Ca2+-containing porous gelatin-siloxane hybrids were prepared using sol-gel process, post-gelation soaking, and freeze-drying. The porosity and pore size of the hybrids could be well controlled by the freezing temperature ...

Cisplatin is one of the most effective cytotoxic agents against cancers. Its usage, however, is limited because of severe resistance and systemic toxicity. A formulation of cisplatin-loaded Au-Au2S nanoparticles (NPs) with ...

利用高分子网络凝胶法制备yAg:CE3+荧光粉,研究了煅烧温度、煅烧时间等对荧光粉的晶化过程、显微形貌及发光性能的影响。结果表明:高分子网络凝胶法可在1000℃煅烧温度下获得晶型完整的yAg:CE3+荧光粉;随着煅烧温度的升高晶粒尺寸增大,1000℃时平均粒径为50nM,在1300℃时平均粒径为120nM。随温度的升高和粒径的长大其相对发光强度也逐渐提高;随着保温时间的延长,晶粒变化不大,但发光强度逐渐提高,在400MIn时由于CE离子氧化而发生蓝移。

The phase equilibria in the binary Mn-Al system have been investigated over the temperature range 800 to 1200 degrees C and the composition range 50 to 80 at.% Mn using a combination of diffusion couple techniques, optical ...

Using a facing target sputtering equipment, Fe-Ti-N films were deposited on water-cooled and heated substrates under different nitrogen flow ratios, R(N-2). The composition, microstructure, and magnetic properties of the ...

A novel processing method was employed to produce (SrxPb1-x)TiO3 ceramics for high voltage capacitors, based on the computer simulation of a shell-core and two-phase mixed structural model proposed. Two different calcined ...

Silicon nitride ceramic has many advantages in high temperature structural applications such as high strength, creep resistance, and chemical stability. A disadvantage, however, has been its low fracture toughness, typically ...

In this article, nature derived collagen was mixed with chitosan and crosslinked by formaldehyde to form a homogeneous composite membrane. The microstructure of the composite was characterized by transmission electron ...
