Getting better all the time: JILA strontium atomic clock sets new records

23-Apr-2015

In another advance at the far frontiers of timekeeping by National Institute of Standards and Technology (NIST) researchers, the latest modification of a record-setting strontium atomic clock has achieved precision and stability levels that now mean the clock would neither gain nor lose one ...

New materials discovered to detect neutrons emitted by radioactive materials

06-Mar-2015

Scientist Christopher Lavelle of the Johns Hopkins University Applied Physics Laboratory, together with a team of researchers from the University of Maryland and the National Institute of Standards and Technology, has successfully shown that boron-coated vitreous carbon foam can be used in the ...

Liquids and glasses relax, too. But not like you thought.

20-Jan-2015

A new insight into the fundamental mechanics of the movement of molecules published by researchers at the National Institute of Standards and Technology (NIST) offers a surprising view of what happens when you pour a liquid out of a cup. More important, it provides a theoretical foundation for a ...

New NIST metamaterial gives light a one-way ticket

07-Jul-2014

The light-warping structures known as metamaterials have a new trick in their ever-expanding repertoire. Researchers at the National Institute of Standards and Technology (NIST) have built a silver, glass and chromium nanostructure that can all but stop visible light cold in one direction while ...

Don't blink! NIST studies why quantum dots suffer from 'fluorescence intermittency'

30-May-2014

Researchers at the National Institute of Standards and Technology (NIST), working in collaboration with the Naval Research Laboratory, have found that a particular species of quantum dots that weren't commonly thought to blink, do. So what? Well, although the blinks are short—on the order of ...

From separation to transformation: Metal-organic framework shows new talent

28-May-2014

This gift from science just keeps on giving. Measurements taken at the National Institute of Standards and Technology (NIST) show why a material already known to be good at separating components of natural gas also can do something trickier: catalysis. The discovery is a rare example of a ...

New microscope sees what others can't

12-May-2014

Microscopes don't exactly lie, but their limitations affect the truths they can tell. For example, scanning electron microscopes (SEMs) simply can't see materials that don't conduct electricity very well, and their high energies can actually damage some types of samples. In an effort to extract a ...

A new US time standard

NIST-F2 atomic clock

07-Apr-2014

The U.S. Department of Commerce's National Institute of Standards and Technology (NIST) has officially launched a new atomic clock, called NIST-F2, to serve as a new U.S. civilian time and frequency standard, along with the current NIST-F1 standard. NIST-F2 would neither gain nor lose one second ...

Simple microfluidic devices now have valves

04-Apr-2014

Researchers at the National Institute of Standards and Technology (NIST) have added yet another innovation—miniature valves—to their ever-growing collection of inexpensive, easy-to-manufacture and highly efficient microfluidic devices made from plastic films and double-sided tape. Traditionally, ...

'Quantum droplet' in semiconductor

28-Feb-2014

JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet. Quasiparticles are composites of smaller particles that can be created inside solid materials and ...
