The Clemson Nanomaterials Institute specializes in studying the properties and applications of nanomaterials. Our work combines science and engineering to improve energy storage and energy generation devices, as well as studying fundamental aspects of nanoscale systems. In conjunction with the Nano-Bio laboratory overseen by Dr. Ramakrishna Podila, the effects of nanomaterials on living systems is also investigated.  Some of the areas of research include:

-Implementing graphene and carbon nanotubes to improve performance in energy storage systems such as lithium-ion batteries and supercapacitors.

-Using graphene in triboelectric nanogenerators.

-Scalable synthesis methods for nanomaterials.

-Studying the effects of intrinsic and extrinsic defects on the electronic properties of nanomaterials.

-Investigating the Raman modes of 2-D materials

-Non-linear optical properties of nanomaterials

-Mechanical properties of carbon nanotube arrays

For more information, visit the research section in the tabs above. We are always looking for motivated students (graduate and undergrad) who are willing to learn and work on several challenging projects.
