Scientists guide gold nanoparticles to form 'diamond' superlattices

UPTON, NY-Using bundled strands of DNA to build Tinkertoy-like tetrahedral cages, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have devised a way to trap and arrange nanoparticles in a way that mimics the crystalline structure of diamond. read more

Coupling 2 'tabletop' laser-plasma accelerators: A step toward ultrapowerful accelerators

Laser-plasma accelerators (LPAs) got the nickname "tabletop" because, as shown by the unique BELLA accelerator at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), they can boost electron beams to multibillion electron-volt energies (GeVs) in a few centimeters--a distance thousands of times shorter than conventional accelerators. read more

Gigantic Wind Turbine With 650 Foot Blades Will Channel the Power of Hurricanes  

2 weeks agoTechnology / Gadgets : Gizmodo

The DOE wants to step up its wind energy game in a big way. And I mean big. Sandia National Laboratories has been tasked with the challenge of designing an offshore wind turbine that can spin out 50 megawatts of carbon-free juice—using 650 foot blades that harness the fiercest winds on Earth.

Meet The Carbon Dioxide Battery

Carbon dioxide goes in. Heat comes out. That is the basic idea behind the Earth Battery, a novel, grid-scale energy storage concept from Thomas Buscheck and a team of researchers at Lawrence Livermore National Laboratory. Carbon dioxide captured from factories or power plants would be pressurized until it enters a ‘supercritical’ [...]

Ames Laboratory DNP-NMR Spectrometer Offers Higher Speed, More Precision

In just a little over a year of operation, the U.S. Department of Energy Ames Laboratory's dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) spectrometer has successfully characterized materials at the atomic scale level with more speed and precision than ever possible before.
