Scientists Create Continuously Emitting Microlasers With Nanoparticle-Coated Beads

Image - At left, a tiny bead struck by a laser (at the yellowish spot shown at the top of the image) produces optical modes that circulate around the interior of the bead (pinkish ring). At right, a simulation of how the optical field inside a 5-micron (5 millionths of a meter) bead is distributed. (Credit: Angel Fernandez-Bravo/Berkeley Lab, Kaiyuan Yao)

From Moon Rocks to Space Dust: Berkeley Lab's Extraterrestrial Research

Photo - A blue crystal recovered from a meteorite that fell near Morocco in 1998. The scale bar represents 200 microns (millionths of a meter). Such crystals, which have been studied at Berkeley Lab, have been found to contain liquid water and complex organic compounds. (Credit: Queenie Chan/The Open University, U.K.)

Experiments at Berkeley Lab Help Trace Interstellar Dust Back to Solar System’s Formation

Image - An elemental map of tiny glassy grains (blue with green specks) inside a cometary-type interplanetary dust particle. Carbonaceous material (red) holds these objects together. This image was collected from a thin section of the particle using a scanning transmission electron microscope.

Non-Crystal Clarity: Scientists Find Ordered Magnetic Patterns in Disordered Magnetic Material

Image - In these rows of sequenced images, produced using X-ray-based techniques, the first column shows the demagnetized state of a multilayer material containing gadolinium and cobalt; the second column shows the residual magnetism in the same samples after an external, positive magnetic field was applied and then removed; and the last column shows the samples when a negative magnetic field is applied. The white arrows in the third row of images indicate gadolinium-rich regions in the material. (Credit: Berkeley Lab)

Graphene Layered With Magnetic Materials Could Drive Ultrathin Spintronics

Photo - Andreas Schmid, left, and Gong Chen are pictured here with the spin-polarized low-energy electron microscopy (SPLEEM) instrument at Berkeley Lab that was integral to magnetic measurements of ultrathin samples that included graphene and magnetic materials.

Nanoparticle Breakthrough Could Capture Unseen Light for Solar Energy Conversion

Image - An erbium atom (red) in a nanocrystal emits visible, green light via a process known as upconversion that could lead to the development of improved solar cells that capture some previously missed solar energy. Scientists discovered that coating the particles with dyes (blue and purple molecules at right) can greatly enhance this light-converting property. (Credit: Berkeley Lab)
