Topological insulators, which were first introduced at Penn, are new materials with novel features such as protected states that hold potential for quantum computing.

We are often taught that the difference between solids and liquids is that in solids, each of the constituent particles has a well-defined average position while in liquids, particles are constantly rearranging and changing their neighbors.
Microcapsules that encapsulate and protect molecules and materials by forming isolated aqueous compartments inside hollow shells are widely used in a variety of applications in the food, pharmaceutical, cosmetics, and agriculture industries.
Janus colloids are composed of two-faced particles with distinctive surfaces and/or compartments. Lee, Collings, & Yodh have created the first Janus particles with a liquid crystal (LC) compartment. The droplets were prepared by combining microfluidic and phase separation techniques, and the LC compartment morphologies can be easily controlled to realize unique confining geometries (Fig.
Synthetic methods produce colloidal nanocrystals that are metallic, semiconducting, and insulating. These nanocrystals have been typically used to form only a single component in devices. IRG-4 has exploited the library of colloidal nanocrystals and designed the materials, surfaces, and interfaces to construct all the components of field-effect transistors.
