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 [...]

Rapid Fabrication of Nanofibrous Membranes inside microchannels using Femtosecond Laser Micromaching

Tavangar A., Tan B., Venkatakrishnan K., Ryerson University, CA

In this paper, we propose a single-step technique to develop membrane-based microfluidic channels using femtosecond laser micromachining. The proposed method fabricates both the nanoporous membrane and microfluidic channel in a single step under ambient condition. [...]

Electrospun TiO2 Fibers as a Material for Dye Sensitizied Solar Cells

Duchoslav J., Rubáek L., Kavan L., Zukalová M., Procházka J., Elmarco Ltd., CZ

Electrospinning is a method for producing polymeric fabric with fibers ranging from 50 to 500 nm in diameter. It has been demonstrated that fibrous structure is preserved even after annealing when precursor of inorganic compound [...]

Preparation and characterization of highly porous PVDF nanofibers and yarns

Andrukh T., Few C., Burtovyy O., Burtovyy R., Burtovyy O., Burtovyy R., Luzinov I., Kornev K., Clemson University, US

Unique highly porous Polyvinylidene difluoride (PVDF) nanofibers (Figure 1) of about 50-500 nm in diameter were prepared by electrospinning. Electrospinning setup (Figure 2) allows us to control the nanofiber placement on the gap-type electrodes. In [...]

The effect of polymerization rate on the formation of polyaniline nanofibers

Huang Y-F, Lin C-W, National Yunlin University of Science and Technology, TW

This study reports the synthesis of polyaniline (PANI) nanofibers with an average diameter of 30~50 nm using HCl as a dopant. Experiments controlled the polymerization rate in terms of temperature and oxidant concentration. Transmission electron [...]

Biopolymerization-Driven Self-Assembly of Nanofiber Air-Bridges

Pabba S., Fasciotto B.H., Yazdanapanah M.M., Dobrokhotov V.V., Cohn R.W., University of Louisville, US

Many proteins polymerize in vivo to form nanometer diameter fibers, including actin and fibrin. In this study we consider the application of filament-forming proteins to nanostructure fabrication. Specifically, protein fibers are induced to polymerize and [...]

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 [...]
