Shape-Memory Materials Magic

Just like magic, shape-memory materials have the ability to be transformed into another shape and then return to their original shape—or in some cases even metamorphose into a third shape before returning to their original shape.  This transformation is possible because the crystalline structure of shape-memory alloys allows them to sense and respond to their environment.  Shape-memory transformation behavior can now be created by thermal, light, or chemical environments. Shape-memory alloys have been used by the research community for well over a decade to accomplish tasks that were not possible otherwise.   

Visit OSTI's Catalogue of Collections to learn about the magic happening with shape-memory technology by DOE researchers and U.S. federal agencies.

SciTech Connect is DOE's premier full-text source for research and development results in the OSTI Collections.  A myriad of DOE's research projects have utilized shape-memory materials such as endovascular therapiesenergy-efficient cooling systems that use an elastic shape-memory metal alloy as a refrigerant, and the discovery of shape-shifting plastic to produce stronger and stiffer composite parts such as carbon...

Department of Energy’s SunShot Projects

Department of Energy’s SunShot Projects

The SunShot Initiative is a collaborative national effort to make solar energy cost competitive with other forms of energy by the end of the decade.  As part of the initiative, the Department announced seven data-driven projects that will bring to light new opportunities to lower costs and advance solar energy deployment in the U.S.A.  Former Energy Secretary Steven Chu said, “Through powerful analytical tools developed by our nation’s top universities and national labs, we can gain unparalleled insight into solar deployment that will help lower the cost of solar power and create new businesses and jobs.”

The Energy Department is investing funds in these projects to assist with these new discoveries to improve solar cell efficiency and reduce costs.

DOE’s Solar Decathlon – Building the Future

DOE’s Solar Decathlon – Building the Future

The Solar Decathlon is being held September 23–October 2, 2011, at the National Mall’s West Potomac Park in Washington, DC. The event is free and open to the public.

The U.S. Department of Energy Solar Decathlon  challenges collegiate teams to design, build and operate solar-powered houses that are cost-effective, energy-efficient and attractive. The winner of the competition is the team that best blends affordability, consumer appeal and design excellence with optimal energy production and maximum efficiency.

19 teams from universities from the US and around the world are competing in the sixth running of the Solar Decathlon.  Each team’s home is monitored for its performance in five areas relating to performance and livability: comfort (maintaining comfortable temperature and humidity in the home), hot water (producing a sufficient quantity for washing and bathing), appliances (such as keeping refrigerated items at the right temperature), home entertainment (running lights, computers and other devices) and energy balance.  For the energy balance portion, homes must even out energy consumption and generation so that they use zero net energy over the course of a week. Other contests rate the teams for their communications with the public, as well as the affordability, architecture, engineering and market appeal of their homes. The winner of the competition will be announced on October 1.

To learn more about solar energy and other green energy technologies, go to the DOE Green Energy Portal and find results from valuable sources of DOE research and development information, including  DOE databases of technical reports and patents that arefiltered for green energy related subjects such as solar, hydro, geothermal, wind energy, energy storage, tidal and wave power, direct energy conversion, nuclear fuel cycle, biomass, synthetic...
