Clathrate materials present a novel class of storage media for hydrogen. These unusual crystalline solids are comprised of a lattice of polyhedral cavities that can trap a range of different guest molecules, including hydrogen.

We have demonstrated the first ever hybrid polymer film of an insoluble polymer with an acid (top picture).
Graduate student Mingjing Ha working with Optomec, Inc. and Northwestern University collaborators (Mark Hersam) has demonstrated low voltage, fast carbon nanotube (CNT) circuits printed on flexible plastic substrates. The circuits are fabricated by aerosol jet printing from a liquid dielectric ink (ion gel) and a purified semiconducting CNT ink (Northwestern).
Our team has developed a simple solution-based method to fabricate arrays of ZnO nanowires inside of a glass microchannel.
Ordering of spherical particles represents a fundamental topic in materials science and engineering ranging from the sub-nanometer scale packing of atoms in simple crystals to micron sized assemblies of colloids.
