The Chemical Universe i ? ! @ Chemistry is the study of atoms Atoms are the building blocks of nature How many atoms are there in a cup of tea? ? ! 15 ,000 ,000 ,000 ,000 ,000 ,000 ,000 ,000 @ Chemical Science is shaping our future

Chemistry of Flowers Smell a Flower See a Flower Touch a Flower The Fragrance is Chemistry See a Flower The Colours are Chemistry Touch a Flower The Structure is Chemistry

Chemistry in the Home i ? ! @ Everything in your home is Chemistry Shower Gel, Wallpaper, Baked Beans… Teflon™ was discovered by accident Energy efficient, colour changing buildings ? ! @

Paints Pigment Matte Paints Non-Drip Paints Particles to add colour Particles to add texture Non-Drip Paints Polymers to change consistency

Improved Performance i ? ! @ Our leisure time has been changed by Chemical Science Computer parts, sports equipment Carbon fibre is 3 times stronger than steel Better flat screen displays i ? ! @

Flat Screen Displays The past The present The future Cathode ray tubes Liquid Crystals Plasma displays The future Light emitting polymers Electronic Ink Most people are familiar with Liquid Crystal Displays (watches, calculators, laptops etc.) and also Plasma displays (the extremely expensive flat screen TVs people envy in department stores). But other technology is being developed for flat screen technology. New advances in LCD technology can make the screens flexible (currently they have to be sandwiched between glass) see http://www.extra.research.philips.com/technologies/paintdisp/ For more details. Light emitting polymer technology also allows flexible displays, but unlike LCD’s does not need a separate backlight. More information on the technology at http://www.cdtltd.co.uk The concept of electronic paper – displays that look and feel like a sheet of paper, with the same definition, is being developed with electronic ink technology. The advantage of this technology is that once an image is set, no more power is required. More information at: http://www.eink.com
