  • Tom Perkins 2017
    Fellow Tom Perkins has won a 2017 Governor鈥檚 Award for High-Impact Research. Perkins will receive the award from Governor John Hickenlooper at an event sponsored by the CO-LABS consortium at the Denver Museum of Nature and Science on October 5, 2017. This year鈥檚 ninth annual event will honor Colorado鈥檚 top scientists and engineers for projects having a significant impact on society.
  • Laser light knocks both neutral and charged bismuth atoms off a disk of bismuth metal.
    Graduate student Mike Thompson of the Weber group wants to understand the basic science of taking carbon dioxide (CO2) produced by burning fossil fuels and converting it back into useful fuels. People could then use these fuels to generate electricity, heat homes and office buildings, power automobiles and trains, fly airplanes, and drive the industrial processes of modern life.
  • Artist鈥檚 conception of an infrared frequency comb 鈥渨atching鈥 the reaction of a molecule.
    Using frequency comb spectroscopy, the Ye group has directly observed transient intermediate steps in a chemical reaction that plays a key role in combustion, atmospheric chemistry, and chemistry in the interstellar medium. The group was able to make this first-ever measurement because frequency combs generate a wide range of laser wavelengths in ultrafast pulses. These pulses made it possible for the researchers to 鈥渟ee鈥 every step in the chemical reaction of OH + CO 鈫 HOCO 鈫 CO2 + H.
  • 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鈥檚 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.
