A depiction of magnetic charge ice. Nanoscale magnets are arranged in a two-dimensional lattice. Each nanomagnet produces a pair of magnetic charges, one positive (the red ball on the north pole) and one negative (the blue ball on the south pole). The magnetic flux lines (white) point from positive charges to negative charges. (Image credit: Yong-Lei Wang/Zhili Xiao)
Scientists create 'magnetic charge ice'

A team of scientists working at Argonne National Laboratory, led by Northern Illinois University physicist and Argonne materials scientist Zhili Xiao, has created a new material called “rewritable magnetic charge ice” that permits an unprecedented degree of control over local magnetic fields and could pave the way for new computing technologies.

New device steps toward isolating single electrons for quantum computing

If biochemists had access to a quantum computer, they could perfectly simulate the properties of new molecules to develop novel drugs in ways that would take the fastest existing computers decades.

Gone with the wind: Argonne coating shows surprising potential to improve reliability in wind power

A group of researchers from Argonne National Laboratory and the University of Akron discovered that a particular form of carbon coating not necessarily designed for wind turbines may indeed prove a boon to the wind industry.

Stable "superoxide" opens the door to a new class of batteries

Argonne scientists, working with American and Korean collaborators, produced stable crystallized lithium superoxide during battery discharging. Unlike lithium peroxide, this superoxide can easily dissociate into lithium and oxygen, leading to high efficiency and good cycle life in lithium-air batteries.

This image shows an atomic-resolution topographic rendering of the borophene surface, taken in the scanning tunneling microscope. The borophene sheet forms large buckled wrinkles, as seen in the center, in response to the underlying silver crystal. These atomic scale wrinkles may serve to steer the flow of electrons and could lead to other surprising properties. (Click to view larger.)
Scientists create atomically thin metallic boron

A team of scientists at Argonne, Northwestern University and Stony Brook University has, for the first time, created a two-dimensional sheet of boron – a material known as borophene.

Occidental College researcher Janet Scheel will use Argonne Leadership Computing Facility resources for her 2016 INCITE project “Convective Turbulence in Liquid Gallium and Sodium.” This image displays streamlines of the two-dimensional skin friction field that was obtained right at the heated bottom plate of a cylindrical cell for turbulent Rayleigh-Bénard convection in liquid mercury at a Rayleigh number of a hundred million. The field displays the complex dynamics of the velocity field. (Image credit: Joerg Schumacher, Technische Universitaet Ilmenau)
INCITE grants awarded to 56 computational research projects

The U.S. Department of Energy has announced 56 projects aimed at accelerating discovery and innovation to address some of the world’s most challenging scientific questions. The projects will share 5.8 billion core hours on America’s two most powerful supercomputers dedicated to open science.

A team of researchers from Argonne’s Materials Science Division and Northern Illinois University, working with researchers at Argonne’s Center for Nanoscale Materials, report two new findings on tungsten ditelluride: (1) WTe2 is electronically three-dimensional with a mass anisotropy as low as 2, and (2) the mass anisotropy varies with temperature and follows the magnetoresistance behavior of the Fermi liquid state. The results not only provide a general scaling approach for the anisotropic magnetoresistance but also are crucial for correctly understanding the electronic properties of WTe2, including the origin of the remarkable “turn-on” behavior in the resistance versus temperature curve, which has been widely observed in many materials and assumed to be a metal-insulator transition.

Scientists gain insight into origin of tungsten ditelluride's magnetoresistance

Two new significant findings may move scientists closer to understanding the origins of tungsten ditelluride's extremely large magnetoresistance, a key characteristic in modern electronic devices such as magnetic hard drives and sensors.

An international team of scientists has discovered how to measure the resistance of a nanomembrane to both bending and stretching by rolling it into a tube and performing a single experiment to measure the tube's bending resistance along its length. Previous methods required two experiments: one to measure a nanomembrane's bending resistance and another to measure its stretching resistance. The discovery is expected to aid researchers working to make three-dimensional objects and devices from two-dimensional membranes only one nanoparticle thick. The transmission electron micrograph on the right was obtained at Argonne’s Center for Nanoscale Materials.  (Click for larger view.)
