Barely wider than a strand of human DNA, magnetic nanoparticles—such as those made from iron and platinum atoms—are promising materials for next-generation recording and storage devices like hard drives. Building these devices from nanoparticles should increase storage capaci...
Neutron analysis at the Department of Energy’s Oak Ridge National Laboratory is helping researchers better understand a key enzyme found in a bacterium known to cause stomach cancer.
Understanding the details of this enzyme, and thus the Helicobacter pylori bacteria’s metabolis...
Snow falls in winter and melts in spring, but what drives the phase change in between?
Ever since Italian physicist Alessandro Volta invented the first battery out of a stack of copper and zinc disks separated by moistened cardboard, scientists have been searching for better battery materials.
Supercomputers like Oak Ridge National Laboratory’s Titan are advancing science at a frenetic pace and helping researchers make sense of data that could have easily been missed, says Ramakrishnan “Ramki” Kannan. Kannan, a computer scientist who came to ORNL in March 2016 after ...
When matter changes from solids to liquids to vapors, the changes are called phase transitions. Among the most interesting types are more exotic changes—quantum phase transitions—where the strange properties of quantum mechanics can bring about extraordinary changes in curious way...
