Scientists must often ask themselves, compared to what? How do the results we generate in the laboratory compare with those obtained by others? How do our theoretical calculations compare with experimental data? Answering such questions is especially crucial for researchers and developers of lithium-ion batteries. Invented four decades ago, lithium-ion batteries now power most portable […]
Scientists Use Magnetic Defects to Achieve Electromagnetic Wave Breakthrough
Surfers spend much of their time watching long waves come onto the shoreline as they attempt to catch one right as it begins to curve and break. In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the […]
Mirror, Mirror
The world on the other side of Alice in Wonderland’s looking-glass is not what it seems, but the mirror-like physics of the superconductor-insulator transition operates exactly as expected. Scientists know this to be true following the observation of a remarkable phenomenon, the existence of which was predicted three decades ago but that had eluded experimental […]
Scientists Have A New Way To Gauge The Growth Of Nanowires
In a new study, researchers from the U.S. Department of Energy’s (DOE) Argonne and Brookhaven National Laboratories observed the formation of two kinds of defects in individual nanowires, which are smaller in diameter than a human hair. These nanowires, made of indium gallium arsenide, could be useful for a wide range of applications in a […]
A Marriage Of Light-Manipulation Technologies
Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving cars and trucks. In the collaborative effort between the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Harvard University, researchers successfully crafted a metasurface-based lens atop […]
Argonne To Install Comanche System To Explore ARM Technology For HPC
The U.S. Department of Energy’s (DOE) Argonne National Laboratory is collaborating with Hewlett Packard Enterprise (HPE) to provide system software expertise and a development ecosystem for a future high-performance computing (HPC) system based on 64-bit ARM processors. ARM is a RISC-based processor architecture that has dominated the mobile computing space for years. That dominance is […]
X-Rays Tuned with Tiny Mirrors
The secret of X-ray science – like so much else – is in the timing. Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory have created a new way of manipulating high-intensity X-rays, which will allow researchers to select extremely brief but precise X-ray bursts for their experiments. The new technology, developed by […]
