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

, , , , , , , ,
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 [...]

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

, , , ,
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 [...]

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

, , , , , , , , , ,
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 [...]
