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.
As explained, man made 'wood' is a material constructed from the by-products of timber. As real timber is becoming more scarce (and therefore more expensive), it is neccessary and useful to produce artificial timber, which is relatively cheap, and sufficient for the job.Below are a list of the most common types of man made woods.lywood is such a product, and could almost be alluded as 'the titainium of (man made) woods.' Thin sheets of wood are glued together so that each grain is perpendicular to the last. Thickness ranges from as little as 3 sheet ply, all the way to (inch thick) 5 multiply.
