Laser Heating of Solid Hydrogen for Production of Vibrationally Excited Molecules for Use in Negative Hydrogen Ion Sources
… light was used to heat hydrogen pellets on a metallic substrate. The purpose of heating the hydrogen is to create a vibrationally excited population of hydrogen for use in negative hydrogen ion sources. The desired heating temperature is 3000-6000 K.

Enhancement and extinction effects in surface-enhanced stimulated Raman spectroscopy
… fields from spontaneous Raman scattering near a metallic substrate. By utilizing stimulated Raman scattering over spontaneous Raman scattering, the effect of the enhancement of the local fields will be increased due to nonlinear excitations. An electromagnetic derivation for the enhancement of …

A Correlated 1-D Monatomic Condensed Matter System: Experiment and Theory
… vacuum conditions on a vicinal copper (111) substrate using a recipe developed specifically for this work. This work experimentally demonstrates that this 1-D system undergoes a charge density wave instability, which is a first for such a 1-D phenomenon on a metallic substrate. It is …

Characterization of thermally diffused bordie layers on AISI 1018 steel : residual stresses (by synchrotron radiation) and microhardness
… boride layers are formed at the surface of the metallic substrate. The boride coatings formed by the diffusion process have high hardness and strong ware and corrosion resistance. In order for coatings of this nature to be industrially successful, their service life should be long and …

Microstructural Development and Superconducting Parameters of the YBa2Cu3O7-delta Coated Conductor
… a high Tc superconducting layer onto a flexible metallic substrate, using intermediate buffer layers to prevent chemical interaction. In order for the superconductor to be capable of carrying a high current density, its grains must have good crystallographic alignment in order to avoid the …

Growth and characterization of epitaxial graphene films by Molecular Beam Epitaxy
… Chemical Vapor Deposition (CVD) of graphene on metallic substrates and thermal decomposition of SiC are two such efforts in the direction of producing wafer-scale graphene films but none of these techniques are full-proof. While CVD graphene needs to be transferred from a metallic substrate to an …
