Copolymers block out new approaches to microelectronics

NIST researchers reported at the March Meeting of the American Physical Society how they have improved manipulation of so-called block copolymers - polymers made of a mixture of two or more different molecule building blocks that are tethered at a junction point - which can form arrays of tiny dots that could be used as the basis for electronic components that pack terabytes (1000 gigabytes) of memory in something as small as a pack of gum.

Nanomaterials show unexpected strength under stress

In yet another twist on the strangeness of the nanoworld, researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park have discovered that materials such as silica that are quite brittle in bulk form behave as ductile as gold at the nanoscale. Their results may affect the design of future nanomachines.
