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.

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.

50 years old and as good as new
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.

How to power up battery manufacturing in India
India will need to make the switch from coal to renewable energy to meet its ambitious decarbonization goals. Batteries could be key to meeting these targets and represent an opportunity to develop the country's battery manufacturing industry. India is one of only a few countries whose national emissions reduction target is in line with the Paris Agreement's goal of reducing global warming before Earth's temperature reaches a dangerous threshold.

Big step with small whirls
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 .

When less is more: a single layer of atoms boosts the nonlinear generation of light
A wide array of technologies, ranging from lasers and optical telecommunication to quantum computing rely on nonlinear optical interaction. Typically, these nonlinear interactions, which allow a beam of light, for example, to change its frequency, are implemented by bulk materials. In a new study an international research team led by the University of Vienna have shown that structures built around a single layer of graphene allow for strong optical nonlinearities that can convert light.
