Turning waste into gold
Turning waste into gold
Researchers have recovered the precious metal from electronic waste. Their highly sustainable new method is based on a protein fibril sponge, which the scientists derive from whey, a food industry byproduct. Transforming base materials into gold was one of the elusive goals of the alchemists of yore.

Innovative coating prevents limescale formation
Innovative coating prevents limescale formation
Wherever hot water flows, limescale is never far away. In households, this is a nuisance; in thermal power stations, it's an expensive problem. Now researchers at ETH Zurich have found an answer. Hot water tanks, washing machines, kettles: limescale forms in every domestic appliance that comes into contact with (hot) water - especially in areas where the water is hard, meaning high in calcium.

When nanoplastics are not what they seem
When nanoplastics are not what they seem
Textiles made of synthetic fibers release microand nanoplastics during washing. researchers have now been able to show: Some of the supposed nanoplastics do not actually consist of plastic particles, but of water-insoluble oligomers. The effects they have on humans and the environment are not yet well-understood.

Sound-powered sensors stand to save millions of batteries
Sound-powered sensors stand to save millions of batteries
Researchers at ETH Zurich have developed a sensor that utilises energy from sound waves to control electronic devices. This could one day save millions of batteries. Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power.

Soldering wounds with light and nano thermometers
Soldering wounds with light and nano thermometers
Not every wound can be closed with needle and thread. researchers have now developed a soldering process with nanoparticles that gently fuses tissue. The soldering technique is expected to prevent wound healing disorders and life-threatening complications from leaking sutures. The team recently published the promising method in the journal Small Methods and applied for a patent.

Laser additive manufacturing: listening for defects as they happen
Laser additive manufacturing: listening for defects as they happen
Researchers from EPFL have resolved a long-standing debate surrounding laser additive manufacturing processes with a pioneering approach to defect detection. The progression of laser additive manufacturing - which involves 3D printing of metallic objects using powders and lasers - has often been hindered by unexpected defects.
