Flying Quieter and Cleaner

From a nondescript industrial building in the small town of Crossville, Tennessee, the team of engineers at Whisper Aero is planning a revolution in aviation technology. Previously home to a publisher of magazines — including, coincidentally, Trade-A-Plane, an airplane sales publication started in 1937 — the long-empty property’s cavernous spaces…

Exascale’s New Frontier: ExaWind

PI: Michael Sprague, National Renewable Energy Laboratory In 2016, the Department of Energy’s (DOE’s) Exascale Computing Project (ECP) set out to prepare advanced software for the arrival of exascale-class supercomputers capable of 1 quintillion or more calculations per second. That meant rethinking, reinventing and optimizing dozens of scientific applications and…

Frontier Simulations Could Help Build a Better Diamond

The world’s fastest supercomputer helped researchers simulate synthesizing a material harder and tougher than diamond — or any other substance on Earth. The study used Frontier, the HPE Cray EX supercomputing system at the Department of Energy’s Oak Ridge National Laboratory, to predict the likeliest strategy to synthesize such a…

New Clues to Improving Fusion Confinement

Nuclear fusion — when two nuclei combine to form a new nucleus, thereby releasing energy — may be the clean, reliable, limitless power source of the future. But first, scientists must learn how to control its production. Building on decades of prior research, scientists have developed sophisticated techniques to improve…

Untangling the Entangled

Researchers used quantum simulations to obtain new insights into the nature of neutrinos — the mysterious subatomic particles that abound throughout the universe — and their role in the deaths of massive stars. The study relied on support from the Quantum Computing User Program, or QCUP, and the Quantum Science Center, a national Quantum Information…

Something in the Water Does Not Compute

Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…

Summit Helps Forge Stronger Flights

Titanium alloys serve as cornerstone materials for the aerospace industry — stronger and lighter than steel, resistant to rust and corrosion and resilient past the melting points of most other metals. Companies such as RTX, formerly Raytheon Technologies, rely on these sturdy alloys to build such vital machinery as jet-engine turbine…
