Low-voltage electroosmotic pumps fabricated from track-etched polymer membranes.
Track-etched polymer membranes are used to realize low-voltage electroosmotic (EO) pumps. The nanopores in polycarbonate (PC) and polyethylene terephthalate (PET) membranes were fabricated by the track-etching technique, the pore diameter was controlled in the range of 100 to 250 nm by adjusting the etching time. The results show that these EO pumps can provide high flow rates at low applied vo...
متن کاملCyclic-voltammetry study of bismuth telluride electrodeposition in polycarbonate etched ion-track membranes
Bismuth telluride compounds are well-known to be among the most efficient thermoelectric materials at room temperature. Currently, some efforts are made to synthesize nanowires, since theoretical predictions have shown that their transport properties can be favourably modified compared with bulk materials. The feasibility of the electrochemical synthesis of bismuth telluride nanowires in porous...
متن کاملVesicle extrusion through polycarbonate track-etched membranes using a hand-held mini-extruder.
The vesicle extrusion method is used for preparing small (e.g., 100 nm diameter) monodisperse (uniform-sized) vesicles. Polycarbonate track-etched membranes with pores generally ranging from 50 to 200 nm in diameter and a hand-held mini-extruder are used for such a procedure. Extrusion through small (100 nm in diameter or smaller) pores also ensures that the vesicle population is predominantly ...
متن کاملCyclic voltammetry on recessed nanodisk-array electrodes prepared from track-etched polycarbonate membranes with 10-nm diameter pores.
This paper described cyclic voltammograms (CVs) on a recessed nanodisk-array electrode (RNE) prepared from a track-etched polycarbonate membrane (TEPCM) with 10-nm diameter pores. A RNE was prepared via sputtering of a gold thin film onto a TEPCM whose pores were coated with polyvinylpyrrolidone. CVs of such a RNE changed from peak-shaped to sigmoidal with decreasing scan rate due to the transi...
متن کاملSelf-supported particle-track-etched polycarbonate membranes as templates for cylindrical polypyrrole nanotubes and nanowires: an X-ray scattering and scanning force microscopy investigation.
Self-supported particle-track-etched polycarbonate membranes with nearly perfect cylindrical pores are used for the preparation of similarly perfect cylindrical polypyrrole nanowires and nanotubes. A complete investigation of the structural properties that result at different stages of the preparation route of polypyrrole nanowires and nanotubes is based on a combination of real and reciprocal ...
