Growth, structural, spectral and high-power continuous-wave laser operation of Yb_(0.11)Gd_(0.89)COB
A Yb_(0.11)Gd_(0.89)Ca_4O(BO_3)_3 crystal with new composition was grown by the Czochralski method. The crystal structure was measured and analyzed. The unit-ce

The self-assembly of block copolymer in solution are constantly expanding,in part because of the increasing degree of control over the size,morphology and funct
Photoelectrocatalytic activity of an ordered and vertically aligned TiO_2 nanorod array/BDD heteroju
Rutile TiO_2 nanorod(TiNR) arrays were fabricated on a boron-doped diamond(BDD) substrate by a simple hydrothermal synthesis method. A fluorine-doped tin oxide(
采用扫描电镜、傅里叶红外光谱和X射线衍射法研究了不同干燥方式对纤维形态及其超分子结构的影响.结果表明:与自然风干条件相比,强制干燥使得纤维变得更加光滑、挺硬,呈现扁平状,降低了纤维的润胀能力.不同的干燥方式不会改变纤维的晶型结构,但对不同模式的氢键的含量却产生了明显影响.与自然风干的纤维相比,强制干燥后纤维分子间氢键O(6)H…O(3′)含量明显增加了19.41％,而分子内氢键O(2)H…O(6)
