Electrospinning of biphasic biopolymer and polymer : a feasibility and characterization study
Electrospinning of polymeric materials have been experimented to achieve nanoscaled diameters. The approaches to the current study are to combine a natural material such as collagen with synthetic materials and determine if the interactions between the materials can be used in the electrospinning …

Electrospinning as a Processing Method for Electroactive Polymers and Composites
Electrospinning was examined for its potential to create functional materials. Three distinct electroactive materials were electrospun into fibers and fiber mats and then characterized with the intent of determining their utility in aerospace and biomedical applications such as micro-air vehicles …

Novel Apparatus to Control Electrospinning Fiber Orientation for the Production of Tissue Engineering Scaffolds
The conception of electrospinning can trace its roots back more than 400 years, when it was observed that rubbed amber can deform a droplet of water on a smooth surface, and is based upon simple concepts of charge separation and surface tension. Since that time, considerable effort has been …

Patient-specific thoracic endovascular aoratic repair (TEVAR)
… of the patient. After investigating the range of electrospinning shape capabilities on idealised stent-graft geometries (straight, tapered, elliptical, and curved), CT scans was used to create blood and aortic models of an abdominal aortic aneurysm. The former was used to design a patientspecific …

Parallel nano-manufacturing via electro-hydrodynamic jetting from externally-fed emitter arrays
… The most common production process, known as electrospinning, involves pumping a viscous, conducting liquid at very low flow rates through a syringe needle in a strong electric field. The emitted charged jet is stretched and whipped extensively creating fibers with diameters as small as tens …
