Award Data

The Thermoelectric coolers (TECs) are solid-state devices with no moving parts that provide reliable cooling power compared to traditional cooling systems such as vacuum compressors. However, their relatively high cost and low coefficient of performance (~ 0.5) have relegated them to niche applications such as small-scale portable coolers and, have yet, to be competitive from an efficiency standpo ...

The use of laser technologies and high-power electronics is rapidly being incorporated into tactical platforms for imaging, target designation, and range finding. Electronic equipment including lasers demand power from a tactical aircraft and produce large amounts of thermal energy as a waste product. Current thermal management technologies will not be sufficient for future aircraft as thermal man ...

This STTR project develops an innovative seed fabrication technology to address the fundamental size-quality limitation of gallium nitride (GaN) substratesthe indispensable key component for GaN-based vertical high-power devices. Currently, there is no viable GaN technology to realize large-area and low-defect substrates simultaneously. The technology producing 6" and larger GaN wafers results in ...

GaN power semiconductors offer a technological breakthrough for improving the performance of power electronics including power density, conversion efficiency, and reliability of power converters. These are the three most critical requirements for military, aerospace and many commercial applications. In this STTR program, Qrona Technologies will collaborate with the University of Central Florida to ...

TrueNano, Inc. will in collaboration with the University of Colorado and industry partners, develop a novel single-wafer, high-throughput hot filament CDV reactor for the growth of high quality silicon carbide (SiC) epitaxial layers, suitable for the next generation of power electronic devices and systems. This includes the design and simulation of the reactor, the development of a throughput mode ...

To meet the U.S. Navy, specifically PMA-201, need for nondestructive evaluation (NDE) of concrete, including evaluating its strength, material properties, and damage localization, Luminit, LLC, and Southern Illinois University (SIU) propose to develop a novel Concrete Materials Characterization (COMAC) system, combining several methods of concrete characterization into a single sensor/software com ...

Phase I will determine the feasibility that one-sided measurements of low power, noninvasive, nondestructive microwave energy can be used to determine the strength and condition of concrete along with relevant spatial and statistical information. We will make different types of concrete with variations in constituent ratios as test samples; use ASTM tests to destructively determine true strength; ...

Karagozian & Case Inc. and the University of Nebraska-Lincoln Department of Civil Engineering are proposing a Phase I STTR to develop a non-invasive and non-destructive methodology capable of measuring concrete material properties, including relevant spatial and statistical information associated with them, for input to hydrocode models. The solution will be both laboratory and field deployable, w ...

RDRTec proposes to design, develop, and demonstrate feasibility of a comprehensive suite of software tools and simulations that supports future Navy procurement and certification of non-cooperative sensor technologies for Detect And Avoid (DAA). These tools are an expansion, enhancement, and focusing of those already under developed as a part of RDRTec efforts on the ongoing Triton DAA radar devel ...

Texas Research Austin (TRI-Austin) will partner with the University of Texas, Austin, and will use diverse printing technologies to fabricate the components of selected battery chemistries (Li-ion, Zn-air, Zn-Ag). In the Phase I base period, each battery component will be printed with a technology that has been previously used to deposit the required material (i.e. ADM for metals, SLS for polymers ...
