Profile
The technology was conceived at the University of Wisconsin-Madison lab for advanced materials for energy and electronics under the direction of Professor Michael Arnold. The impact of nanomaterials on society has often been limited because it is difficult to synthesize, purity, process, organize, and integrate nanomaterials and nanostructures. Our research especially draws from multiple disciplines to address fundamental materials challenges - in controlling the growth, processing, ordering, and heterogeneity of nanomaterials and in understanding phenomena beyond the scale of single nanostructures - that must be overcome to exploit these exciting components in technology.

Exotic new sources of free electricity: $50 billion market
High Power Energy Harvesting (HPEH) is a term beginning to be used for creation of electricity where it is needed using ambient "free" energy. That zero-pollution, high-energy conversion typically captures light (photovoltaics), heat difference (thermoelectrics and heat pumps) and movement (electrodynamics).8 Sep 2015
Energy independent vehicles emulate static off-grid experience
Off-grid electricity production on land has lessons for energy independent electric vehicles (EIVs) that come later. These generate all their own electricity from wind, waves, sun and other forms of ambient energy - free and clean.3 Aug 2015
Solar textile collaboration weaves chemistry and design
Researchers are experimenting with different ways to create solar textiles.30 Jul 2015
Ultra-thin hollow nanocages reduce platinum use in fuel cell electrode
A new fabrication technique that produces platinum hollow nanocages with ultra-thin walls could dramatically reduce the amount of the costly metal needed to provide catalytic activity in such applications as fuel cells.3 Jul 2015
New nanogenerator harvests power from rolling tires
Researchers have developed a nanogenerator that harvests energy from a car's rolling tire friction.29 Apr 2015
Better battery imaging paves way for renewable energy future
In a move that could improve the energy storage of everything from portable electronics to electric microgrids, University of Wisconsin-Madison and Brookhaven National Laboratory researchers have developed a novel X-ray imaging technique to visualize and study the electrochemical reactions in lithium-ion rechargeable batteries containing a new type of material, iron fluoride.31 Mar 2015
Discovery could yield more efficient portable electronics, solar cells
By figuring out how to precisely order the molecules that make up what scientists call organic glass, chemists have set the stage for more efficient and sturdier portable electronic devices and possibly a new generation of solar cells based on organic materials.21 Jan 2015
Breakthrough could help extend life of batteries

Save power, make power
Trisha Andrew wants to save billions of watt hours by revolutionizing, well, just about every electronic device in existence. She suggests this be done by controlling the spin on electrons, and then shutting down devices if the proper spin is absent.11 Nov 2014
Play Hockey with Team Canada Printed Electronics at PE USA
Time for some fun - and there's plenty to be had at the world's largest event on printed electronics, which will be hosted by IDTechEx in Santa Clara, CA in just a few days' time on Nov 19-20 (www.PrintedElectronicsUSA.com External Link).20 Aug 2014
Electric bacteria - it's not what it seems
For the past 10 years, scientists have been fascinated by a type of "electric bacteria" that shoots out long tendrils like electric wires, using them to power themselves and transfer electricity to a variety of solid surfaces. A team led by scientists at USC has now turned the study of these bacterial nanowires on its head, discovering that the key features in question are not pili, as previously believed.31 Mar 2014
