Not a drop too much
The supply of a vapour saturated gas mixture plays a crucial role in many industrial processes. In this way, for example, the emission of nitrogen oxides during diesel combustion can be reduced by ensuring high vapour saturation of the gas mixture. A scientist at the Paul Scherrer Institute has come up with an invention which enables this to be implemented industrially in the future via a simple, flexible and robust technique.
Searching for the Higgs boson: PSI inside
Higgs Particle Found announced the media triumphantly in July 2012. But for Roland Horisberger, particle physicist at PSI, this was a premature conclusion: It will take at least another five years before we can be sure of that. Whatever the findings à whether this is the original Higgs boson, or only one of the theoretical Higgs-like particles à one can surely put a tag on them that reads PSI inside.
Fast neutrons for improved 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.
ecoinvent – The World’s Leading LCA Database Launches Version 3.0
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.
