Nanodroplet Real-Time PCR System with Laser Assisted Heating
We report the successful application of low-power (~30 mW) laser radiation as an optical heating source for high-speed real-time polymerase chain reaction (PCR) amplification of DNA in nanoliter droplets dispersed…

Petri Dish PCR: Laser-Heated Reactions in Nanoliter Droplet Arrays
We report high-speed real-time PCR performed on an unmodified disposable polystyrene Petri dish. The reaction cycle relies solely on an infrared laser for heating; no conventional heater is required.

Calorimetry of Pulse Elecro-Melting of PdDx Wires
The ultimate extrapolation of this technology is the electrical heating of thin PdDx wires resulting in destructive high-speed melting - “exploding wires”. Exploding wire technology has been used for over…

Characterization of Hydrogen-Assisted Fracture Mechanism By Fracture Surface Topography Analysis (FRASTA)
The fracture surface topography analysis (FRASTA) technique was applied to the crack arrest threshold region in a wedge-opening-load (WOL) ASME SA 372 Grade J sample tested in hydrogen gas at…

Classification and Selective Collection of Individual Aerosol Particles Using Laser-Induced Fluorescence
We describe the development and performance evaluation of a system for optical interrogation, subsequent selection, and collection of individual aerosol particles entrained in an inlet air stream.

Producing Propylene 
 Glycol from Biomass
Process and catalytic considerations for producing propylene glycol from glycerin-derived biomass sources are compared to current conventional sources, while economic factors and potential markets are discussed

Form GaAs/IngaAs Lasers on Virtual Ge
This article reports on 980-nm GaAs/In- GaAs lasers grown on virtual Ge substrates, for which the Ge thin film was grown on Si (001) substrates via the ART method followed…

Testing Aerosol Properties in MODIS Collection 4 and 5 Using Airborne Sunphotometer Observations in INTEX-B/MILAGRO
We compare AATS retrievals of spectral aerosol optical depth (AOD) and related aerosol properties with corresponding spatially coincident and temporally near-coincident measurements acquired by the MODIS-Aqua and MODIS-Terra satellite sensors.

Frequency Domain Measurements on Turbid Media with Strong Absorption Using the Pn Approximation
We have applied the frequency-domain technique to measurement of the optical properties of turbid media with strong absorption in the infinite medium limit.

From Cold Fusion to Condensed Matter Nuclear Science: 20 Years of Research
Nuclear fusion, as conventionally understood, is a process whereby the nuclei of light elements fuse together to form heavier ones.

Laser Heated Nanodroplet PCR on a Petri Dish
We report the development of a real-time PCR system driven solely by laser heating with nanoliter droplets on a polystyrene Petri dish.
