Prashant Sarswat

---

Prashant Sarswat is an Indian-American materials scientist whose research interests include applied electrochemistry, recycling, biochemical processing, nano-manufacturing, separation science, and machine learning. He is an associate professor (research), III-investigator (University of Utah health) and Director of Materials testing and analysis facility in the Department of Materials Science & Engineering at the University of Utah, Salt Lake City.

Early Education and Career

Sarswat is from Kanpur and grew up planning to pursue an engineering career like his elders. He was an undergraduate at IIT Dhanbad, and a research fellow at IIT Kanpur in 2004-2006. He finished his Ph.D. at the University of Utah, Salt Lake City. His dissertation was focused on various electrochemical methods to fabricate thin films of absorber layers. After completing his doctorate, he became a research staff at the Department of Metallurgical Engineering at University of Utah. In 2013, he was promoted to Research Assistant Professor and subsequently to Research Associate Professor in MSE Department, College of Engineering at the University of Utah, Salt Lake City.

Research

Sarswat's discovery about waste derived light emitting diodes (LEDs) was exemplary in his field. Sarswat found a way to create LEDs from food and beverage waste. In addition to utilizing food and beverage waste that would otherwise decompose and be of no use, his development can also reduce potentially harmful waste from LEDs generally made from toxic elements. Sarswat's another outstanding research contribution was rapid synthesis of semiconductor material using microwave technology. A typical synthesis time for semiconductor/photovoltaic absorber material is around ~ 4-6 hours whereas the new method by Sarswat takes only ~ 8-12 minutes to produce semiconductor nanocrystals. Sarswat also discovered copper-zinc-antimony-sulfide (CZAS), a new semiconductor material. Sarswat's most recent research includes new methods for 2D materials synthesis, novel tellurium based topological materials and sensors, new high entropy alloys, boride based ceramics fabricated using additive manufacturing, alloys for titanium replacements, novel isotopes and rare earth elements separation technology and many new sensing technologies for healthcare monitoring. Sarswat is actively investigating new methods to recycle electronic-waste and plastics. In a DOE funded research on the possibility of converting coal-associated mineral deposits in Utah and western Colorado's Uinta Basin region into high-value metal, mineral, and non-fuel carbon-based products, Sarswat is a co-investigator.
