Fabrication and characterization of sintered porous glass emitters for electrospray propulsion
… 4[mu]m are then deposited into these molds and sintered to form porous columns with a diameter of 25[mu]mt, 50[mu]rm, or 75[mu]m. These columns become emitters when the device layer is etched with XeF₂. A porous sintered glass piece is tested as an emitter to characterize the suitability of the …

Development and characterization of sintered porous bioactive glass scaffolds for medical application
There is an ongoing effort to innovate engineering materials that are used in medical applications to support, enhance, or replace damaged tissue or perform a biological function. This study focuses on researching bioactive glass scaffolds resembling natural trabecular bone tissues that are widely …

Experimental design for study of nucleate boiling in porous structures
… required to initiate nucleate boiling inside porous wicks is not well understood in practice. This thesis reports the design of an experimental setup for investigating the onset of vapor nucleation in sintered porous structures. Pressure sensing was evaluated as an effective means of detecting …

Material and fabrication developments in the ion-electrospray propulsion system
… of operation. Additionally, a new monodisperse, sintered porous silica ceramic was developed for use in emitter substrates. The highly-modifiable, photocurable ceramic resin used to cast the emitter substrates is a strong contender to replace the state-of-the-art borosilicate glass chips. An …

The effect of a magnesia based additive on fly ash depostition in a chain-grate boiler system.
… samples with Lycal injection showed lightly sintered, porous, friable textures compared to the highly sintered, fused and dense structures for samples without Lycal injection. The effect of Lycal on the softening behaviour of reconstituted deposit samples and various components of ash was …
