Boron doped diamond microelectrodes arrays for electrochemical detection in HPLC

Boron-doped diamond microelectrodes for use in capillary electrophoresis with electrochemical detection.

The fabrication and characterization of boron-doped diamond microelectrodes for use in electrochemical detection coupled with capillary electrophoresis (CE-EC) is discussed. The microelectrodes were prepared by coating thin films of polycrystalline diamond on electrochemically sharpened platinum wires (76-, 25-, and 10-microm diameter), using microwave-assisted chemical vapor deposition (CVD). ...

Determination of Clinically Relevant Compounds using HPLC and Electrochemical Detection with a Boron-Doped Diamond Electrode

Boron-doped diamond nanograss array for electrochemical sensors.

A novel BDD nanograss array has been prepared simply on a heavily doped BDD film by reactive ion etching for use as an electrochemical sensor, which improved the reactive site, promoted the electrocatalytic activity, accelerated the electron transfer, and enhanced the selectivity.

Boron-doped diamond nano/microelectrodes for biosensing and in vitro measurements.

Since the fabrication of the first diamond electrode in the mid 1980s, repid progress has been made on the development and application of this new type of electrode material. Boron-doped diamond (BDD) electrodes exhibit outstanding properties compared to oxygen-containing sp2 carbon electrodes. These properties make BDD electrodes an ideal choice for use in complex samples. In recent years, BDD...

Superconductivity in boron-doped diamond.

Superconductivity of boron-doped diamond, reported recently at T(c)=4 K, is investigated exploiting its electronic and vibrational analogies to MgB2. The deformation potential of the hole states arising from the C-C bond-stretch mode is 60% larger than the corresponding quantity in MgB2 that drives its high T(c), leading to very large electron-phonon matrix elements. The calculated coupling str...
