- A revolution in the System of Units, starring the fundamental constants
This revolution has been a long time in the making. Behind it are metrologists working in their scientific laboratories, and scientific managers in their decision-making committees. Now the moment ...
- Physicists measured something new in the radioactive decay of neutrons
A physics experiment performed at the National Institute of Standards and Technology (NIST) has enhanced scientists' understanding of how free neutrons decay into other particles. The work provides... - New and easily tunable, high-contrast scattering agent for biomedical imaging applications
The agent is made from clusters of plates of silver about 50 nanometers across and a few nanometers deep, covered with a polymeric coating - small enough, even when clustered together, to travel in...
- Electron Spin Resonance useful for exploring tiny objects
Researchers at the National Institute of Standards and Technology (NIST) have come up with a way to shrink a research instrument generally associated with large machines that make bulk measurements... - NMR 'Fingerprinting' for Monoclonal Antibodies
National Institute of Standards and Technology (NIST) researchers at the Institute for Bioscience and Biotechnology Research (IBBR) have demonstrated the most precise method yet to measure the stru...
- Nanosafety research - there's room for improvement
Empa toxicologist Harald Krug has lambasted his colleagues in the journal Angewandte Chemie. He evaluated several thousand studies on the risks associated with nanoparticles and discovered no end o... - New Method Evaluates Response to Oxidation in Live Cells
Researchers at the National Institute of Standards and Technology (NIST) have developed a new method for accurately measuring a key process governing a wide variety of cellular functions that may b... - New method of precision spectroscopy allows unprecedented accuracy
Quantum logic spectroscopy - which is closely linked with the name of the 2012 Nobel prize laureate, David J. Wineland - has been significantly extended: this new method is called "photon-recoil sp...
- NIST Launches YouTube Channel
As part of a U.S. government-wide effort to expand the amount of information available to the public about its programs, the National Institute of Standards and Technology (NIST) has created a chan...
- Nanoparticles in the Home: More and Smaller Than Previously Detected
Extremely small nanoscale particles are released by common kitchen appliances in abundant amounts, greatly outnumbering the previously detected, larger-size nanoparticles emitted by these appliance...
- New NIST Reference Material for Peptide Analysis
The National Institute of Standards and Technology (NIST) has issued its first-ever reference material designed to improve the performance and reliability of experiments to measure the masses and c... - Magnetic Computer Sensors May Help Study Biomolecules
Magnetic switches like those in computers also might be used to manipulate individual strands of DNA for high-speed applications such as gene sequencing, experiments at the National Institute of St...
