Daniel, Susan

Research Interests:  In the Daniel Research Group we investigate how the chemical, physical, and organizational properties of molecules at a surface impact the interactions of the interface with other materials and the dynamic phenomena that result from those interactions. We study phenomena at both biological interfaces and chemically patterned surfaces that interact with soft matter – liquids; polymers; and biological materials, like cells, viruses, proteins, and lipids. In the context of energy and sustainability, we strive to design interfaces that reduce the costs of creating energy and transporting it. Towards this end we have created surfaces that use surface tension forces to remove liquid condensate from heat exchanger surfaces, greatly enhancing heat transfer coefficients. On the biointerface side, we have worked on understanding the characteristics of algae cell surfaces that lead to tunable aggregation for the efficient processing of biofuel extraction.

Hanrath, Tobias

Research Interests: There is a tremendous opportunity space for nanostructured materials to play a key role in next generation energy technologies. Our research efforts focus on the fundamental study of optoelectronic properties of semiconductor nanocrystals; this work is inspired by the potential application of these materials in solar energy conversion and energy storage devices. The semiconductor nanocrystals used in our work provide a diverse set of building blocks whose electronic and optical properties differ from their bulk counterparts due to the spatial wavefunction confinement. This quantum confinement effect allows us to engineer the materials properties through simple adjustments in nanocrystal size, shape, composition, and surface chemistry. In addition to their immense potential for technological applications, these materials also provide a material system to experimentally test fundamental quantum mechanical concepts.

Joo, Yong

Research Interests:  Our research focuses on the integration of continuum analysis with molecular details in polymeric materials processing. Areas of current interests include the microstructural rheology and processing of complex fluids, the formation of nanofibers via electrospinning, and the occurrence of viscoelastic instabilities in polymer flows. In particular, we have laid the foundation for new experimental and theoretical studies on nanofiber formation via electrospinning. The resulting nanofibers are collected as non-woven mats with large surface area to volume ratios which can be used in filtration, catalysis, membrane applications and reinforced composites. We develope comprehensive models to provide a fundamental understanding of nanofiber formation and we investigate the material-processing-structure relationship in nanoscale fibers. Nanofibers with controlled nano/microstructures are also being utilized in various fundamental studies such as hydrogen production via alkaline hydrolysis of cellulose.

Tester, Jeff

Director of the Cornell Energy Institute and
Associate Director for Energy in the Atkinson Center for a Sustainable Future.

Research Interests: Geothermal energy and biomass-based fuels are the focus of Jeff Tester’s research. In the geothermal area, his research group is evaluating the performance of Enhanced Geothermal Systems (EGS) and geothermal heat pumps with specific projects on advanced drilling methods, regional assessment of low enthalpy geothermal resources, thermal hydraulic and system modeling of fractured geothermal reservoirs for power, district heating and co-generation applications, and evaluations of heat pumps for cooling applications in cell towers and data centers.  In the bioenergy area, integrated life cycle assessment and techno-economic models of biomass systems are being developed along with experimentally probing of kinetics, phase behavior and transport phenomena in hydrothermal and supercritical media at elevated temperatures and pressures for applications in the conversion and upgrading of a range of biomass feedstocks  from high lipid algae and food processing wastes to lignin cellulosic residuals and agricultural wastes.

Zia, Roseanna

Research Interests: In the Zia Research Group our goal is to understand and elucidate the micro-mechancical underpinnings of macroscopic material behaviors in complex fluids and other soft matter, with a focus on non-equilibrium systems. Problems of interest include the storage of the microstructural entropy that underlies mechanical stress, the imbalance between fluctuation and dissipation driven by stress gradients, and the structural coarsening that enables sudden collapse of dynamically arrested gels, to name a few. From this understanding we work out new theories to predict macroscopic behaviors from the detailed evolution of particle microstructure. We have a dual aim: first, to discover fundamental mechanisms that may lead to entirely new understanding of non-equilibrium dynamics in complex media; and second, to apply our theory to advanced technologies ranging from disease treatment to smart materials.
