Quantum dots made from fool's gold boost battery performance


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


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


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


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


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


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 ...

NIST's 'nano-raspberries' could bear fruit in fuel cells


Researchers at the National Institute of Standards and Technology (NIST) have developed a fast, simple process for making platinum 'nano-raspberries' - microscopic clusters of nanoscale particles of the precious metal. The berry-like shape is significant because it has a high surface area, which ...


Agilent Technologies Presents Thought Leader Award to Dr. Arturo Keller

Scientist Recognized for Study of Agricultural Applications of Nanotechnology and Environmental Impact


Agilent Technologies Inc.announced that Dr. Arturo Keller has received an Agilent Thought Leader Award in support of his research on the use of nanoparticles in agriculture and the environmental consequences.Dr. Keller, who directs the Center for the Environmental Implications of Nanotechnology ...


Researchers synthesize magnetic nanoparticles that could offer alternative to rare Earth magnets


A team of scientists at Virginia Commonwealth University has synthesized a powerful new magnetic material that could reduce the dependence of the United States and other nations on rare earth elements produced by China. "The discovery opens the pathway to systematically improving the new material ...

Scientists use nanoscale building blocks and DNA 'glue' to shape 3-D superlattices

New approach to designing ordered composite materials for possible energy applications


Taking child's play with building blocks to a whole new level-the nanometer scale-scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have constructed 3D "superlattice" multicomponent nanoparticle arrays where the arrangement of particles is driven by the shape of ...
