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 ...

Photonic 'sintering' may create new solar, electronics manufacturing technologies

03-Dec-2015

Engineers at Oregon State University have made a fundamental breakthrough in understanding the physics of photonic "sintering," which could lead to many new advances in solar cells, flexible electronics, various types of sensors and other high-tech products printed onto something as simple as a ...

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 ...

Sandcastles inspire new nanoparticle binding technique

11-Aug-2015

If you want to form very flexible chains of nanoparticles in liquid in order to build tiny robots with flexible joints or make magnetically self-healing gels, you need to revert to childhood and think about sandcastles. Researchers from North Carolina State University and the University of North ...

A most singular nano-imaging technique

Berkeley Lab's SINGLE provides images of individual nanoparticles in solution

20-Jul-2015

Just as proteins are one of the basic building blocks of biology, nanoparticles can serve as the basic building blocks for next generation materials. In keeping with this parallel between biology and nanotechnology, a proven technique for determining the three dimensional structures of individual ...

Environmentally friendly lignin nanoparticle 'greens' silver nanobullet to battle bacteria

15-Jul-2015

North Carolina State University researchers have developed an effective and environmentally benign method to combat bacteria by engineering nanoscale particles that add the antimicrobial potency of silver to a core of lignin, a ubiquitous substance found in all plant cells. The findings introduce ...

Scientists are first to see elements transform at atomic scale

Byproduct of research may lead to new way to irradiate cancer with gold-bonded isotopes

17-Jun-2015

Chemists at Tufts University's School of Arts and Sciences, collaborating with PerkinElmer and UCL (University College London), have witnessed atoms of one chemical element morph into another for the first time ever - a feat that produced an unexpected outcome that could lead to a new way to ...
