About
Keith Johnston is the Cockrell Family Dean's Chair in Engineering Excellence at the University of Texas at Austin's McKetta Department of Chemical Engineering. His research focuses on combining materials chemistry, colloid and interface science, and polymer science to develop applications across various fields, including drug delivery, biomedical imaging and therapy, electrocatalysis in energy storage, and subsurface energy production. He has discovered or co-discovered various nanomaterials such as water/CO2 microemulsions, silicon nanowires, and highly active perovskite electrocatalysts and supercapacitors. Johnston has made significant contributions to nanotechnology for subsurface green energy production, which encompasses CO2 sequestration, improved oil recovery, magnetic nanomaterials for electromagnetic imaging of reservoirs, nanocapsule delivery, and greener fracturing with low water utilization. His work integrates materials chemistry, colloid and interface science, and polymer science to guide the development of innovative solutions in these areas. He holds a Ph.D. from the University of Illinois (1981) and a B.S. from the University of Michigan (1977). Johnston has received numerous awards and honors, including being named a fellow of the American Institute of Medical and Biological Engineers in 2013, election to the National Academy of Engineering in 2011, and recognition as one of the '100 Chemical Engineers of the Modern Era' by the American Institute of…

) after months of storage and operation in bacteria-containing river water. The ABH platform offers reduced energy and chemical demands for point-of-use water treatment technologies in remote areas and emergency rescue applications.
Biomimetically Assembled Sponge‐Like Hydrogels for Efficient Solar Water Purification
Advanced Functional Materials · 2023-05-19 · 76 citations
articleOpen accessAbstract Hydrogel‐based evaporators for interfacial solar vapor generation (SVG) have emerged as a promising and sustainable strategy for freshwater production. Nevertheless, developing a green and simple approach in the fabrication of porous hydrogel‐based evaporators with tunable porous structures and superior mechanical properties continues to be a challenge. Herein, cryo‐assembled templating and polymerization (CTP) is proposed as an ecological, simple yet effective approach to synthesizing…
