Gd3+-,Pr3+-or Sm3+-doped Co-Zn(Co0.5Zn0.5Fe2 O4)magnetic ferrites(i.e.,Co0.5Zn0.5Gd0.1Fe1.9O4,Co0.5Zn0.5Pr0.1Fe1.9O4 and Co0.5Zn0.5Sm0.1Fe1.9O4)were prepared using a facile sol-gel approach,and the structure,surface morphology and chemical composition of the products were studied by means of scanning electron microscopy(SEM),energy dispersive X-ray analysis(EDX),X-ray diffraction(XRD),UVvisible diffuse reflectance spectroscopy(DRS),photoluminescence(PL)spectroscopy,Fourier transform infrared spectroscopy(FT-IR)and vibrating sample magnetometer(VSM)*** patterns show the Co-Zn product is composed of cubic spinel phases with few impurities or secondary phases,and the average crystallite sizes of the samples are determined to be approximately^51—80,~99—181,~68—103 and^83—133 *** the coercivity and remnant and saturation magnetizations,evaluated by vibrating sample magnetometer(VSM),are found to increase linearly with the incorporation of Gd3+,Pr3+and Sm3+in the product *** CO1-xZnxFe2-yRyO4 photocatalyst sample is found to display a red shift in its absorption,and exhibits outstanding photocatalytic effects in the degradation of MO under ultraviolet(UV)*** is attributed to the reduction of the band gap of cobalt-zinc ferrite due to the presence of rare earth *** in vitro evaluations of the cytotoxic effects of the synthesized nanoparticles were performed on a HeLa cell line.

“不适宜”即“未完成”为了应对财政层面对项目的限制,我们采用了一种简朴、坦率的构造。精简掉了所有“不适宜”的多余修饰和装饰层。“受压制”即“无拘束”对于女孤,在像汉瑟尔这样由男性主导的宗教城市中,很难行使自主选择生活方式的权利。基于对现状的判断,庇护所采用了内向型的建构来回应对少女安保问题的关注。我们利用阳台外侧手动操作的帷幔,将项目的立面转变为一个可以根据女孩的需求及意愿关闭、或面向城市开启的媒介。女孩在学习如何操作这座建筑的同时,也在生活中行使着自己有限的权利。
