1. A segmented-flow reactor for producing a population of nanocrystals, comprising:
a liquid introduction port;
a gas introduction port; and
a flow path fluidly connected to liquid introduction port and the gas introduction port, the flow path including a first region configured to generate recirculation in a liquid volume, a second region associated with a thermal source, and a third region configured to cool a material within the flow path,
wherein the first region and the second region are thermally insulated from each other,
wherein the third region and the second region are thermally insulated from each other,
wherein the flow path is microfabricated on a substrate, and
wherein the flow path includes a meandering path.
