Thwarting oil-pipeline corrosion by identifying a nanoscale villain
June 6, 2019 • ALBUQUERQUE, N.M. — Steel pipes rust and eventually fail. To preempt disasters, oil companies and others have created computer models to predict when replacement is needed. But if the models themselves go wrong, they can be modified only through experience, a costly problem if detection comes too late. Now, researchers...

Mirage software automates design of optical metamaterials
March 27, 2019 • ALBUQUERQUE, N.M. — New software lets users design science-fiction-like materials with the same efficiency that architects draft building plans. Sandia National Laboratories has created the first inverse-design software for optical metamaterials — meaning users start by describing the result they want, and the software fills in the steps to get...

International corrosion society elects first Sandia fellow
June 4, 2018 • ALBUQUERQUE, N.M. — A decade ago, while studying potential corrosion of containers for the proposed Yucca Mountain nuclear waste repository in Nevada, Sandia National Laboratories materials scientist David Enos designed an intricate solution to a sticky problem. Computer simulations showed the likelihood of unusually high heat and humidity deep inside...

A splash of detergent makes catalytic compounds more powerful
May 30, 2018 • ALBUQUERQUE, N.M — Researcher David Rosenberg examines images of a white powder under a powerful scanning electron microscope. Up close, the powder looks like coarse gravel, a heap of similar but irregular chunks. Then he looks at a second image — the same material produced by colleague Hongyou Fan instead...
