Sr(Zr1-xYx)O3-δ-TiO2异质结型复合光催化剂的可见光催化活性
放射性核素治疗皮肤病是核素在治疗方面应用的一个重要分支。利用放射性核素90Sr-90Y敷贴器敷贴β射线治疗部分皮肤病,具有疗效可靠、方法简便、无痛苦、洁净安全、不易复发等优点。 基本原理:90Sr衰变发射低能β射线,半衰期为28.5年。β-粒子的最大能量为0.546MeV,平均能量为0.2MeV,在组织内的射程仅为2～3mm。但其...
电解质钙钛矿相粉体粒度稀土采用Pechini法合成了Sr(Ce0.6 Zr0.4)1-x Yx O3(SCZY,x=0.10,0.15,0.20)电解质粉体,将所制粉体模压成型后在1450℃煅烧10 h得到固体电解质.采用XRD研究掺杂量和煅烧温度对粉体相纯度的影响,通过SEM观察粉体和电解质的微观结构,用电化学阻抗谱法测量电解质的电性能.结果表明:1000℃...
得益于车身尺寸与后悬长度的优势,Artone SR行李厢的进深确实非常大,同时它溜背的造型也并没有对于分隔板空间有太多影响,实用性与中型SUV也几乎并没有太大差别。 动力方面,大众Arteon SR搭载了EA888-DUN的2.0T发动机,最大功率190马力,峰值扭矩320N·m,相当于330TSI的标准,匹配7速双离合变速箱。这套动力确实是非...
We computed the optical bandgaps of the CH3NH3Pb(1-x)Y(x)I3 (Y=Bi, x = 0.00, 0.125) and CH3NH3Pb(1-x)Y(x)I3 (Y=Ca, Sr, x = 0.125, 0.250) perovskite crystal structures using optical arguments such as the imaginary part of the dielectric function ε2(ω), absorption coefficient...
New mixed conducting oxides with the composition of Sr1−xYxCo1−yYyO3−δ (x = 0.0–0.8, y = 0.0–0.1) were exploited and synthesized. The resulted materials were investigated by X-ray diffraction, four-probe dc conductivity, temperature-programmed desorption characterization, and oxygen per...

The systematic study of the solid solution Pr12 − xYxSr12MnO3 shows the coexistence of two types of CMR effect on the same sample associated with a transition from an antiferromagnetic semiconducting to a ferromagnetic metallic state (at Tco) and then to a paramagnetic semiconducting state (at...
Growth and superconductivity of Bi2Sr2Ca1−xYxCu2O8+δ single crystals in the Tc optimum region Bi 2 Sr 2 Ca 1− x Y x Cu 2 O 8+δ single crystals with low Y concentrations were grown by a self-flux method and characterized structurally by electron microscopy. Furthermore, their ...
