Quantum Dot Circuits
Cherie R. Kagan and Christopher B. Murray
Kagan and Murray fabricated the first electronic
circuits from nanometer scale semiconductor particles known as quantum dots.
These quantum dots are synthesized in solution and tailored in the shape of
cubes so when they are assembled into solids, they fill space. The nanoscale cubes allow for high
performance thin film electronics. The chemistry developed further allowed
these circuits to be realized on plastics for flexible electronic applications.

Soft Spots in Disordered Colloidal Packings
Andrea J. Liu and Arjun G. Yodh
Like
liquids, solids can flow under applied shear stresses. In crystalline solids, figuring out vulnerable regions where the material will break under stress is
well-established—they are typically controlled by a population of defects in
the crystal structure known as dislocations.
In disordered solids, however, defects are everywhere, making the task
of identifying such vulnerable spots
much more daunting.

Imaging 'Invisible' Dopant Atoms in Semiconductor Nanocrystals
Andre Mkhoyan, David Norris
In semiconductor nanocrystals, the physical effects of deliberately included impurities, called dopants, may depend on the dopant position with the crystal.

Why Most Plastics Can't be Metals
Chris Leighton, Dan Frisbie
Conductive polymers, i.e. plastics, that conduct electricity, are important in science and technology as they offer the potential for cheap, flexible electronic devices.
