1. 16. Novel steel hinge connection for pedestrian timber bridges : Novel steel hinge connection for pedestrian timber bridges

   University essay from KTH/Byggnadsmaterial

   Author : Charlotte Jaeger; [2023]
   Keywords : ;

   Abstract : This study focuses on exploring a novel timber-to-timber joint using a steel hinge connection (in this work also referred to as door-hinge joint) for pedestrian timber bridges. To conduct the cross-section design of the structural bridge members, a numerical model was developed to determine the internal forces. READ MORE

3. 17. A novel approach for functionalising and separating Tröger's Base Analogues

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Emil Jakobsson; [2023]
   Keywords : Tröger s Base; Synthesis; Chromatography; Supramolecular chemistry; Diastereomers; Organic chemistry; Chemistry;

   Abstract : Tröger’s Base (TB) is a bicyclic compound containing a methanodiazocine group between two aromatic rings. The methylene bridge forces the molecule to have a bent formation; thus, the aromatic rings are close to 90 degrees relative to each other, resulting in a rigid concave aromatic cavity. READ MORE
