6. Pulse-reversed electrodeposition with QCM monitoring to make magnetic nanowires in a nanotemplate
Cobalt nanowires with high perpendicular magnetic anisotropy are formed in a diblock copolymer film template using a pulse-reversed voltage with QCM monitoring. This in situ monitoring system along with the pulse-reversed field enables new control over the magnetic crystal growth.

3. Fabrication of a nanoporous template from a diblock copolymer film - neutral brush
A perpendicular orientation of cylindrical microdomains in diblock copolymer thin films is achieved by control over polymer-surface interactions. The block which forms cylindrical microdomains is removed by UV exposure and a chemical rinse to yield a nanoporous polymer film. The porous film can be used as a template for electrodeposition of metal nanodots or as a mask for reactive ion etching.

2. Fabrication of a nanoporous template from a diblock copolymer film - solvent annealing
An evaporation-induced flow in solvent cast block copolymer films can produce arrays of nanoscopic cylinders oriented normal to the surface and solvent annealing could markedly enhance the ordering of block copolymer microdomains in thin films. Without removing minor components, solvent-induced surface reconstruction can produce nanoporous structure in thin films. The porous film can be used as a template for deposition of quantum dots or as a mask for pattern transfer to the underneath substrates.

New Report from PEN: Nanotechnology Oversight

Written by J. Clarence Davies with a foreword by David Rejeski, this report provides a blueprint for federal nanotechnology oversight for the incoming administration. The report includes short- and longer-term agenda addressing Risk Research, Regulatory Coordination, Legislation, and Public Involvement.
