Two-dimensional MXene materials get their close-up
Researchers have long sought electrically conductive materials for economical energy-storage devices. Two-dimensional (2D) ceramics called MXenes are contenders. ORNL scientists using state-of-the-art scanning transmission electron microscopy provided the first direct evidence of the atomic-defect configurations in a titanium-carbide MXene synthesized at Drexel University. Published in ACS Nano, a journal of the American Chemical Society, the study coupled atomic-scale characterization and electrical property measurements with theory-based simulation.

Nidia Gallego: Carbon scientist is as versatile as the element she studies
At the Department of Energy's Oak Ridge National Laboratory, Nidia Gallego develops carbon materials for energy technologies and space exploration. She investigates the physical and chemical properties of carbon in diverse forms -- including fiber, composites and foam. 'Carbon is a single element that can be many things,' Gallego said. 'It can be hard like diamond, soft like graphite or amorphous like activated carbon. Its material properties depend on how carbon atoms bond with each other.'

High-precision calculations on supercomputers help reveal the physics of the universe

Argonne researchers have developed a new theoretical approach, ideally suited for high-performance computing systems, capable of making predictive calculations about particle interactions that conform almost exactly to experimental data. This new approach could give scientists a valuable tool for describing new physics and particles beyond those currently identified.

Cracking the Mystery of Perfect Efficiency: Investigating Superconductors
A whole new area of research emerged from the discovery of superconductivity in 1911. Since then, scientists have learned why some materials superconduct near absolute zero and have discovered 'high-temperature' superconductors. Now, researchers supported by the Department of Energy's Office of Science are working to identify a common characteristic of high-temperature superconductors in hopes of one day developing one that works at room temperature.

New droplet-on-tape method assists biochemical research at X-ray lasers
Scientists at the Department of Energy's Lawrence Berkeley National Laboratory, SLAC National Accelerator Laboratory, Brookhaven National Laboratory, and other institutes designed a new assembly-line system that rapidly replaces exposed biological samples by moving droplets along a miniature conveyor belt, timed to coincide with the arrival of the X-ray pulses. The droplet-on-tape system now allows the team to study the biochemical reactions in real-time from microseconds to seconds, revealing the stages of these complex reactions.

Sandia using kinetics, not temperature, to make ceramic coatings
Sandia National Laboratories is working on a way to lay down ceramic coatings kinetically and at room temperatures. Coating at room temperature makes microelectronics design and fabrication more flexible and could someday lead to better, less expensive microelectronics components that underpin modern technology.
