A modified next reaction method for simulating chemical systems with time dependent propensities and delays

Glycation reactions, such as those seen in late diabetes, can be mimicked in purely chemical systems. The glycation is time-dependent, and in in vitro systems it may continue for days. Ascorbate seems to enhance the reactions. The reactions are associated with free-radical formation through transformation of an Amadori product to (deoxy-)glycoson, catalysed by heavy metals. Ascorbate enhances the reaction by a factor of 5–10 compared with in vitro systems without ascorbate. In vitro systems containing bovine serum albumin retard the formation of free-radicals, because of the formation of advanced glycation products.

High-T c cuprates of "Bi-2223" bulk doped with Cr 0≤ x≤ 0.10 were prepared by the conventional solid state reaction method. The samples were investigated by electrical resistivity, Hall effect, Nernst effect, ac susceptibility and thermopower measurements in mixed and normal states. The transport coefficients depend strongly on the Cr contents in the samples. The temperature dependence nH(T) and inverse Hall mobility [Formula: see text] show an anomaly at a temperature around 240 K. These anomalies are discussed in the framework of phase separation theory. The experimental data in the mixed state are in agreement with the predictions of the time-dependent Ginsburg–Landau theory.
