In electroplating electrical energy provides electrons to convert metal ions into atoms. A thin metal coating is deposited on a surface to protect it or to make it more beautiful. Electroplating is used to apply a thin layer of gold to a cheap jewelry base...
Green chemistry and the shoe industry
By: Madhusoodanan K.P
Green chemistry consists in integrating chemical processes and naturally available materials, with the object of achieving sustainable development. That means for any product to be used, the manufacturer as well as the consumer/end user should be aware that there is no adverse impact on the...
Beginner's guide to copper electroplating
By: Susan Kristoff
Copper electroplating is the process of adding a thin layer of copper to a metal base part using an electric current. Copper is often plated over other metals to improve electrical conductivity or appearance. Due to the high cost of copper, many parts that were...
Aviation Technology: Understanding jet engine metallurgy
By: Susan Kristoff
A jet engine in an aircraft is subjected to very harsh conditions during operation, including high temperatures, vibrations, and mechanical stresses. In order to withstand these environmental effects, jet engine components have to be manufactured using specific materials and alloys. Each part of the engine...
How to make liquid magnets
By: Brian Dodson
Liquid magnets, also known as ferrofluids, are colloidal suspensions of nanometer-scale magnetic materials in a liquid medium. A typical ferrofluid might comprise about 5% by volume of iron oxide particles roughly 10 nanometers in size, about 85% of a carrier fluid, such as kerosene, and...
Green chemistry: Plastics
By: Glen Brizius
Green Chemistry is making great leaps and bounds in the area of plastics. Plastics are ubiquitous in our everyday life - we can scarcely imagine life without them. However, the preparation and processing of plastics is a nasty, environmentally-messy process that generates vast amounts of...
Aviation Technology: Understanding jet engine metallurgy
By: Madhusoodanan K.P
The production of aircraft engines requires very special materials to meet stringent quality standards and specifications. Operating at high altitudes and high speeds, and subject to many vicissitudes of nature such as cyclones, snow etc these engines have to be designed with zero tolerance against...
The chemistry behind the explosive mixture of oxygen and hydrogen
By: James Harris - 554809
Hydrogen has 1 electron in its valence shell, while oxygen has six, this gives hydrogen one bonding spot and oxygen two bonding spots so the two elements are always combined in a two to one ratio in a bent molecule that we call water. Hydrogen...
Christmas 2009: Hottest new chemistry books for children
By: Ramona Taylor
Christmas 2009 is more than about about snow and Santa. For some families, it's about science! Not every kid wants dolls and trucks for Christmas and for some parents, finding the right present for their budding mad scientists can be precarious! For those brainy kids...

There was a time when recycling alone made a household or a company “green.” Now green chemistry requires adherence to EPA’s twelve Principles of Green Chemistry and the elimination of plastics labeled with the numbers 3, 6, and 7. EPA defines green...
