The dielectric tunability of Fe-doped Pb0.3Sr0.7TiO3 thin films prepared by sol-gel method Xiaohua Sun1, 2, Shuang Hou2, Xiuleng Li2, Tianyou Peng1, Xing-zhong Zhao1a 1 School of Physics, College of Chemistry and Molecular Science, Wuhan University, Wuhan 430072, China. 2 School of Mechanical and Material Engineering, China Three Gorges University, Yichang 443002, China.
Introduction In recent years, ferroelectric materials have attracted great interest for their widely potential applications, including dynamic random access memories, microwave filters, infrared detectors and dielectric phase shifters [H1H, H2H].
The Fe doped PST precursor solutions were synthesized using lead acetate tri-hydrate Pb(CH3COO)2·3H2O, strontium acetate semi-hydrate Sr(CH3COO)2·1/2H2O, ferric nitrate Fe(NO3)3·9H2O and titanium butoxide Ti(OC4H9)4 as the starting materials.

L. saponin using microwave-surfactant Tang Kai1,a*, Yan Jie1,b,Huang Xin1,c (1 Material and Chemical Engineering Department, Sichuan University of Science & Engineering, Zigong Sichuan, China, 643000) a 496739055@qq.com,b yanjie0813@gmail.com,c 457092701@qq.com Keywords: Momordica Charantia.L; saponin; microwave; surfactant; orthogonal experiment Abstract: In this paper, microwave-surfactant assisted extraction of saponin from Momordica Charantia.L was studied.
L. saponins, so that provide basis for further industrial production. 2 Material and method 2.1 Material and instrument 2.1.1 Material and reagents Momordica Charantia.
They were all analytically pure and purchased from ChengDu Kelong Chemical Reagent Company. 2.2 Instrument and Equipment A MDS-10 microwave extraction instrument was purchased from Shanghai Sineo Microwave Chemistry Science and Technology Ltd., China.
L. residues are erosion apparently, which is unfavorable to the separation of saponin molecules from the materials. 3.2.3 The effects of solid-liquid ratio on the extraction rate of Momordica Charantia.

What’s more, the material properties are as follows, modulus of elasticity E=1011Pa, density ρ=1200kg/m, Poisson's ratio μ=0.25.
In order to accommodate the flapping wing aerodynamic force and not to weaken the aerodynamic effect, two polymer rods of the prototype’s wings are placed to support the wing surface which is made of soft film materials shown in Fig. 7 (b).

The contamination hazard from ambient air mainly appears in the human health, agriculture, forestry and materials.
Based on the relations between concentration and sources and the loss calculation for pollution hazards, a model for regional atmospheric environmental capacity can be established with largest allowed emission(least abatement cost) and least loss by contamination (herewith only concerning the losses to human health, agriculture and forestry by the air pollution without the loss to materials).
