Ph.D., UCLA, 2007
Nanomaterials and nanostructures; energy storage: battery, supercapacitors for various applications; energy conversion: solar cells, solar fuel, transparent electrode, light-trapping; printed electronics including nano-ink, roll-to-roll printing, flexible electronics (display, touch screen, energy), and wearable devices.
Current Research Projects
The Bing Research Group works at the intersections of three fields: Nanomaterials, energy, and flexible electronics.
Current projects in nanomaterials include synthesis and nanomanufacturing, and the structure, properties and applications of materials. Areas of interest include nanocellulose (1D) and 2D materials.
The group's work in the design of energy-related devices include investigations of sodium-ion batteries, garnet-based solid state batteries, lithium-sulfer dioxide bateries, and nanobatteries.
Professor Hu has also become well known for his creation of flexible electronic materials and devices, such as transparent "nanopaper," nanotube ink, energy textiles, and tiny, printed antennae.
Professor Hu teaches "Nanotechnology for Energy: Principles, Materials and Devices" at the undergraduate and graduate levels.
Professor Hu is also active in mentoring and outreach activities, including serving as an advisor to a Gemstone honors program team, hosting visits from high school students in Women In Engineering's LEAD Academy summer program, a partnership with Wheaton High School to create summer internships and new science lessons, and talking to visitors of all ages about materials science at Maryland Day.
