Ceramic systems of template explains and demonstrates how to prepare your camera-ready Ceramic systems of Bi2O3 and La-doped SrTiO3 (LST) solid mixtures La0.2Sr0.8TiO3–x%Bi2O3 (x = 0, 20, 25, 30, 35) are prepared and explored as possible anode materials for solid oxide fuel cells. It is shown that the conductivity of La0.2Sr0.8TiO3–x%Bi2O3 composites increases from 0.15 to 1.4 S cm−1 in 97%H2 +3%H2O at 800°C with increasing the content of Bi2O3. Electrochemical impedance spectra indicated that the addition of Bi2O3 into LST can significantly reduce the fuel cell’s polarization and refine the grains and increase the triple phase boundary, leading to a better performance of the fuel cells. The results suggest potential applications of LST–x%Bi2O3 composite as SOFC anode materials.

With rapid economic development in recent years, Yantai city's comprehensive strength has been significantly enhanced. Meanwhile, such problems as environmental and ecological protection has become increasingly prominent, which forms barriers preventing it from further growth in long run.The sustainable economic development vigor of Yantai has a strong practical significance. By building an evaluation index system with no quantitative treatment of data, this paper obtains economic development index of Yantai including social development, resource development, environmental development and comprehensive economic development index, and accompanied by analysis of its sustainable development. Finally, the author points out problems of economic development of Yantai, and puts forward related measures.

In order to study the interference and destructive effects of electromagnetic pulse for electronic systems, a test was done for an SCM system to check the irradiation effect of ESD EMP for it. According to the result of the test, under the effect of ESD EMP, the SCM would suffer multiple kinds of faults. This paper mainly introduces an exterior RAM effect test done for an SCM and the corresponding measures taken on the basis.

Using PEG-10000 and sodium citrate as stabilizer, and NaBH4 as reducer, a stable nanosilver (AgNPs) sol was prepared. In pH 6.6 phosphate buffer solution containing NaCl, the AgNPs were aggregated to large particles, which lead to resonance Rayleigh scattering (RRS) peak at 350 nm enhancement. Upon addition of cysteine, the peak decreased. The decreased value ΔI is linear to cysteine concentration in the range of 5.0×10-8-6.0×10-7 mol/L. Thus, a new RRS method was proposed for detection of cysteine.

In order to guide the planning of urban microclimate, the influencing variables of the heat island intensity (UII) of tall residential quarter in mountain city in spring and summer is quantitatively analyzed. Through experiments and simulations, 6 variables including wind speed(WS), green ratio(GR), impervious ratio(IR), average surface temperature(AST) , shadow ratio(SR), H / W were chosen and summarized as factors by dimension reduction in factors analysis; further, the dominant variables and factors in different time were confirmed through multiple linear regression analysis of the factors/ variables and UII. Results revealed that in the microclimate tests, it is appropriate to make factor analysis when the cumulative contribution rate of a factor is higher than 50%, and the significant correlated factor of UII is horizontal surface factor (HSF) in three fifths of the testing time in July. The variable analysis revealed that the significance of WS on UII is more in cloudy days than that in sunny days; the significance of SR is higher in summer than that in transition seasons and is most in 15:00, it demonstrates that optimal utilization of the building shadings is an effective way to improve the outdoor thermal environment in residential quarters.
