Researchers Reveal Individual Fluorescent Color Centers in Diamonds using STED Microscopy

A research team at the Max Planck Institute for Biophysical Chemistry in Göttingen has now probed these color centers inside the crystal with unprecedented resolution using an optical microscope. Using STED microscopy, the scientists identified even densely packed color centers and determined their position inside the crystal with a precision better than 0.15 nanometers, corresponding to the dimension of an atom.

We Energies Looks to Control Costs Using LED Streetlights with Advanced Lighting Controls

BetaLED is testing two leading forms of lighting control systems with its LEDway streetlights. Eleven LEDway streetlights installed along 92nd Street in Sturtevant, Wis., were recently outfitted with either a power line communication system or wireless radio frequency (RF) system as part of a side-by-side demonstration of lighting control technologies available for LED streetlights.

Precisely Measuring One-Neutron Halo using Lasers

Atomic nuclei are normally compact structures defined by a sharp border. About twenty-five years ago, it was discovered at the University of California in Berkeley that there are exceptions to this picture: Certain exotic atomic nuclei contain particles that shear off from the central core and create a cloud, which surrounds the central core like a 'heiligenschein' or halo.

Hundred Metre Virtual Telescope Captures Unique Detailed Colour Image

"This is one of the first images made using near-infrared interferometry," says lead author Jean-Baptiste Le Bouquin. Interferometry is a technique that combines the light from several telescopes, resulting in a vision as sharp as that of a giant telescope with a diameter equal to the largest separation between the telescopes used.
