X-ray imaging and computer modeling help map electric properties of nanomaterials

Argonne researchers have developed a new approach for studying piezoelectric materials using ultrafast 3-D X-ray imaging and computer modeling. Their integrated approach, reported in Nano Letters, can help us better understand material behavior and engineer more powerful and energy-efficient technologies.

Electrons "puddle" under high magnetic fields, study reveals

In a new study, researchers used extremely high magnetic fields — equivalent to those found in the center of neutron stars — to alter electronic behavior. By observing the change in the behavior of these electrons, scientists may be able to gain an enriched understanding of material behavior.

Machine learning enables predictive modeling of 2-D materials

In a study published in The Journal of Physical Chemistry Letters, a team of researchers led by Argonne computational scientist Subramanian Sankaranarayanan described their use of machine learning tools to create the first atomic-level model that accurately predicts the thermal properties of stanene, a 2-D material made up of a one-atom-thick sheet of tin.

Building project managers and scientific leads confer at the site of a new clean room under construction at Argonne National Laboratory. When completed, the lab will enable scientists and engineers to build extremely sensitive detectors — such as those capable of detecting light from the early days of the universe.

Building a room clean enough to make sensors to find light from the birth of the universe

Work is underway at Argonne on an expansion of its “clean room.” The new lab will be specially suited for building parts for ultra-sensitive detectors — such as those to carry out improved X-ray research, or for the South Pole Telescope to search for light from the early days of the universe.

No one has yet imaged an entire brain down to the level of individual cells; but Bobby Kasthuri has a plan to do just that using intensive computing and imaging resources at Argonne. Above is a simulation showing an unusual configuration of a neuron: one axon (blue) connected to multiple points on a dendrite (green). The total image is smaller than the diameter of a single human hair. (Click to view larger.)
Adventures of the first neuroscientist at Argonne

Bobby Kasthuri wants to map the human brain. Unlike most brain researchers, he wants a literal map: a 3D picture of every single neuron inside a brain. All 100 billion of them — or maybe 80 billion. Or maybe 120 billion?
