(MM) and spray drying process.The surface morphology and crystal structure were characterized by using FESEM,XRD,TEM,et al.The absorption hydrogen amount was 3.24 % within 60 min at the temperature of 250 ℃ under the 3.0 MPa H2.Simultaneously,the on-set temperature of hydrogen desorption of...
The effects ofmethyl groupin 3 methyl 4 nitropyridine N oxide (POM) on the second order nonlinear optical properties and the crystal structure were studied,and a semiempirical analysis on the electronic and microscopic properties was carried out. ...
第一作者:徐化明,男,22岁,硕士研究生;研究方向:碳纳米管。碳纳米管于1991年被发现[1],管径大小为纳米 级,其管壁结构类似石墨,导电性好,比表面积大,具有优异的力学,电学,热学性能。由于其具有独特的性能,碳纳米管的应用研究一直是科学家们关注的焦点,其中碳纳米管复合材料研究被认为是最有...
the lattice defects in the crystal structure caused the lattice displacement, and the system temperature increased at the same time. At this stage, the free energy of lignocellulose surface increased. Then, the intrant Ca and PMMA were adhered to the NLC surface by hydrogen bonding and electrosta...
