Tunable wrinkling of thin nematic liquid crystal elastomer sheets
Madison S. Krieger, Marcelo A. Dias
Instabilities in thin elastic sheets, such as wrinkles, are of broad interest both from a fundamental viewpoint and also because of their potential for engineering applications. Ne…
Microorganism billiards in closed plane curves
Madison S. Krieger
Recent experiments have shown that many species of microorganisms leave a solid surface at a fixed angle determined by steric interactions and near-field hydrodynamics. This angle…
Microscale locomotion in a nematic liquid crystal
Madison S. Krieger, Saverio E. Spagnolie, Thomas R. Powers
Microorganisms often encounter anisotropy, for example in mucus and biofilms. We study how anisotropy and elasticity of the ambient fluid affects the speed of a swimming microorgan…
Locomotion and transport in a hexatic liquid crystal
Madison S. Krieger, Saverio E. Spagnolie, Thomas R. Powers
The swimming behavior of bacteria and other microorganisms is sensitive to the physical properties of the fluid in which they swim. Mucus, biofilms, and artificial liquid-crystalli…
