A new generation of lighter, stronger plastics could be produced using an intricate chemical process devised by scientists A new generation of lighter, stronger plastics could be produced using an intricate chemical process devised by scientists. Chemists working on the nanoscale — 80,000 times smaller than a hair's breadth — have managed to tie molecules into complex knots that could give materials exceptional versatility. By weaving threads of atoms into the shape of...

A research team headed by Professor David Leigh of the University of Edinburgh (UK) and Academy Professor Kari Rissanen of the University of Jyväskylä (Finland) have made the most complex molecular knot to date, as reported in Nature Chemistry (DOI:10.1038/NCHEM.1193, published online Nov. 6 2011). Knots can be found in DNA, proteins and even in the molecules that make up man-made plastics, where they often play an important role in the substance's properties...
