Antenna coupled niobium bolometers for 10 (mu)m radiation detection

June 1, 2005
Author(s)
Robert Hadfield, Aaron J. Miller, Sae Woo Nam, Erich N. Grossman, Robert E. Schwall,
We report on the fabrication and testing of antenna-coupled niobium bolometers for 10-micron wavelength radiation detection. We use 20 nm thick Nb films on oxidized Si substrates. The bolometer design consists of a 1 micron x 1 micron Nb microbridge

Accelerator Aging Effects During Copper Electrodeposition

April 1, 2003
Author(s)
Thomas P. Moffat, B C. Baker, Daniel Wheeler, Daniel Josell
Slow sweep rate voltammetric analysis of the Cu/Cu(II) deposition reaction is shown to be an effective tool for examining aging effects associated with thiol and disulfide additives that are widely employed as brighteners. Sulfonate-terminated short chain

Size-Monodisperse Metal Nanoparticles Via Hydrogen-Free Spray Pyrolysis

April 3, 2002
Author(s)
Jung Hyeun Kim, Thomas A. Germer, George Mulholland, S H. Ehrman
Pure copper nanoparticles were produced using a co-solvent approach avoiding use of hydrogen or other reducing gas. Compared with the particles formed without the co-solvent, the addition of alcohol has a significant effect in preventing oxidation, which

Thermal Plasma Synthesis of Fe-Co Alloy Nanoparticles

June 1, 1998
Author(s)
J H. Scott, Z Turgut, K Chowdary, M E. McHenry, S. A. Majetich
FeCo nanoparticles are synthesized in a radio frequency (RF) plasma torch from metal powder precursors and simple gases. The first precursor consists of pre-alloyed FeCo powder; the second precursor is a mixture of elemental Fe and Co powders. A protective
