Overview

Activities in the Department span a wide range of topics from soft, composite and hard materials to energy research, nanoscience, and biological systems. A UNIFYING THEME is the STUDY OF MATERIAL FUNCTIONALITY AND ITS RELATION TO FUNDAMENTAL PROPERTIES AT MULTIPLE SCALES. These properties may be mechanical, structural, chemical, electronic, magnetic, optical, and more. Some examples are:
How do shapes and sizes of nm-sized particles affect their properties?

How can we tune the properties of solar cells by manipulating their material interfaces?

How does friction in knee and hip joints depend on polyelectrolytes that lubricate them?

How can we design self-assembling, even self-replicating (bio)chemical systems?

THE RESEARCH IS BASED ON AN INTERDISCIPLINARY APPROACH, and indeed the scientists bring complementary experience in chemistry, physics, and biophysics, including theory and experiment.

    Our group's research is focused on understanding unique properties and behavior of materials and interfaces, using first principles quantum mechanical calculations based mostly on density functional theory and many-body perturbation theory. The group is actively engaged in prediction and interpretation of novel experiments, as well as in the development of formalism and methodology.

    Our research is focused on correlating structure and function in energy storage and conversion materials by advanced magnetic resonance methods. We aim to understand how the composition of materials affects their functionality and how we can control their functionality through deviation from ideal stoichiometry. In particular we are interested in materials for energy storage, such as Li and Na ion batteries, and in the role interfacial chemistry plays in the functionality of electrode and electrolyte materials. We use a wide range of magnetic resonance techniques: solid state NMR, Electron Paramagnetic Resonance (EPR) and Dynamic Nuclear Polarization (DNP). Additionally we investigate the process of polarization transfer from electron spins to nuclear spins in solids DNP utilizing external and internal polarization agents.
