Abstract:
There are disclosed a polyelectrolyte membrane comprising at least one syndiotactic styrenic polymer or copolymer in its clathrate form, and having ion-exchange groups, methods for its productions and a fuel cell comprising said polyelectrolyte membrane. Preferably, the syndiotactic styrenic polymer or copolymer in its clathrate form is syndiotactic polystyrene. The polyelectrolyte membrane according to the invention shows good electric conductivity as well as good mechanical properties and it can be suitably used for fuel cells and similar electrochemical applications.
Abstract:
The present invention relates to a method for manufacturing a single electron device (80) by electro-migration of nanoclusters (52). The inventive method comprises the steps of:
patterning a substrate (10, 40); preparing metallic passivated nanoclusters (52); forcing the metallic passivated nanoclusters (52) to assembly over the patterned substrate (10) under control of a non homogeneous electric field.
The invention also relates to a single electron device comprising a quantum dot as single electron component.
