New conductivity mechanism of ions discovered
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion ...
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 ...
Affordable detectors for gamma radiation
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 ...
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 ...
Researchers of the University of Basel and Empa have gotten a step closer to engineering artificial muscles: they have developed a method to generate nanometer-thin silicone films. Elastomers, which can transform electrical energy into mechanical energy, have a wide variety of applications, i.e. ...
When electrons spin differently
As reported by the journal Nature, researchers from Empa, the Max Planck Institute in Mainz and the Technical University of Dresden have for the first time succeeded in producing graphene nanoribbons with perfect zigzag edges from molecules. Electrons on these zigzag edges exhibit different (and ...
EU project TREASORES finishes successfully
In November 2012, the TREASORES project (Transparent Electrodes for Large Area Large Scale Production of Organic Optoelectronic Devices) started with the aim of developing technologies to dramatically reduce the production costs of organic electronic devices such as solar cells and LED lighting ...
Swiss innovation for measuring particulate emissions from aircraft engines
Since the 1980s, large aircraft engines have been required to meet emission limits that have been gradually tightened over time. Air traffic, therefore, contributes relatively little to Switzerland's pollution levels, and visible smoke trails in the sky from jet engines are a thing of the past. ...
High-performance lithium ion batteries face a major problem: Lithium will eventually start to run out as batteries are deployed in electric cars and stationary storage units. Researchers from Empa and ETH Zurich have now discovered an alternative: the “fool’s gold battery”. It consists of iron, ...
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 ...
