Cooking Oil is 200 times Stronger than Steel Made by Scientists
This is a new way of making graphene, cheaper and faster. Australian scientists have found a way to turn cooking oil that we use everyday into graphene, a metamaterial that has extremely wide variety of applications. This technique helps to reduce costs and travel time to produce graphene so many times.
Graphene is a material has many beneficial properties Vietnam, it is 200 times stronger than steel, harder than diamonds but extremely flexible. Even, under certain conditions, graphene can turn into a superconductor electricity with zero resistance.

These properties of graphene make it can be used to create a better electronic equipment, solar panels with higher performance and even can be used in medicine. Last year, a study said that graphene can increase battery life by up to 25% smartphone and this material can also fuel from the air filter. However, the ability of graphene applications are still limited by the material production costs are extremely high. Typically, to produce graphene we need to use crystalline materials made in vacuum conditions at high temperatures.
Do not found a way of making graphene has cheap rates should still be used only in the laboratory. But recently, Australian scientists have found a way to produce graphene at room temperature from cheap soybean oil.

“The process to produce graphene at room temperature is very fast, simple, secure, capable of replication and high application”, Zhao Huan Jun, a researcher involved in the project shared. “This unique technology can reduce our production costs and improve the ability of graphene applications of this material.”
According to the researchers, graphene fabrication method called “GraphAir” Their conduct by taking soy oil into the heated oven for 30 minutes so that it decomposes into carbon blocks. Then, this carbon is quenching the workpiece is made of nickel. In nickel ingot, carbon will diffuse into graphene sheets 1 nanometer thick rectangle (about 80,000 times thinner than a human hair).
Graphene fabrication techniques are not only easier but also cheaper and faster than other methods. Scientists often take up to several hours to produce graphene in vacuum conditions. According to Zhao, this technique can reduce the cost of manufacturing graphene down 10 times. Not only that, it also creates a more sustainable option for the recycling of cooking oil. “Now we can recycle discarded cooking oil instead and turn them into something useful,” Seo Dong Han, a researcher involved in the project shared.

The question is whether the new graphene fabrication techniques can be replicated or not. Though new techniques of Australian scientists is extremely great, but it only created a graphene sheet with a size of 5 × 2 cm.
The team said that graphene has the largest size they once created by a major credit card. To really create graphene can be used in commercial purposes, the scientists need to produce large-sized graphene sheets than the present. The team are currently seeking commercial partners to pursue the goal of manufacturing large-sized graphene sheet. Last week, a team from the University of Kansas has also filed a patent describing how to produce graphene with hydrocarbon gases, oxygen and a spark plug, no need to vacuum.
