First observation of spin Hall effect in a quantum gas is step toward 'atomtronics'
12-06-2013
Researchers at the National Institute of Standards and Technology (NIST) have reported the first observation of the "spin Hall effect" in a Bose-Einstein condensate (BEC), a cloud of ultracold atoms acting as a single quantum object. As one consequence, they made the atoms, which spin like a ...

Super-nanotubes: 'Remarkable' spray-on coating combines carbon nanotubes with ceramic
19-04-2013
Researchers from the National Institute of Standards and Technology (NIST) and Kansas State University have demonstrated a spray-on mixture of carbon nanotubes and ceramic that has unprecedented ability to resist damage while absorbing laser light. Coatings that absorb as much of the energy ...
NIST research highlights promise of AFM-IR for quantitative nanoscale chemical analysis.
01-11-2012
Anasys Instruments announced a new paper authored by Dr Andrea Centrone and his colleagues at NIST published recently in Small. Dr Centrone's team reported on experiments that carefully studied the AFM-IR signal strength versus sample thickness. The experiments showed that the AFM-IR signal ...
New NIST SRM supports the fight against terrorist bombings
01-06-2012
The National Institute of Standards and Technology (NIST) has released a new standard reference material (SRM) to aid in the detection of two explosive compounds that are known to be used by terrorists. Researchers designed the new test samples to simulate the size and behavior of residues ...
Nanopower: Avoiding electrolyte failure in nanoscale lithum batteries
23-03-2012
It turns out you can be too thin—especially if you're a nanoscale battery. Researchers from the National Institute of Standards and Technology (NIST), the University of Maryland, College Park, and Sandia National Laboratories built a series of nanowire batteries to demonstrate that the ...
2 for 1: Simultaneous size and electrochemical measurement of nanomaterials
09-03-2012
Researchers at the National Institute of Standards and Technology (NIST) have done a mash-up of two very different experimental techniques—neutron scattering and electrochemical measurements—to enable them to observe structural changes in nanoparticles as they undergo an important type of ...
Slippery when stacked: NIST theorists quantify the friction of graphene
13-01-2012
Similar to the way pavement, softened by a hot sun, will slow down a car, graphene—a one-atom-thick sheet of carbon with wondrous properties—slows down an object sliding across its surface. But stack the sheets and graphene gets more slippery, say theorists at the National Institute of ...
NIST sensor improvement brings analysis method into mainstream
23-12-2011
An advance in sensor design by researchers at the National Institute of Standards and Technology (NIST) and the University of Waterloo's Institute of Quantum Computing (IQC) could unshackle a powerful, yet high-maintenance technique for exploring materials. The achievement could expand the ...
Piece of cake: Arrays of long nanotubes may help measure terahertz laser power
21-07-2011
Terahertz radiation can penetrate numerous materials—plastic, clothing, paper and some biological tissues—making it an attractive candidate for applications such as concealed weapons detection, package inspection and imaging skin tumors. However, to date there is no standard method for ...
