چکیده

The properties of the interfacial water monolayer on MgO(001) during growth of multilayer ice and, in particular, the dewetting of crystalline ice on MgO(001) are revealed by vibrational sum frequency generation and infrared reflection absorption spectroscopy.

Epitaxial TiN(001) wetting layer for growth of thin single-crystal Cu(001)

Single-crystal Cu(001) layers, 4-1400 nm thick, were deposited on MgO(001) with and without a 2.5-nm-thick TiN(001) buffer layer. X-ray diffraction and reflection indicate that the TiN(001) surface suppresses Cu-dewetting, yielding a 4 lower defect density and a 9 smaller surface roughness than if grown on MgO(001) at 25 C. In situ and low temperature electron transport measurements indicate th...

Enhanced stability of gold clusters supported on hydroxylated MgO(001) surfaces.

The influence of surface hydroxylation on nucleation and sintering of gold nanoparticles was studied by comparison of Au deposition and thermal sintering on ideally terminated MgO(001) and hydroxylated MgO thin films, respectively. A combination of different spectroscopic techniques (TDS, XPS, IRAS) allows to establish a correlation between the degree of surface hydroxylation and the stability ...

Good performance of the M06 family of hybrid meta generalized gradient approximation density functionals on a difficult case: CO adsorption on MgO(001).

The adsorption of CO on Mg(001) constitutes a challenge for current density functional approximations because of its weak interaction character. In the present work we show that the M06-2X and M06-HF exchange-correlation functionals are the first ones to provide a simultaneously satisfactory description of adsorbate geometry, vibrational frequency shift, and adsorption energy of CO on MgO(001)....

Lattice Dynamics Simulation of Ionic Crystal Surfaces: I.~Criteria for Vibrational Mode Localisation and Surface Modes

A simple function, called attenuation parameter, is presented that can be used to extract quantitative information on the degree of localisation of normal modes at locations of arbitrary dimensionality from eigenvector components calculated in lattice dynamics simulations. Normal modes are identified as localised if their attenuation parameter values exceed a certain threshold value. As example...

Fourier Transform Infra Red Spectroscopic Studies on Epilepsy, Migraine and Paralysis

In the present paper, we have studied immunglobulin (IgG) of epileptic children, migraineous and paralytic patients.  We have compared our results with normal healthy controls. We found that the bands ranges from 1151.94 to 1168.28 cm-1 due to phospholipids (P-O-C ) group appear in some of the migraineous and paralytic patients only. These bands are absent in normal and epileptic patients. The ...
