Climate-Relevant Exchange Processes between Atmosphere and Ocean
Environmental physicist Bernd Jähne from Heidelberg University is pursuing a new approach to exploring the processes that ensue with the exchange of climatically relevant gases and volatiles between the atmosphere and the ocean. To this end, the scientist will use two imaging measurement procedures for experiments in the Heidelberg Aelotron, a wind-wave tank.

Comparative Study on Lithium-ion Battery Series Manufacturing and Alternative Technologies
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.

Heavy charge against water germs
Heavy charge against water germs
Removing pathogens from drinking water is especially difficult when the germs are too tiny to be caught by conventional filters. Researchers at Empa and Eawag are developing new materials and processes to free water from pathogenic microorganisms such as viruses. Water is life, biology teaches us. Reality teaches us something different: Water contaminated with pathogens causes hundreds of thousands of deaths each year in places where water treatment is lacking or poorly functioning.

Crystal structures in super slow motion
Crystal structures in super slow motion
Physicists from Göttingen first to succeed in filming a phase transition with extremely high spatial and temporal resolution Laser beams can be used to change the properties of materials in an extremely precise way. This principle is already widely used in technologies such as rewritable DVDs. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they have so far eluded direct observation.

Secrets to solar success
Secrets to solar success
A new study shows how researchers at The Australian National University (ANU) achieved a world record in solar cell efficiency. The study focused on perovskite solar cells - made using a special group of materials which are cheap and easy to manufacture. The group achieved 21.6 per cent efficiency in converting sunlight into electricity, a new record for perovskite solar cells larger than one square centimetre in size.

New metamaterial offers reprogrammable properties
New metamaterial offers reprogrammable properties
Scientists have developed a metamaterial whose mechanical properties can be reprogrammed on demand and whose internal structure can be modified by applying a magnetic field. Over the past 20 years, scientists have been developing metamaterials, or materials that don't occur naturally and whose mechanical properties result from their designed structure rather than their chemical composition.

Making Masks Smarter and Safer Against COVID-19
A new tool for monitoring COVID-19 may one day be right under your nose. Researchers at the University of California San Diego are developing a color-changing test strip that can be stuck on a mask and used to detect SARS-CoV-2 in a user's breath or saliva. The project, which received $1.3 million from the National Institutes of Health, is aimed at providing simple, affordable and reliable surveillance for COVID-19 infections that can be done daily and easily implemented in resource-poor settings.

New self-assembly method creates bioelectronics out of microscopic structures
Bringing together soft, malleable living cells with hard, inflexible electronics can be a difficult task. UChicago researchers have developed a new method to face this challenge by utilizing microscopic structures to build up bioelectronics rather than creating them from the top down-creating a highly customizable product.

Innovative Battery Chemistry Revolutionises Zinc-Air Battery
Innovative Battery Chemistry Revolutionises Zinc-Air Battery
High-performance, eco-friendly, safe and at the same time cost-effective: the zinc-air battery is an attractive energy storage technology of the future. Until now, the conventional zinc-air battery has struggled with a high chemical instability, parasitic reactions which rooted in the usage of alkaline electrolytes lead to electrochemical irreversibility.

Detective work in theoretical physics
Detective work in theoretical physics
Scientific articles in the field of physics are mostly very short and deal with a very restricted topic. A remarkable exception to this is an article published recently by physicists from the Universities of Münster and Düsseldorf. The article is 127 pages long, cites a total of 1075 sources and deals with a wide range of branches of physics - from biophysics to quantum mechanics.

Scientists pioneer new method of measuring electricity in cells
Electricity is a key ingredient in living bodies. We know that voltage differences are important in biological systems; they drive the beating of the heart and allow neurons to communicate with one another. But for decades, it wasn't possible to measure voltage differences between organelles-the membrane-wrapped structures inside the cell-and the rest of the cell.

Since 1970 a worldwide unique test has been running in the Empa testing hall in Dübendorf, in which the long-term behaviour of bonded steel reinforcements on a concrete beam is being investigated. Investigations such as these have contributed to the fact that adhesive-bonded reinforcement is now state of the art as a strengthening method and that engineers have confidence in this retrofitting method.

Skyrmions are small magnetic objects that could revolutionize the data storage industry and also enable new computer architectures. However, before they can be utilized in such applications, there are still a number of challenges that need to be overcome. A team of Empa researchers has now succeeded for the first time in producing a tunable multilayer system in which two different types of skyrmions - the future bits for "0" and "1" - can exist at room temperature, as they recently reported in the renowned .
