Fullmoon has the first chip-level sensors capable of identifying and quantifying molecules in the air. At the core of our technology are printed voltammetric sensors, which are operated using cyclic voltammetry, an electrochemical technique that probes for the redox potential, a unique signature of molecules. We have demonstrated this sensing principle for the detection of carbon monoxide and meth ...

In this Small Business Innovative Research (SBIR) effort, Nikira Labs Inc. proposes to develop a compact Raman fiber optic probe with inline spectral filtering that improves fiber-coupled Raman measurements by filtering out Raman scattering from the excitation fiber and elastically scattered laser light from the collection fibers. The technology will enable compact fiber probes for Raman studies i ...

We propose to demonstrate near infrared (NIR) InGaAs sensor arrays with 55% lower noise than arrays presently available to improve the sensitivity of current spectroscopy systems. The low noise performance will be enabled by the use of low-noise source follower per detector ROICs, which are also used in astronomy with HgCdTe for low noise measurements. With design improvements to current available ...

A high sensitivity laser-induced incandescence system is proposed for the detailed characterization of environmental soot. The Phase 1 effort has clearly demonstrated the feasibility of (1) reducing the lower detection limit of soot volume fraction and increasing the overall measurement range by at least 2 orders of magnitude from what is currently achievable, and (2) providing PM particle size me ...

NIST is seeking a large area solar simulator to overcome the shortcomings of current solar simulators. To meet this need, Physical Optics Corp. (POC) proposed to develop a new Holographic Light-Emitting-Diode-Based Solar Simulator (HOLIOS) based on holographic gratings, holographic diffuser, high-power light emitting diodes with electronic drivers, collimating and projection optics, and photodetec ...

The objective of this proposal is to create a prototype imaging variable kinetic energy electron analyzer in the range 0.1 to 8 keV for use with an X-ray excitation source. The imaging analyzer is to have a target imaging spatial resolution of 100 nm. The X-ray excitation source will be a synchrotron light source. The instrument can be described as an X-ray photoelectron spectroscopy (XPS) microsc ...

THERE HAS RECENTLY BEEN HEIGHTENED CONCERN FOR THE POSSIBILITY THAT NUCLEAR POWER-PLANT ACCIDENTS DURING SHUTDOWNS COULD BE IMPORTANT CONTRIBUTORS TO THE OVERALL RISK PROFILE OF THESE PLANTS. THE 1986 SOVIET ACCIDENT AT CHERNOBYL WAS THE PRINCIPAL EVENT THAT LED TO THIS HEIGHTENED CONCERN, BUT A FEW RECENT EVENTS AT U.S. PLANTS HAVE ALSO CONTRIBUTED. TODAY, IT IS WIDELY UNDERSTOOD THAT THE RISK OF ...
