Readers turn over new leaf



Book retailers in the UAE say sales have been hampered by thrifty consumers who are increasingly turning to cheaper e-books to sate their appetites for literature. Book sales have bounced back from last year's slump but the growing popularity of e-book readers such as Amazon's Kindle has cut into demand for printed editions, said Jeremy Brinton, the chief executive of the Magrudy's.

What is graphene?

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.

Electoral College Victory

Trump has so far secured 295 Electoral College votes, according to the Associated Press, exceeding the 270 needed to win. Only Nevada and Arizona remain to be called, and both swing states are leaning Republican. Trump swept all five remaining swing states, North Carolina, Georgia, Pennsylvania, Michigan and Wisconsin, sealing his path to victory and giving him a strong mandate. 

 

Popular Vote Tally

The count is ongoing, but Trump currently leads with nearly 51 per cent of the popular vote to Harris’s 47.6 per cent. Trump has over 72.2 million votes, while Harris trails with approximately 67.4 million.
