Junhong Chen Ph.D
UW-MilwaukeeJunhong Chen is a professor in the Department of Mechanical Engineering at UW-Milwaukee. He also serves as the Center Director of the Water Equipment and Policy I/UCRC. Dr.Chen has developed a unique inexpensive method of producing of nanoparticles for use in advanced technology devices — and he has used the material in devices ranging from gas and biological sensors to rechargeable batteries.
Using plasma, partially ionized gases, he creates nanocrystals on various surfaces, with precise size, form, structure and composition. His miniaturized gas sensors are important in such areas as environmental monitoring, medical diagnosis, food processing and control of other industrial processes. The material is also being used for high-capacity, lithium-ion batteries that can greatly improve the product’s voltage, life and safety.
He has also invented a dry technique to assemble nanoparticles onto various 1D or 2D nanomaterials, such as carbon nanotubes (CNTs) and graphene-based materials, with considerable control. Ongoing projects include experimental and numerical studies on plasma synthesis of nanoparticles, nanoparticle assembly, fabrication of nanomaterial-based electronic devices, CNT-nanoparticle and graphene-nanoparticle hybrid structures and their novel applications for gas sensors, water sensors, biosensors, solar cells, lithium-ion batteries, and indoor pollution control. Most of his projects are at the intersection of interesting fundamental science and industrial applications with opportunities for new discoveries, which creates an excellent vehicle for educating students.
