Colloid and polymer science, rheology and electrorheology, complex fluids, molecular thermodynamics, transport phenomena, molecular simulation. The interesting and technologically useful properties of modern, high performance materials are a direct result of nanoscale and/or molecular control of their underlying microstructure. Intelligent materials processing strategies control this microstructure to achieve a desired molecular and often, supramolecular structure to meet specific product performance criteria. Thus, our research is focused on developing a fundamental understanding of the dynamical behavior of materials during processing, which can be used to predict the effects of processing on material microstructure and hence, final product performance. This research has broad application and is supported by numerous international industrial concerns as well as by the National Science Foundation. Much of the research is collaborative with investigators and institutions from around the world.

Research in the Bloch group involves the synthesis and characterization of porous materials as novel adsorbents and catalysts. In order to address problems with the storage and/or activation of natural gas we are targeting the synthesis of metal-organic polyhedra based solids and liquids. In the case of the former, the modular synthesis of discrete clusters allows for precise tuning of pore size and geometry to optimize solid-gas interactions. Towards porous liquids, both neutral and charged polyhedra bearing various surface ligand functional groups are being prepared as a means to tune melting point, solubility, and gas uptake in these unique materials. In addition to a host of spectroscopic techniques, our lab utilizes single-crystal and powder X-ray and neutron diffraction, small angle scattering, and inelastic neutron scattering.

The primary focus of the Epps laboratory lies in designing, building, and characterizing new polymeric materials exhibiting molecular level self-assembly. Several applications for block copolymers and polymer blends under investigation in our group include: battery and fuel cell membranes, organic photovoltaics, analytical separations membranes, nanoscale containers and scaffolds for targeted drug delivery, precursors to electronic arrays, and surface responsive materials. We manipulate polymer internal and external interfacial characteristics in bulk and thin film environments to influence the ordering and stability of polymer structures. Assembly processes in our materials are explored with a comprehensive array of reciprocal space (small and wide-angle x-ray and neutron scattering), real space (optical, scanning probe, and electron microscopy), mechanical (dynamic mechanical analysis), and spectroscopic (x-ray photoelectron spectroscopy, near-edge x-ray absorption fine structure, and infrared spectroscopy) techniques. Researchers in the group gain experience in chemistry, chemical engineering, materials science, and biology.

Our group is interested in several polymer-based research areas, including (i) stimuli-responsive materials, (ii) novel photopolymerization and photocoupling reactions for surface engineering and photolithography, (iii) DNA recognition and assembly using ‘click’ nucleic acids, and (iv) utilizing the coiled-coil motif to guide biomolecular self-assembly. Our general research approach is to design and synthesize materials from the monomer up to precisely tune the macromolecular architecture. We then utilize an array of characterization techniques, such as rheometry, scattering, and microscopy, to better understand the relationship between the underlying microscopic structure and the macroscopic property. This latter process informs the direction for monomer design and synthesis to optimize the desired property for a specific application.

The main goal of our research is to analyze, control and exploit molecular interactions involving proteins and colloidal particles. The motivation is initially to obtain improved quantitative insights into existing processes, leading to more effective methods for designing and using them, but an auxiliary objective is to develop new products and operations. These themes bring together a diverse collection of research activities, discussed below, involving theoretical and experimental work dealing with both the fundamentals — transport, kinetic and thermodynamic phenomena — and their interaction in the process environment. The path from molecular structure through continuum properties to process design represents the central paradigm in modern chemical engineering, but it has been applied much less extensively to species such as proteins than to small molecules; such processes as protein separations still depend very heavily on empirical methods for design and optimization.

Maximizing and controlling protein stability is a ubiquitous problem in biotechnology applications from protein expression to biopharmaceutical production. Marginally stable or unstable proteins lead to loss of catalytic enzymatic activity, loss of protein drug potency, and possibly to immunogenic responses in patients. Our laboratory focuses on problems ranging from thermodynamics of protein folding, to structural and mechanistic features of protein unfolding and aggregation, to protein-protein interactions and aggregate phase behavior, to molecular modeling of protein-protein interactions and protein folding. We combine experiment, theory, and engineering models to develop fundamental yet practical approaches to predicting and interpreting the behavior of a variety of commercial and model protein systems.
