Morphological and Electrical Characterization of MWCNT Papers and Pellets

December 27, 2015
Author(s)
Elisabeth Mansfield, Ari D. Feldman, Ann C. Chiaramonti Debay, John H. Lehman, Alexandra E. Curtin
Six types of multiwall carbon nanotube soot were obtained and prepared into buckypapers by pellet pressing and by filtration into a paper. These samples were evaluated with respect to thickness, compressibility and electrical conductivity. DC conductivity

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

Atomically thin layers of B-N-C-O with tuneable composition

July 31, 2015
Author(s)
Ann C. Chiaramonti Debay, Birol Ozturk, Andres de Luna Bugallo, Eugene Panaitescu, Fangze Liu, Anthony Vargas, Xueping Jiang, Ozgur Yavuzcetin, Majed Alnaji, Yongui Zhao, Nicholas King, Madan Dubey, Saroj Nayak, Srinivas Sridhar, Swastik Kar
Atomically thin ternary compounds/alloys of boron, nitrogen and carbon have generated significant excitement as they provided the first instance of a tuneable 2D material that affords rich physics as well applications potentials. Interestingly, the crucial

Suppression of Spin Pumping between Ni80Fe20 and Cu by a Graphene Interlayer

June 7, 2015
Author(s)
William J. Gannett, Mark W. Keller, Hans Nembach, Thomas J. Silva, Ann Chiaramonti Debay
Abstract We compare ferromagnetic resonance measurements of Py (Ni80Fe20) films sputtered onto Cu(111) with and without a graphene (Gr) interlayer grown by chemical vapor deposition before Py deposition. We find the expected damping enhancement from spin

Stability and phase transfer of catalytically active platinum nanoparticle suspensions

May 9, 2015
Author(s)
Indira Sriram, Alexandra Curtin, Ann C. Chiaramonti Debay, Lauren F. Greenlee, Kavita M. Jeerage
In this work, we present a robust synthesis protocol for platinum nanoparticles that yields a monomodal dispersion of particles that are approximately 100 nm in diameter. We determine that these particles are actually agglomerates of much smaller particles

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

Applicability of post-ionization theory to laser-assisted field evaporation of magnetite

December 18, 2014
Author(s)
Ann C. Chiaramonti Debay, D. K. Schreiber, Lyle M. Gordon, Karen Kruska
Analysis of the mean Fe ion charge state from laser-assisted field evaporation of magnetite (Fe3O4) reveals unexpected trends as a function of laser pulse energy that break from conventional post-ionization theory for metals. For Fe ions evaporated from

Multiscale Correlative Measurements of Nanoparticles in Cells

August 26, 2014
Author(s)
Aric W. Sanders, Kavita M. Jeerage, Cindi Schwartz, Alexandra E. Curtin, Ann C. Chiaramonti Debay
Nanoparticles are emerging as invaluable tools in disease diagnosis, disease treatment and imaging contrast enhancement agents. The interactions of nanoparticles with host organisms are complex and affect biological systems over length scales that vary
