Fabrication and Electrochemical Property of Hybrid Carbon Nanofibers Based on Polyimide Precursor and Manganese Dioxide

Han N.K., Jeong Y.G., Chungnam National University, KR

Supercapacitors have recently received great interest from industry and academia as one of energy storage devices due to their high power density, fast charge time, and long cycle life. In this study, hybrid carbon nanofibers [...]

The Brain-Machine Interface: Nanotechniques for Improving Brain Electrochemical Monitoring and Modulating

Andrews R., Bennet K., Chang S.Y., Koehne J., Lee K., Meyyappan M., Rand E., NASA Ames Research Center, US

Purpose: Present-day neuromodulation, e.g. deep brain stimulation (DBS), is limited by inefficient charge transfer from electrodes to brain tissue, lack of brain chemical (neurotransmitter) monitoring, and absence of feedback-guided stimulation. Although DBS using platinum macroelectrodes [...]

Manganese Oxide/Carbon Nanofibers-Embedded Graphene Sheets for Capacitors

Ahn K-J, Yoon H., Chonnam National University, KR

We report the fabrication of a ternary nanoarchitecture consisting of manganese oxide (MnO), carbon nanofibers (CNFs), and reduced graphene oxide sheets and their application to supercapacitor electrodes. MnO nanoclusters-decorated CNFs (MCNFs) with diameters of about [...]

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 [...]

Cardiomyocyte Function on Poly-Lactic-co-Glycolic Acid: Carbon Nanofiber Composites under Electrical Stimulation

Stout D.A., Webster T.J., Brown Univeristy, US

In recent research, it was demonstrated that the use of nano-materials can promote the growth of cardiomyocytes when compared to the use of conventional or micro-structured materials. One such nano-material consisted of poly-lactic-co-glycolic acid (PLGA) [...]

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 [...]

Wu H.C., Li Y.Y., National Chung Cheng University, TW

In this manuscript, there are some significant results summarized as follows: 1. The platelet graphite nanofiners (PGNFs)were continuously produced by a vertical chemical vapor deposition reactor. 2. A detailed study found that the sulfur concentration [...]

Fabrication of poly(alizarin red)-carbon nanofibers composite film and its application as nitric oxide microsensor

Zheng D.Y., Hu C.G., Hu S.S., Hu C.G., Hu S.S., Wuhan University, CN

In this work, a poly(alizarin red) (PAR)-carbon nanofiber (CNFs) composite film was fabricated via a well-controlled in situ electro-polymerization method. This composite film exhibited good sensing and catalytic ability to the electrochemical oxidation of nitric [...]

Current-induced Breakdown of Carbon Nanofibers Under Vacuum and Atmospheric Conditions

Kitsuki H., Ngo Q., Suzuki M., Gleason K., Wilhite P., Cassell A.M., Moylan C.R., Li J., Yang C.Y., Santa Clara University, US

Current-induced breakdown phenomena of carbon nanofibers (CNFs) for the development of carbon-based interconnects are investigated to reveal current-carrying capacity and reliability of CNF devices. Scanning transmission electron microscopy (STEM) techniques are developed to study the [...]
