Jo-Wilfried Tsonga became the latest star to crash out of Queen’s Club as the world No 10 was beaten 6-4, 6-4 by Luxembourg’s Gilles Muller on Wednesday.

After world No 1 Andy Murray, three-time grand slam champion Stan Wawrinka and former Wimbledon finalist Milos Raonic all endured shock first-round defeats on Tuesday, it was Tsonga’s turn to suffer a surprise second-round exit.

Fifth seeded Tsonga is traditionally a powerful force on grass and finished as Queen’s runner-up in 2011, while twice appearing in the Wimbledon semi-finals.

But the 32-year-old, who has won titles in Lyon, Marseille and Rotterdam in 2017, was out of sorts from start to finish against the big-serving Muller.

It took Muller just 69 minutes to hand Tsonga another frustrating loss on the heels of his embarrassing first round exit against Renzo Olivo at the French Open.

Muller’s impressive display maintained his recent surge, which has seen the 34-year-old win the ‘s-Hertogenbosch grass-court tournament last week and reach a career-high ranking of 26.

Muller is in the quarter-finals at the Wimbledon warm-up event for a third successive year and will play former Queen’s champion Sam Querrey or Australia’s Jordan Thompson for a place in the last four.

Donald Young reached the Queen’s quarter-finals for the first time as the American world number 55 defeated Serbia’s Viktor Troicki 6-3, 6-4.

Young, who arrived at Queen’s on a five-match losing streak, faces former US Open champion Marin Cilic or American qualifier Stefan Kozlov with a semi-final berth at stake.

UAE currency: the story behind the money in your pockets

What is a black hole?

1. Black holes are objects whose gravity is so strong not even light can escape their pull

2. They can be created when massive stars collapse under their own weight

3. Large black holes can also be formed when smaller ones collide and merge

4. The biggest black holes lurk at the centre of many galaxies, including our own

5. Astronomers believe that when the universe was very young, black holes affected how galaxies formed

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.
