[nanoRequest] Copper ink for inkjet printing process
A French company are seeking copper ink for inkjet printing process.

[nanoRequest] monitoring air pollution using nanosensors
The Pollutants in the air can be analysed/moniotored by passing it through nanosensors,thus finding the amount/properties of the polluted air.

[nanoRequest] Formula for shielding the field from a permanent magnet
I'm working on a formula for shielding the field from a permanent magnet. The formula calls for silver coated magnetic (iron oxide) microspheres having particle sizes of 5 to 75 microns in diameter with a mean particle size of about 45 microns, and typical silver thickness of 500 angstroms. It does not indicate whether to use solid or hollow microspheres however.

[nanoRequest] Alternative routes to lowering interfacial tension
We are a large multinational consumer goods company, seeking novel materials / technologies and/or new mechanisms that deliver low interfacial tension. Consumer products such as laundry detergents contain large amounts of surfactants (up to 40% by weight of the formulation). Their primary role is to aid cleaning by reducing the interfacial energy between the dirt / soil and the wash solution. This is achieved by adsorption of material at or across the interface. We now want to identify alternatives that are more weight-efficient than the current surfactant technologies.
