The following scenario highlights the importance of bump testing: Peter works at a local oil refinery and arrives on site in ...

  • Electrified nanostructure high-speed filter

    Stanford researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric (ordinary cotton) with nanotubes and silver nanowires and then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world. By dipping plain cotton cloth in a ...
