Graphene is the world’s first 2D material. Graphene is a two-dimensional honeycomb arrangement of carbon atoms that is revolutionizing technology. The word “graphene” refers to a single-layer sheet of hexagonally-arranged carbon atoms.
It was first studied in Manchester in 1947. The term graphene first appeared in 1987 to describe single sheets of graphite as a constituent of graphite intercalation compounds (GICs), conceptually a GIC is a crystalline salt of the intercalant and graphene.The first samples of graphene were made using sticky tape.The word “graphene” is sometimes used interchangeably with the term “carbon nanotubes” or CNTs.
It is one million times thinner than paper.
It is one million times smaller than the diameter of a single human hair.
It is 200 times stronger than steel, but it is incredibly flexible.
It has no band gap. It helps to produce transistors.
It is better than silver at conducting.
It is 100 times lighter than aluminum.
It is more conductive than copper.
Solar cells rely on semiconductors to absorb sunlight. Semiconductors are made of an element like silicon and have two layers of electrons. Using graphene would also allow cells that are hundreds of thousands of times thinner and lighter than those that rely on silicon.
Graphene could be used to distillate saltwater to make it drinkable. Graphene could also be immensely helpful in purifying water of toxins.Passing sea water through Graphene’s tiny pores, the crystal lattice could let water molecules through, while blocking out the atoms that make salt.
Graphene can be used as a coating to improve current touch screens for phones and tablets.This makes it perfect for use in portable electronics. Graphene has a high carrier mobility, and low noise, allowing it to be used as the channel in a field-effect transistor.
A team of researchers at MIT has designed one of the strongest lightweight materials known, by compressing and fusing flakes of graphene, a two-dimensional form of carbon. This 3-D forms of Graphene material, a sponge-like configuration with a density of just 5 percent, can have a strength 10 times that of steel.
Scientists in China are developing a new kind of graphene coated solar panel that could be used to generate power from rain drops.By using a thin layer of highly conductive graphene, the solar cell could effectively harness power from rain. The salt contained in rain separates into ions (ammonium, calcium and sodium), making graphene and natural water a great combination for creating energy.
Creating light in small structures on the surface of a chip is crucial for developing fully integrated “photonic” circuits. But researchers were not able to put the light bulb into a chip, as the light bulb filaments must be extremely hot in order to glow, and micro-scale metal wires cannot withstand such temperatures.
Researchers have developed World’s Thinnest Light Bulb using Graphenethat works in the same way as the filament in a light bulb. By measuring the spectrum of the light emitted from the graphene, the team was able to show that the graphene was reaching temperatures of above 2500 degrees Celsius, hot enough to glow brightly.
