Yonghwa Yi and Prof. Lee successfully measured the creep properties of niobium using the electrostatic levitator equipped with an electromagnetic rotor (EMR) at NASA MSFC. Using the EMR reduced the test time by a factor of seven, yielding a comparable result. 

Lee group successfully integrated the Soft matter Electrostatic Levitator (SEL) with the neutron scattering source (WAND2) at Oak Ridge National Laboratory. Brayden, Yonghwa, Gil, and Prof. Lee visited HFIR (High Flux Isotope Reactor) at ORNL and integrated the SEL with the neutron beamline in collaboration with ORNL scientists (Drs. Matthis Frontzek, Dr. Dante Quirinale, and Dr. Takeshi Egami). Our success has been featured on the ORNL website: https://www.ornl.gov/news/iowa-state-researchers-use-scientific-wand-suspend-solutions-midair

Lee group will integrate the Soft matter Electrostatic Levitator (SEL) with the neutron scattering source (WAND2) at Oak Ridge National Laboratory. Sai, Brayden, and John will visit HFIR (High Flux Isotope Reactor) at ORNL and integrate the SEL with the neutron beamline in collaboration with ORNL scientists (Drs. Matthis Frontzek, Lisa Debeer-Schmitt, Dr. Dante Quirinale, and Dr. Takeshi Egami). Our successful integration will be followed by neutron scattering experiments in summer 2023.

Lee group successfully integrated the Soft matter Electrostatic Levitator (SEL) with the synchrotron X-ray source (6ID-D beamline) at Advanced Photon Source in collaboration with Dr. Chris Benmore. Three graduate students (Sai Katamreddy, Fahad Obaid, and Daniel Lee) and one undergraduate student (Brayden Berg) joined the integration. Lee group obtained the structural data of three different electrolyte solutions over wide ranges of concentration from undersaturation to extreme supersaturation. The scattering data will provide critical information to unveil the mechanism of the formation of pre-nucleation clusters and nucleation.

Lee group was awarded the NSF EPSCoR Research Fellowship. The fellowship will support the integration of the Soft matter Electrostatic Levitator with two neutron beamlines at Oak Ridge National Laboratory (ORNL). Dr. Lee and his PhD student will spend six months at ORNL over the project period for neutron scattering experiments and molecular dynamic simulations.
