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.
Today people can make new kinds of molecules in laboratories and factories. Some of the biggest molecules that people make are plastics, like what plastic garbage bags or plastic Legos are made of. Plastics are also hydro-carbon molecules.People also make new molecules for medicines.rotein molecules-each dot is one molecule. A molecule is a group of two or more Atoms that stick together. Molecules (MOLL-uh-cyools) are so small that nobody can see them, except with an electron microscope. Pretty much everything on Earth and other planets is made of molecules, and so is some of the dust in space.
