A robot inspired by earthworms
Scientists from the Adolphe Merkle Institute and Case Western Reserve University (Cleveland, USA) have developed a flexible robot, inspired by earthworms, that can squeeze into small spaces and move in all directions regardless of the surface . Soft robots with worm-like mechanical properties and shape can, in principle, move over rough terrain and into tight spaces inaccessible to other robots.

Shape memory for nano-sized objects
Researchers at ETH Zurich achieved a shape memory effect for the first time with objects that are only a few nanometers in size. This can be used to manufacture tiny machinery and robotic devices on the nanoscale. Alloys that can return to their original structure after being deformed have a so-called shape memory.

Forecast for accidents with nanomaterials
Researchers have for the first time estimated how probable the accidental release of nanomaterials will be in the future. They based this on models from the nuclear industry. For a risk assessment, the results now have to be linked to information about the hazardous nature of the materials. Every year, more than two million tonnes of nanomaterials are produced and used for a wide variety of consumer goods.

Go-ahead for digitally manufactured concrete staircase
The next unit at NEST, the research and innovation building of Empa and Eawag, goes by the name of STEP2. For about two years, partners from research and industry have been working on various innovations in the fields of circular economy, digital and industrial fabrication, building envelope and energy systems, turning them into products ready for market entry.

3D printing with bacteria-loaded ink produces bone-like composites
Researchers have published a method for 3D-printing an ink that contains calcium carbonate-producing bacteria. The 3D-printed mineralized bio-composite is unprecedently strong, light, and environmentally friendly, with a range of applications from art to biomedicine. Nature has an extraordinary knack for producing composite materials that are simultaneously light and strong, porous and rigid - like mollusk shells or bone.

New corrosion protection that repairs itself
Researchers have developed an extraordinary protection against corrosion after a chance discovery. It glows in places where it is not damaged, repairs itself - and can be reused multiple times. Skyscrapers, bridges, ships, aeroplanes, cars - everything humans make or build sooner or later decays. The ravages of time are known as corrosion; nothing is safe from it.

Health risk of graphene residues investigated
Researchers have studied residues from the incineration of graphene-containing plastics. Conclusion of the study: Burned composite materials containing graphene nanoparticles can be considered harmless in case of acute exposure. Due to its exceptional properties, graphene is now added to a wide range of plastics.

Chromo-encryption method encodes secrets with color
In a new approach to security that unites technology and art, researchers have combined silver nanostructures with polarized light to yield a range of brilliant colors, which can be used to encode messages. Cryptography is something of a new field for Olivier Martin, who has been studying the optics of nanostructures for many years as head of the Nanophotonics and Metrology Lab EPFL's School of Engineering.

Improving perovskite solar cell resistance to degradation
Despite their huge potential, the way perovskite solar cells respond to external stimuli - such as heat or moisture - has a considerable impact on their stability. Researchers at EPFL have identified the cause of degradation and developed a technique to improve stability, bringing us closer to widespread adoption of these cost-effective and efficient solar cells.
