Shape-shifting plastic
Researchers from Oak Ridge National Laboratory, Washington State University and the University of Idaho have developed a process to make a thermoset that can be reshaped and reused. The new plastic is a shape-memory polymer, so named because the material can 'remember' its original shape and return to it after being deformed with heat or other forces.

SLAC gears up for dark matter hunt with LUX-ZEPLIN
The US Department of Energy (DOE) recently signed off on the conceptual design of the proposed LUX-ZEPLIN (LZ) experiment and gave the green light for the procurement of some of its components. DOE's SLAC National Accelerator Laboratory, a key member of the LZ collaboration, is setting up a test stand for the detector prototype and a facility to purify liquid xenon, which will be the detector's 'eye' for dark matter.

ORNL group leads calorimeter upgrade for Large Hadron Collider experiment
Run-2 for the Large Hadron Collider -- the world's largest and most powerful particle collider -- began April 5 at CERN. In preparation, Thomas M. Cormier, who leads the LHC Heavy Ion group at Oak Ridge National Laboratory, led an upgrade of the electromagnetic calorimeter used for LHC's experiment called ALICE (for A Large Ion Collider Experiment). This detector measures the energies of high-energy electrons and gamma rays emitted from the quark-gluon plasma.

Metamaterials shine bright as new terahertz source
Terahertz waves are used in information, communication, processing, and data storage technologies, yet few terahertz sources are available due to the limitations of natural materials. Scientists discovered an efficient terahertz emission from two-dimensional arrays of gold split-ring resonator metamaterials, which allow design and use of light-matter interactions at a fundamental level. This discovery opens new ways to use such materials.

Highly conductive germanium nanowires made by a simple, 1-step process
For the first time, germanium nanowires that can be used as high-capacity anode material for lithium-ion batteries were deposited on an indium tin oxide substrate using electrodeposition, a simple, one-step process.

Intertwining of superconductivity and magnetism
Experiments reveal nearly static, spatially modulated magnetism in a copper-oxide superconductor. Because static magnetism and superconductivity prefer not to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory. This study will assist in developing a predictive theory for high-temperature superconductivity that can assist in the design and discovery of improved superconductors.
