The design and engineering of the ancient tile vaulting technique
employed in the construction was done by John Ochsendorf, Class of 1942
Career Development Professor in the Department of Architecture, and
Michael Ramage MArch ’06, currently a lecturer at the University of
Cambridge. Also from SA+P, Matt Hodge SM ’07 conducted material
research for the tiles and Philippe Block SM ’05, PhD ’09 reviewed the
structural design using the Thrust Network Analysis he developed for
his PhD.
This illustration shows a lead sulfide quantum dot array. Each quantum dot (the colored clusters) is 'passivated' by molecules that bind to its surface. Dots that are made up of unequal amounts of lead and sulfur tend to cause electrons (shown in red) to become highly localized, which can substantially lower the electrical transport of the device.Image: Donghun Kim and Jeffrey C.

Balance is key to making quantum-dot solar cells work
MIT team finds that the ratio of component atoms is vital to performance.
