The cost efficient, high throughput production of metaland semiconductor alloys is the foundation of many advanced technologies. With the development of the Ribbon Growth on Substrate (RGS) technology, a new crystallization technique is available that allows the controlled, high crystallization rate production of silicon wafers and advanced metal-silicide alloys. Compared to other crystallizati...

Commercial grade polyethylene is melt electrospun from a thin film of unconfined molten polymer on a heated, electrically-grounded plate. Under the influence of an applied electric field, the melt spontaneously forms fingering perturbations at the plate edge which then evolve into emitting fiber-forming jets. Jet-to-jet spacing (∼5mm), which is dependent on the applied voltage amplitude, is in ...

The aim of this work was to develop and characterize polyurethane-based shape memory polymer filament yarns a suitable diameter thermo-mechanical performance for use in tailored multi-sectorial applications. Different compositions – pure polyurethane composites with 0.3 0.5 wt.% multi-walled carbon nanotubes or black as additives were studied. Filaments obtained using melt spinning process that...
