Chemist Dr. Mary Elizabeth Anderson and her Hope College research group have developed a rapid and low energy process for the fabrication of these thermoelectric nanoparticles — a class of material with sustainable energy potential to capture waste heat and convert it into usable electricity.

With several Hope colleagues and collaborators at Michigan State, she published a 2017 paper in the journal Chemistry of Materials that details this new synthetic process. “It’s as good, if not better, than the conventional, typical methods. You can do mine in a day; it takes them weeks,” she reports, and adds, “the overall thermoelectric performance of our material is equivalent to or outperforms theirs.”

Anderson builds materials from the bottom up, assembling molecules and atoms into complex nanomaterials. The Hope students in her research group gain experience in the interdisciplinary field of nanoscience: the chemistry of material fabrication, the physics of the forces that direct assembly, and the engineering involved in designing hierarchical architectures.
