Tiny laser sensor heightens bomb detection sensitivity
New technology under development at the University of California, Berkeley, could soon give bomb-sniffing dogs some serious competition.
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 ...
Solution to two long-standing mysteries of cuprate superconductivity found
Scientists seeking to understand the intricacies of high-temperature superconductivity—the ability of certain materials to carry electrical current with no energy loss—have been particularly puzzled by ...
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 ...
Your T-shirt's ringing: Telecommunications in the spaser age
(Phys.org) —A new version of "spaser" technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.
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 ...
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 ...
Nanoscale pillars could radically improve conversion of heat to electricity
University of Colorado Boulder scientists have found a creative way to radically improve thermoelectric materials, a finding that could one day lead to the development of improved solar panels, more energy-efficient ...
