The swelling and shrinking of spherical thermo-responsive hydrogels
Matthew D. Butler, Thomas D. Montenegro-Johnson
Thermo-responsive hydrogels are a promising material for creating controllable actuators for use in micro-scale devices, since they expand and contract significantly (absorbing or…
The other optimal Stokes drag profile
Thomas D. Montenegro-Johnson, Eric Lauga
The lowest drag shape of fixed volume in Stokes flow has been known for some 40 years. It is front-back symmetric and similar to an American football with ends tangent to a cone of…
Spermatozoa scattering by a microchannel feature: an elastohydrodynamic model
Thomas Montenegro-Johnson, Hermes Gadelha, David J. Smith
Sperm traverse their microenvironment through viscous fluid by propagating flagellar waves; the waveform emerges as a consequence of elastic structure, internal active moments, and…
The Optimal Swimming Sheet
Thomas D. Montenegro-Johnson, Eric Lauga
Propulsion at microscopic scales is often achieved through propagating traveling waves along hair-like organelles called flagella. Taylor's two-dimensional swimming sheet model is…
