Graphene fibres are continuously prepared from universal graphene oxide precursors by a novel hydrogel-assisted spinning method. With assistance of a rolling process, meters of ribbon-like GFs, or GRs with improved conductivity, tensile strength, and a long-range ordered compact layer structure are successfully obtained. Furthermore, we refined our spinning process to obtained elastic GRs with ...

This study presents a method for fabrication of ultrafine polymeric nanofibers as well as nano/micro particles utilizing centrifugal and electrostatic forces simultaneously. To reduce the diameter and variety of nanofibers produced from solid state polymerized PA66, a unique electrocentrifuge spinning device was utilized with a rotating nozzle and collector, while the fabrication process (spinn...

Yarns produced by Japanese Open-end BD-200 spinning machines give these major advantages: (1) They are somewhat stronger than yarns spun by Czecho BD-200's. (2) They are almost as strong as yarns spun by ring spinning machines. This strength is obtainable without raising the cost of raw cotton if the right fore-spinning processes and spinning conditions are used. (3) They have maximum strength ...

Knowledge of current business processes is a critical requirement for organizational initiatives like compliance management, regulatory reporting, process optimization, reengineering the IT systems and outsourcing. Existing process discovery techniques expect process execution information or event logs while organization’s business processes are often executed on heterogeneous systems across di...

Carbon fibers are widely used in many industrial applications due the fact of their excellent properties. Carbonaceous mesophases are liquid crystalline precursor materials that can be spun into high performance carbon fibers using the melt spinning process, which is a flow cascade consisting of pressure driven flow-converging die flow-free surface extensional spinline flow that modifies the pr...
