Harnessing Materials for Energy

Harnessing Quantum Interference in Molecular Dielectric Materials.

We investigate the relationship between dielectric response and charge transport in molecule-based materials operating in the quantum coherent regime. We find that quantum interference affects these observables differently, for instance, allowing current passing through certain materials to be reduced by orders of magnitude without affecting dielectric behavior (or band gap). As an example, we ...

Harnessing the Bethe free energy†

A wide class of problems in combinatorics, computer science and physics can be described along the following lines. There are a large number of variables ranging over a finite domain that interact through constraints that each bind a few variables and either encourage or discourage certain value combinations. Examples include the k-SAT problem or the Ising model. Such models naturally induce a ...

Materials for sustainable energy.

Materials for solar fuels and chemicals Joseph H. Montoya, Linsey C. Seitz, Pongkarn Chakthranont, Aleksandra Vojvodic, Thomas F. Jaramillo and Jens K. Nørskov 70 Available and affordable energy has so far led to spectacular industrialization and development, but with growth accelerating in developing countries, demands on non-renewable energy sources are reaching their limits. Moreover, the re...
