Surface Analytical Kinetic Studies of Noise-Generating Electron Transfer Processes: In Vivo Sensing Properties of Nanoengineered Organic Cardiac Pacing Electrodes in Living Heart

October 12, 2021
Author(s)
H A. Chou, P DaeGynn, David J. Vanderah, M Ovadia
Novel organic cardiac electrode candidates enhanced by self-assembled monolayers (SAMs) are examined by varying rate cyclic voltammogram and impedance spectroscopy with hexacoordinated [Fe(CN)6]-3 as the probe for their susceptibility to Faradaic current

Surface Energy Anisotropy of SrTiO 3 at 1400 C in Air

October 12, 2021
Author(s)
T Sano, D M. Saylor, G S. Rohrer
Geometric and crystallographic measurements of grain boundary thermal grooves and surface faceting behavior as a function of orientation have been used to determine the surface energy anisotropy of SrTiO 3 at 1400 C in air. Under these conditions, thermal

Surface Morphology Dependent Magnetic Thin Film Growth: Fe on GaN(0001)

October 12, 2021
Author(s)
P Ryan, R A. Rosenberg, D J. Keavney, J W. Freeland, Joseph Woicik
Iron deposition on ordered and disordered GaN (0001) surfaces result in dramatically different magnetic over-layer characteristics. On the ordered surface, nitrogen rapidly desorbs upon Fe deposition and a magnetically disordered film is produced

Surface Treatment of Mercury Free Alloys

October 12, 2021
Author(s)
S B. Geiger, D Gurbatov, M P. Dariel, F Eichmiller, R Liberman, M Ratzker
Finishing and polishing methods were examined for two metallic direct restorative materials being proposed as possible alternatives to amalgam, namely a gallium alloy and a consolidated silver alloy. The polished surfaces were compared to a conventional

Synchrotron Based Surface Science to Probe Polymeric Interfacial Regions

October 12, 2021
Author(s)
Joseph~undefined~undefined~undefined~undefined~undefined Lenhart, Daniel A. Fischer
Synchrotron based X-ray absorption spectroscopy was utilized to probe the chemistry and structure of polymers in interfacial regions, including the interfacial regions, including the interfacial composition of filled epoxy composites, and the surface

Synthesis and Characterization of Siloxy-Containing Imidazolium Ionic Liquids

October 12, 2021
Author(s)
Paul A. Wheeler, Jeffrey W. Gilman, L J. Mathias
A novel family of siloxy-containing imidazolium ionic liquids was synthesized and their thermal and decomposition properties studied. Three of the four compounds exhibited an unexpectedly low decomposition temperature of ca. 200 C that appears to be due to

Synthesis of Imidazolium Salts and Their Application in Epoxy Montmorillonite Nanocomposites

October 12, 2021
Author(s)
Joseph Langat, S Bellayer, P Hudrlik, A Hudrlik, P H. Maupin, Jeffrey W. Gilman, D T. Raghavan
Considerable research has been conducted in improving the performance characteristics of nanocomposites, however, relatively few attempts have been made to address the thermal stability of nanocomposite. An attempt is being made to improve the thermal

Synthesis, structure, electronic and thermal properties of sphalerite CuZn2InS4

October 12, 2021
Author(s)
Oluwagbemiga P. Ojo, Wilarachchige D. C. B. Gunatilleke, Hagen Poddig, Hsin Wang, Joshua B. Martin, Dylan J. Kirsch, George S. Nolas
Quaternary chalcogenides continue to be of interest due to the variety of physical properties they possess, as well as their potential for different applications of interest. Investigations on materials with the sphalerite crystal structure have only

Systematic Study of Cancellation of Errors in the Benzene Dimer Interaction Energy

October 12, 2021
Author(s)
Ines Gonzalez, Stephen L. Garrison, M Marquez, Carlos A. Gonzalez, E C. Lim
We present a broadly applicable method or diagnostic for the appropriateness of the counterpoise correction and illustrate its value via calculations on the benzene dimer. The results also explain the fortuitous cancellation of errors that led to good

Tailoring the High-K Gate Dielectric/Sillicon Interface for CMOS Applications

October 12, 2021
Author(s)
Y S. Lin, R Puthenkovilakam, J P. Chang, C P. Bouldin, Igor Levin, Nhan Van Nguyen, Y Sun, P Pianetta, T Conard, W Vandervorst, V Venturo, S Selbrede
The interfacial properties, thermal stabilities, and the electrical characteristics of ZrO 2/ Si and ZrO 2/SiO 2/Si were investigated and the interfacial layer of as-deposited ZrO 2 on silicon is likely to be ZrSi xO y. The ZrO 2/ZrSi xO y/Si is
