Hydrogen in nano-diamond films: experimental and computational studies

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Thermionic Emission from Diamond Films in Molecular Hydrogen Environments

Diamond-based low-work function thermionic electron emitters are in high demand for applications ranging from electron guns and space thrusters to electrical energy converters. A key requirement of such diamond-based electron sources is hydrogen termination of the surfaces which can significantly reduce the emission barrier. However, at high temperatures (≤600°C), terminated hydrogen begins to ...

Nano-crystalline Diamond Films for X-ray Lithography Mask

Electronic Structure Studies on Reactive Nano - Films

The present research effort developed a real-space formulation for orbital-free density functional theory and Kohn-Sham density functional theory in order to conduct large-scale electronic structure calculations that take an important step towards addressing the prevailing domain-size and geometry limitations of existing electronic-structure codes. In particular, by combining the real-space for...

Laser Raman Studies of Polycrystalline and Amorphic Diamond Films

This report describes the results of a number of different, but related, laser Raman studies on various CVD diamond samples. It attcmpts to show the versatility of Raman spectroscopy as a diagnostic tool for the quality of diamond films, by demonstrating its use in a few novel applications. The studies of the laser Raman spectra of amorphic diamond and CVD diamond films are performed using lase...
