24. Neutron research, Contr. talk 1 - Residual stress and heat treatment studies of additively manufactured stainless steel by neutron imaging and diffraction

One of the biggest limitations of parts made by Selective Laser Melting (SLM) is the high tensile residual stresses that accumulate in the near-surface region. They are known to have a detrimental effect on mechanical properties and can even cause SLM process failure. Therefore, it is always needing to be applied additional heat treatment operations to relieve stress or shock peening to...

25. Neutron research, Contr. talk 2 - Sucrose versus trehalose as possible preservatives for proteins

Sucrose and trehalose are well-known industrial preservatives for various purposes: they are widely used in cosmetics, food conservation and pharmaceutical industry [1,2]. For instance, sucrose is a stabilizing compound of covid-19 vaccine produced by Pfizer [3]. In this work with the help of atomistic molecular dynamics simulations sucrose and trehalose were considered as agents for...

26. Neutron research, Contr. talk 3 - Na-Ion Dynamics in the Solid Solution Ca1-xNaxCr2O4 Studied by Muon Spin Rotation and Neutron Diffraction

Elisabetta Nocerino (KTH)

Strongly anisotropic and especially one-dimensional or quasi-one-dimensional (Q1D) compounds are gaining increasing attention from the scientific community. In the field of condensed matter physics, 1D magnets have been extensively studied for fundamental research purposes, but recently also for their potential use in spintronic applications. In the area of energy materials, the anisotropic...

27. Neutron research, Contr. talk 4 - Detection of water in cement mortar at room temperature and during freezing

Katja Frid (Malmö University)

Water is present in most of the degradation mechanisms that concrete is exposed to. When these mechanisms are studied experimentally to build models, it is very important that the moisture content in the material is controlled and correct. The aim for the experiment was to study the water and pore distribution in air-entrained cement mortar with varying moisture preconditioning using...

28. Neutron research, Contr. talk 5 - The solution structure of the pentameric ligand-gated ion channel GLIC probed by small-angle neutron scattering

Marie Lycksell (Stockholm University)

10/05/2021, 15:20

Pentameric ligand-gated ion channels undergo subtle conformational cycling to control electrochemical signal transduction in many kingdoms of life. Several crystal structures have now been reported in this family, but the functional relevance of such models remains unclear. We used small-angle neutron scattering (SANS) to probe ambient solution-phase properties of the pH-gated bacterial ion...
