1. 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 ...

2. 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 ...

3. Co-existing Tetrahedral and Octahedral Coordination on Strontium Titanate (111) Surface
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 ...

4. Suppression of Spin Pumping between Ni80Fe20 and Cu by a Graphene Interlayer
Published: 6/2/2015
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 ...

5. 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 ...

6. 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 ...

7. 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 ...

8. A Simplified Approach to Determining Resolutions for Optical, Ion and Electron Microscope Images
Published: 8/26/2014
Authors: Alexandra E Curtin, Ann Chiaramonti Chiaramonti Debay, Aric Warner Sanders

9. Electron and Helium Ion Imaging of Arabidopsis Affected by Genetic Mutation and Surface Acid Treatment for Biofuel Applications
Published: 8/26/2014
Authors: Alexandra E Curtin, Ann Chiaramonti Chiaramonti Debay, Aric Warner Sanders

10. Multiscale Correlative Measurements of Nanoparticles in Cells
Published: 8/26/2014
Authors: Aric Warner Sanders, Kavita M Jeerage, Cindi Schwartz, Alexandra E Curtin, Ann Chiaramonti Chiaramonti Debay
Abstract: 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 va ...
