Fast track control accelerates switching of quantum bits
An international collaboration among physicists at the University of Chicago, Argonne National Laboratory, McGill University and the University of Konstanz recently demonstrated a new framework for faster control of a quantum bit -- the basic unit of information in yet-to-be created quantum computers -- in findings published online Nov. 28 in Nature Physics. Their experiments on a single electron in a diamond chip could create quantum devices less prone to errors when operated at high speeds.

Ceramic matrix composites take flight in LEAP jet engine
Ceramic matrix composite (CMC) materials are tough, lightweight and capable of withstanding temperatures 300-400 degrees F hotter than metal alloys can endure. A quarter-century ago, the US Department of Energy began a program, led by DOE's Oak Ridge National Laboratory, to support US development of CMC materials. This year, LEAP, a new aircraft engine, became the first widely deployed CMC-containing product. CFM International, a 50/50 joint venture of Safran and GE, manufactures LEAP.

For critical marine low clouds, a research and observation plan
Marine low clouds hover in the lowest couple of kilometers above the world's oceans. They produce little but drizzle, and could never match their deeper mid-continent cousin clouds for dramatic weather and severe storms. But marine low clouds are vastly important to the world's climate and energy balance.

Scientists bear witness to birth of an ice cloud

Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the very first steps of cloud formation. The team took time-lapse movies of the first few seconds when a particle attracts water vapor, forming ice crystals that become the core of icy cirrus clouds - the high, wispy clouds that act much like a blanket for our planet.

Peering into batteries: X-rays reveal lithium-ion's mysteries
Scientists are using x-rays from the national laboratories' advanced light sources to study the movement and structure of lithium-ion batteries in real time, as the batteries function. This technique led to the development of the cathode used in the Chevrolet Volt and is now being used to further improve our understanding of batteries.

New technique reveals powerful, 'patchy' approach to nanoparticle synthesis
Patches of chain-like molecules placed across nanoscale particles can radically transform the optical, electronic, and magnetic properties of particle-based materials. Now, scientists have used cutting-edge electron tomography techniques -- a process of 3-D reconstructive imaging -- to pinpoint the structure and composition of the polymer nano-patches.

Sandia experts, students explore mechanical challenges at summer institute
Nearly 40 students ranging from local high school youths to international postdoctoral fellows gathered this summer at Sandia National Laboratories' Nonlinear Mechanics and Dynamics (NOMAD) Summer Research Institute to study two steel bars bolted together. This deceptively simple system behaves in odd -- nonlinear -- ways, which has important implications for bridges, cars, even airplanes.
