Hollow glass nano-cylinders were fabricated using EBL. Gold was evaporated to infill the structures. To polish the surface and make the cylinders optically accessible the surface was polished using the FIB under very grazing angles. The material acts as a negative index metamaterial for visible wavelenghts or the cylinders can be used as plasmonic material to enhance optical trapping forces several orders of magnitude.

Sandia National Laboratories researcher Guangping Xu employs a digital optical microscope to examine the unusually hard coatings inspired by seashells that his lab has produced. The aim is better, cheaper protection of instruments and drivers in danger of fast-moving debris flung by Sandia’s Z machine when it fires. The coatings offer many other possibilities as well.

Physicist Chad McCoy at Sandia National Laboratories’ Z machine loads sample coatings into holders. The coatings are made up of very thin layers of confectioners’ sugar from the grocers, burnt to a state called carbon black, interspersed between only slightly thicker layers of silica, which is the most common material on Earth, and baked. When Z fires, researchers will observe how well particular coatings protect objects stacked behind them.

This image is the first of its kind taken on an FEI/Thermo Fisher microscope. The electron column was configured via iFast to rock the beam about a single point instead of raster across the sample surface. Contrast comes from subsequent alignment and misalignment of the primary beam with the silicon atomic lattice. The resulting pattern can be indexed to give the exact crystal orientation in the interaction area.

Intense optical pulses of laser light can manipulate electron motion, or "spin" and switch the magnetization in metallic films, yet the mechanism that causes electrons' spins to reverse their orientation has remained a mystery. New results from the LCLS reveal the importance of the nanoscale structure of the sample itself in these optically excited switching processes. As the laser light hits the sample, iron spin currents are generated that transfer their angular momentum to gadolinium spins within nanoscale regions of the sample. The localized transfer of angular momentum leads to an increase in magnetic order and a reversal in magnetism in specific regions, even as the bulk of the sample becomes disordered.

As part of that mission, the group utilizes synchrotron characterization techniques such as diffraction, spectroscopy, and imaging and is developing sample chambers for the in situ study of materials at the National Synchrotron Light Source (NSLS). Group members Avishai Ofan and Simerjeet Gill are shown at beamline X14A at the NSLS.
In 2018, Sandia fellow and University of New Mexico regents’ professor Jeff Brinker was elected a fellow of the American Academy of Arts and Sciences, the oldest learned society and independent policy research center in the United States. Brinker has made pioneering contributions to the processing and characterization of porous and composite nanostructured materials. He was one of the first to champion the need for multidisciplinary materials research.

Sandia National Laboratories researcher Israel Owens holds the optical sensor used to house the crystal that proved central to his team’s successful attempts to measure very high voltages. The two red spots on each side of the crystal are due to laser light reflecting off the side mirrors used to direct light through the middle of the crystal. The actual experiments used green laser light.

Carbon fiber or carbon fibre (alternatively CF, graphite fiber or graphite fibre) is a material consisting of fibers about 5–10 micrometres in diameter and composed mostly of carbon atoms.
To produce carbon fiber, the carbon atoms are bonded together in crystals that are more or less aligned parallel to the long axis of the fiber as the crystal alignment gives the fiber high strength-to-volume ratio (making it strong for its size). Several thousand carbon fibers are bundled together to form a tow, which may be used by itself or woven into a fabric.
