Kedves Kollégák, kedves Érdeklődők!
Tisztelettel értesítem, hogy július 7-én (csütörtök) 14 órakor, az A épület 8-as termében Dr. Dirk Gillespie (Rush University Medical Center, Chicago, USA) vendégelőadást tart Charge lnversion in the Electrical Double Layer: Applications and Theory címmel.
Az előadás nyelve angol, rövid összefoglalóia:
Recent advances in the theoretical underpinnings of charge inversion in the electrical double Layer and its practical applications in nanofluidic devices are discussed. ln charge inversion, more counterions than necessary to neutralize a surface charge accumulate, leading to an increase in co-ions in the second Layer of ions near the surface. When electrolytes that produce charge inversion are confined in a nanoscale slit between two charged walls, this can reverse the flow of fluid. We have recently used this phenomenon in nanofluidic devices for practical applications and can also to better understand the physics of charge inversion. To define the statistical mechanical origins of charge inversion, we have recently used the primitive model of electrolytes and classical density functional theory of fluids to show how different components of the electrochemical potential combi ne to produce charge inversion.
Az előadóról:
Dr. Dirk Gillespie is an Associate Professor at Rush University Medical Center in Chicago. His main focus of study is ions in confining geometries, ranging from biological ion channels and Ca2+ microdomains to fabricated nanofluidic devices. He is specifically interested in how nanoscale ion-ion correlations can produce macroscale effects. After earning degrees in Mathematics from Johns Hopkins and Northwestern Universities and his PhD in Physiology from Rush University in 1999, Dr. Gillespie was a postdoctoral fellow at the University of Texas at Austin (Mathematics) and the University of Miami School of Medici ne (Physiology/Biophysics). He joined the faculty of the Department of Physiology and Biophysics at Rush University Medical Center in 2003 and has since published more than go scientific papers.
