Why the UAE has many reasons to celebrate its closest friend and ally

Dobromir Radichkov, chief data officer at dubizzle and Bayut, offers a few tips for UAE residents looking to earn some cash from pre-loved items.

1. Sellers should focus on providing high-quality used goods at attractive prices to buyers.
2. It’s important to use clear and appealing photos, with catchy titles and detailed descriptions to capture the attention of prospective buyers.
3. Try to advertise a realistic price to attract buyers looking for good deals, especially in the current environment where consumers are significantly more price-sensitive.
4. Be creative and look around your home for valuable items that you no longer need but might be useful to others.

Trump tests positive: everything we know so far

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.

• Canada and Mexico are significant energy suppliers to the US, providing the majority of oil and natural gas imports
• The introduction of tariffs could hinder the US's clean energy initiatives by raising input costs for materials like nickel
• US domestic suppliers might benefit from higher prices, but overall oil consumption is expected to decrease due to elevated costs
