what is a man made molecules
Invisible to the naked eye, the objects are 12 nm (12 billionths of a meter) wide. That's big for a nanoscale molecule. It's huge, said Hla, an associate professor of physics and astronomy. This man-made fractal molecule resembles a Star of David.This man-made structure is one of the first nanoscale, non-branched fractal molecules ever produced, said Newkome, who is lead author on the study's paper (published online today by the journal Science).ractals are irregular curves or shapes that retain the same pattern when reduced or magnified. The molecule in the study, for example, is composed of six rings, which are made up of six smaller rings, and so on, Hla said. Snowflakes, broccoli florets or tree bark would be just a few examples from nature.
