Dr. Paulenova's radiochemistry research group operates the TRansUranic Element LABoratory (TRUELAB), located in the OSU Radiation Center. The elements beyond uranium in the Periodic Table of Elements (traditionally called TRU), especially plutonium and neptunium, have an intriguing chemistry, hence TRUE (true data on TRU Elements) become the name of our laboratory.
TRUELAB is a state-of-art laboratory equipped with the latest chemical analytical equipment for speciation studies of metals in aqueous, organic and micellar media. We are focused on chemistry of actinides and fission products, primarily lanthanides and technetium and molybdenum; however, also chemistry of other metals are of our great interest.
While the optical spectroscopy and chromatography instrumentation is centralized in the rooms of the TRUELAB, the radiodetection and irradiation instrumentation is shared with other research residents of the Radiation Center.
