Dr. Guihua Yu: Hybrid Nanomaterial Systems, Energy Storage Devices, Electronic Nanosystems

Assistant Professor Guihua Yu, of the Mechanical Engineering Department at The University of Texas at Austin, focuses on rational design and synthesis of functional nanomaterials, fundamental understanding of their chemical and physical properties, and development of large-scale assembly and integration strategies to enable their technologically important applications in energy science, electronics, and nanobiotechnology. He has published over 25 papers in leading scientific journals including Science, Nature Nanotechnology, PNAS, Nano Letters, etc, and many of his works have been featured in top scientific media, such as Nature News, Science News, ABC, Forbes, Discover, R&D Magazine, MIT Technology Review, Popular Science, etc. Currently, his main research interests include:

  • Nanostructures-enabled energy storage and conversion devices: next-generation lithium batteries, electrochemical supercapacitors, thermoelectric devices, microbial fuel cells
  • Self-assembled Nanosystems for flexible electronics and optoelectronics
  • Hybrid inorganic-organic nanomaterial systems for functional interface with biological systems

The nature of research program in Dr. Yu’s group is highly interdisciplinary, and it explores the basic principles in chemistry, physics, materials science and engineering to enable both fundamental understanding of novel materials with designed nano-architectures, and development of their technological applications.

Developed a scalable and versatile synthesis of multifunctional polyaniline (PAni) hydrogel with excellent electronic conductivity and electrochemical properties. With high surface area and 3D porous nanostructures, the PAni hydrogels demonstrated potential as high-performance supercapacitor electrodes with high specific capacitance, excellent rate capability and cycling stability. The PAni hydrogels can also function as glucose oxidase sensors with fast response time and superior sensitivity. The scalable synthesis and excellent electrode performance of the PAni hydrogel make it an attractive candidate for bioelectronics and future-generation energy storage electrodes.
