Improved Efficiency and Reduced Costs with Self-Assembling
Nanostructures  By Will Soutter  In the quest for efficient and
lower cost energy solutions, a structure that builds itself
offers an intriguing solution. Harnessing self-assembly can
allow complex nanostructures to be produced without intricate
fabrication processes. These self-assembling structures can be
used to create continuous sheets of materials for thermoelectric
devices and solar cells.  Self-assembled "nano-flowers" created
by Harvard researchers  The Nanoscale Challenge  Structures on
the scale of 1-100 nanometers have been shown to have
fascinating properties, distinct from the bulk-scale properties
of the material they are made of. Accessing this range of
structure-based properties has had an immense impact on the
worlds of medicine, green energy, and advanced materials in
countless applications.  However, these tiny structures are very
difficult to create and manipulate. A nanometer is one millionth
of a millimeter - at this scale, in be
