In total, almost 912,000 cars were registered in the European Union. That was 3 percent less than a year earlier. In major markets such as Italy, Germany and France, sales fell by almost 7 percent. More than 28,000 new passenger cars were registered in the Netherlands.

Water shortages are increasingly occurring. This is the result of, on the one hand, the growing world population, global warming and the increasing desiccation and desertification occurring in increasingly larger parts of the world. Other factors that play an important role are increasing industrialization and urbanization, especially in Asia, as well as the expansion of agricultural land as a result of the growing demand for varied food products. The World Water Forum therefore makes an urgent appeal to take drastic measures. This underlines the need for accelerated investments and new innovative techniques leading to the largest growth market in the world.

The wonder material graphene can be used to generate energy. At room temperature, a sheet of the light but strong material does not hang still, but wrinkles back and forth. This thermal movement is barely visible. Researchers want to convert those tiny ripples into energy. The researchers at the University of Arkansas in the United States were not originally looking for an endless energy source. They wanted to see what the movement and structure of a sheet of graphene looks like at room temperature. To do this, they looked at the atomic structure of the material using scanning tunneling microscopy. They discovered that the material sometimes suddenly turns from concave to convex. This movement is caused by the fact that graphene is not perfectly flat. “The material forms a structure that resembles the shape of an egg carton,” says professor Paul Thibado of the University of Arkansas. The two-dimensional graphene therefore forms a three-dimensional structure. The peaks and valleys of the egg carton shape are not completely stable. Small random vibrations of the atoms in the graphene sometimes cause the upwardly bulged parts to suddenly fold over. The sudden change from convex to concave can be compared to the flipping over of a flat piece of metal that you press between your thumb and your index finger. Endless energy
