Electrospun TiO2 nanofibers for gas sensing applications

Kim D.Y., Kim I-D, Rothschild A., Tuller H.L., Kim D.Y., Kim I-D, Jo S.M., Korea Institute of Science and Technology, KR

TiO2 fiber mats were deposited onto Al2O3 substrates with interdigitated Pt electrodes by means of electrospinning from a solution of DMF and PVAc synthesized using bulk radical polymerization of titanium propoxide and acetic acid as [...]

Electrospun Microfiber Tubes and Self-Assembling Peptides Stimulate Neural Regeneration in Rat Sciatic Nerve Transections

Gelain F., Panseri S., Modica L., Taraballi F., Lowery J., Vescovi A., University of Milan-Bicocca, IT

Peripheral nerve injury is still a traumatic pathology that may impair patient’s movements by interrupting his motor-sensory pathways. New synthetic nerve grafts comprising electrospun tubes and tailored self-assembling peptides are used in our study to [...]

Ferritin-based Hybrid Nanofibers with Magnetic Properties

Shin M.K., Cho Y., Kim S.J., Hanyang University, KR

There has been intense interest in polymeric nanocomposites using nanoparticles, nanowires, and nanotubes, because nanocomposites possess improved physical properties versus the unmodified polymer. In particular, a mixture of polymers and nanoparticles can form flexible nanocomposites [...]

Kim D.Y., Kim I-D, Rothschild A., Tuller H.L., Kim D.Y., Kim I-D, Jo S.M., Korea Institute of Science and Technology, KR

TiO2 fiber mats were deposited onto Al2O3 substrates with interdigitated Pt electrodes by means of electrospinning from a solution of DMF and PVAc synthesized using bulk radical polymerization of titanium propoxide and acetic acid as [...]

Polymer Nanofibers from Multiple Jets Produced on a Porous Surface by Electrospinning

Dosunmu O.O., Chase G.G., Varabhas J.S., Kataphinan W., Reneker D.H., Microscale Physiochemical Engineering Center, US

Electrospinning involves the uniaxial stretching of a viscoelastic jet derived from a polymer solution or melt. The stretching is because of a very high voltage applied to the polymer solution (or melt) relative to a [...]

Production of Conducting Polymer Nanowires for Use as Intravascular Neural Recording Electrodes

Ruddy B., Watanabe H., Hunter I., Llinás R.R., Massachusetts Institute of Technology, US

A crucial factor limiting the adoption of brain-machine interfaces is the invasiveness of conventional microelectrode arrays. Recently, Llinas et al. proposed a new, less invasive form of microelectrode array, utilizing sub-micrometer insulated platinum wires placed [...]

Molecular orientation in electrospun poly(butylene terephthalate) nanofibers

Catalani L.H., Collins G., Jaffe M., University of Sao Paulo, BR

In this work, poly(butylene terephthalate) (PBT) electrospun fibers were produced by conventional electrospinning technique. All typical parameters dependences were studied. Typical behavior was observed for all parameters. In addition, we have analyzed molecular features of [...]

Patterned nanofiber meshes for biomedical applications

Neves N.M., Campos R., Pedro A., Cunha J., Macedo F., Reis R.L., University of Minho, PT

The typical end-product of the electrospinning process is a randomly aligned fibre mesh or membrane. This is a result of the electric field generated between the drop of polymer solution at the needle and the [...]

Improvement of Polycaprolactone Nanofibers Topographies: Testing the Influence in Osteoblastic Proliferation

Martins A., Cunha J., Macedo F., Reis R.L., Neves N.M., University of Minho, PT

The nanofiber technology of present interest focuses on the electrospinning technique, which conveniently allows the preparation of fibrous materials with very fine diameters ranging from submicron to several nanometers. With the ability to form nanofibrous [...]

DOE Optimization and Phase Morphology of Electrospun Nanofibers of PANI/PMMA Blends

Desai K., Sung C., University of Massachusetts-Lowell, US

Electrospinning is a process by which sub-micron polymer fibers can be produced using an electrostatically driven jet of polymer solution. The fibers are collected as a non-woven mat or membrane with high surface area to [...]
