An Oak Ridge National Laboratory-led team discovered a function of certain microbes that produces a new derivative of vitamin B12, which is crucial to a cell’s ability to perform life-sustaining metabolic activities. Their findings could ultimately open avenues for novel environmental and water clean-up strategies.

Geospatial scientists at Oak Ridge National Laboratory have developed a novel method to quickly gather building structure datasets that support emergency response teams assessing properties damaged by Hurricanes Harvey and Irma. By coupling deep learning with high-performance comp...

A novel, two-dimensional material “puckers” because its structure is composed of atoms that tile in the famous Cairo pentagonal pattern, opening exciting new opportunities for nanoelectronics. Credit: Christopher Rouleau and Kai Xiao/Oak Ridge National La
A semiconducting material with a puckered pentagonal atomic structure, characterized by Oak Ridge National Laboratory, could rival graphene and black phosphorus as a viable option for nanoscale electronics. The ORNL-led team studied a novel two-dimensional, or atomic-thin, layered...
Oak Ridge National Laboratory’s Bo Shen works with a prototype window air conditioning unit that cools using propane, which lowers costs, increases efficiency and benefits the environment.

Cooling homes and small office spaces could become less costly and more efficient with new early stage technology developed by Oak Ridge National Laboratory. Researchers designed a window air conditioning unit that uses propane as the refrigerant, cooling the air with 17 percent h...
