• The effects of hydrogen on growing carbon nanotubes

  Carbon nanotubes -- long, hollow cylinders of carbon billionths of a meter in diameter -- have many potential uses in nanotechnology, optics, electronics, and many other fields. The exact properties of nanotubes depend on their structure, and scientists as yet have little control over that structure more

• Liquid method: pure graphene production

  In a development that could lead to novel carbon composites and touch-screen displays, researchers from Rice University and the Technion-Israel Institute of Technology unveiled a new method for producing bulk quantities of one-atom-thick sheets of carbon called graphene. When stacked together, grap more

• Paper strips can quickly detect toxin in drinking water

  A strip of paper infused with carbon nanotubes can quickly and inexpensively detect a toxin produced by algae in drinking water. Engineers at the University of Michigan led the development of the new biosensor. The paper strips perform 28 times faster than the complicated method most commonly used more

• Sum parameters "on trail"
  

  Identification of organic pollutants in wastewater is essential for performance evaluation, construction and operation of a wastewater treatment plant. Several parameters are currently used in wastewater analysis applications. The advantages of TOC analyses are apparent especially during continuous monitoring more
