Biography

Radha Kishan Motkuri, PhD, is a senior chemical engineer/material scientist with Pacific Northwest National Laboratory (PNNL). Dr. Motkuri has over 23 years of experience in inorganic and materials chemistry with an emphasis on nanoporous materials. More specifically, his work has focused on nanoporous materials including metal-organic frameworks (MOFs), covalent organic frameworks, covalent organic polymers, porous aromatic frameworks, hierarchical porous carbons, zeolites, and mesoporous silica for potential applications including sorption/capture, separation, catalysis, detection, and sensing.

Motkuri’s research on nanoporous materials for potential applications, including adsorption cooling/refrigeration using fluorocarbons and water, is disseminated through various publications, patents, and awards. He was integral to developing thermal vapor-compression technology that runs off any low-grade heat source, called MARCool, for which he received a 2017 R&D 100 Award. His research for the AirJoule Self-Regenerating Dehumidifier—a heating, ventilation, and air conditioning component that recycles the heat it generates by removing water from the air—is also widely recognized and was awared as a 2021 R&D 100 Bronze award.

Motkuri and his team are currently developing two technologies to help locate and clean up hazardous perfluoroalkyl and polyfluoroalkyl substances (PFAS): a sensitive, portable sensor to detect PFAS in the field, and an innovative technology to capture PFAS. The latter could aid cleanup efforts aimed at protecting groundwater to help protect communities and ecosystems from PFAS. The fast PFAS sensor work was selected as a 2021 R&D 100 Finalist.

Motkuri earned his PhD in chemistry from the University of Hyderabad, dealing with nanoporous materials for supramolecular chemistry and catalysis applications. After he completed his Alexander von Humboldt fellowship on rotaxanes and supramolecular chemistry, he finished his postdoctoral research on molecular motors and boron chemistry.
