Continuous Granulation with a Twin-Screw Extruder

Continuous Shear Roll Milling of Gun Propellants

The continuous shear roll milling can be used for the processing and granulation of gun propellants. Here a mathematical model of the continuous shear roll milling process will be presented along with experimental data collected on live and simulant propellant formulations. The role of the flow boundary condition will be shown to be critical in the processability analysis. The safety aspects wi...

CONTINUOUS ROLL-TO-ROLL SERPENTINE DEPOSITION FOR HIGH THROUGHPUT a-Si PV MANUFACTURING

In order to further improve the economies of scale which are inherent in ECD’s continuous roil-to-roll amorphous silicon alloy solar cell manufacturing process, we have developed a concept for a serpentine web plasma CVD deposition process to maximize throughput while keeping the size of the deposition chambers small. When this technique is incorporated into a continuous rollto-roll PV manufact...

Roll-to-roll continuous patterning and transfer of graphene via dispersive adhesion.

We present a roll-to-roll, continuous patterning and transfer of graphene sheets capable of residue-free and fast patterning. The graphene sheet is supported with dispersive adhesion. Graphene is continuously patterned by the difference in adhesion forces with a pre-defined embossed roller. The patterned graphene sheet adheres to the polyethylene terephthalate (PET)/silicone with very low stren...

Large-area, continuous roll-to-roll nanoimprinting with PFPE composite molds.

Successful implementation of a high-speed roll-to-roll nanoimprinting technique for continuous manufacturing of electronic devices has been hindered due to lack of simple substrate preparation steps, as well as lack of durable and long lasting molds that can faithfully replicate nanofeatures with high fidelity over hundreds of imprinting cycles. In this work, we demonstrate large-area high-spee...
