November 22, 2010
Michael Mante - Successfully Defended Thesis "Near Equilibrium Dissolution of Calcite using a Flow-Through Reactor"
October 7, 2010
Mike Smith will be presenting his research at the Spring 2011 ACS Meeting. Mike's research is focussing on the chemical kinetics of crystallographically-inequivalent surfaces of calcite minerals.

Man Xu will give an oral presentation "Solute-controlled dissolution thresholding at near-equilibrium calcite-water interfaces" on her latest research on step edge kinetics on calcite surfaces by AFM. She will be speaking at the symposium entitled "Nanoscale Insights into Aqueous and High Temperature Geochemistry", at the 2010 American Geophysical Union Meeting on December 13-17 in San Francisco (http://www.agu.org/meetings/fm10/)

Symposium on Pushing experimental and computational limits: A prospective look at mineral-fluid interfaces at the 2010 V.M. Goldschmidt Conference in Knoxville, Tennessee, June 13-18, 2010.
Dr. Higgins along with Drs. Andrew Stack of Oak Ridge National Laboratory and Tom Trainor of the University of Alaska-Fairbanks organized this very exciting symposium. Dr. Higgins presented a paper titled "Scanning Probe Microscopy and mineral-water interfaces: Have we reached a limit?" in this symposium along with his co-authors Man Xu, Kevin Knauss, Scott Lea, Pablo Cubillas and Kevin Rosso.

More than 130 Wright State students shared their research activities with fellow students and faculty at the Celebration of Research, Scholarship and Creative Activities in the Student Union Apollo Room. Michael Mante and Dennis Lennaerts presented their posters at this event which was attended by the WSU President, Dr. David Hopkins. Below, Dennis (left) is shown explaining to Dr. Hopkins (center) and a distinguished guest how Sr and Ca are distributed in barite precipitates that form in seawater.
Dr. Man Xu joined the Higgins group in June 2009 as a postdoctoral research associate. Dr. Xu received her PhD in Environmental Science from Ohio State University under the direction of Prof. Heather C. Allen followed by a postdoctoral position in the laboratory of Prof. Kenneth Eisenthal at Columbia University. Dr. Xu is currently investigating carbonate dissolution kinetics under fluid conditions relevant to geologic CO2 sequestration.
