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 ...

Operational experts collect recorded data about emerging tactics, techniques, and procedures (TTPs) from sources such as live and virtual training exercises, and numerous test and evaluation simulations. However, instructional designers cannot easily reuse the recorded data to create new training. Without sufficient access to operational experts, expert knowledge is inaccessible and fragmented, of ...

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 ...

Naval aircraft components are routinely made of 7000 series aluminum alloys due to their strength, weight and fatigue properties. Present Additive Manufacturing (AM) processes falls short of producing 7000 series Al alloys successfully due to lack of porosity, thermal and composition control. In-situ methods implemented to date largely only yield information about the component surface and other m ...

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 ...

Storagenergy Technologies Inc. proposes to develop an all solid-state battery (ASSB) which can be made by a high-speed AMtechnology.

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 ...
