Welcome to the Dobbins Laboratory at Rowan University

My research program focuses on gaining a fundamental understanding of the relationship between structure (at the atomic, nano-, and micro- levels) and dynamics (e.g. electron and phonon excitations, diffusion, and reaction kinetics) in composite materials. Properties of interest include surface adsorption, short range hopping dynamics, and long range diffusional transport. We use neutron and X-ray scattering as primary tools for gaining materials insights.

Hydrogen for Fuel Cells from NanoMushrooms Made of NaAlH4

Hydrides are used to deliver hydrogen for fuel cells for automotive applications. The shape (or morphology of those hydrides) determine the speed of hydrogen gas delivery (or kinetics). Nanostructuring is a key strategy in improving speed of hydrogen desorption reaction. Study of those nanostructures is made possible by synchrotron x-ray scattering performed at the Advanced Photon Source. X-rays are used to determine shape and size of nanoconfined hydrides by measuring mass fractal dimension (D). Initially, NaAlH4 powders are surface fractals. After infiltration into porous alumina, these powders are mass fractals.
