Kiel researchers have developed a sophisticated technology that allows components to be firmly joined together even without welding. For this, the surfaces are first roughened targeted. The resulting barbs interlock. And are glued. This keeps you rock-solid.

Not only metals can be firmly joined together without welding. Plastics also adhere extremely tightly (more…)

Corrosion causes gigantic costs. It is estimated that there are nearly 2.7 trillion euros in corrosion costs worldwide. However, conventional coatings often contain toxic heavy metals. Potsdam researchers have now developed a technology that is more sustainable and protects much longer. The model is the human skin with its self-healing powers.

The rust on this BMW i8 is not real, but has mimicked the US company MetroWrapz only by foil. But rust is responsible for billions of damages. Now Max Planck researchers have developed a protective mechanism that is supposed to stop corrosion in the neck.

Sperm are musical and navigate the chord. ‘So what?’ Some think. But this realization is crucial. Because it opens the door for innovation in microrobotics.

Pipelines are the lifelines of modern life, bringing gas to people as well as taking wastewater away. But leaks can lead to dangerous failures. Two new research projects are now revealing affordable solutions.

This textile fiber from Texas is really a miracle thing: even the slight movement of one breath is enough to generate electricity. Twistron could not only replace the batteries in heart rate monitors or light-emitting diodes, but could also use the wave power of the oceans to generate much more power than previously possible. Even data transmission for the Internet of Things would be possible.

Runners at the Berlin Marathon 2017: US researchers have developed a yarn that generates so much energy only from the body movements while running that so that clock and heart rate monitor can be operated

A teenager from Houston, Texas, has developed a filter sponge that removes 99% of all heavy metals from polluted water. Five liters of water have freed the researchers around Perry Alagappan in less than a minute from the toxic substances. The super filter is cleaned with plain vinegar.

Effective Waaser filter: The quartz wool coated with carbon nanotubes releases 99% of heavy metals from water.

A newspaper that speaks to you? A handkerchief that serves as a microphone? Sounds kind of off-beat. But would already be possible today. Thanks to the so-called Feng film. It can produce and record sounds.

Australian researchers have developed nanocrystals that could replace the previously heavy and energy-consuming night vision devices. But the invention can not only be used by soldiers, policemen or hunters.

Student Maria del Rocio Camacho-Morales co-developed the nanocrystals in Canberra, which make a night-vision device out of normal glasses ,

The world is colorful and could soon become even more colorful. For scientists with the participation of the Karlsruhe Institute of Technology (KIT) have succeeded in creating colors through nanostructures that retain their color regardless of the viewing angle. It has been a natural preserve so far.

What does Jérôme Boateng do if he does not like photos? He puts on a scarf called Ishu. Why the star of the European Football Championship in France becomes invisible on photos, read here.
