Nanofabrication
 

Nanoscale surface patterning
 

We modify the structure and energy of surfaces of various materials to obtain unusually strong water repellency, superhydrophilicity, or anisotropic friction/adhesion properties.

Nanoscale 3-D fabrication
 

We make probably the world's smallest pottery and the world's first nanofiber-stacked free-standing walls with polymer electrojetting.
