SERS not to be taken for granted in the presence of oxygen

May 15, 2009
Author(s)
Melek Erol, Yun Han, Scott K. Stanley, Christopher Stafford, Henry Du, Svetlana Sukhishvili
In this communication, we report that oxidation of the Ag nanoparticle (Ag NP) surface under ambient conditions has a dramatic effect on the adsorption and SERS detection limit of nitroaromatic molecules in aqueous solutions. We show for the first time

Salt solubility and deposition in high temperature and pressure aqueous solutions

January 1, 2004
Author(s)
M S. Hodes, K A. Smith, Wilbur S. Hurst, Walter J. Bowers Jr., P Griffith, K Sako
Solubility and deposition experiments were performed with aqueous sodium sulfate and potassium sulfate solutions at elevated temperatures and pressures typical of the Supercritical Water Oxidation (SCWO) process. For all experiments the test cell was the

Reliability Issues of SiC MOSFETs: A Technology for High Temperature Environments

September 20, 2010
Author(s)
Liangchun (. Yu, Greg Dunne, Kevin Matocha, Kin P. Cheung, John S. Suehle, Kuang Sheng
… structure, however, it is widely believed that silicon oxide on SiC is physically limited, especially at high … experimental measurements of long-term reliability of oxide at high temperatures are necessary. In this work, … discussed and shown to be a possible indication that the oxide quality has not reached the intrinsic regime and …

Storage Conditions for High-Accuracy Composition Standards of AlGaAs

May 1, 2005
Author(s)
Kristine A. Bertness, Alexana Roshko, S. E. Asher, Craig L. Perkins
AlGaAs epitaxial films were stored under different environmental conditions and the resulting surface oxidation and contamination variations measured using several analytical techniques. Auger depth profiles confirmed that oxidation and carbon
