摘要： Ultra-high temperature carbide (UHTC) foams and methods of fabricating and using the same are provided. The UHTC foams are produced in a three-step process, including UHTC slurry preparation, freeze-drying, and spark plasma sintering (SPS). The fabrication methods allow for the production of any kind of single- or multi-component UHTC foam, while also providing flexibility in the shape and size of the UHTC foams to produce near-net-shape components.

摘要： The present invention relates to a process for preparing a humidity sensor based on resistive type porous Magnesium Ferrite (MgFe2O4) pellets and a humidity sensor thereof. More particularly, the present invention includes a synthesis process of preparing 30 to 40% porous MgFe2O4 pellets. The process further includes making Ohmic contacts on the porous MgFe2O4 pellets. The process is very cost effective and optimized to keep the resistance of the porous MgFe2O4 pellets in the range 200-300 MΩ. Further, the response and recovery time of the porous MgFe2O4 pellets to humidity is in the range of few seconds only. Further, the porous MgFe2O4 pellets can be used for humidity sensing for more than 12 months. Due to resistance stability even after long-term exposure in humidity, the porous MgFe2O4 pellets do not require flash heating. Further, the humidity sensor prepared according to the process is highly sensitive towards relative humidity changes as the same is based on the measurement of resistance changes as compared to known humidity sensors which are based on the measurement of capacitance changes.

摘要： In one embodiment, a membrane of proton-electron conducting ceramics that is useful for the conversion of a hydrocarbon and steam to hydrogen has a porous support coated with a film of a Perovskite-type oxide. By including the Zr and M in the oxide in place of Ce, the stability can be improved while maintaining sufficient hydrogen flux for efficient generation of hydrogen. In this manner, the conversion can be carried out by performing steam methane reforming (SMR) and/or water-gas shift reactions (WGS) at high temperature, where the conversion of CO to CO2 and H2 is driven by the removal of H2 to give high conversions.

摘要： A porous discriminating layer is formed on a ceramic support having at least one porous wall by (a) establishing a flow of a gas stream containing agglomerates of particles and (b) calcining said deposited layer to form the discriminating layer. At least a portion of the particles are of a sinter-resistant material or a sinter-resistant material precursor. The particles have a size from 0.01 to 5 microns and the agglomerates have a size of from 10 to 200 microns. This method is an inexpensive and effective route to forming a discriminating layer onto the porous wall.
