Evolution inspires more efficient solar cell design: Geometric pattern maximizes time light is trapped in solar cell
(Phys.org)—The sun's energy is virtually limitless, but harnessing its electricity with today's single-crystal silicon solar cells is extremely expensive—10 times pricier than coal, according to some ...
Atoms at negative absolute temperature: The hottest systems in the world
(Phys.org)—In cold regions on earth, negative temperatures on the Fahrenheit or Celsius scale can often occur in winter; in physics, however, they were so far impossible. On the absolute temperature scale ...

Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
On quantum scales, there are many second laws of thermodynamics
New research from UCL and the Universities of Gdansk, Singapore, and Delft has uncovered additional second laws of thermodynamics which complement the ordinary second law of thermodynamics, one of the most ...
From seawater to freshwater with a nanotechnology filter
In this month's Physics World, Jason Reese, Weir Professor of Thermodynamics and Fluid Mechanics at the University of Strathclyde, describes the role that carbon nanotubes (CNTs) could play in the desalination of wat ...
