Optical BioMEMS Microfluidic Technologies for Hand-Held, Point-of-Care, Medical Devices
23 Nov 2009 | | Contributor(s):: James Leary
Portable, point-of-care, medical diagnostic devices could provide an important new component in more cost-effective healthcare delivery. Rapid measurements of blood samples during an examination within a doctor’s office or in the field, could allow immediate appropriate treatment of medical...
Metal Oxide Nanowires as Gas Sensing Elements: from Basic Research to Real World Applications
out of 5 stars
21 Sep 2009 | | Contributor(s):: andrei kolmakov
Quasi 1-D metal oxide single crystal chemiresistors are close to occupy their specific niche in the real world of solid state sensorics. Potentially, the major advantage of this kind of sensors with respect to available granular thin film sensors will be their size and stable, reproducible and...
Experiment vs. Modelling: What's the problem?
10 Aug 2009 | | Contributor(s):: William L. Barnes
Progress in plasmonics has been greatly assisted by developments in experimental techniques and in numerical modelling. This talk will look at some of the difficulties that emerge when comparisons are made between experiment and theory. Through the use of four examples I will illustrate what some...
Nanotribology, Nanomechanics and Materials Characterization Studies
08 Jun 2009 | | Contributor(s):: Bharat Bhushan
Fundamental nanotribological studies provide insight to molecular origins of interfacial phenomena including adhesion, friction, wear and lubrication. Friction and wear of lightly loaded micro/nano components are highly dependent on the surface interactions (few atomic layers). Nanotribological...
The Challenges of Micro-System Product Development
05 Jun 2009 | | Contributor(s):: James J. Allen
This talk will discuss the historical development of micro‐system technology, the products that have been developed and the challenges to development of a reliable product.

Engineering the Classroom: Engineering science as the core for technology teacher education for the 21st century
28 Apr 2009 | | Contributor(s):: Michael De Miranda, National Center for Learning & Teaching in Nanoscale Science & Engineering
This NCLT seminar presentation will report on content analysis research of pre-service teacher/engineering science students’ ability to conceptualize, design, and evaluate student design brief solutions in high school technology classes. This research is just a part of a larger challenge within...
Renewable Solar Energy: Has the Sun Finally Risen on Photovoltaics?
10 Apr 2009 | | Contributor(s):: Mark R. Pinto
After a review of the overall renewable energy landscape,including the central role of economics, we present here the case thatPV is on the verge of becoming a major source of electrical powerthrough a principle similar to that which underlies the 50 year progressof IC technology - the reduction...
MCW07 Exploring Trends in Conductance for Well-Defined Single Molecule Circuits
04 Apr 2009 | | Contributor(s):: Mark S Hybertsen
In our recent research, we have been able to measure and characterize the impact of intrinsic molecular properties on the conductance of single molecule circuits formed with amine-gold linkages. In this talk, I will review the experiments and the physical picture of the junction based on the...
Quantitative, Kinetic Models of Cellular Circuits
04 Apr 2009 | | Contributor(s):: Michael R. Brent
Living cells contain complex, analog circuits that regulate the rate at which each gene produces its product. The kinetic properties of these circuits enable cells to respond to changes in their environments and thus to survive, reproduce, and compete. For decades, molecular biologists have been...
Aluminum: a safe, economical, high energy density material for energy storage, transport and splitting water to make hydrogen on demand
30 Mar 2009 | | Contributor(s):: Jerry M. Woodall
In 1968, a team lead by the author discovered that liquid gallium saturated with aluminum at room temperature would split water into hydrogen gas, alumina and heat. More recently his current team has discovered that bulk, solid Al rich alloys will also split water in the same manner. Since 1) the...
