Tuning nonlinear waves in nonreciprocal active filaments
Sami C. Al-Izzi, Jack Binysh, Yao Du +2
The instabilities of slender structures power biological locomotion across scales, and offer a compelling method to actuate soft robots. Nonreciprocal elastic solids have been foun…
Nonreciprocal buckling makes active filaments polyfunctional
Sami C. Al-Izzi, Yao Du, Jonas Veenstra +5
Active filaments are a workhorse for propulsion and actuation across biology, soft robotics and mechanical metamaterials. However, artificial active rods suffer from limited robust…
A Twist On Active Membranes: Odd Mechanics, Spontaneous Flows and Shape Instabilities
Sami C. Al-Izzi, Gareth P. Alexander
Living systems are chiral on multiple scales, from constituent biopolymers to large scale morphology, and their active mechanics is both driven by chiral components and serves to g…
Morphodynamics of Active Nematic Fluid Surfaces
Sami C. Al-Izzi, Richard G. Morris
Morphodynamic equations governing the behaviour of active nematic fluids on deformable curved surfaces are constructed in the large deformation limit. Emphasis is placed on the for…
Dynamics of passive and active membrane tubes
Sami C. Al-Izzi, Pierre Sens, Matthew S. Turner +1
Utilising Onsager's variational formulation, we derive dynamical equations for the relaxation of a fluid membrane tube in the limit of small deformation, allowing for a contrast of…
Measuring Gaussian rigidity using curved substrates
Piermarco Fonda, Sami C. Al-Izzi, Luca Giomi +1
The Gaussian (saddle splay) rigidity of fluid membranes controls their equilibrium topology but is notoriously difficult to measure. In lipid mixtures, typical of living cells, lin…
