Synthesis and mechanical response of disordered colloidal micropillars
A method for synthesizing and uniaxially compressing free-standing colloidal micropillars is presented. The mechanical response of the micropillars is strongly dependent upon their initial defect population and water content.
Silver nanoparticle aided self-healing of polyelectrolyte multilayers
Weak polyelectrolyte multilayer films containing silver nanoparticles are shown to have enhanced ability to self-heal when exposed to water when compared to the films assembled without particles.
Strain localization in glassy polymers under cylindrical confinement
Glassy polymeric pillars show strain localization during tensile deformation which is absent in pillars cooled two orders of magnitude faster.
Stretching of assembled nanoparticle helical springs
Assembled nanoparticle helical ribbons have impressive mechanical properties that are predictable through surface and elastic energies.
Mechanotunable monatomic metal structures at graphene edges
Graphene edge is an efficient one-dimensional template for low-dimensional, mechanotunable metal structures such as chains, rings and helices.
Conformational interchange of a carbohydrate by mechanical compression at the air–water interface
Conformational interchange of a fluorescent-labelled carbohydrate by macroscopic mechanical force.
