Frustrated shapes of solid domains in fluid membrane vesicles: From rolls and folds to crumples and wrinkles
Geunwoong Jeon, Anthony N. A. Prempeh, Maria M. Santore +1
Fluid-solid composite vesicles, comprising 2D solid domains integrated into a topologically-closed fluid bilayer membrane, exhibit complex morphologies arising from the geometric f…
Sculpting 2D Crystals via Membrane Contractions before and during Solidification
Hao Wan, Geunwoong Jeon, Gregory M. Grason +1
When phospholipids crystallize within the otherwise fluid membranes of giant unilamellar vesicles, the resulting molecularly-thin "2D" solids exhibit great variety in their morphol…
Thermal Preconditioning of Membrane Stress to Control the Shapes of Ultrathin Crystals
Hao Wan, Geunwoong Jeon, Gregory M. Grason +1
We employ the phospholipid bilayer membranes of giant unilamellar vesicles as a free-standing environment for the growth of membrane-integrated ultrathin phospholipid crystals poss…
Shape equilibria of vesicles with rigid planar inclusions
Geunwoong Jeon, Justin Fagnoni, Hao Wan +2
Motivated by recent studies of two-phase lipid vesicles possessing 2D solid domains integrated within a fluid bilayer phase, we study the shape equilibria of closed vesicles posses…
A computational study of chemically heterogeneous particles: patchy vs. uniform particles in shear flow
Marina Bendersky, Maria M. Santore, Jeffrey M. Davis
The adhesion of flowing particles and biological cells over fixed collecting surfaces is vitally important in diverse situations and potentially controlled by small-scale surface h…
