperature combined with memory effects when the original high temperature is restored. The same calculation applied to meanfield models of structural glasses shows no such reinitialization, again in accor...

The possibility of producing chemical fuel (hydrogen) from the solar-thermal energy input using an isothermal cycling strategy is explored. The canonical thermochemical reactive oxide, ceria, is reduced under high temperature and inert sweep gas, and in the second step oxidized by H2O at the same temperature. The process takes advantage of the oxygen chemical potential difference between the in...

Tin platings on component finishes may grow whiskers under certain conditions, which may cause failures in electronic equipment. Although the thermal mismatch of tin and FeNi42 is well known and tin whiskers have been reported after thermal cycling of this material combination, no systematic investigation on the effects of thermal cycling is available. In this paper we describe the influence of...
