LNS: Laboratory for Neutron Scattering and Imaging

The Laboratory for Neutron Scattering and Imaging (LNS) at the Paul Scherrer Institute is responsible for the scientific exploitation, operation and development of neutron scattering and imaging instruments at the Swiss Spallation Neutron Source (SINQ). The team of 50 senior scientists, postdoctoral researchers and PhD students further collaborates on diverse research projects ranging from modern topics in condensed matter physics and materials science to pressing questions in energy research and health care. read more

Congratulations to PD Dr. Urs Gasser!

Urs Gasser submitted his habilitation at the University of Konstanz last year and held his inaugural lecture 31st May 2016. Now two of the senior members of LNS are teaching in Konstanz. Urs is responsible for the small angle instrument SANS-II at SINQ and his research focuses on fundamental aspects in soft condensed matter physics, in particular the rich behavior of polymers and colloidal suspensions.

The role of ions in the self-healing behavior of soft particle suspensions

A. Scotti et al., Proceedings of the National Academy of Sciences, 1516011113 (2016). Understanding when a material crystallizes is of fundamental importance in condensed matter. In many materials, the presence of point defects suppresses crystallization. Surprisingly, colloidal hydrogels can overcome this limitation: A small number of large microgels can spontaneously deswell to fit in the crystal lattice of smaller microgels, thus avoiding the occurrence of point defects. We find that this unique particle deswelling is due to an osmotic pressure difference between the inside and the outside of the microgels resulting from the overlap of counterion clouds of neighboring particles. When this pressure difference exceeds the bulk modulus of the large microgels, these shrink, enabling crystallization without point defects.
