Current Review chemicool Here’s a look at the remarkable properties of ten of the periodic table’s elements. The first on our list was hailed as the philosophers’ stone when it was discovered. 1. Phosphorus Phosphorus was the first element ever isolated scientifically. In 1669 Hennig Brand evaporated water from urine, then allowed the residue to fester for a few months. What is a synchrotron? A synchrotron is an extremely powerful source of X-rays. These are produced by highly energetic electrons moving in a large circle in the synchrotron. The entire world of synchrotron science depends on one physical phenomenon: When a moving electron changes direction, it emits energy. When the electron is moving fast enough, the emitted energy is at X-ray wavelength.
Introduction to Soapmaking In kitchens, garages, basements, and other homely spaces, people all over the country make their own soap. For some, it is a hobby; for others it is a microbusiness venture. For still others, it is a way of life and livelihood, employing a full staff of artisans. If you talk to people who make soap, you find a number of common threads. The most marked is what is called “the addiction.”
Science for Kids Water is an amazing substance! It can form into a beautiful snowflake in its solid state or evaporate into the air as a gas. Experiment with solids, liquids and gases to learn more about these states of matter. How do objects move?

theconversation Science is like high-performance racing: today’s Formula One machine is all too soon the jalopy of tomorrow. The Australian Synchrotron, opened in 2007 and located in Melbourne, is currently at the F1 end of the spectrum. Needless to say, its 120 staff and thousands of active researchers would like to keep it that way. Which raises a pertinent and obvious question: what does it actually do? Technically speaking, a synchrotron is a large machine that accelerates electrons to almost the speed of light. As those electrons are deflected through magnetic fields they create extremely bright light, meaning a synchrotron is also a “light source”. home - Practical Chemistry This website is for teachers of chemistry in schools and colleges. It is a collection of experiments that demonstrate a wide range of chemical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Chemistry is a practical science.
