Chemical agents in aerosol form have been identified as a major threat, and there is now interest in applying the long wave infrared frequency agile laser sensor to detection of this important agent form. If successful, it would be possible to perform detection of chemical agent vapors and aerosols and biological aerosol agents with a single dual-use sensor. To accomplish this, it is critical to ...

This proposal addresses the need to increase the probability of detection (PD) and reduce the probability of false alarm (PFa) for non-contact, real-time sensors for trace levels of biological and chemical targets using simultaneous detection of Raman and fluorescence emissions. Raman spectroscopy is a spectroscopic method that provides information about molecular bonds in target materials. F ...

Lithium-air battery consists of a lithium anode electrochemically coupled to atmospheric oxygen through an air cathode. The major advantages of lithium air batteries are that air cathode active material, oxygen, is not stored internal to cell system and lithium anode being extremely lightweight metal with a highest theoretical specific energy density. This energy density is well comparable with t ...

A method is proposed for the simultaneous imaging of temperature and velocity fields inside combustion chambers to enable experimental data on turbulent heat fluxes needed for model validation and development. Applications include turbine engines, afterburners, internal combustion engines, and boilers. Temperature imaging is proposed with laser-induced luminescence imaging of phosphor particles su ...

The Phase I effort was successful in experimentally showing feasibility of a combined isotope transmitter that can be developed and demonstrated under the Phase II program. The initial experimental results give the window of gas mixtures for a stable discharge. Laser extraction tests were accomplished with C12/C13 mixtures to give guidance for further work to increase laser gain. For application ...

Results of the Phase I work showed that an advanced, compact Point Sensor can be built with good sensitivity for detection of both biological agents and chemical aerosol and vapor agents. This will be the first point sensor capable of this dual role. The

Defects of mitochondrial performance limit physical and cognitive endurance, and resistance to age-related deterioration and trauma. However large scale screens to identify drug-like compounds that improve mitochondrial function have not taken place, bec

As the U.S. Government increases participation in post-conflict Stabilization and Reconstruction Operations (SARO) around the globe, the ability to understand the relationships between task completion and mission completion is critical. The US Government employs a metrics tool developed though the Monitoring Progress in Conflict Environments project. The objective of this Phase II STTR is to provi ...

Currently large capacity cryostats, capable of hosting experiments for many qubits, require expensive and hard to obtain liquid cryogens. A few small cryo-free systems exist but they are non-ideal for this use. An opportunity exists for a large scale, c

An eye-safe optically pumped laser based on a gas-filled hollow optical fiber will be demonstrated to lase at both near infrared (IR) and mid IR wavelengths. These lasers will be the first in a new class of IR lasers, based on the combination of hollow-f
