Solid state chemical reaction is attributed to the chemical reaction performed at temperature which reactants are solid. In most solid state chemical reactions the reaction volume continually diminishes as the reactants become spatially separated by the products. As a result, the kinetics of solid state chemical reactions are limited by the rate at which reactant species are able to diffuse acr...

To obtain a water-soluble β-D-glucan derivative cleanly and conveniently, a highly efficient mechanochemical method, planetary ball milling, was used to phosphorylate β-D-glucan isolated from yeast Saccharomyces cerevisiae in solid state. Soluble β-D-glucan phosphate (GP) with a high degree of substitution (0.77-2.09) and an apparent PEAK molecular weight of 6.6-10.0 kDa was produced when β-D-g...

The structural stability of some nanostructured titanates was investigated in terms of their subsequent processing and possible applications. With the aim to investigate their mechanochemical stability, we applied high-energy ball milling and studied the resulting induced phase transitions. Hydrogen titanates with two different morphologies, microcrystals and nanotubes, were taken into consider...

For the polypentapeptide of elastin, (L-Val-L-Pro-Gly-L-Val-Gly)n, and appropriate analogs when suitably cross-linked, it has been previously demonstrated that development of elastomeric force at fixed length and length changes at fixed load occur as the result of an inverse temperature transition, with the temperature of the transition being inversely dependent on the hydrophobicity of the pol...

The influence of magnesium content on the mechanosynthesis of ZrB2–SiC–ZrC composite in Mg/ZrSiO4/B2O3/C mixture was investigated. Thermodynamic evaluations revealed that the amount of Mg played a main role, thereby; the overall reaction enthalpy and adiabatic temperature (Tad) changed by variation of magnesium content. According to differential thermal analysis (DTA) results, after 45min milli...

cauliflower-like nanostructure of cadmium oxide was synthesized by utilizing mechanochemical reaction followed calcination procedure for the first time. the design of experiment (doe) by taguchi method was used to study influence of the chosen factors and to consider optimum conditions of the experiments. the temperature of calcining, the duration of milling, the duration of calcining and react...

a facile mechanochemical-based method for synthesis of copper oxide (cuo) nanoparticles is here by introduced. for this purpose, copper hydroxide powder was synthesized through a facile solution method (cuso4 + 2 na(oh) → cu(oh)2 + na2so4) after which milling of as-prepared cu(oh)2 precursor and nacl resulted in the mechanochemical dehydration of cu(oh)2 and dispersion of cuo nanoparticles into...
