A new open access paper published at the Journal of Applied Crystallography (link) describes an integrated indirect Fourier transform/simulated annealing method that exploits the information content of multiple solvent contrast neutron reflectivity data, that permits the model-independent recovery of interfacial structure at the air/liquid and solid/liquid interface. The related software (dionysia) requires as input experimental neutron reflectivity curves and the basic parameters of the experiment (like the scattering length density substrate and solvent), while providing as output, the scattering length density and hydration (solvent volume fraction) profiles at the interface, without the need for any additional information. Feedback and comments for future improvements from potential users will be appreciated! It is a pleasure to invite students interested in Biophysics of biological membranes and neutron scattering to the SINE2020 supported school that I organise together with Dr. Chris Garvey this summer in Garching (near Munich), with the title "Neutrons for membrane biophysics". Registration will be open in the start of April through this web site: www.fz-juelich.de/jcns/SINE2020" Topics that will be covered include small angle scattering, neutron reflectometry, GISANS, lamellar diffraction, molecular deuteration and molecular dynamics in relation to model biomembrane systems.
A team lead by scientists at the Ludwig-Maximilians-Universität in Munich, performed neutron reflectivity measurements at MARIA and REFSANS instruments, that shed light at the interfacial adhesion layer between living cells and hydrophilic surfaces. The related work was recently published at the Langmuir journal (https://pubs.acs.org/doi/full/10.1021/acs.langmuir.8b02228).
Check out the book chapter on "Scattering applications in Life Sciences" co-written with Dr. Andreas Stadler, for the upcoming 50th IFF Spring School - Scattering! Soft, Functional and Quantum Material (Forschungszentrum Jülich GmbH).
