Functional Nanostructures Based On Polymeric Templates @ University of Massachusetts Amherst
ABSTRACT Proposal No: 9871782 Proposal Type: Nanotechnology Initiative Principal Investigator: Mark T. Tuominen Affiliation: University of Massachusetts at Amherst This grant is awarded through the Separations and Purification Processes Program of the Division of Chemical and Transport Systems. It is jointly funded through the Division of Chemical and Transport Systems, the Division of Design Manufacturing and Industrial Innovation, and the Division of Materials Research. The research will seek to develop simple, robust routes to generate functional nanoscopic structures utilizing thin films of block copolymers as templates. A key element in the proposed research is the ability to remove one of the blocks in an easy and quantitative manner to generate a porous structure with well-defined pore size and shape. The project combines polymer chemistry and chemicals processing with the physics of ultra small scale devices to produce functional nanostructures. A range of potential applications exist for these materials, including membranes with well defined nanopores, quantum wires with giant magnetoresistance, and organized quantum dot structures.

Acquisition of An Analytical Ultracentrifuge and a High Temperature Gel Permeation Chromatograph For Research and Education in Polymer Science and Engineering @ University of Massachusetts Amherst
9975762 Penelle
This award will provide partial support for the acquisition of two analytical instruments, a high-temperature GPC (gel permeation chromatography) and an analytical ultracentrifuge. These instruments will be added to a newly created 'molecular weight characterization' facility hosted by the Department of Polymer Science and Engineering at Univeristy of Massachussetts, Amherst, and will allow them to determine molecular weights even for "problem" polymers such as self-associating polymers, polymers poorly soluble under classical conditions (i.e., in an organic solvent at room temperature) and water-soluble polymers. The co-PIs (four main users and three minor users) have research projects in the field of polymer synthesis, biomaterials, and polymer characterization that are summarized in the research section and will strongly benefit from a direct access to these instruments.
The new facility is administered under the same rules as the current Materials Research Science and Engineering Center - Polymer Science & Engineering facilities, with full access to the about twenty-five research groups at the University of Massachusetts with research interests in the field of polymeric materials (Departments of Polymer Science and Engineering, Chemistry, Physics, and Chemical Engineering). Access to the ultracentrifuge will also be provided to researchers in the Molecular Biology program. Both instruments will contribute to the success of research programs at other places in the country, in particular at Howard University via the participation of one of the minor users.
The equipment will be integrated into the educational programs of students at all levels (i.e., graduate and undergraduate, high school outreach, and K-12 programs). The instruments will also be used in the U. of Massachusetts Materials Research Science and Engineering Center supported workshops, where K-12 teachers learn how to introduce polymer science and engineering concepts into their classroom curricula. %%% The instrumentation will be used for polymer science and engineering research and educational activities at University of Massachusetts and Howard University. ***

Nanoscale Interdisciplinary Research Teams (Nirt): Copolymer Templates - a Self-Assembling Route to High-Density Arrays of Functional Nanostructures @ University of Massachusetts Amherst
This Nanoscale Interdisciplinary Research Teams (NIRT) project it to develop robust routes to produce high-density arrays of functional nanoscopic structures using nanoporous templates derived from diblock copolymer thin films. The diblock copolymer films used possess self-assembled cylindrical microdomains oriented normal to the surface of the film, with cylinder densities in excess of 1.0 x 10^12 /in^2. Selective degradation of the minor polymer block and cross-linking of the major block results in a polymer film having a high-density array of nanopores that serves as a template for the fabrication of functional arrays of nanoscopic structures. The project will expand the potential of this simple process by developing methods that give pore diameters ranging from the nanometer to the hundreds of nanometers. The research will advance the use of these templates to produce functional arrays of nanoscopic structures. This includes the use of metal electrodeposition in the template pores to produce ultrahigh-density arrays of magnetic nanowires for magnetic storage applications. The nanopore array can be patterned laterally using electron-beam lithography, to create magnetic nanowires and nanoparticle electron-transport studies. The nanoporous arrays will also be used as electrochemical nanoelectrode arrays, as reactive-ion-etching masks for silicon technology, and to produce glass nanopillars.
The project provides several unique educational opportunities including REU, RET, an interdepartmental nanoscience course, biweekly interdisciplinary meetings, and a technology-training program based on interactive digital video. This project integrates efforts from the academic and industrial sectors, with collaborations from national laboratories and international groups.
