Hereon, four different crystal structure of absorbents were selected to illustrate why the crystal structures and surface properties of absorbents were of great importance for the phosphate adsorption. The results showed that MgO/KBC with higher combination degree between MgO and KBC could change the ...
The crystal structure was accurately determined by X-ray diffraction analysis with a final residual R = 0.044. The structure, which is based upon a closest packed oxygen anion array, (ABACBC)n, involves a unique stacking of an olivine-type layer with a substituted MgO-type layer....

The structure of Au-implanted MgO, SrTiO3 and LiNbO3 oxides has been studied by X-ray diffraction, optical absorption spectroscopy and Rutherford backscattering/channeling technique. The surface layers of SrTiO3 and LiNbO3 crystals are amorphised by the Au implantation, while the surface layer of ...
Crystal Structure (redirected fromCrystal structures) Medical The arrangement of atoms, ions, or molecules in a crystal. Crystals are solids having, in all three dimensions of space, a regular repeating internal unit of structure. Crystals have been studied using x-rays, which excite signals from...

铌酸锂振动模式非谐相互作用降温过程抗光折变能力掺镁非线性光学性能哈尔滨工业大学We have investigated the structure of the crystal LiNbO3: MgO at both low temperature and room temperature. The results showed that the crystal structure had changed little after doping of Mg2+. At room temperature the ...
The Mg/MoS2composites were prepared by ball milling under argon atmosphere, and the effect of MoS2on the crystal structure and hydrogen storage properties of Mg was investigated. It is found that 10 wt% of MoS2is sufficient to prevent particle aggregation and cold welding during the milling proce...
Growth, surface morphology, and electrical resistivity of fully strained substoichiometric epitaxial TiN x (0.67⩽x layers on MgO(001) Abstract We have grownsingle-crystal NaCl-structure δ- TiN x layers with x ranging from 0.67 to 1.00 on MgO(001) at 700 °C by ultra-high-vacuum react...
Compound 1 exhibits a 3D supramolecular framework based on weak interactions between bisupported Dawson structure P 2 W 18 O 62 6 units and copper-complex fragments. With the aid of π–π stacking and hydrogen bonding interactions, a 1D supramolecular framework accommodating polyoxometalate (POM) ...
