In this Phase II program, improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies, which Amethyst has successfully demonstrated in the Phase I program: unipolar barrier (e.g., nBn) detector structures, and defect passivation via hydrogenation. This two-pronged approach addresses the main performance limitation of extend ...

Millions of heat pumps are used to heat and cool homes and buildings year round. Continuous operation means that components wear out at a greater rate. As a result, maintenance of residential heat pumps is a major cost driver. Current methods focus on reduced use through control settings. Typically, demand has wide swings throughout the day and people are unable to customize controls. Inevitably, ...

Single-walled carbon nanotubes (SWCNTs) have unique material properties making them very attractive for use in a variety of electronic applications. However, as-grown SWCNTs contain a mixture of tubes with heterogeneous optical and electronic properties. The chiral species must be separated in order to maximize the desired properties. To date, no large scale separation process has been accomplishe ...

A longwire antenna module is proposed, incorporating a length reduction technique that yields 25-75% length reduction with minimal impact on gain. A resonant monopole antenna operating at 535kHz is approximately 440ft long; length reduction techniques will reduce this to between 69ft and 134ft depending upon the desired gain. A shorter/lighter longwire antenna will allow the aircraft to be more ...

An antenna system is proposed for the purpose of FM, TV-VHF, and TV-UHF PSYPOS broadcast applications. The antenna system incorporates a radiating structure that is small, light weight, and conformal. A circularly polarized beam is broadcast from an aircraft towards nadir, illuminating the region below the craft with a horizontally-polarized signal, yielding polarizations pointing in both the No ...

Regenerative medicine is an emerging, interdisciplinary field that will result in new engineered medical products. The introduction of a high-resolution, non-destructive imaging technique that is capable of penetrating deeply into the highly-scattering scaffold medium has the means to accelerate the development and commercial utilization of these novel materials. Multi-photon microscopy (MPM) is b ...
