About About About
The Interfacial Design Laboratory is focused on developing and disseminating cutting edge research in the areas of renewable energy, electrochemistry, and corrosion prevention.  Our strategy is to develop and utilize novel characterization methods to clearly understand reasons of failure, inefficiency and poor performance. Using this foundation we then design rational solutions to challenges facing society.  The laboratory is led by Kevin N. Wood, Assistant Professor of Mechanical Engineering at San Diego State University.

Research


Batteries

Energy storage is the preeminent challenge facing the 21st century. Batteries are the key to enabling, potable power, electric vehicles, and a clean grid.

Fuel Cells

Fuel Cells are an essential part of the proposed hydrogen economy. The high efficiency of fuel cell devices make them a promising method for storing/generating energy.

Corrosion Prevention

Corrosion is a multi-billion dollar a year problem. Coatings and material modifications are essential for reducing waste and increasing productivity.

Interfacial Design

Interfacial design is a critical step in engineering solutions. To address these issues chemical and physical deposition strategies can be used.

Operando Characterization

Operando characterization platforms are an important method for determining the origins of failure and poor performance, enabling rational design strategies.
