چکیده

A modern industrial route for the manufacture of methyl methacrylate involves the reaction of methyl propanoate and formaldehyde over a silica-supported Cs catalyst. Although the process has been successfully commercialised, little is known about the surface interactions responsible for the forward chemistry. This work concentrates upon the interaction of methyl propanoate over a representative silica. A combination of infrared spectroscopy, inelastic neutron scattering, DFT calculations, X-ray diffraction and temperature-programmed desorption is used to deduce how the ester interacts with the silica surface.

Hydration of cement: The application of quasielastic and inelastic neutron scattering

Quasielastic and inelastic neutron scattering have been highlighted as excellent tools for studying the hydration of cement components. Here, the complimentary application of inelastic and time-resolved quasielastic neutron scattering to investigate the reaction kinetics during the crucial first 24 h of hydration will be highlighted. Some recent results include the interaction of tricalcium and...

Neutron scattering study of the vibrations in vitreous silica and germania.

The incoherent approximation for the determination of the vibrational density of states of glasses from inelastic neutron or x-ray scattering data is extended to treat the coherent scattering. The method is applied to new room temperature measurements of vitreous silica and germania on the thermal time-of-flight spectrometer IN4 at the High Flux Reactor in Grenoble. The inelastic dynamic struct...

روش خودسازگار در محاسبه نسبت با استفاده از تابع ساختار و نسبت EMC هسته‌های He3 و H3

By using the convolution formalism which consists of Fermi motion and binding effect, we investigate the deep inelastic electron scattering from A=3 mirror in the deep-valence region. The initial valence quark input is taken from the GRVs (Gluck, Reya and Vogt) fitting procedure and the next-to-leading order QCD evolution on FP2 (x,Q2) which gives very good fit to the available data in the (x,Q...

برهمکنش الکترون - فونون در ابررساناهای دمای بالا

  We explore the important role of the strong electron-phonon interaction in high temperature superconductivity through the study of the results of some important experiments, such as inelastic neutron and X-ray scattering, angle resolved photoemission spectroscopy, and isotope effects. We also present our computational results of the eigenvalues and eigenvectors of the Ag Raman modes, and the ...

From colloidal-silica sols to aerogels and xerogels

By destabilization of quasi-monodisperse silica sols, fractal clusters can be obtained. Solvent evacuation gives a porous solid with fractal structure. Structural investigations of these colloidal aerogels by small-angle neutron scattering are presented, and compared to similar observations in concentrated sols and xerogels. An investigation of the vibrational modes of these materials by inelas...
