Graphene is a single layer of carbon atoms arranged like honeycomb.

It was discovered in 2004, when Russian-born Manchester scientists Andrei Geim and Kostya Novoselov were "playing about" with sticky tape and graphite - the material used as "lead" in pencils.

Placing the tape on the graphite and peeling it, they managed to rip off thin flakes of carbon. In the beginning they got flakes consisting of many layers of graphene. But as they repeated the process many times, the flakes got thinner.

By separating the graphite fragments repeatedly, they managed to create flakes that were just one atom thick. Their experiment had led to graphene being isolated for the very first time.

At the time, many believed it was impossible for such thin crystalline materials to be stable. But examined under a microscope, the material remained stable, and when tested was found to have incredible properties.

It is many times times stronger than steel, yet incredibly lightweight and flexible. It is electrically and thermally conductive but also transparent. The world's first 2D material, it is one million times thinner than the diameter of a single human hair.

But the 'sticky tape' method would not work on an industrial scale. Since then, scientists have been working on manufacturing graphene, to make use of its incredible properties.

In 2010, Geim and Novoselov were awarded the Nobel Prize for Physics. Their discovery meant physicists could study a new class of two-dimensional materials with unique properties.

If you’re going to go grey, a great style, well-cared for hair (in a sleek, classy style, like a bob), and a young spirit and attitude go a long way, says Maria Dowling, founder of the Maria Dowling Salon in Dubai.
It’s easier to go grey from a lighter colour, so you may want to do that first. And this is the time to try a shorter style, she advises. Then a stylist can introduce highlights, start lightening up the roots, and let it fade out. Once it’s entirely grey, a purple shampoo will prevent yellowing.
“Get professional help – there’s no other way to go around it,” she says. “And don’t just let it grow out because that looks really bad. Put effort into it: properly condition, straighten, get regular trims, make sure it’s glossy.”
