Self-assembly techniques are powerful and efficient methods for the synthesis of nanoscale materials. Using these techniques and their combination with other bottom-up fabrication processes, materials with hierarchical features can be produced with form and function in multiple length scales. We synthesize multifunctional nanoparticles through surfactant-assisted noncovalent interactions using nanoparticle building blocks. Self-assembly of these nano-building blocks results in functional materials that exhibit well-defined morphologies and hierarchical architectures for a wide range of applications. Hierarchically structured porphyrin nanocrystals can be synthesized through surfactant micelle-confined noncovalent interactions of photoactive porphyrins. We can amplify the intrinsic advantages of individual photoactive porphyrins by engineering them into well-defined active nanostructures. Through kinetic control, these nanocrystals exhibit precisely defined size, shape, and spatial arrangement of the individual porphyrins, which facilitates intermolecular mass and energy transfer. These self-assembly techniques provide remarkable flexibility to design morphologies and architectures that produce desirable properties for practical applications including photocatalysis, photodegradation, and phototherapy.

Political science undergraduate students often have a difficult time understanding the processes and methods of social science research. The foci of courses in comparative politics such as Latin American Politics or European Politics are typically descriptive information, concepts and theories, and an overview of the principal debates and research findings. This stands in sharp contrast to undergraduate pedagogy in the natural sciences, where laboratory sections supplement classroom activities. For example, biology students learn the basics of the discipline in the classroom, and simultaneously use the tools and methods of scientists in the lab to replicate elementary experiments. This multi-method approach not only reinforces the students' understanding of biological concepts, but also gives them an appreciation for how their professors spend their time and the challenges, pleasures, and limitations of academic research.
