A bi-weekly event to present and discuss issues related to developments, applications and commercialization of nanotechnology.
NANO-DEVICES FOR ENHANCED COOLING AND EXPLOSIVES SENSING
Speaker: Debjyoti Banerjee, Ph.D.
Assistant Professor of Mechanical Engineering
Texas A&M University
(VIDEO CONFERENCED FROM TEXAS A & M UNIVERSITY)
Abstract: 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:
Debjyoti Banerjee, Ph.D.
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.).
