A novel hybrid lithium-ion anode material based on coaxially coated Si shells on carbon nanofibers (CNF). The unique cup-stacking graphitic microstructure makes the CNFs an effective Liintercalation medium. Highly reversible Liintercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. Addition of surface effect dominant sites in close proximity to the intercalation medium results in a hybrid device that includes advantages of both batteries and capacitors.

Energy storage devices including stabilized silicon

An electrochemical method for measuring the activity of enzymes using nanoelectrode arrays fabricated with vertically aligned carbon nanofibers. Short peptide substrates specific to disease-related enzymes are covalently attached to the exposed nanofiber tips. A redox moiety, such as ferrocene, can be linked at the distal end of the nanofibers. Contact of the arrays with a biological sample containing one or more target enzymes results in cleavage of the peptides and changes the redox signal of the redox moiety indicating the presence of the target enzymes.

Electrochemical detection of proteases using AC voltammetry on nanoelectrode arrays

A novel hybrid lithium-ion anode material based on coaxially coated Si shells on vertically aligned carbon nanofiber (CNF) arrays. The unique cup-stacking graphitic microstructure makes the bare vertically aligned CNF array an effective Liintercalation medium. Highly reversible Liintercalation and extraction were observed at high power rates. More importantly, the highly conductive and mechanically stable CNF core optionally supports a coaxially coated amorphous Si shell which has much higher theoretical specific capacity by forming fully lithiated alloy. The broken graphitic edges at the CNF sidewall ensure good electrical connection with the Si shell during charge/discharge processes.
