Fe 3 C with the fixed composition Fe-6.7 wt % C bounds one end of this diagram and pure iron the other end. Pure iron can have two different crystal structures as its temperature is increased from ...
Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...
The bifocal lenses are made from bilayer structures of liquid crystal (LC) cells and LC polymer. These lenses split light with a left-handed circular polarization (LCP) into two focused light ...
