Does graphene have a patent?
The earliest mention of graphene appears in a patent published 12 December 1994, having a priority dating back to 1991 and assigned to UCAR Carbon Technology Corporation [6]. No subsequent patent filings were made under this name.
Who makes flash graphene?
chemist James Tour
Machine learning fine-tunes flash graphene
The process discovered two years ago by the Rice lab of chemist James Tour has expanded beyond making graphene from various carbon sources to extracting other materials like metals from urban waste, with the promise of more environmentally friendly recycling to come.
Who has patents in graphene?
China holds the most graphene patents with 2,024 or 30%. Next up is the US with 1,754 or 23% and lastly is South Korea with 1,160 or 15%. Graphene has been described as a new wonder material with applications for batteries, renewables and many other uses.
Who has the patent on graphene oxide?
Victor Medina and Chris Griggs receive U.S. Patent 10,414,659 for their method of recycling chitosan and graphene oxide compound for water purification purposes.
What is flash graphene?
The “flash” part is that, via a “flash treatment,” electrodes induce a high voltage and high current into a sample of carbon-rich waste. Ten milliseconds and 3,300 degrees Kelvin later, you’ve created a usable form of graphene. At $30-35 in electricity costs per ton, the process is highly economical.
What is the patent number of graphene?
Family Applications (1)
| Application Number | Title | Filing Date |
|---|---|---|
| EP11770149.0A EP2625139A1 (en) | 2010-10-07 | Graphene oxide |
When was flash graphene invented?
2020
The “flash” process, introduced by Tour and his colleagues at Rice University in 2020, has now been optimized to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete.
What is Turbostratic graphene?
Turbostratic graphene is comprised of multiple graphene layers with interlayer rotations that alleviate orbital hybridization resulting in carrier mobilities similar to that of SLG.
Can coal be turned into graphene?
Ohio University researcher, Dr. Gerrardine Botte, has developed a simple method of producing graphene from inexpensive and widely available coal. The process begins by subjecting ground coal to electrolysis. The resulting coal char is used as a carbon source for graphene growth via chemical vapor deposition (CVD).
Is Apple investing in graphene?
Apple, for instance, has been awarded several patents for designs that incorporate graphene, including graphene solar panels printed inside the touch screen to allow constant recharging; an entire smartphone that can be folded in half; a heat dissipater that would prevent smartphones from overheating; and a graphene-
Who is the biggest producer of graphene?
The Canadian corporation NanoXplore led the market for graphene producing companies worldwide as of May 2021, with an estimated market capitalization of 428 million U.S. dollars at that time, which was around 85 million U.S. dollars more than the next ranked leading company.
Which country has most graphene?
China
In 2020, the total worldwide production of graphite amounted to 1.1 million metric tons, a decrease from the 2016 total of 1.15 million metric tons. In the past decade, China has consistently been the leading global graphite producer.
Who invented graphene oxide?
For the first time graphene oxide was synthesized by Benjamin Brody in 1859 much earlier than graphene was discovered [6]. He invented method of making the graphite oxide. It consisted in oxidation and exfoliation of natural crystalline graphite and undoubtedly gave a noticeable amount of single layer graphene oxide.
Does the military use graphene?
Graphene has many applications as well, but the most remarkable ones are in the military. It is used for the manufacturing of robots, ballistic protection, to reduce the weight of protection armour, in aviation and for the manufacturing of lightweight, comfortable and protective helmets.
What is justia patent?
Patents are property rights granted to an inventor in order to exclude others from making, using, selling, or importing a particular invention.
How do you make graphene flash?
As reported in Nature, flash graphene is made in 10 milliseconds by heating carbon-containing materials to 3,000 Kelvin (about 5,000 degrees Fahrenheit). The source material can be nearly anything with carbon content.
How do you turn graphene into plastic?
Flash graphene made from plastic by Rice University scientists begins as post-consumer plastic received from a recycler. It is then mixed with carbon black and processed into turbostratic graphene via timed pulses of AC and DC electricity.
How do you make graphene composites?
Graphene-based composite materials
Graphene is a material with a huge amount of outstanding qualities; strength, flexibility, lightweight and conductivity. One of the simplest and most effective ways of harnessing the potential of graphene is to combine it with existing products – so called composite materials.
Who owns graphene?
GMG is a clean-technology company that has developed and proved its own proprietary production process to manufacture Graphene powder from readily available low-cost feedstock. This process produces high quality, low cost, scalable, ‘tuneable’ and contaminant-free graphene.
How was graphene invented?
They took a hunk of graphite and used Scotch tape to peel off layer after layer after layer. Geim and Novoselov then analyzed what they had left, and found graphene. For their discovery – which was published in 2004 – they were awarded the 2010 Nobel Prize in Physics.
