1. Morphological and Electrical Characterization of MWCNT Papers and Pellets
Published: 12/27/2015
Authors: Elisabeth Mansfield, Ari D Feldman, Ann Chiaramonti Chiaramonti Debay, John H Lehman, Alexandra E Curtin
Abstract: 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 con ...

2. Gold Nanoparticle Quantitation by Whole Cell Tomography
Published: 11/13/2015
Authors: Aric Warner Sanders, Kavita M Jeerage, Cindi Schwartz, Alexandra E Curtin, Ann Chiaramonti Chiaramonti Debay
Abstract: 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 character ...

3. Localization and Number of Au Nanoparticles in Optically Indexed Cells by FIB Tomography
Published: 8/2/2015
Authors: Aric Warner Sanders, Kavita M Jeerage, Ann Chiaramonti Chiaramonti Debay, Alexandra E Curtin
Abstract: 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 stabi ...

4. Atomically thin layers of B-N-C-O with tuneable composition
Published: 7/31/2015
Authors: Ann Chiaramonti 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
Abstract: 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 ...

5. Timescale of Silver Nanoparticle Transformation in Neural Cell Cultures Impacts Measured Cell Response
Published: 7/7/2015
Authors: Stephanie L. Hume, Ann Chiaramonti Chiaramonti Debay, Katherine P. Rice, Rani K. Schwindt, Robert I. MacCuspie, Kavita M Jeerage
Abstract: Serum protein concentration and ionic strength are important factors in nanoparticle transformation within cell culture environments. However, silver nanoparticles are not routinely tracked at their working concentration in the specific medium used f ...

6. Suppression of Spin Pumping between Ni80Fe20 and Cu by a Graphene Interlayer
Published: 6/7/2015
Authors: William J. Gannett, Mark W Keller, Hans Toya Nembach, Thomas J Silva, Ann Chiaramonti Chiaramonti Debay
Abstract: 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 f ...

7. Transition from order to configurational disorder for surface reconstructions on SrTiO 3(111)
Published: 6/2/2015
Authors: Ann Chiaramonti Chiaramonti Debay, Laurence D Marks , Shams Rahman, Martin Castell
Abstract: There is growing interest in oxide surfaces due to their role in areas ranging from the growth of oxides for low power electronics to heterogeneous catalysis. However, there are still many uncertainties about their atomic structure although substan ...

8. Stability and phase transfer of catalytically active platinum nanoparticle suspensions
Published: 5/9/2015
Authors: Indira Sriram, Alexandra E Curtin, Ann Chiaramonti Chiaramonti Debay, Lauren F. Greenlee, Kavita M Jeerage
Abstract: 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 p ...

9. Citrate-stabilized gold nanoparticles do not impact neural progenitor cell development
Published: 1/5/2015
Authors: Kavita M Jeerage, Tammy L. Oreskovic, Alexandra E Curtin, Aric Warner Sanders, Rani K. Schwindt, Ann Chiaramonti Chiaramonti Debay
Abstract: 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 ...

10. Applicability of post-ionization theory to laser-assisted field evaporation of magnetite
Published: 12/18/2014
Authors: Ann Chiaramonti Chiaramonti Debay, D. K. Schreiber, Lyle M Gordon, Karen Kruska
Abstract: 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 ...
