Latest Molecular knot Stories
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 JyvÃ¤skylÃ¤ (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...

- Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
- Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
