through 100-nanometer nozzles, an order of magni- tude smaller than particle-based inks, an important feature for printed microelectronics. Moreover, the ink’s low viscosity makes it suitable for inkjet printing, direct ink writing or airbrush spraying over large, conformal areas.

Researcher at University of Tennessee, USA, col- laborated with researchers from the Massachusetts Institute of Technology and Ecole Polytechnique Federale in Switzerland to develop a process that improves the efficiency of generating electric power using molecular structures extracted from plants. They have developed a system that taps into photosynthetic processes to produce efficient and inexpensive energy.


Markus Buehler, an associate professor of civil and environmental engineering (CEE) at MIT, has previ- ously analyzed the complex, hierarchical structure of spider silk and its amazing strength. “Even if it


“This system is a preferred method of sustainable energy because it is clean and it is potentially very efficient,” said Bruce, who was named one of Ten Revolutionaries that May Change the World by Forbes magazine in 2007 for his early work, which first demonstated biosolar electricity generation. “As opposed to conventional photovoltaic solar power systems, we are using renewable biological materials rather than toxic chemicals to generate energy. Likewise, our system will require less time,
