Quantum Optical Cooling of Nanoparticles

Physicists develop new method

09-Apr-2019

When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, i.e. to cool it as close as possible to absolute zero temperature. ...

Layered liquids arrange nanoparticles into useful configurations

Theoretical approach for assembling nanoparticles uses an idea similar to separated vinaigrettes

28-Mar-2019

Materials scientists at Duke University have theorized a new "oil-and-vinegar" approach to engineering self-assembling materials of unusual architectures made out of spherical nanoparticles. The resulting structures could prove useful to applications in optics, plasmonics, electronics and ...

Fish-inspired material changes color using nanocolumns

22-Mar-2019

Inspired by the flashing colors of the neon tetra fish, researchers have developed a technique for changing the color of a material by manipulating the orientation of nanostructured columns in the material. "Neon tetras can control their brightly colored stripes by changing the angle of tiny ...

Nanotechnology and sunlight clear the way for better visibility

07-Mar-2019

A new coating developed by ETH researchers prevents fogging on transparent surfaces. Rather than using electricity, the coating relies on sunlight to heat the surface. Anyone who skis, wears glasses, uses a camera or drives a car is familiar with the problem: if you come into a humid environment ...

Examining silver nanoparticles in natural environments

28-Feb-2019

Thanks to their antibacterial properties, the particles are used in many products. Their effect on the environment is largely unexplored. This is mainly due to the lack of suitable analytical methods. Researchers from the Resolv Cluster of Excellence at Ruhr-Universität Bochum have developed a ...

Adding a porous envelope to aluminum plasmonics

Gas-trapping framework married to light-powered nanocatalysts

13-Feb-2019

When Rice University chemist and engineer Hossein Robatjazi set out to marry a molecular sieve called MOF to a plasmonic aluminum nanoparticle two years ago, he never imagined the key would be the same process nature uses to petrify wood. In a new paper Robatjazi and co-authors with Rice's ...
