FeO3 type (where A = Lu, Yb, Tm, Er, Ho, Dy, Tb, Gb, Eu, Sm, Nd, Pr, La; 0.05 ≤ x ≤ 0.20; Δx = 0.05) were prepared. Spectra of the real part of electrical conductivity were studied within the range 10−4–10−6 Hz. The dependence of the samples’ thermal stability and electrical conductivity on the size of the substituting ions was
established. 相似文献

Morin immobilized on cellulose matrices was used as a reagent for determining Al, Be, and Zr(IV) by the length of the fluorescent
zone on a test strip after its contact with the test solution and by the fluorescence intensity of the reaction zone of the
indicator matrix after passing the test solution through it. A test procedure was developed for determining 0.2–200 mg/L Al
in potable water using paper test strips sealed in a polymer film. Test procedures were developed for determining 0.0001–1
mg/L Al and 0.00001–0.1 mg/L Be in river water by the intensity of the fluorescent zone on the indicator viscose fabric after
passing 100 mL of the test solution through it, using a test facility. The time of analysis was 15–20 min. The relative standard
deviation did not exceed 40% in the former case and 60% in the latter case. 相似文献

Conclusions In aluminum-chromium catalysts promoted by potassium and rare-earth oxides, used in the synthesis of 2-methylthiophene by heterocyclization of n-pentane with hydrogen sulfide, there are present low-valence cations of chromium and the rare-earth that enter into the active centers of the catalysts.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 782–784, April, 1986. 相似文献

The switching and memory effects in composite films based on conducting polymers [poly(phenylenevinylene), thiophene, and carbazole derivatives] and inorganic nanoparticles (ZnO, Si) are investigated. It is established that the introduction of inorganic nanoparticles (ZnO, Si) exhibiting strong acceptor properties into polymer materials leads to the appearance of memory effects, which manifest themselves in the transition of the polymer from a low-conductivity state to a high-conductivity state. For a number of composites, this transition is accompanied by the formation of a region with a negative differential resistance and a hysteresis in the current-voltage characteristics. It is demonstrated that the observed effects are determined by the mechanism of charge carrier transfer in the composite. In particular, the main mechanism of transport in films based on thiophene derivatives is associated with electrical conduction due to the tunneling of charge carriers between conducting regions embedded in a nonconducting matrix, whereas the dominant mechanism of transport in “polymer-semiconductor nanoparticle” composite films is hopping conduction, which is responsible for the effects observed in these objects. 相似文献
