    摘要: Present invention involves a seal means suitable to replace the classic seals. For instance the seal means of present invention can be a liquid seal ring (7) to replace the classic rubber seal rings. Such is liquid O-ring can be adapted to resists the actuation pressure relying on surface tension forces. Such liquid O-rings can also be linked in series, hereby increasing the maximum seal pressure. In a preferred embodiment the seal means of present invention comprises two major components, a surface tension seal (7) and a pressure divider (4). The pressure divider will comprise a system that generates a pressure drop. Such pressure divider can be located before the surface tension seal and perform the first pressure drop. The combination of these two systems has the advantage that the surface tension seal is able to reduce the leakage to zero or essentially zero and that the pressure divider is able to perform a large pressure drop. Nevertheless, the surface tension seal can also create a considerable pressure drop. This means that in applications where the seal pressure of the surface tension seal is not exceeded, the pressure divider can be omitted. However, omitting the pressure divider will always result in tighter tolerances when manufacturing the seal.

    摘要: Disclosed are methods for fabricating pyrolysed carbon nanostructures. An example method includes providing a substrate, depositing a polymeric material, subjecting the polymeric material to a plasma etching process to form polymeric nanostructures, and pyrolysing the polymeric nanostructures to form carbon nanostructures. The polymeric material comprises either compounds with different plasma etch rates or compounds that can mask a plasma etching process. The plasma etching process may be an oxygen plasma etching process.
