Advanced Neutron Tools for Soft and Bio Materials JRA - latest achievements

It is time for a summary of the achievements of this JRA, which aims to provide a wider range of experimental tools to make the best use of neutron scattering for soft and bio-materials.

, 25/09/2015

Neutron techniques, especially neutron reflectivity, have recently offered high performance tools for the study of biological membranes. A great challenge for the future in the field is to succeed in standard production of model membranes, of recipes for specific deuteration and in the development of novel modelling methodology, including molecular scale information from MD simulations for the interpretation of neutron data.

This Joint Research Activity is developing a platform for model biological membranes, soft-material-specific sample environments and in-situ devices. The objective is to provide a wider range of experimental tools enabling to make the best use of neutron scattering for Soft and Bio-Materials, which have many possible applications in the areas of environment, energy and health.

New humidity chamber will shed light on processes behind Alzheimer’s disease

A JRA supported by NMI3 is working on a new humidity chamber. The instrument will be used for neutron scattering experiments to reproduce the human body conditions in order to shed light on biological processes such as the development of Alzheimer’s disease. Check out our video and article here !

Improving neutron scattering data quality: a multi-angle light scattering setup

During a neutron scattering experiment the sample might degrade and produce wrong results. In our new video, researchers explain their work on a set up to control the sample quality along time so that false data can be discarded. This work will improve the data quality.
