Energy can be carried in a number of ways: by electrons, the particles that underpin all modern electronics, as well as by quasiparticles, the results of different particles interacting with one another at the quantum level. Columbia chemist Milan Delor has been watching these different forms of ene rgy flow with an instrument called stroboSCAT, a unique microscope that uses strobe-like light pulses to capture particles and quasiparticles as they move through different materials. ...read more read less
