Voltage from the parquet
Voltage from the parquet
Researchers at Empa and ETH Zurich have made wood compressible and turned it into a micro-generator. When it is loaded, an electrical voltage is generated. In this way, the wood can serve as a bio-sensor - or generate usable energy. The latest highlight: To ensure that the process does not require aggressive chemicals, naturally occurring wood-degrading fungi take over the task of modifying the wood.

Start small to answer big questions about photosynthesis
Start small to answer big questions about photosynthesis
New scientific techniques are revealing the intricate role that proteins play in photosynthesis. Despite being discovered almost 300 years ago, photosynthesis still holds many unanswered questions for science, particularly the way proteins organise themselves to convert sunlight into chemical energy and, at the same time, protect plants from too much sunlight.

The black gold of mushrooms
The black gold of mushrooms
Empa researchers have succeeded in extracting the pigment melanin in large quantities from a fungus. The gigantic Armillaria fungus in the service of science is one of the largest and oldest living organisms in the world. Potential applications for the "black gold" range from wood preservatives to the construction of water filters and historic musical instruments.

Researchers use sound to shape the future of printing
Researchers use sound to shape the future of printing
Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching. The scientists from the Universities of Bristol and Bath have shown that it's possible to create precise, pre-determined patterns on surfaces from aerosol droplets or particles, using computer-controlled ultrasound.

Energy house-keeping
Energy house-keeping
Energy management in a house with a solar system is becoming increasingly complex: When do I turn on the heating so that it is nice and cosy in the evening? How much electricity can the hot water tank hold? Will there still be enough energy for the electric car? Artificial Intelligence (AI) can help solve the problem: Researchers at Empa developed an AI control system that can learn all these tasks - and save more than 25 percent energy in the process.

New facility at University of Birmingham accelerates battery recycling research
Researchers working on the Faraday Institution ReLiB (Recycling and Reuse of Li-ion Batteries) project have completed the installation of new battery testing and storage facilities at the University of Birmingham. The new facilities will allow battery scientists and engineers to speed up their research to develop safe, economic and environmentally sound recycling routes that recover large volumes of valuable materials contained in batteries at the end of their first life.

Graphene filter makes carbon capture more efficient and cheaper
Graphene filter makes carbon capture more efficient and cheaper
Chemical engineers at EPFL have developed a graphene filter for carbon capture that surpasses the efficiency of commercial capture technologies, and can reduce the cost carbon capture down to $30 per ton of carbon dioxide. One of the main culprits of global warming is the vast amount of carbon dioxide pumped out into the atmosphere mostly from burning fossil fuels and the production of steel and cement.

Microchips of the Future: Suitable Insulators are Still Missing
Until now, hexagonal boron nitride was considered the insulator of choice for miniaturised transistors. New investigations by TU Wien (Vienna) show: this may not be the way to go. For decades, there has been a trend in microelectronics towards ever smaller and more compact transistors. 2D materials such as graphene are seen as a beacon of hope here: they are the thinnest material layers that can possibly exist, consisting of only one or a few atomic layers.

Light-emitting tattoo engineered for the first time
Scientists at UCL and the IIT -Istituto Italiano di Tecnologia (Italian Institute of Technology) have created a temporary tattoo with light-emitting technology used in TV and smartphone screens, paving the way for a new type of "smart tattoo" with a range of potential uses. The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos.

New Material is Next Step Toward Stable High-voltage Long-life Solid-state Sodium-ion Batteries
A team of researchers designed and manufactured a new sodium-ion conductor for solid-state sodium-ion batteries that is stable when incorporated into higher-voltage oxide cathodes. This new solid electrolyte could dramatically improve the efficiency and lifespan of this class of batteries. A proof of concept battery built with the new material lasted over 1000 cycles while retaining 89.3% of its capacity-a performance unmatched by other solid-state sodium batteries to date.

Magnetic effect without a magnet
Surprise in solid-state physics: The Hall effect, which normally requires magnetic fields, can also be generated in a completely different way - with extreme strength. Electric current is deflected by a magnetic field - in conducting materials this leads to the so-called Hall effect. This effect is often used to measure magnetic fields.
