Design and Testing of a Hovercraft with Electroaerodynamic Propulsion
Electroaerodynamic (EAD) multistaged ducted (MSD) thrusters are a novel solid-state thruster architecture that has been shown to provide order-of-magnitude improvements in thrust density compared to single-stage EAD thrusters. This makes MSD thrusters well-suited for use in EAD hovercraft, where …

Advances in electroaerodynamic thrusters for aircraft propulsion
… third study is a theoretical investigation of multistaged ducted (MSD) thrusters containing several serially-stacked EAD stages enclosed in a duct. The duct also includes an inlet and a nozzle and is hypothesized to provide a thrust component similar to that in ducted fans. Combining momentum …

Split-feed counterflow reverse osmosis for brine concentration
… provides insights for configuring and optimizing multistaged systems. Additionally, a parametric analysis of membrane parameters provides direction for the development of CFRO-specific membranes. Two existing configurations of CFRO are discussed, and compared with a new third configuration, split …

Ascribed and Acquired Identities: Women's Collective Renegotiation of Social and Personal Identity Following Brain Injury
… invokes? The study design was collaborative, multistaged and iterative. Analysis was thematic and primarily followed an interpretive biographical method, however narrative, epiphanic and critical theory approaches were also employed, with the aim of understanding the intersections of personal …

Towards Practical Fixed-Wing Aircraft with Electroaerodynamic Propulsion
… a family of uncrewed aircraft powered by multistaged ducted (MSD) EAD thrusters for a package delivery mission, and an uncrewed MSD-powered monoplane for a surveillance mission. MSD thrusters are more powerful and efficient than equivalent unducted EAD thrusters, in part because the duct …

Novel internally-staged ultrafiltration for protein purification
A new ultrafiltration technique based on a multimembrane stack has been developed to fractionate proteins closer in molecular weight than conventionally possible. The technique is illustrated here by obtaining a pure protein product from a binary protein mixture. By employing membranes in series …
