How to make a "perfect" solar absorber
The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that ...
Ancient effect harnessed to produce electricity from waste heat
A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. ...
Award-winning energy harvester brings practical applications closer
Novel plastic could spur new green energy applications, 'artificial muscles'
A plastic used in filters and tubing has an unusual trait: It can produce electricity when pulled or pressed. This ability has been used in small ways, but now researchers are coaxing fibers of the material ...
Catch-release-repeat: Study reveals novel technique for handling molecules
Like vast international trading companies, biological systems pick up freight items (in the form of small molecules), transport them from place to place and release them at their proper destination. These ...
Body motion energy harvester may power medical and consumer wearable devices
A body motion energy harvester, with the flexibility and elasticity to be applied to high-flexion joints and suitable for integration with fabrics, is being developed by researchers at Sogang University in ...
Structure control unlocks magnetization and polarization simultaneously
Scientists at the University of Liverpool have controlled the structure of a material to simultaneously generate both magnetisation and electrical polarisation, an advance which has potential applications ...
New technologies harvest energy from movements, sound and more
Fed up with constantly having to recharge or replace batteries in your ever-expanding trove of electronic gadgets? The solution may be just a few steps away.
