QLED screens and fish may have much more in common in the future than you think. And the answer will thank your pocket.
Just as you read it. These two products that, apparently, have nothing to do with each other. In the future they could be very related. And it turns out that a team of scientists from the Nagoya Institute of Technology in Japan have achieved something unthinkable. They developed a method that is capable of converting fish waste into carbon nano-onions (CNOS) of very high quality. And why is this important? Because the CNOS is what is used to create new LED lighting systems and cheaper QLED screens. That is why we told you that the result could be appreciated by your pocket: Because it is much cheaper.

Finding the CNOS is not very easy to say. This is a form of nanomaterial that is carbon-based with low toxicity, chemical stability, and excellent electrical, thermal, and optical properties, with a high surface area. Ideal for making electronic devices. This type of material was discovered in the 1980s, but its production is very complicated. High temperature, vacuum and a long time, are part of the ‘recipe’ to obtain it, which does not make them very sustainable. This new method promises to be much simpler, with fewer requirements, and also helps dispose of fish waste.
So effective is this method that it is capable of converting flakes to CNO in 10 seconds using microwave pyrolysis. The strangest thing is that researchers have not yet determined the reason why it is so easy to convert scales to CNO. One hypothesis is collagen, which absorbs enough microwave radiation to produce a rapid rise in temperature. It is no longer necessary to reach extreme temperatures or use complex catalysts. The result offers high crystallinity that has great optical properties. Additionally, they can be used to create large-area emissive flexible films, leaving the door open for the next generation of displays.
