Nano-devices for enhanced cooling and explosives sensing

San Marcos, TX | Posted on March 19th, 2007

Our research efforts are in: (a) cooling technologies, and (b) nano-lithography.

In the thermal area - we are investigating micro-scale heat transfer phenomena in boiling. Micron-scale features in boiling cause the formation of "cold spots". These cold-spots are able to transmit almost 60-90% of the total heat transfer.

Using Carbon Nano-Tube coated surfaces cooling was enhanced by 30-300%, probably due to enhancement of these cold spots in boiling. The enhancement was found to depend on the height of the Carbon Nanotubes, wall superheat and liquid subcooling. The applications are in materials processing, thermal management (cooling) and cryogenics. We have also demonstrated cooling enhancement by 8-10% using nanofluids.

DPN™ (Dip Pen Nanolithography) is a versatile technology that leverages microfluidic ink delivery systems with Scanning Probe Microscopy. The applications are in biotechnology, photo-mask repair, molecular electronics, nano-electronics and mask-less lithography. In earlier studies the DPN process was enhanced through the development of commercial microfluidic devices called "Inkwells™". We are currently developing the next generation microfluidic devices for DPN (e.g.,Fountain Pen Nanolithography). The applications are in nano-catalysis, combinatorial nano-synthesis, bio-nanotechnology (e.g., cancer nanotechnology) and nano-sensors for homeland security, biosecurity and explosives detection (e.g., "nano-nose" and "nano-tongue").

Bio: Dr. Banerjee received his Ph.D. in Mechanical Engineering from UCLA (with minor in MEMS) and received the "2001 Best Journal Paper Award" from the ASME Heat Transfer Division (HTD). He received three M.S. degrees and was invited to the membership of four national academic honor societies. He attended the Indian Instituteof Technology (I.I.T.), Kharagpur for his Bachelor of Technology (Honors). Most recently Dr. Banerjee worked as a Manager of the Advanced Research & Technology (ART) group at Applied Biosystems Inc. ($2B annual revenue), CA, where he managed a group of 10 engineers and scientists (6 Ph.D.).
