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.

Concept for a new storage medium
Physicists from Switzerland, Germany and Ukraine have proposed an innovative new data storage medium. The technique is based on specific properties of antiferromagnetic materials that had previously resisted experimental examination. Using nanoscale quantum sensors, an international research team has succeeded in exploring certain previously uncharted physical properties of an antiferromagnetic material.

Even multi-story timber buildings can safely survive compartment fires
Realistic full-scale fire experiments on the TUM Garching campus How safe are multi-story timber buildings in case of fire? This question is addressed by the "TIMpuls" research project, led by the Technical University of Munich (TUM). The scientists' objective is to establish valid basic principles for uniform regulations for the construction of multi-story timber buildings.

New research could boost a solar-powered fuel made by splitting water
Pritzker School of Molecular Engineering research could help make hydrogen useful, sustainable fuel Hydrogen is an incredibly powerful fuel, and the ingredients are everywhere-in plain old water. Researchers would love to be able to use it widely as a clean and sustainable energy source.  One catch, however, is that a considerable amount of energy is required to split water and make hydrogen.

In step toward autonomous materials, researchers design patterns in self-propelling liquid crystals
Materials capable of performing complex functions in response to changes in the environment could form the basis for exciting new technologies. Think of a capsule implanted in your body that automatically releases antibodies in response to a virus, a surface that releases an antibacterial agent when exposed to dangerous bacteria, a material that adapts its shape when it needs to sustain a particular weight, or clothing that senses and captures toxic contaminants from the air.

Novel sandwich technology improves sensitivity of rapid tests
Novel sandwich technology improves sensitivity of rapid tests
Scientists have developed a method for boosting the sensitivity of rapid-detection tests like those used for the new coronavirus. The results of their feasibility study have just been published in Nano Letters. Pregnancy tests and rapid-detection tests for the new coronavirus work in the same way. They contain a surface - usually made of metal - on which chemical nanosensors detect specific compounds in a sample of urine, saliva or blood that indicate the presence of a given protein or part of a virus.

The transforming power of light
A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt University of Berlin have found out that semiconductors can be converted to metals and back more easily and more quickly than previously thought. This discovery may increase the processing speed and simplify the design of many common technological devices.

Captured lithium
Captured lithium
Neutrons show effective lithium and electrolyte distribution in lithium-ion cells In our smartphones, our computers and in our electric cars: We use rechargeable lithium-ion batteries everywhere. But their capacity drops after a while. Now a German-American research team has investigated the structure and functionality of these batteries using neutron diffraction: They discovered that the electrolyte fluid's decomposition products capture mobile lithium in the battery and that the distribution of lithium within the cell is surprisingly uneven.

Newly-developed material could lead to lighter, safer car designs
A new form of 3D-printed material made by combining commonly-used plastics with carbon nanotubes is tougher and lighter than similar forms of aluminium, scientists say. The material could lead to the development of safer, lighter and more durable structures for use in the aerospace, automotive, renewables and marine industries.

Two-phase material with surprising properties
Two-phase material with surprising properties
Microstructure and macroscopic electro-mechanical properties are closely coupled in so-called ferroelectric polymers. An explanation for the high temperature dependence of this coupling has now been found at TU Wien. In certain materials, electrical and mechanical effects are closely linked: for example, the material may change its shape when an electrical field is applied or, conversely, an electrical field may be created when the material is deformed.

Droplets perform daredevil feats on gel surfaces
Droplets perform daredevil feats on gel surfaces
Scientists have succeeded in making droplets flow just as fast on soft surfaces as on hard ones by changing the surface texture. Welcome to the amazing world of soft substrates. These materials are made of silicon gels and have the same texture as panna cotta - but without the delicious flavor. They are used in a range of applications, especially in the pharmaceutical industry, because their biocompatible and antiadhesive properties make them resistant to corrosion and bacterial contamination.

Safe to cross: low risk of coronavirus infection from high-touch surfaces
Safe to cross: low risk of coronavirus infection from high-touch surfaces
Surfaces which are frequently touched by many different people may be contaminated with the coronavirus, but the risk of infection via this route is low. However, regular collection of samples from door handles, buttons or keypads could be useful for monitoring the course of the pandemic. Have you ever tried pressing the button at a pedestrian crossing with your elbow?

Origami with DNA
Origami with DNA
A team at TU Wien was able to answer important questions about the immune system - with a trick reminiscent of paper folding. T-cells are an important component of our immune system: with the receptors they carry on their surface, they can recognise highly specific antigens. Upon detection of an intruder, an immune response is triggered.

Comparative Study on Lithium-ion Battery Series Manufacturing and Alternative Technologies
Research on manufacturing battery cells is gaining momentum - and there is a strong need, considering the future demand for energy storage: For the year 2030, global production of rechargeable batteries will double from today's 750 gigawatt hours (GWh) per year to 1,500 GWh. A recently published review article in the magazine "Nature Energy" on cell production of various battery types suggests that the currently established lithium-ion batteries (LIB) dominate the market of rechargeable high-energy batteries in the coming years.
