With ecoinvent, the Paul Scherrer Institute and its partners at ETH Zurich, ETH Lausanne, Empa and Agroscope have been running the world’s leading database for life cycle inventories for over ten years. The latest ecoinvent version 3 collects new data in areas such as electricity generation, agriculture, transport, mining and chemicals. In the power sector, which is significant for life cycle assessments, the database now covers over 80 per cent of the global production. And technology that has not been considered thus far such as enhanced geothermal systems is to be included in ecoinvent from now on. The result is more accurate ecological assessments of products and services

The Lattice-Boltzmann Method was developed in the early 1990s as a calculation approach to solve the Boltzmann equation numerically, i.e. with the aid of computers. Researchers from the Paul Scherrer Institute PSI have now extended the Lattice-Boltzmann Method’s field of application with a new model that is able to describe more complex processes.Their work opens a window to more realistic computer simulations of many complex technical processes. Applications are expected in the microporous structures of most technical catalysts, diesel particle filters, combustion microreactors or fuel cells

Aerosols are small particles in the atmosphere. They can influence the global climate by way of direct absorption or scattering of solar radiation, or by acting as nuclei for cloud formation. Efforts by scientists to exactly quantify these effects and then improve climate models are impeded by the lack of a global network of aerosol measurement stations. To remedy this situation, researchers at the Paul Scherrer Institute to facilitate continuous aerosol measurements at sites where the paucity of data is the greatest.

Chemical reactions will change the nature of the deep repository and the surrounding rock (clay rock); that much is certain. But to what extent and with what impact on safety? Researchers from the Paul Scherrer Institute are looking to answer this question with the aid of a combination of experiments and computer simulations.

Superconductivity and magnetic fields are normally seen as rivals – very strong magnetic fields normally destroy the superconducting state. Physicists at the Paul Scherrer Institute have now demonstrated that a novel superconducting state is only created in the material CeCoIn5 when there are strong external magnetic fields. This state can then be manipulated by modifying the field direction. The material is already superconducting in weaker fields, too. In strong fields, however, an additional second superconducting state is created which means that there are two different superconducting states at the same time in the same material.

As part of the Energy Strategy 2050 the Swiss government and parliament have decided to increase support for energy research in Switzerland. This includes the setting up of seven interuniversity networked Swiss Competence Centres in Energy Research (SCCERs). In the SCCERs ETH Domain institutions, the universities and the universities of the applied sciences are to join forces with industrial partners to develop new competencies and solutions in the decisive action areas of the shift in energy policy. The Paul Scherrer Institute PSI will act as the leading house in two of the SCCERs – storage and biomass – that have already been given the green light. They will begin their work in 2014.

Thanks to the analysis of protein samples at the PSI, Lausanne researchers have managed to demonstrate which instrument bacteria use to transmit diseases
Researchers from ETH Lausanne EPFL have described how a particular strain of bacteria transmits diseases with unprecedented precision. The team of scientists headed by Petr Leiman, an assistant professor at the EPFL’s Laboratory of Structural Biology and Biophysics, demonstrated that the tip of a bacterial infection tool consists of a PAAR protein, which envelops a metal atom and tapers off to a sharp point. The findings are based on measurements carried out at the Swiss Light Source (SLS), one of the three large-scale research facilities at the Paul Scherrer Institute (PSI).

A novel polymer electrolyte membrane from the Paul Scherrer Institute PSI has demonstrated longer durability in a laboratory test than the best commercially available counterparts. The breakthrough was achieved by modifying a reasonably priced plastic film through radiation activation and subsequent attachment of functional constituents via a “grafting” reaction. The modified polymer is not only durable – it could also reduce the membrane production costs by 50 to 80 percent. The membrane could be used in applications such as hydrogen fuel cells or electrolysers for hydrogen production from water.
For parties of 12 persons and over, we offer a free-of-charge tour through our large-scale facilities, and for students we have founded the student laboratory iLab. School classes can visit us free of charge for a day, carry out experiments in the laboratory and then see from the large-scale facilities how the scientific principle studied at iLab is applied in routine research.
