Catalyst could make production of key chemical more eco-friendly

11-Apr-2016

The world has more carbon dioxide than it needs, and a team of Brown University chemists has come up with a potential way to put some of it to good use. The researchers developed a new composite catalyst using nitrogen-rich graphene dotted with copper nanoparticles. A study, published in the ...

A movie of the microworld: Physicists create nanoparticle picture series

07-Apr-2016

Think of it as a microscopic movie: A sequence of X-ray images shows the explosion of superheated nanoparticles. The picture series reveals how the atoms in these particles move, how they form plasma and how the particles change shape. The method of taking these pictures is a collaborative ...

Scientists film exploding nanoparticles

Imaging nanoscale dynamics with unparalleled detail and speed

08-Feb-2016

Using a super X-ray microscope, an international research team has “filmed” the explosion of single nanoparticles. The team led by Tais Gorkhover from Technische Universität Berlin, currently working at the SLAC National Accelerator Laboratory in the U.S. as a fellow of the Volkswagen Foundation, ...

In plasmonics, 'optical losses' could bring practical gain

28-Jan-2016

What researchers had thought of as a barrier to developing advanced technologies based on the emerging field of plasmonics is now seen as a potential pathway to practical applications in areas from cancer therapy to nanomanufacturing. Plasmonic materials contain features, patterns or elements ...

Shaking the nanomaterials out

15-Dec-2015

Purifying water and greening nanotechnology could be as simple as shaking a vial of water and oil. At least that's the case for a new method to clean contaminated water full of unwanted nanomaterials. Nano implies small--and that's great for use in medical devices, beauty products and ...

Nanoscale drawbridges open path to color displays

First method for reversible color changes with metal nanoparticles

08-Dec-2015

A new method for building "drawbridges" between metal nanoparticles may allow electronics makers to build full-color displays using light-scattering nanoparticles that are similar to the gold materials that medieval artisans used to create red stained-glass. "Wouldn't it be interesting if we ...

Quantum dots made from fool's gold boost battery performance

13-Nov-2015

If you add quantum dots - nanocrystals 10,000 times smaller than the width of a human hair - to a smartphone battery it will charge in 30 seconds, but the effect only lasts for a few recharge cycles. However, a group of researchers at Vanderbilt University found a way to overcome this problem: ...

These microscopic fish are 3-D-printed to do more than swim

27-Aug-2015

Nanoengineers at the University of California, San Diego used a 3D printing technology they developed to manufacture multipurpose fish-shaped microrobots that swim around efficiently in liquids, are chemically powered by hydrogen peroxide and magnetically controlled. These proof-of-concept ...
