Polymer Structures Serve as “Nanoreactors” for Nanocrystals with Uniform Sizes and Shapes

Using star-shaped block co-polymer structures as tiny reaction vessels, researchers have developed an improved technique for producing nanocrystals with consistent sizes, compositions and architectures — including metallic, ferroelectric, magnetic, semiconductor and luminescent nanocrystals. The technique relies on the length of polymer molecules and the ratio of two solvents to control the size and uniformity of colloidal nanocrystals.

Squashed nanotubes may be ripe with new possibilities for scientists, according to a new study by Rice University.
Researchers at Rice’s Richard E. Smalley Institute for Nanoscale Science and Technology have come up with a set of facts and figures about carbon nanotubes that appear to collapse during the growth process; they found that these unique configurations have properties of both nanotubes and graphene nanoribbons.
