Raman microspectroscopy is a laboratory technique used to produce molecular fingerprints of materials and biological specimens. However, to date, fluorescence has interfered with effective application...
Discrimination of color copier/laser printer toners by Raman spectroscopy and subsequent chemometric analysis
Forensics Raman Color Toners Chemometrics
2015/5/21
Toner analysis has become an area of increased interest due to the wide availability of laser printers and photocopiers. Toner is most often encountered on paper in questioned document analysis. Becau...
Instrumental and Chemometric Analysis of Automotive Clear Coat Paints by Micro Laser Raman and UV Microspectrophotometry
Raman microspectrophotometry clear coat automotive paint chemometrics forensic
2015/5/21
Automotive paints have used an ultraviolet (UV) absorbing clear coat system for nearly thirty years. These clear coats have become of forensic interest when comparing paint transfers and paint samples...
Making the best of mixed-field orientation of polar molecules: A recipe for achieving adiabatic dynamics in an electrostatic field combined with laser pulses
mixed-field orientation of polar molecules recipe adiabatic dynamics electrostatic field laser pulses Chemical Physics
2012/4/24
We have experimentally and theoretically investigated the mixed-field orientation of rotational-state-selected OCS molecules and we achieve strong degrees of alignment and orientation. The applied mod...
Application of Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry to studies of chemical diffusion, sorption, and transport in natural rock
imbibition diffusion sorption transport rock
2017/4/11
We applied laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) techniques to make spatial
measurements of chemical tracer concentrations in three natural rock types (tuff, sandsto...
We investigated carrier-relaxation dynamics of femtosecond laser annealed (FLA) polycrystalline silicon (poly-Si). The correlation between morphology and electrical properties of poly-Si after femtose...
Rotational spectrum of asymmetric top molecules in combined static and laser fields
static and laser fields molecules
2011/8/31
We examine the impact of the combination of a static electric field and a non resonant linearly polarized laser field on an asymmetric top molecule. Within the rigid rotor approximation, we analyze th...
Visualization of Spatial Distribution of γ-Aminobutyric Acid in Eggplant (Solanum melongena) by Matrix-assisted Laser Desorption/Ionization Imaging Mass Spectrometry
Visualization Spatial Distribution γ-Aminobutyric Acid
2010/9/14
We applied imaging mass spectrometry (IMS) to determine the spatial distribution of γ-aminobutyric acid (GABA). We found that GABA had a specific localization in seeds. We also visualized various biom...
