Mechanics of mechanochemically responsive elastomers
Mechanochemically responsive (MCR) polymers have been synthesized by incorporating mechanophores – molecules whose chemical reactions are triggered by mechanical force – into conventional polymer networks. Deformation of the MCR polymers applies force on the mechanophores and triggers their reactions, which manifest as phenomena such as changing colors, varying fluorescence and releasing molecu...
متن کاملThe mechanics of explosive dispersal and self-burial in the seeds of the filaree, Erodium cicutarium (Geraniaceae).
The filaree (Erodium cicutarium), a small, flowering plant related to geraniums, possesses a unique seed dispersal mechanism: the plant can fling its seeds up to half a meter away; and the seeds can bury themselves by drilling into the ground, twisting and untwisting in response to changes in humidity. These feats are accomplished using awns, helical bristles of dead but hygroscopically active ...
متن کاملSelf-powered glucose-responsive micropumps.
A self-powered polymeric micropump based on boronate chemistry is described. The pump is triggered by the presence of glucose in ambient conditions and induces convective fluid flows, with pumping velocity proportional to the glucose concentration. The pumping is due to buoyancy convection that originates from reaction-associated heat flux, as verified from experiments and finite difference mod...
متن کاملQuantum Mechanics from Self-Interaction
We explore the possibility that zitterbewegung is the key to a complete understanding of the Dirac theory of electrons. We note that a literal interpretation of the zitterbewegung implies that the electron is the seat of an oscillating bound electromagnetic field similar to de Broglie’s pilot wave. This opens up new possibilities for explaining two major features of quantum mechanics as consequ...
متن کاملStatistical mechanics of self-driven Carnot cycles.
The spontaneous generation and finite-amplitude saturation of sound, in a traveling-wave thermoacoustic engine, are derived as properties of a second-order phase transition. It has previously been argued that this dynamical phase transition, called "onset," has an equivalent equilibrium representation, but the saturation mechanism and scaling were not computed. In this work, the sound modes imp...
