Nanostructured Catalysts for Fuel Cells

Progress Report and Future Directions The fuel cell research cluster began with the DOE EPSCoR implementation grant “Fuel Cells: A Mobile Energy Source for the 21 Century” in July of 2001. The focus of this research was developing new and improved materials for hydrogen production and PEM fuel cells. Building on the major successes of this project, we proposed and were granted a renewed impleme...

The first bulk nanostructured metal

Nanotechnology has become an overused adjective, but there has been justified excitement in the context of structural materials. A class of iron alloys has been discovered in which a high density of strong interfaces can be created by heat-treatment alone. The packing of interfaces is so large, and the fact that there is an intrinsic work hardening mechanism in the structure, leads to remarkabl...

Thermal conductivity of bulk and monolayer MoS2

We show that the lattice contribution to the thermal conductivity of MoS2 strongly dominates the carrier contribution in a broad temperature range from 300 to 800K. Since theoretical insight into the lattice contribution is largely missing, though it would be essential for materials design, we solve the Boltzmann transport equation for the phonons self-consistently in order to evaluate the phon...

Nanostructured Catalysts in Activation of Light Alkanes

The activation of small alkane molecules originating from natural gas or renewable resources on metal oxide surfaces regains increasing scientific interest since direct utilization of saturated hydrocarbons will offer alternative pathways to higher value chemicals in a postpetroleum era. The focus of the project lies on oxidation catalysis of small alkane molecules including methane, ethane, pr...
