The objective of this effort is to demonstrate a 600 Vdc to 28 Vdc, isolated bi-directional power converter that utilizes wide bandgap semiconductors and can operate across a range of military ground vehicles.  The proposed converter is based on a modular topology that contains a combination of GaN and SiC devices, provides at least 15 kW bi-directional power flow continuously, and satisfies the ...

Rotating Detonation Combustors (RDCs) are a subject of great interest in the field of propulsion and power generation for their theoretical pressure gain and increased thermal efficiency and power density over conventional deflagrative combustors. This allows smaller, lighter and more efficient airbreathing and rocket propulsion systems, as well as conventional gas turbine based civil power gene ...

Modern lithium ion batteries are known for their poor safety performance, with many reports of battery failure and fire having been reported. One of the major causes of battery fire is from the use of flammable solvents, such as organic carbonates, as the electrolyte. These hazards have long limited the usage of batteries in dangerous conditions, such as on the battlefield. To combat this issue, t ...

Tessellated Inc and the University of Notre Dame have produced composite thin films with the highest reported tensile strengths. These films have been produced using roll-to-roll manufacturing techniques that can be adapted to current manufacturing lines. Small amounts of fillers can be added to an ultra-high molecular weight polyethylene matrix to produce thin films with high tensile strength. Th ...

To study nuclei and nuclear reactions, scientists collide stable and rare isotope heavy-ion beams like those generated at the Cyclotron Institute at Texas A&M University into targets of various elements and measure the resulting complex nuclear fragments of these collisions. The data collected from these nuclear reactions can provide information for research endeavors such as nuclear structure, nu ...

The US currently stores around 25 MtCO2/yr of anthropogenic CO2 in saline or non-oil-production reservoirs but meeting the country’s energy transition goals requires identifying total storage between two and three orders of magnitude (10–100s GtCO2) across 100s–1,000s of storage sites. The challenge is finding the 100–1000s of CO2 storage sites to make this happen. We developed new and gam ...

Large-scale data-intensive linear algebra operations are hard to scale on distributed, heterogeneous systems. Further, the data distribution across machines makes it very difficult to compose implementations as each has their own requirements. A linear algebra abstraction is needed to compose implementations. There are many use cases for such an abstraction. We will focus on simulation of differen ...

The global lubricant market size is ~$158 billion. Base-oils constitute the major component in formulated lubricants, which have uses in automotive, process oils, metal-working, marine, mining, locomotive, chainsaw, golf cart, hydraulic fluids, grease and other consumer and industrial sectors. ~97% of current base oils are petroleum derived. Their accidental release to the environment poses a sign ...
