316不锈钢热照射疲劳中的硬化行为

研究了316不锈钢在333—573K不同疲劳温度及不同应变振幅下热照射疲劳中的硬化行为,结果表明:在振幅E=1.17×10^(-4)下,热照射在333—573K温区内疲劳过程中,有大小几乎相同的软化产生;在(2.05—4.39)×10^(-4)应变振幅范围内,在333—503K温区内,热照射疲劳过程中出现软化,而在503—573K温区内,热照射疲劳过程中软化转变为硬化,此种由热照射引发的硬化所出现的疲劳温度随疲劳应变振幅的加大而提高。

Temperature Dependence of Thermal Emission Rate in Cr: GaAs

The new method of measuring the ratio of thermal emission rate to the photoexcitation constant is presented. The temperature dependence of the ratio for Cr:GaAs is calculated by using the previously published data of two-wave mixing. Results show that the calculating data and previous phenomenological theoretic ones coincide with each other very well.

Gas-phase Thermolysis of 1,2,3-triazole and 1,2,3-triazine Derivatives

On the other hand, direct condensation and pyrolysis of naphtho[1,8-de][1,2,3]triazine with ethylisocyanate, phenylisocyanate and their isothiocayanates, benzoylisothiocyanate and thiourea at 150-160 ℃ or under microwaves irradiation produced the corresponding naphthopyrimidin-2-one derivatives.

Insufficient thermalization effects on determining fission-track ages

Fission-Track Dating (FTD) has been developed as a useful technique for geological studies. Parent elements are measured by counting 235 U tracks induced by thermal neutrons. If insufficient thermalization occurs, fission of 238 U and 232 Th will be induced, and further measurement error will be introduced. Therefore, whether the neutrons are well thermalized or not will affect the FTD results. Due to requirement of safe operation, the 101 reactor was terminated in 2007. By using the 492 reactor as the new thermal neutron reactor, our present paper will attempt to study the feasibility and the potential influence on FTD. By irradiating monitor glass SRM612 and CN5 in pairs, we will study the thermalization situation of the 492 reactor. Irradiated data show that thermal neutrons are not evenly distributed either in horizontal or in vertical dimension. Especially, horizontal heterogeneity is obvious. But we discovered that proper irradiation position in the reactor can meet the requirement of FTD. Under the current irradiation condition, we calculated and assessed the insufficient thermalization effects on determining fission-track ages. We found that the difference between the 232 Th/ 238 U ratios of samples and standards is the main factor to the experiment results. The results will not be affected if the 232 Th/ 238 U value of samples is equal to the standard samples. However, if the 232 Th/ 238 U ratio is larger than that of the standards, the results will be smaller than actual ages. Comparatively, the ages will be more than expected if the 232 Th/ 238 U ratio is less. Therefore, to reduce the irradiation error, we suggest either locating the position of irradiation strictly, or minimizing the influence of lateral heterogeneity by reducing the amount of each sample package. Additionally, accuracy of the experimental results can be improved by increasing standard samples to adjust ζ value and using the monitor of standard glass SRM612 and CN5 together.

Quantum dot-sensitized solar cells employing Pt/C_(60) counter electrode provide an efficiency exceeding 2%

A microporous platinum/fullerenes (Pt/C 60) counter electrode was prepared by using a facile rapid thermal decomposition method,and the quantum-dot sensitized solar cell (QDSSC) of Pt/C 60-TiO 2-CdS-ZnS and Pt/C 60-TiO 2-CdTe-ZnS was fabrication.The technique forms a good contact between QDs and TiO 2 films.The photovoltaic performances of the as-prepared cells were investigated.The QDSSCs with Pt/C 60 counter electrode show high power conversion efficiency of 1.90% and 2.06%,respectively (under irradiation of a simulated solar light with an intensity of 100 mW cm 2),which is comparable to the one fabricated using conventional Pt electrode.
