http://www.paksc.org , Simple Method to produce oxygen and hydrogen Concept: Zinc and manganese dioxide can be taken out from the used dry battery. Oxygen and hydrogen are produced by using the acid, the hydrogen peroxide and the two materials of the dry battery. The property of oxygen and hydrogen is examined. How to make oxygen […]

Drawing carbon nanotubes on paper at MIT

Carbon nanotubes offer a powerful new way to detect harmful gases in the environment. However, the methods typically used to build carbon nanotube sensors are hazardous and not suited for large-scale production. A new fabrication method created by MIT chemists — as simple as drawing a line on a sheet of paper — may overcome […]
