Materials Science and Engineering Ph.D. student John Chmiola’s (advisor: Yury Gogotsi) paper, “Anomalous increase in carbon capacitance at pore sizes less than 1 nanometer,” (J. Chmiola, G. Yushin, Y. Gogotsi, C. Portet, P. Simon, P.L. Taberna) Science 313 (5794): 1760-1763 Sept. 22, 2006) has been ranked #17 in the Top 100 Nanomedicine Publications, according to the Ion Channel Media Group.
On the media group’s Nanomedicine Research Portal Web site, Chmiola’s article is listed among 100 other articles classified as the most influential publications in the nanomedicine field in 2006. Publications are scored based upon the frequency that visitors to the Web site read the particular article. That score is then scaled by a citation score calculated from the citation history of the journal and the principal investigator.
Under the advisement of MSE Professor and Director of the Drexel Nanotechnology Institute Dr. Yury Gogotsi, Chmiola, postdoctoral researcher Cristelle Portet and MSE Research Assistant Professor Gleb Yushin conducted supercapacitor research dealing with increasing the efficiency of these energy storage devices that are most commonly used in backup power applications. Chmiola and colleagues found that pore sizes in supercapacitor electrode material could be reduced to about one nanometer in diameter, leading to lighter, more powerful supercapacitors. These versatile devices are also finding increased usage in personal electronic devices, mobile phones and hybrid electric/fuel cell vehicles for their improved power over batteries.
