Piezoelectric relaxation has been studied on elongated poly(γ-methyl-L-glutamate) films with the α-helical molecular conformation. Relaxation processes are observed near 0 and 100°C. Each process has a dual character composed of relaxational and retardational frequency dependences. The low-temperature process is ascribed to thermal motion of side chains. The high-temperature process, discussed in relation to the dielectric relaxation, is attributed to the ionic dc conduction connected with the two-phase structure of crystalline regions and the electrode polarization. 相似文献

Unknotted ring defects in ordered media are classified in terms of the homotopy theory. It is also investigated what type of point defects will appear when a radius of the ring defect tends to zero. 相似文献

Summary Acetonitrilecopper(I) trifluoromethanesulfonate, CuTAN, reversibly forms liquid olefin complexes of composition olefin:CuTAN and olefin: (CuTAN)2. The complex formation constants of CuTAN with cyclohexene in anisole have been studied based on the observation that CuTAN exists as a dimer in anisole. 相似文献

We investigate the parity violating effect in helium and cesium atoms due to the exchange of a Z0-meson between atomic electrons. It is found that this effect is negligible for both atoms in comparison with the contribution from the electron-nucleus interactions, if we take the neutral-current coupling between electrons as predicted by the SU (2) × U (1) theory and sin2θW ≈ 0.3. 相似文献

Myelin figures were found to form at the main phase transition temperatures of several phospholipids for various ph values and Ca2+ concentrations. The optical observation of myelin figure formation provides a simple method of detecting the phase transition of phospholipids. 相似文献

Graft copolymerization of maleimide onto polyethylene and ethyl cellulose films by using its sublimation vapor was carried out under ultraviolet irradiation in the presence or absence of air; the effect of air or additives on the grafting reaction and on the nature of the grafted films was investigated. The extent of grafting gradually approached a fixed value, in spite of the continuous ultraviolet irradiation. Air retarded the grafting reaction but did not suppress the reaction nor alter the final extent of grafting. Benzoquinone showed no inhibiting effect on the grafting. The grafted polymaleimide was found to be amorphous, even though ultraviolet irradiation produces a highly crystalline homopolymer in the solid phase as well as in the liquid phase. The results were discussed in comparison with those of the vapor-phase grafting under γ-ray irradiation; the reaction is attributed to the vapor–crystal equilibrium of monomer and to the formation of short-chain crosslinks. 相似文献

Thermal treatment of 2, 5-bis(2-thioanisidino)-3, 6-dichloro-1, 4-benzoquinone and its selenium derivative brought about demethylchlorination to give triphenodithiazinequinone and triphenodiselenazinequinone, respectively. 相似文献
