We discover, design, and characterize
the advanced materials humanity needs.
At UC San Diego, we leverage our cross-disciplinary expertise to discover, design, and characterize advanced materials needed to address global societal challenges. Our materials work is relevant for developing zero- and low-carbon energy and transportation systems; cost-effective healthcare advances; solutions for natural-resource sustainability; and next-generation information technologies.
This work is grounded in our ability to control materials at the level of atoms and electrons.
Equally important, we are world-leaders in characterizing the structure and function of materials at the nanoscale level using a suite of cutting-edge analytical and theoretical tools, many of which we have developed here at UC San Diego.
A new technology could dramatically improve the safety and performance of lithium-ion batteries that operate with gas electrolytes at ultra-low temperatures. By keeping electrolytes from vaporizing, the technology can prevent pressure buildup inside the battery that leads to swelling and explosions. Full Story
Rapid COVID-19 tests are on the rise to deliver results faster to more people, and scientists need an easy, foolproof way to know that these tests work correctly and the results can be trusted. Nanoparticles that pass detection as the novel coronavirus could be just the ticket. Such coronavirus-like nanoparticles, developed by nanoengineers at the University of California San Diego, would serve as something called a positive control for COVID-19 tests. Full Story
Weakness is strength for this low-temperature battery
February 25, 2021
Nanoengineers at the University of California San Diego have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte holds on to lithium ions, the better. By using such a weakly binding electrolyte, the researchers developed a lithium metal battery that can be repeatedly recharged at temperatures as low as -60 degrees Celsius—a first in the field.
