Watching single protons moving at water-solid interfaces
Scientists at EPFL have been able to observe single protons moving at the interface between water and a solid surface. Their research reveals the strong interactions of these charges with surfaces. The H+ proton consists of a single ion of hydrogen, the smallest and lightest of all the chemical elements.

Understanding ceramic ’mortar’ of materials may reveal ways to improve them
When most people think of ceramics, they might envision their favorite mug or a flowerpot. But modern technology is full of advanced ceramics, from silicon solar panels to ceramic superconductors and biomedical implants. Many of those advanced polycrystalline ceramics are combinations of crystalline grains which, at the microscopic level, resemble a stone fence held together with limestone mortar.

Lossless conduction at the edges
Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining experimental proof of this behavior, physicists from the University of Basel have expanded the pool of candidate materials for topological superconductivity.

Solar energy farms could offer second life for electric vehicle batteries
Modeling study shows battery reuse systems could be profitable for both electric vehicle companies and grid-scale solar operations. As electric vehicles rapidly grow in popularity worldwide, there will soon be a wave of used batteries whose performance is no longer sufficient for vehicles that need reliable acceleration and range.

Team of Canadian and Italian researchers breaking new ground in materials science
A study by a team of researchers from Canada and Italy recently published could usher in a revolutionary development in materials science, leading to big changes in the way companies create modern electronics. The goal was to develop two-dimensional materials, which are a single atomic layer thick, with added functionality to extend the revolutionary developments in materials science that started with the discovery of graphene in 2004.

Machine-learning tool could help develop tougher materials
Engineers develop a rapid screening system to test fracture resistance in billions of potential materials. For engineers developing new materials or protective coatings, there are billions of different possibilities to sort through. Lab tests or even detailed computer simulations to determine their exact properties, such as toughness, can take hours, days, or more for each variation.

Making Quantum ’Waves’ in Ultrathin Materials
Study co-led by Berkeley Lab reveals how wavelike plasmons could power up a new class of sensing and photochemical technologies at the nanoscale Wavelike, collective oscillations of electrons known as "plasmons" are very important for determining the optical and electronic properties of metals. In atomically thin 2D materials, plasmons have an energy that is more useful for applications, including sensors and communication devices, than plasmons found in bulk metals.

Working up a sweat could power future wearable devices
A new generation of wearable devices could be powered by human sweat instead of conventional, environmentally-unfriendly batteries, scientists say. In a new paper published today in the journal Advanced Materials, engineers from the Bendable Electronics and Sensing Technologies (BEST) group at the University of Glasgow describe how working up a sweat could be enough to generate power for exercise monitors and other electronic devices in the future.

Laser loop couples quantum systems over a distance
For the first time, researchers have succeeded in creating strong coupling between quantum systems over a greater distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly lossless exchange of information and strong interaction between them. In the scientific journal Science, the physicists from the University of Basel and University of Hanover reported that the new method opens up new possibilities in quantum networks and quantum sensor technology.

Researchers map tiny twists in "magic-angle" graphene
Results could help designers engineer high-temperature superconductors and quantum computing devices. Made of a single layer of carbon atoms linked in a hexagonal honeycomb pattern, graphene's structure is simple and seemingly delicate. Since its discovery in 2004, scientists have found that graphene is in fact exceptionally strong.

Filtering out toxic chromium from water
EPFL chemists have developed sponges to capture various target substances, like gold, mercury and lead, dissolved in solution. The sponges are actually porous crystals called metal organic frameworks, and now one exists for capturing toxic hexavalent chromium from water. Hexavalent chromium continues to contaminate water sources around the world, with one US company fined just this February for having put employees at risk.

Going against the trend
Global warming has affected the entire planet's surface, except for one particular area of the ocean, which has bucked the trend. A research team comprising scientists from ETH Zurich and Princeton University has unravelled the causes of this conundrum. Climate and marine scientists are observing pervasive warming of the ocean and the land surfaces across the globe.

New material engineered to capture carbon dioxide emissions
Researchers at UCL and Newcastle University have developed a new class of self-forming membrane to separate carbon dioxide from a mixture of gases. Operating like a coffee filter, it lets harmless gases, such as nitrogen, exit into the atmosphere and allows the carbon dioxide to be processed separately.

Less gold is Sometimes Better
Using an ultra-thin gold layer, scientists at TU Wien (Vienna) succeeded in creating an almost optimal infrared absorber. Possible applications range from astrophysics to virus detection. Infrared detectors play an important role in research: many molecules absorb electromagnetic radiation in the infrared range in a very characteristic way.

Largest amount of microplastics found on ocean floor
Our researchers have helped record the highest level of microplastics ever found on the ocean floor - with up to 1.9 million pieces in an area of just one square metre. The discovery highlights the problem of plastic pollution in our seas, 99 per cent of which lies beneath the waves. Working as part of an international team the researchers have shown how deep-sea currents act as conveyor belts, transporting tiny plastic fragments and fibres across the seafloor.
