Debra R. Rolison (* 1954 in Sioux City , Iowa ) is an American chemist ( electrochemistry , nanosciences ). She develops multifunctional nanoarchitectures especially for catalysis, energy storage and conversion, porous magnets, biomolecular composite materials and sensors.

Rolison grew up in South Florida and studied at Florida Atlantic University with a bachelor's degree in 1975 (1972 to 1975 she was Faculty Scholar there) and received her doctorate in 1980 at the University of North Carolina at Chapel Hill with Royce W. Murray . She then went to the Naval Research Laboratory (NRL), where she founded the Advanced Electrochemical Materials Department in 1999. Since 2000 she has been an adjunct professor at the University of Utah .

She developed electrodes modified by a surface coating with zeolites and polymers, whereby the zeolite grid selects the access of molecules according to size, charge and shape. Conversely, this is also used for the synthesis of electrode-modified zeolites, with transition metal ions or complexes in the zeolite lattice.

Together with colleagues, she developed a nickel-zinc accumulator , the performance of which comes close to that of lithium-ion batteries, but has weight advantages and would be cheaper. In contrast to conventional accumulators with zinc powder, they have a three-dimensional porous structure on the anode, which means that when charging (zinc oxide formation), the contacts and an even current distribution are maintained and dendrite structures do not form at points of high current flow Main problem of previous nickel-zinc accumulators. Due to the dendrites, there is a risk of short circuits and thus a limited service life and reduced performance.

She wrote over 200 scientific articles and 24 patents.

In 2011 she received the American Chemical Society's Prize for Chemistry of Materials and the Hillebrand Prize of the Chemical Society of Washington, in 2012 the CN Reilley Award of the Society for Electroanalytical Chemistry and in 2018 the William H. Nichols Medal . She is a Fellow of the American Association for the Advancement of Science , the American Chemical Society, and the Materials Research Society .

She is or was on the editorial board of Analytical Chemistry, Langmuir, Journal of Electroanalytical Chemistry, Advanced Energy Materials, Nano Letters , the Encyclopedia of Nanoscience and Nanotechnology, and the Annual Review in Analytical Chemistry .
