6. June 2013Energy and Environment Research Using Neutrons Nuclear Power Plant Safety
Neutrons are an excellent tool for the non-destructive imaging the interior of objects. They can provide a valuable complement to the more widely used x ray radiography. For some materials that are virtually opaque or for those that cannot be distinguished by X-rays, neutrons provide the only informative ‘dissection tool‘. However, neutron radiography is mainly confined to the laboratory and fixed facilities, because neutron generation relies on equipment like nuclear reactors or particle accelerators, which are costly, complex and cannot be moved. Scientists at the Laboratory for Thermohydraulics at the Paul Scherrer Institute PSI want to develop a more flexible imaging technique based on fast neutrons.

The life cycle inventory database ecoinvent forms the basis for life cycle assessment projects, eco-design, and product environmental information. Since 2003, ecoinvent has enabled companies to manufacture their products more in harmony with the environment, policymakers to implement new policies, and consumers to adopt more environmentally friendly behaviour. The new version 3.0 is a further milestone in life cycle assessment: new and updated data offer ecoinvent users a greater number of possible applications in the areas of e.g. chemical production, foodstuffs, vegetables and electricity.

Household waste always used to end up left untreated in landfills, and the effects of this practice are well-known: these waste disposal sites were quite often ecological "death zones". With the incineration of municipal waste, there was some mitigation of this problem: despite the overall increase in quantities of waste, the areas claimed by landfill have been limited in recent decades thanks to waste recycling and incineration. However, waste incineration remains far from a panacea. Some combustion products that are already present in the burnt materials or that arise just during the combustion process itself are harmful to human health and the environment and some of them still find their way out of waste incineration plants and into landfill sites as their final destination.
17. May 2013Matter and Material Large Scale Facilities Research Using Muons
Muons – unstable elementary particles – provide scientists with important insights into the structure of matter. They provide information about processes in modern materials, about the properties of elementary particles and the nature of our physical world. Many muon experiments are only possible at the Paul Scherrer Institute because of the unique intense muon beams available here.

Megacities are often perceived by the public to be major sources of air pollution, which affect their surroundings as well. However, recent studies show that the environmental credentials of cities with over one million inhabitants are not so bad after all. An international team of researchers, including scientists from the Paul Scherrer Institute (PSI), has now confirmed, on the basis of aerosol measurements carried out in Paris, that so-called post-industrial cities affect the air quality of their immediate surroundings far less than might be thought.
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.
