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...
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...
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...
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...
