Engineers work to create new biomaterials with energy technology applications

When automotive engineers want to create a new car, they don’t build thousands of prototypes. Instead, they create computer models and run simulations for performance, efficiency and desirability before a model is selected for fabrication.

University of Delaware materials science professors Darrin Pochan and Kristi Kiick are taking a similar approach to building new nanomaterials from biomolecules — namely peptides and proteins — that could increase the efficiency of photovoltaics, also known as solar cells, and other electronic devices.

UCLA physicists have made nanomechanical measurements of unprecedented resolution on protein molecules.

The new measurements, by UCLA physics professor Giovanni Zocchi and former UCLA physics graduate student Yong Wang, are approximately 100 times higher in resolution than previous mechanical measurements, a nanotechnology feat which reveals an isolated protein molecule, surprisingly, is neither a solid nor a liquid.

“Proteins are the molecular machines of life, the molecules we are made of,” Zocchi said. “We have found that sometimes they behave as a solid and sometimes as a liquid. (more…)
