Image: Cutaway view of nanoparticles in a neural cell

NIST's Precision Imaging Facility (PIF) in Boulder, Colo., provides a variety of advanced tools for precisely measuring the structure and chemical composition of materials at sub-nanometer scales. These images were prepared ...

Composite battery boost

(Phys.org) —New composite materials based on selenium (Se) sulfides that act as the positive electrode in a rechargeable lithium-ion (Li-ion) battery could boost the range of electric vehicles by up to five times, according ...

Detection of single photons via quantum entanglement

Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of ...

Investigating ocean currents using uranium-236 from the 1960s

Stephan Winkler, isotope researcher at the University of Vienna, has identified the bomb-pulse of uranium-236 in corals from the Caribbean Sea for the first time. 236U was distributed world-wide in the period of atmospheric ...
