Soft lossy viscoelastic polymers can dissipate significant amounts of energy in the form of heat when subjected to dynamic mechanical stimuli. As a result, structures comprised of such lossy materials may heat up considerably when excited by loads at a frequency that approaches one of ... Read More

State of the art measurements of permanent electric dipoles (EDM) measure accumulated phase in spin-polarized gases over hundreds of seconds and are exquisitely sensitive to magnetic field inhomogeneities. The search for the neutron's EDM at Los Alamos National Laboratory (nEDM@LANL) ... Read More

Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... Read More

Recent events underscore the importance of rapid diagnostic tests for detecting viruses such as the SARS-CoV-2 coronavirus or for screening cancer biomarkers. Many fluidic-based diagnostics applications require careful control of chemical and biological species concentrations. In this ... Read More

Working fluids (engine oil, transmission fluid, hydraulic fluid, coolants, etc.) become contaminated in use. To ensure that the equipment is not damaged by the contaminated fluid, the fluid is typically removed and replaced periodically. For large groups of machines, the used fluid is ... Read More

During the biopharmaceutical manufacturing process, proteins stored in aqueous solutions are frozen and thawed. Frozen aqueous solutions provide an excellent medium for storing and transporting the protein without degradation. In this work, the freezing and thawing of an aqueous solution ... Read More

Hemolysis caused by flow-induced mechanical damage to red blood cells is a concern in devices that involve transporting blood. Mathematical models have been proposed to estimate red blood cell damage in blood flow. We used hemolysis mathematical models to evaluate the effect of ... Read More

Advancements in simulation technology are supported by rapidly evolving enablers such as Cloud infrastructure, high-performance computing platforms (on & off-premises), on-demand Machine Learning systems, and secure multi-user environments. These advancements provide an opportunity ... Read More

Radial fins are widely used in industrial applications to enhance heat transfer. Exact solutions are available for radial fins of simple profiles such as rectangular, concave and convex parabolic, hyperbolic and triangular. However, such solutions may be cumbersome for use in everyday ... Read More

With the anticipated effects of global climate change upon us, induced by egregious CO2 emissions, it is imperative to implement technologies to close the carbon cycle. One potential technique to do this is storing the energy from intermittent sources (e.g. solar, wind, hydro) in the ... Read More
