Matter and Material

bi2009m06 psi luftbild sls tn.jpg

The manifold characteristics of the matter making up the world around us are determined by what kinds of atoms they are made of, how these atoms are arranged, and how they move. Most researchers in the “Matter and Material” field at the Paul Scherrer Institute are trying to clarify the link between the internal structure and the observable properties of various materials. Researchers in the Laboratory for Particle Physics investigate the structure and properties of elementary particles – the smallest building blocks of matter –and are therefore addressing questions about the basic structures of the world.

Moving Monopoles Caught on Camera

Media Releases Matter and Material Materials Research Micro- and Nanotechnology Research Using Synchrotron Light

For decades researchers have searched for magnetic monopoles à isolated magnetic charges that can move freely like electric charges. Now a team of researchers from the Paul Scherrer Institute and University College Dublin have been able to produce monopoles in the form of quasiparticles in an assembly of nanoscale magnets and have directly observed how they move.

A possible new career for a vital biomolecule

Media Releases Matter and Material Micro- and Nanotechnology Materials Research

As a component of the haemoglobin molecule, porphyrin enables the transport of oxygen within the human body. In a slightly altered form, it may find also applications in technical devices. Researchers at the Paul Scherrer Institute and the University of Basel have shown that a magnetic property of the molecule can be switched on and off by means of a simple chemical procedure, so that the molecule can be used as a tiny molecular switch.

Researchers Find Universal Law For Material Evolution

Media Releases Matter and Material Materials Research Research Using Synchrotron Light

Many important materials are composed of several phases. When such a material is heated, atoms move from one phase to another, which changes the distribution of the phases à and thus, the properties of the material. A team of researchers has now shown that for an important case, there is a general law describing this process that is valid for all classes of materials.

Understanding plastic semiconductors better

Media Releases Matter and Material Materials Research Research Using Synchrotron Light

Semiconductors made from polymer materials are becoming increasingly important for the electronics industry à as a basis for transistors, solar cells or LEDs. Usually, they consist of more than one substance as they get their particular electric properties only when several materials are blended. Researchers from the Paul Scherrer Institute and the University of Cambridge have developed a method that allows them to determine the detailed structure of the material.

Protons - smaller than we thought

Media Releases Matter and Material Research with muons Particle physics

The proton à one of the smallest building-blocks of all matter à is even smaller than had previously been assumed. This discovery is the result of experiments carried out at the Paul Scherrer Institute (PSI) in Villigen, Switzerland, by an international research team.

Technology from the Paul Scherrer Institute detects proton collisions at unprecedented levels of energy

Media Releases Particle physics Matter and Material

CERN has been able to take the first measurements of collisions between the highest-energy particles ever generated. These collisions were performed at CERN's new LHC accelerator and recorded with the CMS Experiment, which involved a key component (the barrel pixel detector) contributed by the Paul Scherrer Institute in collaboration with Swiss Universities. The first LHC operation in Dezember 2009 has now resulted in a first particle physics publications of the CMS experiment. This is after a remarkable short time , given the compexity and the size of this gigantic experiment with over 3000 physicists and engineers from close to 40 countries.

Magnetspeicher der neusten Generation sind 100 000 mal schneller als herkömmliche Festplatten

Media Releases Materials Research Research Using Synchrotron Light Matter and Material

Computer-Festplatten könnten bald ausgedient haben: Forscher des Paul Scherrer Instituts PSI und der Universität Konstanz haben neuartige Magnetbänder untersucht und gezeigt, dass sie nicht nur sehr hohe Speicherdichten, sondern auch viel schnellere Zugriffszeiten als heutige Speichermedien zulassen. Leiter der Studie war Mathias Kläui, der am 1. April eine von der ETH Lausanne und dem PSI gemeinsam finanzierte Professur antritt.This news release is only available in French and German.

Service to the scientific community

Particle physics Matter and Material Large Research Facilities Research Using Synchrotron Light Research Using Neutrons Research with muons

Neutrons, synchrotron light and muons are very useful for researchers in a variety of disciplines. Using these probes, we can determine the structure of crystals, they help us understand magnetic processes, or they can reveal the structures of biological materials. However, producing these probes is so difficult that most research groups will not have a neutron, muon or synchrotron light at their own scientific centre.
