1. Evaluation of C60 Secondary Ion Mass Spectrometry for the Chemical Analysis and Imaging of Fingerprints
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 ...

2. Evaluation of a drop-on-demand micro-dispensing system for development of artificial fingerprints
Published: 12/7/2012
Authors: Jessica L Staymates, Matthew E Staymates, John G Gillen
Abstract: Precision micro-dispensing is a growing technique that has many applications in the scientific and additive manufacturing communities. Piezoelectric inkjet printing is capable of accurately dispensing exceedingly small volumes of low-viscosity soluti ...

3. High-speed thermo-microscope for imaging thermal desorption phenomena
Published: 7/25/2012
Authors: Matthew E Staymates, John G Gillen
Abstract: In this work, we describe a new imaging system, called a thermo-microscope, that can be used to visualize atmospheric pressure thermal desorption phenomena at high heating rates and frame rates. The system consists of a zoom lens coupled to a high-sp ...

5. Fabrication of Adhesive Collection swabs for Improved Swipe-Based Particle Collection Efficiency
Published: 9/2/2011
Authors: Jessica L Staymates, Jessica M Grandner, John G Gillen
Abstract: A technique was developed to improve the particle collection efficiency of commercially-available collection swabs. Improving the particle collection efficiency can provide a better chance of detection when screening for trace explosives particles. A ...
