A microwave plasma apparatus for processing a material includes a plasma chamber, a microwave radiation source, and a waveguide guiding microwave radiation from the microwave radiation source to the plasma chamber. A process gas flows through the plasma chamber and the microwave radiation couples to the process gas to produce a plasma jet. A process material is introduced to the plasma chamber, becomes entrained in the plasma jet, and is thereby transformed to a stream of product material droplets or particles. The product material droplets or particles are substantially more uniform in size, velocity, temperature, and melt state than are droplets or particles produced by prior devices.

Microwave plasma apparatus and method for materials processing

The present disclosure relates to in-situ, line-of-sight measurements of partial pressure and temperature associated with at least one flow channel of a fuel cell. Tunable diode laser absorption spectroscopy (TDLAS) is employed for measurements for which water transition states sensitive to temperature and partial pressure are utilized. Measurements are achievable for a fuel cell operating under both steady-state and time-varying load conditions. For steady-state operation, the water partial pressure increases with increasing current density on a cathode side of the fuel cell due to production of water by electrochemical reaction. Temperature in a gas phase remains relatively constant since the fuel cell housing temperature is controlled externally. For non-steady-state operation of the fuel cell through a time-varying current profile, the water partial pressure responds to the load changes rapidly and follows a current profile. The gas temperature varies in response to the dynamic loading and departures from steady-state conditions become more apparent at higher fuel cell operating temperatures.

Fiber optic based in-situ diagnostics for PEM fuel cells

The apparatus for the thermal spray delivery of a precursor solution comprises a first solution reservoir, a second solution reservoir, singular or multiple atomizing liquid injector(s) disposed in fluid communication with the reservoirs, a flame source configured to direct a spray from the atomizing liquid injector to a substrate, and a thermal control device disposed in thermal communication with the substrate. The method of depositing a precursor solution at a substrate to form a coating comprises maintaining a substrate at a pre-selected temperature, delivering the precursor solution from a reservoir bank, atomizing the precursor solution, injecting the atomized precursor solution into a flame, and directing the flame to the substrate.

Apparatus and method for solution plasma spraying

A system for testing the electrical conductivity of printed traces, on multiple surfaces, of a printed wiring board using non-contacting probes. The non-contact probes generate a plasma in a plasma generating chamber that is used to apply a voltage to the printed wiring board. A measurement circuit determines the magnitude of the voltage on the printed wiring board.
