X-ray vision and eavesdropping ensure quality
X-ray vision and eavesdropping ensure quality
With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams.

Wavy surfaces for better light control
Wavy surfaces for better light control
Researchers at ETH Zurich have developed a method for the production of wavy surfaces with nanometre precision. In the future this method could be used, for instance, to make optical components for data transmission on the internet even more efficient and compact. The importance of light-based technologies for our society was demonstrated once more in recent weeks.

Laser allows solid-state refrigeration of a semiconductor material
Laser allows solid-state refrigeration of a semiconductor material
To the general public, lasers heat objects. And generally, that would be correct. But lasers also show promise to do quite the opposite - to cool materials. Lasers that can cool materials could revolutionize fields ranging from bio-imaging to quantum communication. In 2015, University of Washington researchers announced that they can use a laser to cool water and other liquids below room temperature.

Growing polymers with different lengths
Growing polymers with different lengths
ETH researchers have developed a new method for producing polymers with different lengths. This paves the way for new classes of polymer materials to be used in previously inconceivable applications. It is hard to imagine everyday life without materials made of synthetic polymers. Clothes, car parts, computers or packaging - they all consist of polymer materials.

Super-strong surgical tape detaches on demand
Super-strong surgical tape detaches on demand
Removable adhesive could make it easier for surgeons to close up internal wounds. Last year, MIT engineers developed a  double-sided adhesive  that could quickly and firmly stick to wet surfaces such as biological tissues. They showed that the tape could be used to seal up rips and tears in lungs and intestines within seconds, or to affix implants and other medical devices to the surfaces of organs such as the heart.

Nanoresearch without animal experiments
Nanoresearch without animal experiments
In order to reduce the number of animal experiments in research, alternative methods are being sought. This is a particular challenge if the safety of substances that have hardly been studied is to be ensured, for instance, the completely new class of nanomaterials. To accomplish just that, Empa researchers are now combining test tube experiments with mathematical modelling.

Newly observed phenomenon could lead to new quantum devices
Exotic states called Kohn anomalies could offer clues to why some materials have the electronic properties they do. An exotic physical phenomenon known as a Kohn anomaly has been found for the first time in an unexpected type of material by researchers at MIT and elsewhere. They say the finding could provide new insights into certain fundamental processes that help determine why metals and other materials display the complex electronic properties that underlie much of today's technology.

Stiffer roadways could improve truck fuel efficiency
Study finds simple changes in road resurfacing practices could improve gas mileage for heavy vehicles and reduce greenhouse gas emissions. Every time you hear a deep rumble and feel your house shake when a big truck roars by, that's partly because the weight of heavy vehicles causes a slight deflection in the road surface under them.
