Trimeric porphyrin H6TP as well as its binuclear Cu2H2TP and trinuclear Cu3TP copper complexes have been prepared. Kinetic features of H6TP and Cu2H2TP complexes formation with copper(II) acetate in acetic acid as well as dissociation kinetics of Cu2H2TP and Cu3TP in acetic acid medium in the presence of sulfuric acid have been studied. 相似文献

The elastoplastic properties (elastic modulus, amplitude-independent damping ratio, microplastic flow stress) of a Ti-26Nb-7Mo-12Zr titanium β alloy are determined using an acoustic resonance method. The effect of the strain during thermomechanical treatment on the structural features of the micro-crystalline alloy and, hence, its elastoplastic properties is analyzed. 相似文献
