Dynamics in complex systems: liquid crystals, biological water, supercooled water and enzymes
The origin of the glassy orientational dynamics, both single particle and collective, of nematogens near the isotropic-nematic transition has been addressed in several publications in recent years [5-7, 12]. In these ... -
Electron spectroscopic studies of the adsorption and reactivity of oxygen on transition metal surfaces covered with alkali and alkaline earth metals
Characteristic Cl(2p) and O(1s) peaks are seen by XPS attributable to distinct adsorbed chlorine and oxygen species on potassium and barium dosed Ag surfaces: a) There is selective stabilization of molecular dioxygen species ... -
Investgations of molecular interaction by photoelectron and electron energy loss spectrospies
Electronic structures of a variety of electron donor-acceptor complexes have been studied by employing ultraviolet (HeI) photoelectron spectroscopy. The systems studied are the complexes of BH? / AlCl?, GaCl? and SO? with ... -
Studies of surfaces by electron spectroscopy
All the organic molecules containing lone-pair orbitals adsorb molecularly (associatively) on copper at low temperatures (<100 K). b) It is possible to estimate the stabilization of the lone-pair orbitals due to chemisorption ... -
