Nanotemplates for nanostructures

DOE/Sandia National Laboratories

Coffee beans spilled upon a table form no pattern—they're a mess—their distribution dictated by the laws of chance. The same was generally believed true of atoms deposited upon a substrate. The first vision of a peaceable kingdom in which deposited atoms form orderly, controllable 2-D nanopatterns has been observed by researchers at the Sandia National Laboratories.

First controllable 2D nanopatterns imaged by Sandia researchers — Nanotemplates for nanostructures

Z-Beamlet image shows Z evenly compresses pellet

DOE/Sandia National Laboratories
Peer-Reviewed Publication

In its first try as a Sandia National Laboratories diagnostic tool, the third-biggest laser on earth, Z-Beamlet, confirmed that Sandia’s Z machine — the most powerful laboratory producer of X-rays in the world —spherically compressed a simulated fusion pellet during a firing, or “shot,” of the giant accelerator

Sandia creates mechanized microfluidic device — Pac-Man-like microstructure interacts with red blood cells

DOE/Sandia National Laboratories
Peer-Reviewed Publication

Silicon microteeth that open and close like jaws have been developed at Sandia National Laboratories. Microjaws fit in a microchannel about one-third the width of a human hair. When the jaws close, they trap a red blood cell. The jaws deform captured cells, and then, in less than the blink of an eye let the little things loose. The blood cells travel on, regain their former shape and appear unharmed.

Lab researcher's team shines in protein folding predictions

DOE/Los Alamos National Laboratory

The protein folding puzzle – determining the3--D structure of a protein given the sequence of its amino acids – is one of the major unsolved problems in molecular biology. A Los Alamos National Laboratory scientist along with a colleague and his students were recently recognized as the most successful team in an annual worldwide assessment of progress in protein structure prediction.

Researchers find human's earliest ancestor yet

DOE/Los Alamos National Laboratory

An international team of researchers has announced the discovery of fossil bones and teeth belonging to the earliest human ancestors yet discovered – a hominid who lived in what is now Ethiopia between 5.2 and 5.8 million years ago.

Lab builds world's first neptunium sphere

DOE/Los Alamos National Laboratory

For the first time ever, a cross-section of nuclear materials scientists and technicians at the Chemistry and Metallurgy Research (CMR) facility has fashioned an eight- kilogram tungsten-and nickel-clad sphere of neptunium. The actinide metal sphere will be used in criticality safety and nuclear non-proliferation experiments at Technical Area 18, the critical experiments facility.

The magnetic universe

DOE/Los Alamos National Laboratory

Researchers in Applied Physics and Theory Divisions have recently compiled a sample of nearly 100 giant radio galaxies powered by black holes.

Riding the d-wave

DOE/Los Alamos National Laboratory

A paper appearing in a recent issue of the journal Nature has helped validate a theory on the enigmatic nature of superconducting materials that was first advanced by Los Alamos National Laboratory researcher Alexander Balatsky and his colleagues five years ago. The confirmation of the theory is another step in solving the enigma of superconductivity.

Sandia to release first risk-based approach to building management software for use by GSA— Tool against terrorism and other disasters

DOE/Sandia National Laboratories
Peer-Reviewed Publication

RAMPART, software developed by Sandia National Laboratories that is the first risk-based approach to building management, may soon help the General Services Administration (GSA) assess the risks of terrorism, natural disasters and crime to the nearly 8,000 federal buildings it manages nationwide.
