OLCF Researcher to Work with Clean Combustion Center at Saudi University
— If you were to do an internet search for what causes engine knock, you’d receive a number of answers.

Predicting performance
— When Orlando Rios first started analyzing samples of carbon fibers made from a woody plant polymer known as lignin, he noticed something unusual. The material’s microstructure -- a mixture of perfectly spherical nanoscale crystallites distributed within a fibrous matrix -- looked almost too good to be true.

Best of two worlds
— Traditional science and business are coming together in a way that Bredesen Center for Interdisciplinary Research and Graduate Education student Beth Papanek believes will help graduates advance their careers.

Imaging Fuel Injectors with Neutrons
— Blowing bubbles may be fun for kids, but for engineers, bubbles can disrupt fluid flow and damage metal.

A Metallic Alloy That is Tough and Ductile at Cryogenic Temperatures
— A new concept in metallic alloy design – called “high‐entropy alloys” - has yielded a multiple-element material that not only tests out as one of the toughest on record, but, unlike most materials, the toughness as well as the strength and ductility of this alloy actually improves at cryogenic temperatures.

CO2 please
— Keeping food fresh is no easy feat. Trials of transporting ice over long distances and the hazards of systems that rely on toxic gases riddle the pages of refrigeration history. And although cooling science has come a long way in the past two centuries, modern refrigeration has an environmental cost that poses new challenges.

Materials Scientists Play Atomic ‘Jenga’ and Make a Surprising Discovery
— Researchers at the Department of Energy’s Oak Ridge National Laboratory got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges.

Neutron science workshops seek to define field’s grand challenges
— OAK RIDGE, Tenn., August 27, 2014 — The Department of Energy’s Oak Ridge National Laboratory concluded a series of workshops this month that engaged scientists from around the country to identify grand scientific challenges and how they might be addressed through application of neutron science.

Scientists learn to control reactions with the shape of a rare-earth catalyst
— Scientists at the Department of Energy’s Oak Ridge National Laboratory have discovered they can control chemical reactions in a new way by creating different shapes of cerium oxide, a rare-earth-based catalyst. Their finding holds potential for refining fuels, decreasing vehicle emissions, producing commodity chemicals and advancing fuel cells and chemical sensors.

Health data + ORNL computing = Smarter health care
— As the United States strives to improve health care, the Department of Energy’s Oak Ridge National Laboratory is using computing to delve deeper into big health data and is proposing innovative solutions to grand challenges in the country’s health care system.
