New ultracapacitor recharges in under a millisecond
Applied physicists create building blocks for a new class of optical circuits
Imagine creating novel devices with amazing and exotic optical properties not found in Nature -- by simply evaporating a droplet of particles on a surface.
Understanding tiny reactions: Cold atoms and nanotubes come together in atomic 'black hole'
(PhysOrg.com) -- Carbon nanotubes, long touted for applications in materials and electronics, may also be the stuff of atomic-scale black holes.
Scientists discover world's smallest superconductor
Scientists have discovered the world's smallest superconductor, a sheet of four pairs of molecules less than one nanometer wide. The Ohio University-led study, published Sunday as an advance online publication ...
Nano-foundry technique yields ultra-durable probes from diamond
(PhysOrg.com) -- When a team of university and industry researchers tried a novel, foundry-style mold-filling technique to make nanoscale devices, they realized they had discovered a gem.
Water droplets shape graphene nanostructures
A single-atom-thick sheet of carbon, like those seen in pencil marks -- offers great potential for new types of nanoscale devices, if a good way can be found to mold the material into desired shapes.
Small optical force can budge nanoscale objects
(PhysOrg.com) -- Engineering researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers.
Scientists solve decade-long mystery of nanopillar formations
Scientists at the California Institute of Technology have uncovered the physical mechanism by which arrays of nanoscale pillars can be grown on polymer films with very high precision, in potentially limitless ...

A 'cloaking device' -- it's all done with mirrors
(PhysOrg.com) -- Somewhat the way Harry Potter can cover himself with a cloak and become invisible, Cornell researchers have developed a device that can make it seem that a bump in a carpet -- or, indeed, ...
Researchers discover a potential on-off switch for nanoelectronics
As electronic circuits shrink from finely etched lines in silicon wafers to nearly elusive proportions, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Columbia University ...
Knowing when to fold: Engineers use 'nano-origami' to build tiny electronic devices (Video)
(PhysOrg.com) -- Folding paper into shapes such as a crane or a butterfly is challenging enough for most people. Now imagine trying to fold something that's about a hundred times thinner than a human hair ...
Researchers tune friction in ionic solids at the nanoscale
Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at the Department of Energy's ...
