Theoretical investigations and technology developments during last years have created new conceptual approach to design and build a new class of plasma wave electronics detectors of terahertz (THz) wave range. Terahertz radiation corresponds to thefrequency bands of molecular and lattice vibrations in gases, fluids, and solids. THz detectors with higher sensitivity is urgently need for important a ...

Chemical warfare agents with their low vapor pressure can stay on a surface for long periods of time and pose a serious threat to anyone coming into contact with the surface. A standoff sensor that can visualize and identify such a threat is of greatinterest to the US military.Pacific Advanced Technology (PAT) has a technology with the capability of standoff detection and the potential for identif ...

Microbial degradation is an effective method of decontaminating pools of free-phase pollutants, such as chlorinated solvents and explosives, in groundwater. The formation of microbial consortia capable of residing on free-phase contaminants has been shownrecently by the proposer. The population obtained in a continuous selection process exhibited increased surface hydrophobicity, considered to b ...

The large area of the human skin and its exposed position on the body surface make it an important portal of entry for toxic agents. Pesticides are able to penetrate the skin and reach the systemic blood and other tissue. Pericor Science has developed atechnology by means of which a pesticide-degrading enzyme can be coupled to the cornified layer of the human epidermis by covalent bonds introduced ...

Recent measurements of the electromagnetic transmission through bacillus subtillus, an anthrax facsimile, have revealed absorption resonances in the THz region. A system-level analysis previously carried out by the proposer has shown that at least oneof the resonances (centered at 14.05 cm-1, or 421 GHz) is located at a frequency of low enough atmospheric absorption to be detectable by an activ ...

The Phase-I effort has produced three key results as the foundation for the Phase-II proposal. First, vector network analyzer measurements of a Bacillus subtillis (an Anthrax surrogate) sample has yielded promising absorption signatures around 425 and 445GHz. These are believed to be the most accurate measurements ever made of an Anthrax-like biopaticle in the sub-1.0 THz region. Second, the ke ...

Two fundamental challenges face development of the magnetic-resonance force microscope (MRFM): sensitivity and image deconvolution. Because of the non-local nature of the MRFM response to a single spin, image processing of as-captured MRFM data will be socritical a component of the instrument that its performance will have a profound impact on the entire system design. In this Phase I STTR project ...

The video surveillance industry is experiencing dramatic change with the move from analog to digital video. Command centers need to have coordinated viewing of multiple camera feeds at one time, and the ability to switch automatically between feeds and display relevant patterns. Conventional security control rooms include a bank of monitors connected through a switch to an array of security camera ...
