  • Incident Infrared laser light (red) on a gold nanoshell (about 150 nm in diameter) coaxes electrons to stream (blue arrows) out of the surface; the electrons are then measured by a detector (cyan disc). A low-energy stream of electrons has many applications for electron imaging.  The dashed red line represents an external Electric field along the laser’s polarization axis. The diffuse red glow on the sides of the shell represent the near-field enhancements due to plasmonic effects.
    JILA researchers have created a laser-controlled "electron faucet", which emits a stable stream of low-energy electrons. These faucets have many applications for ultrafast switches and ultrafast electron imaging. The electron faucet starts with gold, spherical nanoshells.
  • The ultimate radar detector (a.k.a. the 3D velocity map-imaging apparatus).
    The Nesbitt group has invented a nifty technique for exploring the physics and chemistry of a gas interacting with molecules on the surface of a liquid. The group originally envisioned the technique because it’s impossible to overestimate the importance of understanding surface chemistry. For instance, ozone depletion in the atmosphere occurs because of chemical reactions of hydrochloric acid on the surface of ice crystals and aerosols in the upper atmosphere. Interstellar chemistry takes place on the surface of tiny grains of dust.

    The American Chemical Society (ACS) has awarded David Nesbitt the 2017 E. Bright Wilson Award in Spectroscopy. The award, sponsored by the ACS Division of Physical Chemistry, recognizes outstanding accomplishments in fundamental or applied spectroscopy in chemistry. It consists of $5,000 and a certificate.
