CBE Doctoral Dissertation Defense: “Designing Solvent-Based Order Parameters for Characterizing Binding of Surfaces with Different Hydrophobicity Using Molecular Dynamics Simulations” (Jun Lu)

Greenberg Lounge (Room 114), Skirkanich Hall 210 South 33rd Street, Philadelphia

Abstract: Life is dependent on water: most self-assembly and binding processes of biomolecules take place in water. Water-mediated interactions are an essential driving force behind these processes, which is largely affected by the hydrophobicity of the binding surfaces. As many biomolecular binding interfaces are amphiphilic, the hydrophobic interactions are largely affected by polar and charged […]

CBE Doctoral Dissertation Defense: “Structure and transport properties of nanoporous polymers derived from lyotropic mesophases” (Christopher Johnson)

Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia

Abstract: Burgeoning energy and water scarcity challenges motivate the development of new membrane materials for charge transport as well as chemical and water separations. This in turn requires an improved understanding of the physics that govern charged and uncharged solute transport in membranes, and particularly the motion of such species in nm-scale confinement in polymeric […]

CBE Doctoral Dissertation Defense: “Context-Dependent Protein Surface Hydrophilicity” (Lilia F. Escobedo)

Vagelos Institute for Energy Science and Technology, Room 121 231 S 34th Street, Philadelphia

Abstract: Proteins perform many important biological functions while also avoiding fouling in an aqueous and crowded cellular environment. Their surfaces have evolved to be both chemically heterogeneous (containing nonpolar, polar, and charged groups) as well as hydrophilic. While nonpolar groups are known to induce hydrophobicity, surface heterogeneity has been found to enhance hydrophilicity and the […]
