Study shows how rough microparticles can cause big problems

New research finds the surface texture of microparticles in liquid suspension can cause internal friction that significantly alters the suspension’s viscosity – effectively making the liquid thicker or thinner.

NSF Engineering Research Centers: ASSIST and FREEDM

In its first five years, ASSIST focused on building the platforms for wearable health monitoring systems and the sensors that would drive them. As those platforms have matured and the center moves into its sixth year of National Science Foundation (NSF) funding, ASSIST’s focus is transitioning to placing its technologies into clinical trials. Now in its ninth year, FREEDM hopes to demonstrate both the system it has worked to create — an improved electric grid that can handle bidirectional energy flow and integrate larger percentages of renewable energy sources — and the pieces that make it work.

Benefits of advanced wood-burning stoves greater than previously thought

A recent study out of the Department of Civil, Construction, and Environmental Engineering (CCEE) finds that advanced wood-burning stoves designed for use in the developing world can reduce air pollution more than anticipated because gaseous emissions from traditional wood stoves form more particulate matter in the atmosphere than researchers previously thought.

New technique ‘sees’ radioactive material even after it’s gone

A new technique allows researchers to characterize nuclear material that was in a location even after the nuclear material has been removed — a finding that has significant implications for nuclear nonproliferation and security applications.

Thin layers of water hold promise for the energy storage of the future

Research in the Department of Materials Science and Engineering (MSE) has found that a material that incorporates atomically thin layers of water is able to store and deliver energy much more quickly than the same material that doesn’t include the water layers. The finding raises some interesting questions about the behavior of liquids when confined at this scale and holds promise for shaping future energy-storage technologies.

New ultrasound ‘drill’ targets deep vein blood clots

Researchers at NC State and the University of North Carolina at Chapel Hill have developed a new surgical tool that uses low-frequency intravascular ultrasound to break down blood clots that cause deep vein thrombosis. The tool is the first ultrasound “drill” that can be aimed straight ahead, allowing doctors to better target clots — which holds promise for significantly reducing treatment time. To date, the technology has been tested only in synthetic blood vessels.
