17 February 2017 Current Affairs: A group of scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) created a high-quality grapheme, world's strongest material, using soybean.
Graphene is a carbon material that is one atom thick.
The research was published in the journal Nature Communications.
Highlights of the Research : The scientists developed a novel "GraphAir" technology, which does not require a highly-controlled environment.
The technology grows graphene film in ambient air with a natural precursor. It makes its production faster and simpler.
The ambient-air process for graphene fabrication is fast, simple, potentially scalable, integration-friendly, and safe.
GraphAir transforms soybean oil into graphene films in a single step. It results in good and transformable graphene properties, comparable to graphene made by conventional methods.
Soybean oil, with heat, breaks down into a range of carbon building units that are necessary for the synthesis of graphene.
The team also transformed other types of renewable and waste oil into graphene films.
Graphene is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattice in which one atom forms each vertex. It can be considered as an indefinitely large aromatic molecule.
It is about 200 times stronger than the strongest steel.
It efficiently conducts heat and electricity and is nearly transparent.
The potential uses of graphene include water filtration and purification, sensors, personalised healthcare, renewable energy, medicine and so on.
