New exascale earth modeling system for energy

New exascale earth modeling system for energy

April 24, 2018 – A new earth modeling system will use advanced computers and have weather scale resolution to simulate aspects of Earth’s variability and anticipate decadal changes that will critically impact the United States’ energy sector. The Energy Exascale Earth System Model, or E3SM, release will include model code and documentation, as well as output from an initial set of benchmark simulations useful to the broader scientific community engaged in a myriad of energy research endeavors.

Machine speak: Left to their own devices, computers can figure it out

April 23, 2018 - Using novel machine learning techniques, a research team from the Department of Energy’s Oak Ridge National Laboratory is teaching electronic devices how to speak for themselves.
Dane Morgan and Ryan Jacobs opened up new windows into how strain alters the superconducting properties of a class of materials called Ruddelsden-Popper oxides.

Strained materials make cooler superconductors

April 23, 2018 – University of Wisconsin-Madison engineers have added a new dimension to our understanding of why straining a particular group of materials, called Ruddlesden-Popper oxides, tampers with their superconducting properties. The findings, published in the journal Nature Communications, could help pave the way toward new advanced electronics.
Neutron interactions revealed the orthorhombic structure of the hybrid perovskite stabilized by the strong hydrogen bonds between the nitrogen substituent of the methylammonium cations and the bromides on the corner-linked PbBr6 octahedra.

Neutrons provide insights into increased performance for hybrid perovskite solar cells

OAK RIDGE, Tenn., April 23, 2018 – Neutron scattering has revealed, in real time, the fundamental mechanisms behind the conversion of sunlight into energy in hybrid perovskite materials. A better understanding of this behavior will enable manufacturers to design solar cells with increased efficiency.

Bundling big science tools to shed light on flexible proteins

April 18, 2018—Nearly a dozen scientists across Oak Ridge National Laboratory are teaming with medical researchers and leveraging ORNL’s biggest science tools to solve a modern-day biology grand challenge: unlocking the secrets of disordered proteins. These flexible molecules are believed to constitute as much as half of the proteins in the human body yet are poorly understood because we have not found a way to adequately study their properties.
