New Soft Matter Electrostatic Levitator makes possible world’s first neutron scattering on levitated salt solution droplets up to extreme supersaturation

John Jonghyun Lee, assistant professor of mechanical engineering, led research that demonstrated the world’s first neutron scattering on levitated salt solution droplets up to extreme supersaturation. The team used a novel instrument they designed called a Soft Matter Electrostatic Levitator (SEL), integrated into the Department of Energy’s Oak Ridge National Laboratory’s High Flux Isotope Reactor’s WAND2 facility.

“Revolutionary” multi-material for light-based 3D printing

Adarsh Krishnamurthy co-leads a new $800,000 project to identify and study single resins that can create different materials and properties – such as stiffness – when exposed to different light wavelengths.

“We want to produce two material properties with the same resin. That’s revolutionary in terms of materials for Digital Light Processing 3D printing,” said Krishnamurthy.
