20080296808 | Apparatus and Method for Producing Electrospun Fibers - An apparatus for making electrspun fibers comprises a collector that may be submerged in a coagulation bath. The collector may be automatically movable between a first position and a second position, wherein at least a portion of the collected fibers are submerged in a coagulation bath in the first position and spaced apart from the coagulation bath in the second position. The collector may be a rotating collector. A process for making electrospun fibers comprises electrospinning a dispersion and collecting a plurality of electrospun fibers, followed by submerging the collected fibers in a coagulation bath. | 12-04-2008 |

20120135234 | BIODEGRADABLE NANOFIBERS AND IMPLEMENTATIONS THEREOF - A fibrous product is described that comprises biodegradable fibers on a substrate. The fibers originate from a deposition solution that comprises a protein-based component and a carrier polymer component, each configured so that the resulting deposition solution can be deposited using electro-deposition techniques. In one embodiment, the proteins in the deposition solution are denatured in a manner that modifies the viscosity of the resulting deposition solution so that the deposition solution is compatible with electro-spinning. | 05-31-2012 |
20120282484 | METAL AND CERAMIC NANOFIBERS - Provided herein are nanofibers and processes of preparing nanofibers. In some instances, the nanofibers are metal and/or ceramic nanofibers.
