1. Chemical imaging beyond the diffraction limit using photothermal induced resonance microscopy
Topic: Chemical Analysis
Published: 4/2/2013
Authors: Andrea Centrone, Basudev Lahiri, Glenn E Holland
Abstract: Photo Thermal Induced Resonance (PTIR), recently attracted great interest for enabling chemical identification and imaging with nanoscale resolution. In this paper, the PTIR working principles are reviewed along the main results from a recent publica ...

3. Discriminating the states of matter in metallic nanoparticle transformations: What are we missing?
Topic: Chemical Analysis
Published: 2/20/2013
Authors: John M. Pettibone, Julien Claude Maurice Gigault, Vincent A Hackley
Abstract: A limiting factor in assessing the risk of current and emerging nanomaterials in biological and environmental systems is the ability to accurately detect and characterize their size, shape and composition in broad distributions and complex media. Asy ...

4. Chemical Imaging Beyond the Diffraction Limit: Experimental Validation of the PTIR Technique
Topic: Chemical Analysis
Published: 2/11/2013
Authors: Basudev Lahiri, Glenn E Holland, Andrea Centrone
Abstract: Photo Thermal Induced Resonance (PTIR), recently attracted great interest for enabling chemical identification and imaging with nanoscale resolution. In this work, electron beam nano-patterned polymer samples were fabricated directly on 3-dimentional ...

5. Evaluation of C60 Secondary Ion Mass Spectrometry for the Chemical Analysis and Imaging of Fingerprints
Topic: Chemical Analysis
Published: 1/22/2013
Authors: Edward Ryan Sisco, Leonard Demovanville, John G Gillen
Abstract: The feasibility of using C60 Cluster Primary Ion Bombardment Secondary Ion Mass Spectrometry (C60 SIMS) for the analysis of the chemical composition of fingerprints is evaluated. It was found that C60 SIMS could be used to detect and image the spat ...

6. Weathering Patterns of Ignitable Liquids with the Advanced Distillation Curve Method
Series: Journal of Research (NIST JRES)
Report Number: 118.003
Topic: Chemical Analysis
Published: 1/17/2013
Authors: Samuel Allen, Thomas J Bruno
Abstract: One can take advantage of the striking similarity of ignitable liquid vaporization (or weathering) patterns and the separation observed during distillation to predict the composition of residual compounds in fire debris. This is done with the ad ...

8. Nanoscale Specific Heat Capacity Measurements Using Optoelectronic Bilayer Microcantilevers
Topic: Chemical Analysis
Published: 12/12/2012
Authors: Brian Gregory Burke, William A Osborn, Richard Swift Gates, David A LaVan
Abstract: We describe a new technique for optically and electrically detecting and heating bilayer microcantilevers (Pt−SiNx) to high temperatures at fast heating rates for nanoscale specific heat capacity measurements. The bilayer microcantilever acts s ...

9. East versus West: Organic Contaminant Differences in Brown Pelican (Pelecanus occidentalis) Eggs from South Carolina, USA and the Gulf of California, Mexico
Topic: Chemical Analysis
Published: 11/1/2012
Authors: Stacy S Vander-Pol, Daniel W. Anderson, Patrick G. R. Jodice, Joyce E. Stuckey
Abstract: Brown pelicans (Pelecanus occidentalis) were listed as endangered in the United States in 1970, largely due to reproductive failure and mortality caused by organochlorine contaminants, such as DDT. The southeast population, P.o. carolinensis, was del ...
