Abstract: A detector is for identifying chemicals in a sample. The detector may include a photodetector comprising SiC semiconductor material and configured to have an acceptor energy band of range Ea−ΔEa to Ea+ΔEa. The SiC semiconductor material may be doped with a dopant to exceed a threshold dopant concentration level. The photodetector may be configured to receive fluorescence information from the sample.

Abstract: A laser-assisted microfluidics manufacturing process has been developed for the fabrication of additively manufactured structures. Roll-to-roll manufacturing is enhanced by the use of a laser-assisted electrospray printhead positioned above the flexible substrate. The laser electrospray printhead sprays microdroplets containing nanoparticles onto the substrate to form both thin-film and structural layers. As the substrate moves, the nanoparticles are sintered using a laser beam directed by the laser electrospray printhead onto the substrate.

Abstract: A fluid mixing method using a micromixing apparatus which includes a mixing microchannel having a channel length and a continuously variable channel width defined by a first sidewall surface and an opposing second sidewall surface. The channel width varies from a minimum channel width h to a maximum channel width H in a ratio of H:h≧1.1:1.0. A first inlet injects a first fluid and a second inlet a second fluid into the mixing microchannel which both flow in a flow direction in the mixing microchannel along the channel length. The first sidewall surface includes first curved surface portions and the second sidewall surface includes second curved surface portions. The first and second curved surface portions are non-overlapping to provide the variable channel width. The flow velocity profile is passively varied and exclusively controlled by the continuously variable channel width.
