Shape-Directed Dynamics of Active Colloids

Shape-Directed Dynamics of Active Colloids

We showed how particle shape can be used to encode complex dynamical behaviors into colloidal particles powered by induced-charge electrophoresis.

Self-Assembled Three-Dimensional Chiral Colloidal Architecture: Uniquely Left or Uniquely Right Handed

We used DNA nanotechnology to self-assemble uniquely left handed or right handed micron scale colloidal clusters — a step toward freeform architecture.

A Silicon Ratchet to Produce Power from Below-Bandgap Photons

A Silicon Ratchet to Produce Power from Below-Bandgap Photons

We show, with a 3D model of silicon under incoherent THz irradiation, that below-bandgap excitations (free carrier or intraband absorptions) can do useful work by exciting, i.e. flashing, electrons in and out of a structurally embedded ratchet potential.

A Light-Responsive Organic Electron Flashing Ratchet

We have fabricated a room-temperature flashing electron ratchet (only the second such device to ever appear in the literature) from a blend of conjugated organic materials; upon the application of a shaped, oscillating gate potential, our devices not only produce a source-drain current in the absence of a source-drain bias, but also produce power.

The excellent strength-to-weight ratio of polypropylene tubing enables construction of exoskeletons inspired by spiders, ants, and water striders.
