Newswise: Machine learning analyses help unlock secrets of stable ‘supercrystal’

Machine learning analyses help unlock secrets of stable ‘supercrystal’

Oak Ridge National Laboratory

By blasting a frustrated mixture of materials with quick pulses of laser light, researchers transformed a superlattice into a supercrystal, a rare, repeating, three-dimensional structural much larger than an ordinary crystal. Using machine learning techniques, they studied the underlying structure of this sample at the nanoscale level before and after applying the laser pulse treatment.

Obtaining order in the “frustrated” landscape of disordered magnetism

Oak Ridge National Laboratory

Researchers from Aarhus University, Denmark, are pioneering a novel technique to solve highly elaborate magnetic structures using neutrons at the Spallation Neutron Source. Their aim is to develop the technique to establish a baseline approach that can be adapted to a broad class of magnetic materials with different structures.

Story tips from the Department of Energy's Oak Ridge National Laboratory, November 2019

Oak Ridge National Laboratory

ORNL and NREL took demonstrated a miniaturized gyroscope. ORNL created and tested new wireless charging designs. If humankind reaches Mars this century, an ORNL-developed experiment testing advanced materials for spacecraft may play a key role. ORNL and Georgia Tech found that critical interactions between microbes and peat moss break down under warming temperatures. ORNL and industry demonstrated that an additively manufactured hot stamping die can withstand up to 25,000 usage cycles.

Gordon Bell Finalist Team Tackles Transistors with New Programming Paradigm

Oak Ridge National Laboratory

A team simulated a 10,000-atom 2D transistor slice on the Summit supercomputer and mapped where heat is produced in a single transistor. Using a new data-centric version of the OMEN nanodevice simulator, the team sustained the code at 85.45 petaflops and earned a Gordon Bell Prize finalist nomination.
