For the first time, MIT researchers have incorporated a plant’s ability to convert sunlight to energy into a solid-state electronic “spinach sandwich” device that may one day power laptops and cell phones.
At the heart of the device is a protein complex dubbed Photosystem I (PSI). Derived from spinach chloroplasts, PSI is 10 to 20 nanometers wide. Around 100,000 of them would fit on the head of a pin. “They are the smallest electronic circuits I know of,” said researcher Marc A. Baldo, assistant professor of electronic engineering and computer science at MIT.
Baldo and other researchers from MIT, the University of Tennessee and the U.S. Naval Research Laboratory, including electrical and biomedical engineers, nanotechnology experts and biologists, collaborated on the world’s first solid-state photosynthetic solar cell. The work was reported in NanoLetters, a publication of the American Chemical Society. “We have crossed the first hurdle of successfully integrating a photosynthetic protein molecular complex with a solid-state electronic device,” Baldo said.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
