High performance infrared photodetectors and light sources that span infrared wavelengths from 2 to 14 microns and beyond are critical to DoD. At the longer wavelengths these devices demand stringent cooling requirements, which add size, weight, power consumption and cost. In this program we are developing tunnel diodes based on epsilon near zero (ENZ) metal-insulator-metal (MIM) rectenna structur ...

A critical SWAP-C requirement for future IR systems is the ability to operate at room temperature (RT). While some IR devices such as microbolometers operate at RT, their speed and detectivity is compromised. Therefore, the functionality of IR platforms can still be improved. Tunnel diodes based on epsilon near zero (ENZ) metal-insulator-metal (MIM) rectenna structures have the potential of disrup ...

The presence of per- and polyfluoroalkyl substances (PFAS) in the environment represents an emerging issue due to their stability, bioaccumulation potential, and risks to human and ecological well-being. There is a critical need to develop sampling methods for PFAS to assess risks and inform remedial investigations and feasibility studies (RI/FS) at locations where historical releases have elevate ...

Nutrient pollution caused by excess nitrogen and phosphorus in the water is a costly and challenging environmental problem with widespread negative health and ecological effects. During Phase I XploSafe successfully confirmed the technical feasibility of using its proprietary low-cost biodegradable sorbents to passively adsorb target nutrient ions (ammonium, nitrate, urea, and phosphate) from prim ...

Nutrient pollution caused by excess nitrogen and phosphorus in the water is a costly and challenging environmental problem with widespread potential for negative health and ecological effects. The proposed solution to this problem is the capture of ammonium, urea, nitrate and phosphate on low-cost biodegradable sorbent pellets that upon saturation, with the nutrients can be employed directly as sl ...

Methane, is the third most prevalent greenhouse gas whose atmosphere concentration is currently over 1.7 ppm. Methane is about 21 times more potent when compared to CO2. Even though its concentration in the atmosphere is more than 200 times lower than carbon dioxide, methane is responsible for 20% of the greenhouse effect. The main natural resources for methane include wetlands, termites and the o ...

Todays world and political climate lends itself to potential attacks by hostile forces and terrorists where both exterior and interior surfaces of vehicles, buildings, or equipment could become contaminated with biological warfare (BW) or chemical warfare (CW) agents. RTA Systems, Inc., proposes a system based on a two-part, water-based liquid solution that is spray-applied to contaminated surface ...

The Green Team, Inc. (tGT) will conduct Phase I research to determine characteristics of green product-service systems (GPSS) in the building products industry that effectively improve human health and the environment (e.g., improve sustainability). Knowledge of effective GPSS characteristics will be used to develop preliminary protocols for commercial GPSS authentication and the registry service. ...
