Mixing nanoparticles to make multifunctional materials

Posted: 20 Oct 2013 01:05 PM PDT

Scientists have developed a general approach for combining different types of nanoparticles to produce large-scale composite materials. The technique opens many opportunities for mixing and matching particles with different magnetic, optical, or chemical properties to form new, multifunctional materials or materials with enhanced performance for a wide range of potential applications.

Market bubbles may be predictable, controllable

Posted: 18 Oct 2013 10:23 AM PDT

An international team of chaos researchers say that extreme events like market crashes and super-waves at sea, which they call "dragon kings," are less random than had been thought and that, in a simple experiment at least, they can be anticipated and controlled.

Wrangling flow to quiet cars and aircraft

Posted: 18 Oct 2013 10:20 AM PDT

With the use of high voltage equipment, very small plasmas can be used to manipulate fluid flows. In recent years, the development of devices known as plasma actuators has advanced the promise of controlling flows in new ways that increase lift, reduce drag and improve aerodynamic efficiencies -- advances that may lead to safer, more efficient and more quiet land and air vehicles in the near future.
