An unlikely marriage among oxides
21-Jun-2018
Sebastian Siol is looking for new materials with unusual properties that were so far not accessible in experiments. To do this, he connects partners who don't really fit together: One partner forces the other into a state that would not be possible without the unlikely pairing. Siol also makes ...
Batteries with better performance and improved safety
28-Nov-2017
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. Currently the core technology for these applications is lithium ion batteries. But the technology is ...

One step ahead towards the artificial heart
09-Nov-2017
An artificial heart would be an absolute lifesaver for people with cardiac failure. However, to recreate the complex organ in the laboratory, one would first need to work out how to grow multi-layered, living tissues. Researchers at Empa have now come one step closer to this goal: by means of a ...
Sticking instead of stitching
Nanoparticles that stick wounds together
10-Oct-2017
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 tissue glue has been developed by researchers at Empa. There are internal and external areas of the body ...
Nanomaterial helps store solar energy: efficiently and inexpensively
Field trials show that new catalyst material for electrolysers is reliable
19-Jul-2017
Efficient storage technologies are necessary if solar and wind energy is to help satisfy increased energy demands. One important approach is storage in the form of hydrogen extracted from water using solar or wind energy. This process takes place in a so-called electrolyser. Thanks to a new ...
Sodium and magnesium to replace lithium in batteries
03-May-2017
A project supported by the Swiss National Science Foundation (SNSF) aims to find new materials which can be used in rechargeable batteries and eventually provide alternatives to the current lithium batteries. Lithium-based batteries have several drawbacks, such as the limited availability of the ...
Single crystal measures radioactivity
Affordable detectors for gamma radiation
21-Sep-2016
A research team at Empa and ETH Zurich has developed single crystals made of lead halide perovskites, which are able to gage radioactive radiation with high precision. Initial experiments have shown that these crystals, which can be manufactured from aqueous solutions or low-priced solvents, work ...
How nanoparticles flow through the environment
13-May-2016
Carbon nanotubes remain attached to materials for years while titanium dioxide and nanozinc are rapidly washed out of cosmetics and accumulate in the ground. Researchers from the National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64) have developed a new model to track ...
Structure of 'concrete disease' solved
09-Nov-2015
Researchers from the Paul Scherrer Institute (PSI) teamed up with colleagues from the Swiss Materials Science Lab Empa to study a degenerative sign of ageing in concrete: the so-called alkali-aggregate reaction (AAR). In the course of AAR, a material forms that takes up more space than the ...
A GPS from the chemistry set
Color trail shows quickest route to destination
29-Oct-2014
Empa scientists teamed up with colleagues from Hungary, Japan and Scotland to develop a chemical “processor” which reliably shows the fastest way through a City maze. As the method is basically faster than a satnav system, it could be useful in transport planning and logistics in the future, for ...
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
