Bulletproof vest material for use in body armor. Graphene is manufactured from carbon and is the thinnest, strongest, and most conductive material on the planet. Taking the form of hexagonally arranged atoms, its tensile strength is known to be 200 times greater than steel, but studies from Rice University have revealed it is also 10 times better than steel at dissipating energy, an ability that had previously not been thoroughly explored. To test its properties, the University of Massachusetts stacked together graphene sheets only a single carbon atom thick, creating layers ranging in thickness from 10 nanometers to 100 nanometers from 300
Asymmetric carbon atoms are not attached to exactly the same things, there are two different "groups" of atoms that the carbon atom in question is attached to, therefore making it an asymmetric carbon atom: A tetrose with 2 asymmetric carbon atoms has 2 = 4 stereoisomers: An aldopentose with 3 asymmetric carbon atoms has 2 = 8 stereoisomers: An aldohexose with 4 asymmetric carbon atoms has 2 = 16 stereoisomers: The four groups of atoms attached to the carbon atom can be arranged in space in two different ways that are mirror images of each other, and which lead to so-called left-handed
