Rice scientists pull off quantum coup
Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place.
Metal Alloys to Support to Nuclear Fusion Energy
Tungsten heavy alloys show promise for nuclear fusion energy development, according to new research conducted at PNNL.
Additively Manufacturing a Better Steel: The Key Could be in Synchrotron X-ray Techniques
A study led by Stony Brook University sheds light on the connection between the corrosion behavior and underlying materials structure in laser additively manufactured 316L stainless steel – a corrosion resistant metal. The findings may help to map pathways for engineering an even better printed alloy.
Tiny but mighty precipitates toughen a structural alloy
Scientists at Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates into its matrix and tuning their size and spacing.
Islands without structure inside metal alloys could lead to tougher materials
An international team of researchers produced islands of amorphous, non-crystalline material inside a class of new metal alloys known as high-entropy alloys. This discovery opens the door to applications in everything from landing gears, to pipelines, to automobiles. The new materials could make these lighter, safer, and more energy efficient.
2D Electronics Get an Atomic Tuneup
Scientists at Berkeley Lab have demonstrated a new technique that could improve the performance of atomically thin semiconductors for next-generation electronics such as optoelectronics, thermoelectrics, and sensors.
Quantum Effect Triggers Unusual Material Expansion
New research conducted in part at Brookhaven Laboratory may bring a whole new class of chemical elements into a materials science balancing act for designing alloys for aviation and other applications.
