GRAPHENE – A WONDER MATERIAL!
Development in science and technology has truly revolutionized our standard of living. Computers, smartphones, and smartwatches have become a part of our lives and we can’t afford to stay without them in this fast-moving world. But the batteries, which give the potential for our devices to work, drain quickly and its recharging is truly time-consuming, also the batteries are nonbiodegradable and a waste of natural resources.
GRAPHENE – A WONDEROUS MATERIAL:
So how about a material which will not only charge your phones within seconds but also is 200 times stronger than steel, conducts electricity better than silver, conducts heat better than diamond, can be used to make flexible touch screens, medical scanners, efficient and light spacecraft, automobiles, DNA sequencers, solar cells, to construct buildings, to store more data for computers, etc, etc. the list is too long because this light, strong, conductive, flexible and one atom thick material has the capability to revolutionize our world. The name of this wondrous material is “graphene”!!!
APPLICATIONS OF GRAPHENE:
Graphene is one atom thick carbon layer and was accidentally discovered by Andre Geim and Konstantin Novoselvo who got their Nobel prize in 2010 for their discovery. The carbon atoms in graphene are structured hexagonally and conduct electricity better than silver. This property has given rise to supercapacitors which store more electrons and would give an excellent battery experience.
Since graphene is flexible and a good body sensor, it can be used in making flexible and extremely slim mobile devises. It’s also biodegradable and very strong. Graphene solar cells would be able to store electricity which then can be used during the entire rainy season. Not only that, but graphene can do wondrous things in the medical field as well. It will help to sequence, understand DNA and sense or detect any kind of threat full disease efficiently.
DRAWBACKS OF GRAPHENE:
Graphene is truly an amazing material and has a wide range of applications. In spite of it being so wondrous material it has some engineering issues. Scientists and engineers are unable to find an efficient way to mass-produce this material. Presently graphene sheets can only be made in laboratories that also of a size of about a few millimeters. So it’s going to take some time to reach the public, but once graphene comes it will definitely change our standard of living. Another drawback of present graphene batteries is that they drain too fast.
However, there’s should be no doubt, why graphene is called a wonder material. Graphene in 2019 has a big outcome in nanoelectronics, automobile, wearable devices like an efficient transdermal fitness patch and contactless cards and keys. Graphene pavilion has a graphene layer beneath it, thus, there is no need for cables to be tunneled inside the wall. On another hand, this will keep the room cool from inside due to ease in the dissipation of heat.
