Lasers etch a 'perfect' solar energy absorber

The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar power generators.

Water-shedding surfaces can be made to last

Steam condensation is key to the worldwide production of electricity and clean water: It is part of the power cycle that drives 85 percent of all electricity-generating plants and about half of all desalination plants globally, ...

World's first magnetic soap produced

Scientists from the University of Bristol have developed a soap, composed of iron rich salts dissolved in water, that responds to a magnetic field when placed in solution. The soap's magnetic properties were proved with neutrons ...

Bending light the 'wrong' way

(PhysOrg.com) -- Scientists have tried this with sophisticated meta-materials, but at the Vienna University of Technology (TU Vienna) it has now been done with simple metals; materials with a negative refractive index bend ...

Researchers create switchable mirrors from liquid metal

Researchers have developed a way to dynamically switch the surface of liquidmetal between reflective and scattering states. This technology could one day be used to create electrically controllable mirrors or illumination ...
