A novel graphene quantum dot structure takes the cake

27-Aug-2018

In a marriage of quantum science and solid-state physics, researchers at the National Institute of Standards and Technology (NIST) have used magnetic fields to confine groups of electrons to a series of concentric rings within graphene, a single layer of tightly packed carbon atoms. This tiered ...

Connecting the (Nano)dots

Big-picture thinking can advance nanoparticle manufacturing

24-Aug-2018

Nanoparticle manufacturing, the production of material units less than 100 nanometers in size (100,000 times smaller than a marble), is proving the adage that “good things come in small packages.” Today’s engineered nanoparticles are integral components of everything from the quantum dot ...

Trapping ions in graphene

Simulating simple logic for nanofluidic computing

02-Jul-2018

Invigorating the idea of computers based on fluids instead of silicon, researchers at the National Institute of Standards and Technology (NIST) have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene (a ...

Long-Sought Workaround to Helium Shortage?

Neutron Detection Method

12-Jun-2018

Doctors use X-rays to see inside people, and scientists use neutrons to peer inside advanced materials and devices such as fuel cells to better understand and improve them. But a critical shortage of a rare form of helium used for detecting neutrons—which are difficult to spot directly—threatens ...

Psst! A whispering gallery for light boosts solar cells

17-Apr-2018

Trapping light with an optical version of a whispering gallery, researchers at the National Institute of Standards and Technology (NIST) have developed a nanoscale coating for solar cells that enables them to absorb about 20 percent more sunlight than uncoated devices. The coating, applied with a ...

Unexpected effect could lead to lower-power memory, computing devices

20-Mar-2018

An unexpected phenomenon known as zero field switching (ZFS) could lead to smaller, lower-power memory and computing devices than presently possible. The image shows a layering of platinum (Pt), tungsten (W), and a cobalt-iron-boron magnet (CoFeB) sandwiched at the ends by gold (Au) electrodes on ...

Superconducting synapse may be missing piece for 'artificial brains'

30-Jan-2018

Researchers at the National Institute of Standards and Technology (NIST) have built a superconducting switch that "learns" like a biological system and could connect processors and store memories in future computers operating like the human brain. The NIST switch is called a synapse, like its ...

Atomic blasting creates new devices to measure nanoparticles

18-Dec-2017

Like sandblasting at the nanometer scale, focused beams of ions ablate hard materials to form intricate three-dimensional patterns. The beams can create tiny features in the lateral dimensions--length and width, but to create the next generation of nanometer-scale devices, the energetic ions must ...

Channeling graphene to understand filtration and ion transport into cells

12-Dec-2017

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells. ...

Color me purple, or red, or green, or ...

10-Nov-2017

Imagine a miniature device that suffuses each room in your house with a different hue of the rainbow--purple for the living room, perhaps, blue for the bedroom, green for the kitchen. A team led by scientists at the National Institute of Standards and Technology (NIST) has, for the first time, ...
