We present the results of a systematic study of the temperature-dependent resistivity and of T-c of a single crystal MgB2 sample as a function of point defect concentration. We have found linear, albeit weak, correlation between the decreasing superconduct ...
With four site: Catalytic olefin hydrogenation is observed with palladium complexes when the N-heterocyclic carbene ligand is changed from the normal C2- to the unusual C4-bonding mode (see scheme). In a cis coordinating framework, the electron density at ...
We have calculated the atomistic mechanism for the HfO2 atomic layer deposition (ALD) using Hf(NEtMe)(4) and H2O precursors using density functional theory. On hydroxylated Si surface, our results show overall Hf(NEtMe)(4) half-reaction is exothermic by 1. ...
The aim of this study is to analyze the use of Ag-doped activated carbon aerogels for bromide and iodide removal from drinking water and to study how the activation of Ag-doped aerogels affects their behavior. It has been observed that the carbonization tr ...
The efficiency of Co(II)-, Mn(II)-, and Ti(IV)-doped carbon aerogels for the transformation of ozone into center dot OH radicals was investigated. The carbon aerogels had a markedly acid surface character (pH(PZC)congruent to 3-4) with very high surface ox ...
This thesis addresses the link between capillarity parameters, i.e. surface tension and contact angle, and the infiltration of porous preforms with molten metal by pressure infiltration The method used is to conduct pressure infiltration experiments of sel ...
This paper presents a feasibility study on the development of a gas preconcentrator based on micro-reactor technology on silicon. The objectives are to select a gas adsorbent material, to produce a silicon micro-reactor with an integrated heater, and final ...
The present thesis work deals with the investigation of the heterogeneous reactions involving nitrate radical (NO3), dinitrogen pentoxide (N2O5) and ozone (O3) on surrogates of atmospheric mineral dust particles characteristic of the troposphere. An additi ...
Density functional theory is employed to investigate atomic layer deposition mechanism of HfO2, on Ge(I 0 0)-2 x I surface. Both the HfCl4 and H2O half-reactions proceed through an analogous trapping-mediated mechanism. The neighboring hydroxyl in the reac ...
Cluster calculations employing hybrid density functional theory have been carried out to examine the initial surface reactions in atomic layer deposition (ALD) of TiN thin films on the SiO2 surface using TiCl4 and NH3 as precursors. The potential energy su ...
