... the scanning ion-conductance microscope(SICM)... scans a sample not with a metal or diamond tip but with a glass micropipette containing a tiny electrode. The workers immerse the sample and the pipette in a bath of electrolyte(such as a salt solution) and establish a voltage difference between the electrode within the pipette and another electrode in the bath. A current of ions tends to flow between the electrodes by way of the pipette opening, but when the pipette approaches the surface of the sample, the current weakens. It disappears altogether when the scanned pipette touches the sample, which blocks the opening. Equipped with a feedback mechanism that maintains a constant ion current through the pipette opening, the SICM can profile a sample's topography. The fineness of the pipette does limit the SICM's resolution to about. 2 micron(10 nanometers may eventually be feasible).

OBS

The device is therefore best suited to more specialized functions - studying a living cell’s electrical behavior, for example. When a cell is stimulated, so-called ion channels in its membrane open and close, allowing tiny currents of ions to pass. Hansma hopes to detect individual ion channels and study their behavior once the SICM’s resolution has been improved.

English

Subject field(s)
  • Water Pollution
  • Surface Treatment of Metals
CONT

The Keronite coating process resembles anodising in that it uses an electric power supply and an electrolyte bath. However, it is significantly different from anodising in that it produces much harder, thicker layers while using environmentally less harmful alkali electrolytes and a specially modulated AC voltage. Keronite coating involves creating a plasma discharge around a component immersed in an electrolyte that provides surface oxidation as well as the potential for elemental co-deposition.

OBS

Keronite is a trade mark of the society Keronite ltd.

French

Domaine(s)
  • Pollution de l'eau
  • Traitements de surface des métaux
CONT

Le procédé Keronite, appelé oxydation électrolytique à décharge de plasma, produit un revêtement céramique extrêmement dur qui protège de la corrosion les métaux tels que l'aluminium, le magnésium et le titane.

OBS

Keronite est une marque déposée de la société Keronite ltd.
