1 Genuine 23K Gold Leaf is available in books with 25 sheets measuring 3-1/8 x 3-1/8. 2  The sheets are referred to as leaves.  Our leaf is the finest European leaf available.
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.
These types of crystals are made up of small molecules that hold themselves together using weak electrical forces. There is also quite a bit of space between these small molecules. These types of crystals have low melting points and are good insulators. Diamonds. Diamonds are a good example of a crystal that is made up of large molecules. They are created from a large molecule that is put together in three dimensions. Diamonds are made only of carbon atoms, and each carbon atom is bonded to four other carbon atoms that are at equal distance to each other and are grouped around it.
