Prairie Meadows Scholarship Industrial Engineering has always been an interesting career for me. My step father is an industrial engineer. I have been to his work and watched him and thought it was intriguing‚ so I decided it is the career I want to pursue. He has shown me a lot of different things he does at work. Designing things using autocad is what he does a lot. I have taken autocad classes in high school and thought they were easy‚ I understood what I was doing‚ and thought it was interesting

LIQUID CRYSTALS Introduction What are Liquid crystals ? Its History & Discovery Any of various liquids in which molecules are regularly arrayed like a solid crystal along one or two dimensions‚ but are free in the other dimensions as with typical liquids. Liquid crystals often display unusual and often manipulable optical properties such as anisotropic scattering. They can be divided into two classes‚ Thermo tropic(nematic‚ chiral nematic‚ and smectic.) and Lyotropic. Transitions to thermotropic

Piezoelectric crystals are one of many small scale energy sources. Whenever piezoelectric crystals are mechanically deformed or subject to vibration they generate a small voltage‚ commonly know as piezoelectricity. This form of renewable energy is not ideally suited to an industrial situation. The ability of certain crystals to generate Piezoelectricity in response to applied mechanical stress is reversible in that piezoelectric crystals‚ when subjected to an externally applied voltage‚ can change
