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

A Crystal Clear Reflection of Reality In the middle of the billions of people in this planet‚ we are made. In the middle of the widest plain in our world‚ we are found. Why? It is because of the existence our so-called purpose. It was the day the world had a glimpse of another blessing from God. It is not a matter of logical thinking but spiritually speaking‚ we are also made because of God’s purpose. We came into this world with an unknown future waiting for us. Just like what

less acknowledged—techniques is crystal healing. Crystal healing is a brand of alternative medicine that involves specific crystals being placed on specific parts of the body. These specific placements are because the crystals correspond to chakras that allow the body of the treated person to have accelerated healing. There are a large amount of healers who currently use this technique to treat their patients today. There are many cases where the patients of crystal healers have improved their condition

quite solid‚ neither is it a liquid. Liquid crystals are another important intermediate phase which exhibits features from both the solid and the fluid state. Liquid crystals have the ordering properties of solids but they flow like liquids. Liquid crystalline materials have been observed for over a century but were not recognized as such until 1880s. In 1888‚ Friedrich Reinitzer (picture) is credited for the first systematic description of the liquid crystal phase and reported his observations when

PIEZOELECTRICITY AND APPLICATIONS Piezoelectricity is the ability of some materials such as crystals and certain ceramics‚ to generate an electric potential in response to applied mechanical stress or heat. If the piezo crystals are not short-circuited‚ the applied charge induces a voltage across the material. The word Piezo is derived from the Greek “Piezein”‚ which means to squeeze or press. The piezo material exhibits both “Direct piezo electric effect” as well as ‘Converse piezo electric

Each grain of sugar is made of a small crystal that is made of an arrangement of molecules called sucrose. In a sugar crystal‚ the sucrose molecules are arranged in a pattern that extends in all three dimensions‚ and all of these molecules are attracted to each other by a type of interaction that binds molecules together called intermolecule forces. When you add granulated sugar to water‚ some of the sucrose molecules start separating from one another because they are attracted to the water molecules

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
