68 nanotimes News in Brief
Researchers at the NanoScience Center of the University of Jyväskylä, Finland, and at Harvard University, US, have discovered a novel way to make nanomaterials. Using computer simulations, the researchers have been able to predict that long and narrow graphene nanoribbons can be rolled into carbon nanotubes by means of twisting. The research has received funding from the Academy of Finland. The basic idea is simple and easily explained: just twist the ends of a strap on your backpack and watch what happens. Being classical in origin, the mechanism is robust and valid on the macro-, micro- and nanoscale.

A new online, searchable database for materials used in nanotechnology is now available. The Nanomaterial Registry was developed by RTI Inernational at a cost of $2.9 million in federal funding. The Nanomaterial Registry (NR) provides tools for analyzing and comparing data on the biological and environmental implications of well-characterized nanomaterials.
