X-rays have been identified as one of the most energetic forms of light in the Universe over the years, and their power has been harnessed to create scanners in airports and radiotherapy. However, it's only now that their true power is starting to be tapped into, researchers announce. Scientists at the University of North Carolina (UNC), in Chapel Hill, have recently revealed that they may have discovered a method of allowing for real-time, 3-dimensional X-ray scans, by generating them using carbon nanotubes, Nature News informs. “If you look at current imaging technology, technically very little has changed since Wilhelm Rontgen discovered X-rays more than 100 years ago,†UNC Materials Scientist Otto Zhou, who has been one of the main researchers behind the new study, explains. He and colleagues in his team found that carbon nanotubes could be potent sources of radiation when their own X-ray machine broke down. “It didn't take long to show that nanotubes could gene!
rate X-rays in principle. What has taken time is turning this idea into a viable technology,†he adds. Zhou says that, in the average X-ray machine, a tungsten filament releases some electrons, which are then accelerated inside a tube until they finally hit a metal target. The large force of the blast creates ...
