Solid State Inorganic Chemistry
We aim to understand and exploit the factors (strain, composition, band structure etc.) that determine structure and function in the crystalline solid state. Our interest is in the balance between local crystal chemistry, strain and longer range order in a wide range of compositionally and/or displacively flexible crystalline solids. The principal experimental research tools used are solid stat...
متن کاملSelf-Diffusion in Solid Argon
The self-ditlusion coefficient D = De exp( —() /RT) for solid argon has been measured in thin specimens of large grain size by a tracer technique. The results, Dp=0.2+p. 14 '3~ cm~ sec ' and Q =3600+150 cal mole ', are lower than those obtained in previous investigations. The value of Q agrees reasonably well with a twobody absolute-rate calculation for vacancy migration, but not with calculati...
متن کاملTheoretical studies of solid–solid interfaces
We review recent progresses in the theoretical studies on the structural, cohesive, mechanic and thermodynamic aspects of interfaces in solids. The technological developments for these studies are reviewed at first. In the next, we summarize the new achievements in the studies on the cohesive and structural properties of metal/metal, ceramic/metal and semiconductor interfaces by ab initio compu...
متن کاملSolid-State Diffusion and NMR
Diffusion in solids, which requires the presence of crystal defects or disorder, has both microscopic and macroscopic aspects. Nuclear magnetic resonance techniques provide access to microscopic diffusion parameters like atomic jump rates and activation energies as well as to the tracer diffusion coefficient for macroscopic transport. Microscopic NMR methods include spin-lattice relaxation spec...
متن کاملKinetics inversion of chloro-olefine in the solid acid system
The reaction kinetics of the isomerization 3,4-dichlorobutene-1 to 1,4-dichlorobutene-2 was investigated by using gas-liquid chromatography method in the presence of Fe2O3/MgO as solid catalyst in the temperature range 25-55°C. Fe2O3/MgO has been prepared by the support saturation method, tested in the isomerization of 3, 4-dichlorobutene-1 into 1, 4-dichlorobutene-2. This catalyst shows a high...
