A group of scientists has recently developed a new method for producing hydrogen out of water. As the most abundant natural resource on the planet, water can be used for a variety of purposes, albeit only if it's broken down into its basic components, hydrogen and oxygen. In the new experiments, experts managed ... |

Carbon nanotubes are, at this point, some of the most promising materials that science is developing. They are very tiny, and yet incredibly strong, and hold great promise for uses in medicine, biology and the electronics industry, among others. However, producing them is a very complex process, which relies on using... |

Since the beginnings of chemistry, reactions between some compounds have been found to need a little something called a catalyst in order to function. Catalysts are chemicals or other factors, such as pressure and heat, which must also be present between two or more chemicals, in order for reactions to take place. On... |
