The catalytic hydrolysis of dimethyl ether (DME) over H-ZSM-5 was studied by experimental and theoretical studies. We observed from the pack-bed reactor that this reaction yields methanol as product at low temperature (<;300°C), but produces other carbon-containing species at higher temperature (>;300°C). However, these observations cannot give the details of the reaction mechanisms. To clarify...
The effect of solution temperature and the determination of the kinetic parameters of methylene blue (MB) adsorption onto cereal chaff were performed to understand the adsorption mechanism. The pseudo-second order kinetic model was fitted to the experimental data and found it was good to predict the adsorption behavior using nonlinear regressive method, suggesting that the mechanism may be a chemisorption...
Superfill (bottom-up) phenomena relevant for Damascene processing typically rely on the time-dependent interplay of various organic and inorganic additives with both the metallic copper surface and with cuprous ions as intermediates of the copper electro-reduction in the near-surface regime. In-situ STM, in-situ SXRD (Surface X-Ray Diffraction) measurements combined with DFT calculations provide new...
