1. Liquid Crystals

2. Overview First Discovered in 1890s while observing cholesterol Flow like liquids, but have a repeating crystalline pattern Have 2 melting points Reflect polarized light

3. 3 Different Types Depends on Temperature and Pressure Liquid Crystals only form under specific conditions

4. Thermotropic The most common type Flow like liquids Useful in liquid crystal displays (iphones)

5. Lyotropic Solvent provides fluidity Contains phospholipids Contains both hydrophobic and hydrophilic parts

6. Metalloropic Is essentially lyotropic, but with metals causing different melting points

7. Real World Applications Liquid crystal displays are in: Television screens (LCD display stands for liquid crystal display) Watch displays Cell phones Almost anything electronic with a screen.

8. More applications Soap Conducting foams Cholesterol
