Energy Dispersive Spectrometry

October 16, 2008
Author(s)
Dale E. Newbury
Energy dispersive x-ray spectrometry (EDS) is a spectral measurement tool used with a wide variety of excitation sources: electrons, ions and x-ray. Photon measurement is based on photoelectric absorption and conversion into charge. The process is serial

Phase Equilibria of the SrO-Yb 2 O 3 -CuO x System in Air

September 1, 2001
Author(s)
J Dillingham, Winnie Wong-Ng, Igor Levin
The phase diagram of the SrO-Yb 2O 3-CuO x system was investigated in air. The solid solution (Sr 14-xYb x)Cu 24O z (O 13Yb)Cu 24O z indicated that this phase is incommensurate, with the modulation wave vector q=(1/2-z)c*, znearly equal to}0.066. The Sr

Electron Collision Cross Sections Derived from Critically Assessed Data

July 1, 1999
Author(s)
Loucas G. Christophorou, James K. Olthoff
Electron-molecule collisions are among the most fundamental processes in gas discharges. They are also the precursors of the ions and the radicals which drive the etch, cleaning, or deposition processes in plasma reactors. Hence, there is a need for a

Polyelectrolyte Adsorption on Hydroxyapatite

November 1, 2001
Author(s)
Vincent A. Hackley
Hydroxyapatite (HAP) belongs to a family of structurally and chemically related, sparingly soluble calcium phosphate (CP) salts [1], and is the structural prototype for the principal mineral component of bone and teeth [2]. Well-defined synthetic HAP has
