- What comes after the lithium-ion battery?
The demand for batteries to store renewable energy will grow drastically in the coming years. Could we develop more sustainable technologies to save precious natural resources, besides the familiar... - New biosensor for COVID-19 virus
A team of researchers from Empa, ETH Zurich and Zurich University Hospital has succeeded in developing a novel sensor for detecting the new coronavirus. In future it could be used to measure the co... - Printing complex cellulose-based objects
Researchers from ETH Zurich and the Swiss Federal Laboratories for Materials Science and Technology (Empa) have set a new world record: they 3D printed complex objects with higher cellulose content... - Closely spaced hydrogen atoms could facilitate superconductivity in ambient conditions
An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades - a feature that could possibly f... - Tiny pharmaceuticals in the environment
Nanomedicine is making headways. However, the tiny nanoparticles that are being used as carriers for drugs could find their way into water, soil and air. Empa researchers are investigating potentia...
- Award for more efficient electrochemical energy storage
Empa young researcher Léo Duchêne received the prestigious Battery Division Student Research Award of the Electrochemical Society in Atlanta, USA. Since 1979, this research prize has been awarded t... - On the road to safe nanomedicine
Tiny particles that can fight cancer or that can easily pass through any interface within our body are a great promise for medicine. But there is little knowledge thus far about what exactly will h... - Fighting unwanted biofilms with novel materials
Biofilms are enormously resistant accumulations of germs, which can cause serious problems, especially in hospitals. Like a single large creature, they can spread within wounds or colonize implants... - Rössler Prize for work on bright nanoparticles
A brilliant blue, a luminous green, a deep red - the range of colours Maksym Kovalenko presents in an array of test tubes in his lab is fascinating. But what is fascinating about the colours isn't ... - Source of new CFC emissions discovered
Since 2013, annual emissions of the banned chlorofluorocarbon CFC-11 have increased by around 7,000 metric tons from eastern China, according to a new study by an international team of scientists i... - Microplastics in freshwaters - the risks to the environment
As small as a grain of dust - but of great global significance. The word microplastics is familiar to many, but the dangers are virtually unexplored. In recent years, plastic pollution has become a... - Unique insights into concrete - watching concrete explode
Even if concrete is not flammable, it can be hazardous in tunnel fires: high-performance concrete can explode at high temperatures. Although the phenomenon is well known, the physics behind it have... - Quantum cascade laser measures large molecules
Quantum cascade lasers are able to measure the smallest molecules with high precision. But the technology has failed to measure larger gas molecules - until now! Empa researchers have succeeded in ... - How safe is graphene? - Effects on people and the environment
Graphene is considered one of the most interesting and versatile materials of our time. The application possibilities inspire both research and industry. But are products containing graphene also s... - Hand-knitted Molecules
Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips - in a sen... - Rare metals from e-waste
This year, beautifully wrapped laptops, mobile phones or even new TV sets lay under numerous Christmas trees. They are enthusiastically put into use - and the old electronic devices are disposed of...
- Searching for undeclared carbon tetrachloride in the atmosphere
35,000 tons of undeclared carbon tetrachloride (CCl4) are released into our atmosphere every year - although applications in which this substance is released into the environment have been official... - What does graphene do in our lungs?
Graphene has been hailed as the material of the future. As yet, however, little is known about whether and how graphene affects our health if it gets into the body. A team of researchers from Empa ... - Special polymer scaffold for threedimensional cell cultures
For the replacement of animal testing with alternatives in medical rsearch, complex microtissues need to be cultivated. Researchers from Empa have developed a special polymer scaffold for threedime... - New materials for sustainable, low-cost batteries
The energy transition depends on technologies that allow the inexpensive temporary storage of electricity from renewable sources. A promising new candidate is aluminium batteries, which are made fr... - Measurement of noble gases in Antarctic ice cores
The average sea temperature is an essential parameter of the global climate - but it is very difficult to measure. At least until now, because an international team of researchers including Empa sc... - First step to a water-based, rechargeable battery
In the quest to find safe, low-cost batteries for the future, eventually we have to ask ourselves a question: Why not simply use water as an electrolyte? Water is inexpensive, available everywhere,...
- Novel solid sodium battery with the potential to store extra energy
Phones, laptops, electric cars - batteries are everywhere. And to meet the expectations of today's consumers, these batteries are increasingly lighter, more powerful and designed to last longer. Cu... - Low-cost battery from waste graphite
Lithium ion batteries are flammable and the price of the raw material is rising. Are there alternatives? Yes: Empa and ETH Zürich researchers have discovered promising approaches as to how we might... - Nanoparticles that stick wounds together
In spite of medical advances, wound-related complications arising after operations can still be life-threatening. In order to avoid these complications in the future, a new nanoparticle-based tissu...
