Some Lessons on Entrepreneurship in Nanotechnology (and, Mechanical Engineers do 'nano', too)
18 Feb 2016 | Online Presentations | Contributor(s): Timothy S Fisher
Professor Tim Fisher will talk about his brief excursion into starting (and stopping) a company, with a focus on lessons learned that are related to education and academic research. He will also try to convince a likely skeptical audience that mechanical engineers have something valuable to contribute to nanotechnology.

Timothy S. Fisher (PhD in Mechanical Engineering, 1998, Cornell) was born in Aurora, IL. He joined the Purdue’s School of Mechanical Engineering and Birck Nanotechnology Center in 2002 after several years at Vanderbilt University. In 2013 Purdue named him the James G. Dwyer Professor in Mechanical Engineering. He is Director of the Center for Integrated Thermal Management of Aerospace Vehicles (CITMAV), funded by the Air Force Research Laboratory and key industrial partners. He is also an Adjunct Professor in the International Centre for Materials Science at the Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) and co-directs the JNCASR-Purdue Joint Networked Centre on Nanomaterials for Energy. From 2009 to 2011, he served as a Research Scientist at the Air Force Research Laboratory’s newly formed Thermal Sciences and Materials Branch of the Materials and Manufacturing Directorate. Prior to his graduate studies, he was employed from 1991 to 1993 as a design engineer in Motorola's Automotive and Industrial Electronics Group. His research has included efforts in simulation and measurement of nanoscale heat transfer, coupled electro-thermal effects in semiconductor and electron emission devices, nanoscale direct energy conversion, molecular electronics, microfluidic devices, biosensing, hydrogen storage, and related computational methods ranging from atomistic to continuum scales.

Notes on the quantum of thermal conductance
The following is a dump from LaTex, just to see what happens…
In this module we derive the quantum of thermal conductance, and along the way, concepts related to phonon density of states and spatial dimensionality are discussed and applied. The end result is a simple...

Calculation of Fin Temperature for Adiabatic Tip and Infinite Fins
The following CDF tool calculates the normalized fin temperature (θ(x) / θbase) for two cases:
Case 1: Adiabatic fin tip
Case 2: Infinitely long fin
In both cases, the cross sectional area of the fin is assumed...
