Qualitative Multidimensional Calibration Comparison

January 15, 2018
Author(s)
Aric W. Sanders, Ronald A. Ginley, Christian J. Long, Jasper A. Drisko, Nathan D. Orloff, Richard A. Chamberlin
We present a technique for the visual comparison of any two vector network analyzer calibrations. This method visualizes the comparative action of the calibrations for multiple complex scattering parameters relative to the calibrated measurement plane

Polarity-Controlled GaN/AlN Nucleation Layers for Selective-Area Growth of GaN Nanowire Arrays on Si(111) Substrates by Molecular Beam Epitaxy

December 18, 2015
Author(s)
Matthew D. Brubaker, Shannon M. Duff, Todd E. Harvey, Paul T. Blanchard, Alexana Roshko, Aric W. Sanders, Norman A. Sanford, Kristine A. Bertness
We have demonstrated dramatic improvement in the quality of selective-area GaN nanowire growth by controlling the polarity of the underlying nucleation layers. In particular, we find that N- polarity is beneficial for the growth of large ordered nanowire

Gold Nanoparticle Quantitation by Whole Cell Tomography

November 13, 2015
Author(s)
Aric W. Sanders, Kavita M. Jeerage, Cindi Schwartz, Alexandra Curtin, Ann C. Chiaramonti Debay
Many proposed biomedical applications for engineered gold nanoparticles require their incorporation by mammalian cells in specific numbers and locations. Here, the number of gold nanoparticles inside of individual mammalian stem cells was characterized

Localization and Number of Au Nanoparticles in Optically Indexed Cells by FIB Tomography

August 2, 2015
Author(s)
Aric W. Sanders, Kavita M. Jeerage, Ann C. Chiaramonti Debay, Alexandra Curtin
Gold nanoparticles (GNPs) are gaining importance as therapeutic chemical delivery vehicles, medical diagnostic tools, phototherapeutic and contrast enhancement agents. GNPs are uniquely suited for these biological uses because of their chemical stability

Citrate-stabilized gold nanoparticles do not impact neural progenitor cell development

January 5, 2015
Author(s)
Kavita M. Jeerage, Tammy L. Oreskovic, Alexandra Curtin, Aric W. Sanders, Rani K. Schwindt, Ann C. Chiaramonti Debay
Gold nanoparticles are promising candidates for medical diagnostics and therapeutics, due to their chemical stability, optical properties, and ease of functionalization. Citrate-stabilized gold nanoparticle reference materials also have potential as

Biomass Particle Models with Realistic Morphology and Resolved Microstructure for Simulations of Intraparticle Transport Phenomena

December 9, 2014
Author(s)
Peter Ciesielski, Michael F. Crowley, M R. Nimlos, Aric Sanders, Gavin Wiggins, Bryon Donohoe
Biomass exhibits a complex microstructure of directional pores that can vary substantially between species of origin. However, models of biomass particles employed in simulations of conversion processes typically employ over-simplified geometry such as

Junction Yield Analysis for 10 V Programmable Josephson Voltage Standard Devices

December 5, 2014
Author(s)
Anna E. Fox, Paul D. Dresselhaus, Alain Rufenacht, Aric W. Sanders, Samuel P. Benz
Analysis of the Josephson junction yield in the National Institute of Standards and Technology 10 V Programmable Josephson Voltage Standard (PJVS) has been performed by fabricating and measuring over 25 million Nb/NbxSi1-x/Nb junctions. Using the 265,116
