Evolution of the Pt layer deposited on MgO(001) by pulsed laser deposition as a function of the deposition parameters: A scanning tunneling microscopy and energy dispersive X-ray diffractometry/reflectometry study
Article Abstract:
A study is carried out on the morphology of Pt layers grown on MgO(001) by pulsed layer deposition as a function of the deposition temperature and deposition time with a combined use of ultrahigh vacuum scanning tunneling microscopy (STM-UHV) and energy dispersive X-ray diffractormetry/reflectometry (EDXD/EDXR). The results have shown that the combined use of the STM-UHV and EDXD/EDXR methods gives the morphological and structural information required for an oriented film growth, as required for magnetic recording application.

Qualitative and quantitative assessments of acid and base sites exposed on polycrystalline MgO surfaces: thermogravimetric, calorimetric, and in situ FTIR spectroscopic study
Article Abstract:
An investigation was conducted to know the impact of the parent material used to yield magnesia on its surface properties. The results showed the surface accessibility, basictiy, and base site reactivity to assume the following descending order, MgO-OX > MgO-HY > MgO-CA > MgO-PC. The results emphasized on the importance of implementing the combination of studies, if the nature, amount and strength of surface acid and base sites were to be exhaustively assessed.

Global optimization study of small (10 less than equal to N less than equal to 120) Pd clusters supported on MgO(100)
Article Abstract:
The result of a basin-hopping global optimization procedure applied to free and MgO-supported Pd clusters in the size range 10 less than equal to N less than equal to 120 are suggested. Pd - MgO interaction is modeled by an analytical function fitted to ab initio result, while Pd-Pd interactions are modeled by a semiempirical potential.
