Understanding heat flows is focus of DOE Early Career Award winner Delaire
— Olivier Delaire, a scientist at the Department of Energy’s Oak Ridge National Laboratory, has won a prestigious Early Career Award from DOE’s Office of Science to study how heat propagates, or moves, through matter at an atomic level.

How to create nanowires only three atoms wide with an electron beam
— Junhao Lin, a Vanderbilt University Ph.D. student and visiting scientist at Oak Ridge National Laboratory (ORNL), has found a way to use a finely focused beam of electrons to create some of the smallest wires ever made. The flexible metallic wires are only three atoms wide: One thousandth the width of the microscopic wires used to connect the transistors in today’s integrated circuits.

‘Sweet spot’ for salty water
— Computational modeling has given materials researchers new insight into the properties of a membrane that purifies saltwater into potable water. The resulting technology could help speed up inefficient desalination processes in use today.
