Jianhe Guo Wins MRS Graduate Student Silver Award

Texas Materials Institute and the MS&E Graduate Program are proud to announce that Ph.D. graduate and current postdoctoral fellow Jianhe Guo, received an MRS Graduate Student Silver Award for his work as a student at the 2018 Materials Research Society (MRS) Fall Meeting, held November 25-30, 2018 in Boston, Massachusetts. Jianhe was one of twenty four students to receive the Silver Award, and the only graduate student from UT Austin this year. As the top honor for graduate students in the materials research community, the award is intended to honor and encourage graduate students whose academic achievements and current materials research display a high level of excellence and distinction.

Jianhe’s Ph.D. research focused on the design and manufacturing of innovative micro/nano machines, and their applications in biomedicines. He and his co-workers exploited multiple actuation mechanisms for the development of artificial micro/nanomachines, including rotary nanomotors, chemical nanomotors, and plasmonic micro/nanomotors. The rotary nanomotors, assembled from nanoscale building blocks, have ultrasmall footprints less than 1 μm in all dimensions. They are highly reliable and can continuously operate for 80 hours with a total rotation cycles of 1.1 million. It is the record lifetime among all developed rotary micro/nanomotors. Recently, Jianhe and co-workers explored the control of mechanical propulsions from chemical reactions and successfully realized the first electric-field guided chemical nanomotors. The chemical nanomotors can accurately target and pick up cargos in microscale, transport and release them at desired locations. When assembled on a nanomechanical device, the chemical nanomotors can also harness chemical energy from the surrounding to power the mechanical motions of the device, which is the first of its kind. More recently, plasmonic nanoparticles are integrated with micro/nanomotors. Molecule behaviors can be readily monitored during the mechanical operations of the plasmonic nanomotors. Unprecedented applications have been demonstrated, including tunable release of biochemicals and acceleration of DNA capture.

We would like to congratulate Jianhe on all of his hard work and continuous drive to excel. To learn more about his research within Dr. Donglei Fan’s group, please see their website here.
