Researchers Achieve Historic Milestone in Energy Capacity of Supercapacitors

A landmark study led by Luis Echegoyen, Ph.D., professor emeritus at The University of Texas at El Paso, and Marta Plonska-Brzezinska, Ph.D., of the Medical University of Bialystok, Poland (not pictured), was recently featured in the journal Scientific Reports, which is published by leading research publisher Nature Portfolios. It describes how they have achieved the highest level of energy storage — also known as capacitance — in a supercapacitor ever recorded.

A University of Minnesota Twin Cities team has, for the first time, synthesized a thin film of a unique topological semimetal material that has the potential to generate more computing power and memory storage while using significantly less energy. The researchers were also able to closely study the material, leading to some important findings about the physics behind its unique properties.

The study is published in Nature Communications.

As evidenced by the United States’ recent CHIPS and Science Act, there is a ...

Thermal Cloak Passively keeps Electric Vehicles Cool in the Summer and Warm in the Winter


•Scalable, passive, all-season temperature regulation through photon recycling
•Daytime sub-ambient passive cooling by 8.0°C in summer
•Nighttime supra-ambient passive warming by 6.8°C in winter
•Fire retardant, reliable in thermal, cryogenic, vibration, and corrosive environments

When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery’s lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night...
