• Detonation technique to mass-produce graphene patented
  

  Forget chemicals, catalysts and expensive machinery -- a Kansas State University team of physicists has discovered a way to mass-produce graphene with three ingredients: hydrocarbon gas, oxygen and a spark plug. Their method is simple: Fill a chamber with acetylene or ethylene gas and oxygen. Use a more

• Tiny sensors tucked into cell phones could map airborne toxins in real time

  A tiny silicon chip that works a bit like a nose may one day detect dangerous airborne chemicals and alert emergency responders through the cell phone network. If embedded in many cell phones, its developers say, the new type of sensor could map the location and extent of hazards like gas leaks or more

• Ozone detection

  Researchers in Freiburg have developed a highly-sensitive, miniaturized mobile ozone sensor which can be used not only in air, but also in water and in the vicinity of explosive gases. The Fraunhofer Institute for Applied Solid State Physics IAF in Freiburg is developing improved chemical sensors t more
