Nagoya Institute of Technology scientists in Japan have devised a method to convert fish waste into carbon nano-onions (CNOS) for LED lighting and QLED displays. This type of carbon nanostructure has a multitude of uses in biomedicine, bioimaging, energy conversion, and electronics. Unfortunately, the traditional methods for producing them are very complex, toxic, and resource-intensive.
This new method utilizes microwave pulses and waste fish scales to create extremely high-quality CNOs. These CNOs are essentially composed of concentric shells of fullerenes that look like nested cages, with their main advantage being a high surface area as well as large electrical and thermal conductivities. Why are LEDs important? Well, for one thing, they make this anamorphic wave illusion possible.
- High Capacity Portable Solar Power Charger: Built-in 36800mAh high capacity Lithium battery equipped with a high performance solar panel, anti-explosion, lightweight and reliable. Long lifespan with more than 1800 recharging times. which could recharge the battery itself under sunlight, eco-friendly and ideal for outdoor use.Made of durable and resistant ABS+PC Material which protect it from rain, dirt and shock.
- Very bright LED Light .This Portable Solar Charger built-in LED Lamp on the bottom and has Hook on the corner.The Flashlight is great choice for Camping,Hiking,Climbing,Fishing and Etc.With the Carabiner, it can be hang from the Gear like Backpack. A MUST-HAVE tool for ourdoor and urgent situations. Never afraid of darkness again. The power bank provides more convenience in your daily life or on your trip.
- The Solar Portable Charger Compatible with most devices:Built-in 2 USB Outputs with 5V/3.1A 18W PD fast charge, support QC 3.0 protocol. Able to fully charge the device quickly. It allows charger 3 Devices at the same time.Built-in smart transformer chip, compatible with most devices on the market such as iphone, ipad, Samsung, HTC, LG and other Android phones.As long as there is a suitable cable, it can also charge other devices such as watches, headsets, GPS, Gopro Camera,etc.
- The solar charger comes with a high-precision compass: Own comes with a portable compass, a handy tool for outdoor activities, like camping, cycling, fishing, traveling, hiking and beaches.
- Solar Charger: Solar power bank can recharge through by the outlet or the sunlight. It normally takes solar charging feature as an emergency purpose, rather than the main power source. The small panel size, large capacity and uncontrollable sunlight intensity, it is difficult to produce high intensity power from the sunlight resource.It is recommended to use a charger above 5V2A to charge the power bank in daily life.
These findings will open up new avenues for the development of next-generation displays and solid-state lighting. What is remarkable about this approach is that it needs no complex catalysts, nor harsh conditions, nor prolonged wait times; the fish scales can be converted into CNOs in less than 10 seconds!,” said the scientists.
