Innovative Sustainable LEDs Created from Fish Scales
Written on
Chapter 1: Introduction to Sustainable LEDs
In a remarkable breakthrough, researchers from the Nagoya Institute of Technology in Japan have discovered a method to produce carbon nano-onions (CNOs) using fish scales. This innovative approach not only utilizes waste but also presents exciting possibilities for creating sustainable LEDs.
This story resonates with me as I recently enjoyed barramundi and fries for lunch, a treat during my time in Queensland, Australia.
Section 1.1: The Process of Creating CNOs
The team microwaved fish scales, a method typically frowned upon in cooking, as it usually leads to undesirable results. However, this unconventional technique has proven effective in producing CNOs in under ten seconds.
CNOs, also referred to as multi-layer fullerenes, differ from their tube-shaped counterparts, carbon nanotubes. Instead, CNOs are formed of concentric fullerene layers, resembling the structure of an onion.
Section 1.2: Benefits and Challenges of CNO Production
Traditionally, producing CNOs has been a complex and energy-intensive process, often requiring extreme conditions or costly materials. The breakthrough from this Japanese team circumvents these hurdles, allowing for the rapid transformation of fish scales into CNOs without the need for harsh catalysts or extensive wait times.
Chapter 2: The Remarkable Properties of CNOs
The research indicates that the CNOs generated from fish scales exhibit unique optical characteristics, achieving a quantum yield of 40%. This is a significant improvement compared to previous methods, suggesting that these CNOs could be used in various applications, including the development of LED technology.

The stability of these emissions is noteworthy, as they remain effective in both solid-state devices and various solvents. Imagine a liquid with LED properties—this concept is being explored by the research team, although no visual demonstrations are currently available.
Section 2.1: Potential Applications and Environmental Impact
The prospect of crafting thin emissive films at a low cost presents an exciting opportunity for the future of sustainable technology. However, questions remain regarding the overall carbon footprint of this process—perhaps a new term, "carbon fishscale," is in order.
As I reflect on my recent experiences sailing along the Great Barrier Reef, where we caught and consumed our own fish, the idea of creating CNOs from scales is intriguing, albeit impractical without the right equipment.

In conclusion, while I may not have the means to experiment with creating CNOs on my boat, the research into transforming fish scales into sustainable materials opens up fascinating avenues for future innovations.
The original research paper is available in Green Chemistry for those interested, albeit at a steep price. Meanwhile, I’ll continue to enjoy my barramundi and fries, possibly dreaming of future fishing adventures that could yield even more innovative discoveries.
