Researchers create first entropy-stabilized complex oxide alloysSeptember 29, 2015

Researchers from North Carolina State University, using the Advanced Photon Source, have created the first entropy-stabilized alloy that incorporates oxides – and demonstrated conclusively that the crystalline structure of the material can be determined by disorder at the atomic scale rather than chemical bonding.

Traveling Electrons in Loosely Bound LayersSeptember 24, 2015

The metal tungsten ditelluride (WTe2) cleaves easily into atomically thin 2-dimensional layers, but its electrons conduct well in all directions, suggesting a rare case of good charge conduction across weak mechanical bonds.

Big, Deep, and Smart Data in Energy Materials Research: Atomic View on Materials Functionalities
Abstract: Structural and electronic properties of oxide surfaces control their physical functionalities and electrocatalytic activity, and they are of interest for energy generation and storage applications. In this presentation, I will discuss several examples of high-resolution studies of the electronic and electrochemical properties of oxide surfaces enabled by multidimensional scanning probe microscopies.
Team announces breakthrough observation of Mott transition in a superconductorSeptember 11, 2015

An international team of researchers announced today in Science the observation of a dynamic Mott transition in a superconductor. The discovery experimentally connects the worlds of classical and quantum mechanics and illuminates the mysterious nature of the Mott transition. It also could shed light on non-equilibrium physics, which is poorly understood but governs most of what occurs in our world. The finding may also represent a step towards more efficient electronics based on the Mott transition.

Accelerating Electrolyte Discovery by Computational Screening

With increased interest in development of advanced electrical energy storage systems, it is essential to find new electrolytes that function effectively. Computational screening techniques have been found to be an effective alternative to the trial and error of experimentation for discovery of new materials. This talk will introduce a hierarchical computational scheme to screen multiple properties of advanced electrical energy storage electrolytes using high-throughput quantum chemical calculations.

Magnetic Phase Separation for Solvent Extraction

Patent-pending simple technique where phase separation is significantly enhanced using a magnetic field from inexpensive magnets, relying on the paramagnetic nature of the extracted metal ions and without adding any extra magnetic particles into the system. The technique significantly accelerates phase disengagements and improves phase clarity.
