1. Optimization of Electron Beam Melting for Production of Small Components in Biocompatible Titanium Grades
Abstract : Additive manufacturing (AM), also called 3D-printing, are technologies where parts are formed from the bottom up by adding material layer-by-layer on top of each other. Electron Beam Melting (EBM) is an AM technique capable of manufacturing fully solid metallic parts, using a high-intensity electron beam to melt powder particles in layers to form finished components.

2. Surface characterisation of thermally modified spruce wood and influence of water vapour sorption
Abstract : Today there is growing interest within the construction sector to increase the proportion of biobased building materials made from renewable resources. By-products or residuals from wood processing could in this case be valuable resources for manufacturing new types of biocomposites. READ MORE

4. Amphiphilic Polymers as Additives in Biomedical Polyurethanes. Surface Properties and Morphology
Abstract : The aim of this work was to achieve surface modification of two biomedical polyurethanes and one poly(urethane urea) through the addition of small amounts of amphiphilic copolymers in solution. The matrix polymers used were the poly(ether urethane)s Pellethane 2363-80AE (P80) and 2363-75D (P75) and a poly(ether urethane urea) similar to Biomer (PUUR). READ MORE

5. Controlled Degradation of Polyester-Ethers Revealed by Mass Spectrometry Techniques
Abstract : The use of degradable biomedical materials in e.g. tissue engineering and controlled drug delivery has changed medical science during recent decades. The key question is to adapt the material with respect to mechanical properties, surface characteristics, and degradation profile to suit its intended application. READ MORE
