Chirality – Isolation of Limonene from Citrus Fruits Introduction: Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons‚ grapefruits‚ limes‚ and tangerines contain the compound as well. The

head movement tracking can be added to support the user with motion parallax depth cue and increase the realism of the presented images. It is a kind of glasses made of LC Shutter Glasses. They are different from the glasses which are made of polarizer and the anaglyph glasses which are made of red and blue color filter. Generally‚ they can only work for CRT Display‚ i.e. CRT Monitor‚ CRT Projector and TV. According to different applications‚ it can be used on education‚ entertainment‚ presentation

Encoding Information with Light’s Orbital Angular Momentum Light is the future of communication‚ traveling at 3‚000‚000 meters per second‚ the cosmic speed limit of the universe. Its tremendous speed makes it optimal for data transmission. The conventional method to encode information in light is through amplitude modulation‚ i.e. light pulses‚ time division multiplexing‚ i.e. delaying the time light beams enter a channel‚ and wavelength multiplexing‚ i.e. multiple beams of light in one channel
