Plasma-Treated and Collagen-Coated PLLA Nanofiber Membrane for Cartilage Tissue Engineering

Chen J.P., Lee S.F., Chiang I.P., Chang Gung University, TW

Biodegradable nanofiber membranes from poly-L-lactic acid (PLLA) were prepared by electrospinning to be used as a scaffold in cartilage tissue engineering. Parameters during the electrospinning process were studied in detail in terms of diameters of [...]

Coating Growth on Nanofibers: Multi-Scale Modeling, Simulations and Experiments

Buldum A., Clemons C., Evans E.A., Kreider K.L., Young G.W., The University of Akron, US

Theoretical and experimental investigations on nanoscale deposition technology are critical for nanoscale materials research and for future nanodevice applications. Moreover, because of the varied and coupled physical phenomena involved (mechanical, electromagnetic, chemical, thermal, etc.), the [...]

Electron Sources for Massively Parallel Electron Beam Lithography System using Single Vertically Aligned Carbon Nanofiber Cathodes

Guillorn M.A., Whealton J.H., Baylor L.R., Melechko A.V, Merkulov V.I., Hensley D.K., Hale M.D., Kasica R.J., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

Electron beam lithography using a single beam cannot achieve acceptable throughput levels to become a viable manufacturing technology. The digital electrostatic e-beam array lithography (DEAL) concept under development at the Oak Ridge National Laboratory proposes [...]

Nanoelectronic Devices Constructed Using Individual Vertically Aligned Carbon Nanofibers

Yang X., Austin D.W., Guillorn M.A., Merkulov V.I., Melechko A.V, Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

We are fabricating active nanoscale electronic devices based on Vertically Aligned Carbon Nanofibers (VACNF). VACNFs are synthesized in a high-density Plasma-Enhanced Chemical Vapor Deposition (PECVD) process that provides a high degree of control of the [...]

Electrical Characterization of Polyaniline/Polyethylene Oxide Nanofibers for Field Effect Transistors

Mueller C.H., Theofylaktos N., Pinto N.J., Robinson D.C., Miranda F.A., Analex Corporation, US

Nanofibers comprised of copolymer polyaniline/polyethylene blends are being investigated for use in nanoelectronic applications such as field effect transistors and ultra-small antennas. The nanofibers were fabricated by an electrospinning technique, wherein a high voltage (typically [...]

Carbon Nanofiber-Based Electrode Interface to Microbial Biofilms

McKnight T.E., Melechko A.V, Guillorn M.A., Merkulov V.I., Fleming J.T., Hensley D.K., Hullander E., McPherson J., Nivens D., Sayler G.S., Lowndes D.H., Simpson M.L., Oak Ridge National Laboratory, US

We report on the integration of bacterial biofilms with carbon nanofiber-based electrochemical systems to provide a robust biosensor platform. Biofilms are robust, self-packaged communities of whole cells that have attracted much attention due to their [...]

A Novel Polymer Nanofiber Interface for Chemical and Biochemical Sensor Applications

Kwoun S.J., Lee R.M., Han B., Ko F.K., Drexel University, US

Polymer thin films are used extensively as a chemically sensing medium in variety types of acoustic sensors. It is well known that the sensitivity of a sensing film is proportional to the surface area of [...]
