During the summer of 2001, our REU program expanded to 11 undergraduates, who as above, presented a seminar after completion of the research. The students, sponsors and projects are detailed below.

Lawrence Chiang (Northwestern University) worked with Strey, studying the interaction and packing of chiral molecules, specifically short fragment DNA spherulites, equilibrated in PEG, using the method of osmotic stress where cholesteric pitch was analyzed as a function of DNA interaxial distance and salt concentration.

Beth Cooper (Amherst High School) worked with Lesser, studying the molecular aspects of adhesion in crosslinked interfaces. The experimental program involved the synthesis of interfaces with controlled crosslinked densities using an epoxy based chemistry. Energies of adhesion (energy release rates) were measured using a double cantilever beam crack configuration.

Michal Ganz (Amherst High School) worked with Hsu, studying the crystallization behavior of poly(lactic acid) containing varying degrees of configurational defects, using Raman and infrared spectra.

Elizabeth Haley (Univ. of Massachusetts, Amherst) worked with Coughlin studying the copolymerization of styrene and methyl methacrylate with the ultimate goal of creating polymethylmethacrylate-polystyrene-poss( a cubic siloxane) hybrid organic-inorganic structures.

Linn Janski (Smith College) worked with Hoagland, studying the diffusion and electrophoreses of DNA on surfaces with introduced obstacles.

Jillian Marcus (Univ. of Massachusetts, Amherst) worked with Gido, measuring transport properties, namely, solubility, permeability, and diffusion of carbon dioxide and oxygen in a biodegradable, biosynthetic polyester material which is of interest in the food packaging industry.

Barbara Munoz (Oberlin College) worked with Emrick studying organic and polymeric aspects of nanoscopic semi-conducting particles known as "quantum dots". The project required the design of oligomers and polymers for attachment to the particle surface.

Jennifer Quansah (Mount Holyoke College) worked with Emrick on synthetic studies of new polymeric materials designed to be hydrophilic and biocompatible liquids. This involved significant efforts in monomer syntheses as well as characterization of the polymer products.

Sarah Rosenstein (Cornell University) worked with Russell characterizing thin film morphology of the styrene-butadiene-methyl methacrylate triblock copolymer using AFM. She also studied various casting solvents and annealing conditions as well as the selective etching of the microphase separated structures.

Diwakar Turaga (Univ. of Massachusetts, Amherst) worked with Muthukumar studying the conductivity of polyelectrolyte solutions. The measured frequency dependence of conductivity is qualitatively different from Kolrausch's law governing equivalent conductivity of such solutions.

Nicholas Wilson (Univ. of Massachusetts, Amherst) worked with Vining creating multimedia educational modules for various areas of chemistry including material science, molecular structure, and reaction kinetics.
