Electrospun Nanofiber Membranes and Electrodes for Fuel Cells

Wycisk R., Ballengee J., Park J.W., Brodt M., Pintauro P.N., Vanderbilt University, US

The focus of our research group has been on the use of electrospinning for the fabrication of nanofiber membranes and electrodes for PEM fuel cells. We have demonstrated dramatic improvement in fuel cell performance and [...]

1D Multi-Structured Micro/nanomaterials with Special Wettability

Zhao Y., Beihang University, CN

With the progresses in material sciences, the generation of microscopic materials experiences an architectural evolution process from simple to complex. The complex interior structures will enable such materials a number of potential applications. Here we [...]

Structural characterization and photocatalytic activity of electrospun TiO2 and Ce-doped TiO2 nanofibers

Sang-urai S., Worayingyong A., Mansiri S., Smith M.F., Seraphin S., Kasetsart University, TH

Mixed phase TiO2 and Ce-doped TiO2 nanofibers with different content (0.5, 2.0, 8.0%) ofcerium ions were prepared by a sol-gel electro-spinning method. Results from SEM showed nobeads on the undoped-TiO2 and Ce-doped TiO2 nanofibers with [...]

Synthesis of Magnetically Sensitive Nanomaterials with Tunable Properties

Ieta A., Patus J., Apenowic J., Marius C., State University of New York at Oswego, US

New magnetic nanomaterials with tunable properties were produced using three procedures. (1) Mixtures of polyvinyl alcohol (PVA) solutions and ferric oxide [3] based ferrofluid were prepared and also electrospun with the purpose of synthesizing magnetic [...]

Hollow core-shell structured mesoporous MWCNT/carbon nanofiber composites by electrospinning and silica template as counter electrodes for dye-sensitized solar cells

Park S.H., Kim B-K., Lee W.-J., Chonnam National University, KR

The multi-walled carbon nanotube (CNT)-embedded carbon nanofibers with hollow core/highly mesoporous shell stucture (CNT/Meso-HACNF) are prepared by concentric electrospinning using poly(methyl methacrylate) (PMMA) as a pyrolytic core precursor with either CNT/polyacrylonitrile (PAN) or fumed silica [...]

Electrospun 5-fluorouracil loaded bovine serum albumin-polyvinylpyrrolidone nanofibers

Illangakoon U.E., Chatterton N.P., Williams G.R., Nazir T., London Metropolitan University, UK

5-FU loaded bovine serum albumin (BSA)/ polyvinylpyrrolidone (PVP) nanofibers prepared using an electrospinning process. The nanofibers were characterised by scanning electron microscopy (SEM) energy - dispersion spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction [...]

Electrospun Nanofibrous Scaffold for Controll Drug Delivery

Leung V., Hartwell R., Faure E., Yang H., Ghahary A., Ko F., University of British Columbia, CA

This study aims to design methods for controlling drug release from polymer nanofibres, and use these methods as a guide for designing nanofibre wound dressings with customizable release profile for a range of drugs. The [...]

Multifunctional Micropatterned Nanofiber Capable of Cell Patterning, Metabolite Detection, and Growth Factor Delivery

Koh W.G., Lee H.J., Lee H.W., Lee H.J., Lee H.W., Park S., Yonsei University, KR

This study describes the development of multifunctional nanofiber scaffolds consisting of multiple layers of nanofiber scaffolds and nanofiber-incorporated PEG hydrogels. We fabricated double-layered nanofiber scaffolds that were micropatterned with PEG hydrogels by combining two-step sequential [...]

Flexible Organic-Inorganic Core-Shell Nanofibers by Electrospinning and Atomic Layer Deposition

Kayaci F., Ozgit-Akgun C., Donmez I., Biyikli N., Uyar T., Bilkent University, TR

We report on the fabrication of organic-inorganic core-shell nanofibers by using two-step approach; electrospinning and atomic layer deposition (ALD). In the first step, nylon (polymeric organic core) nanofibers having different average fiber diameters were electrospun [...]

Electrospun Carbon nanofibers-Based Supercapacitors

Zhou Z.P., North Dakota State University, US

For efficient use of conductive polymers, such as Polyaniline (PANI) and Polypyrrole (PPy), in pseudocapacitors and other electrochemical applications, the poor conductivity of the conductive polymers is a major problem. To solve the problem, here [...]
