Carbon nanotubes: The weird world of 'remote Joule heating'
(Phys.org) -- A team of University of Maryland scientists have discovered that when electric current is run through carbon nanotubes, objects nearby heat up while the nanotubes themselves stay cool, like a ...
Nanoparticle trapped with laser light temporarily violates the second law of thermodynamics
Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding molecules. In ...
Arrays of tiny conical tips that eject ionized materials could fabricate nanoscale devices cheaply
Luis Fernando Velásquez-García's group at MIT's Microsystems Technology Laboratories (MTL) develops dense arrays of microscopic cones that harness electrostatic forces to eject streams of ions.
Move over, silicon? New transistor material tested
For the ever-shrinking transistor, there may be a new game in town. Cornell researchers have demonstrated promising electronic performance from a semiconducting compound with properties that could prove a ...
Nano-cone textures generate extremely 'robust' water-repellent surfaces
When it comes to designing extremely water-repellent surfaces, shape and size matter. That's the finding of a group of scientists at the U.S. Department of Energy's Brookhaven National Laboratory, who investigated ...
Crystals ripple in response to light: First propagating surface phonon polaritons in a van der Waals crystal
Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be "tuned" to ...
New method for measuring temperature of nanoscale objects discovered
Temperature measurements in our daily life are typically performed by bringing a thermometer in contact with the object to be measured. However, measuring the temperature of nanoscale objects is a much more ...
Researchers develop new method to control nanoscale diamond sensors
Diamonds may be a girl's best friend, but they could also one day help us understand how the brain processes information, thanks to a new sensing technique developed at MIT.
