Renewable energy: Nanotubes to channel osmotic power

The salinity difference between fresh water and salt water could be a source of renewable energy. However, power yields from existing techniques are not high enough to make them viable. A solution to this problem may now ...

UIC engineer tests improved 'icephobic' coatings

(PhysOrg.com) -- While scientists and engineers have developed several products that repel water and, to a lesser degree, snow and ice, considerable room remains for something "new and improved."

Temperature fluctuations cause excess noise

The thermal noise of the electric current has been well known for almost a century. In an article published this week in Physical Review Letters, a group of researchers from the Low Temperature Laboratory of Aalto University ...
