Density functional theory study of initial stage of ZrO2 atomic layer deposition on Ge/Si(100)-(2×1) surface

The reaction mechanisms of ZrCl4 adsorption and dissociation on Ge/Si(100)-(2 x 1) surface as the initial stage of ZrO2 atomic layer deposition process are investigated with density functional theory (DFT). The Si-Si, Si-Ge and Ge-Ge one-dimer cluster mode ...

Investigation of notched composite wood-concrete connections

Julius Natterer

An initial stage of research on the feasibility of a composite concrete-wood commercial floors system is described. The floors are comprised of concrete placed atop a solid layer of dimension lumber. A notched shear key/anchor detail is used for interlayer ...

Antidepressant medication and the assimilation of problematic experiences in psychotherapy

Michael Christoph Gastpar

The authors assessed whether the psychotherapeutic process is enhanced by the addition of antidepressant medication. Mildly to moderately depressed patients received client-centered therapy with or without medication. Patients were assessed for symptoms of ...

A direct parallel sparse matrix solver

Kurt Appert, Trach-Minh Tran

The direct sparse matrix solver is based on a domain decomposition technique to achieve data and work parallelization. Geometries that have long and thin structures are specially efficiently tractable with this solver, provided that they can be decomposed ...

Initial-Stage Hot-Pressing Of Monosized Ti And 90-Percent Ti-10-Percent Tic Powders

Andreas Mortensen

The kinetics of the initial stage of uniaxial vacuum-hot-pressing of commercially pure spherical titanium powders are investigated for temperatures between 730 and 870-degrees-C and applied pressures from 25 to 50 MPa. Densification kinetics are found to a ...

Diffuse reflectance FTIR-spectroscopy for kinetic and mechanistic studies of CO2 hydrogenation in a continuous recycle reactor

Albert Renken

The advantage of coupling a diffuse-reflectance infrared cell with a continuous-feed recycle reactor for in situ kinetic and mechanistic studies is illustrated in the study of CO2 methanation over Ru/TiO2. From transient and steady-state experiments, metal ...
