16. Long-term performance of water repellants on rendered autoclaved aerated concrete
Sammanfattning : Many failures of external walls made of porous buildingmaterials are caused by excessive moisture content,particularly after driving rain and under long duration ofmoist conditions. Lack of sufficient protection againstexposure conditions is one of the reasons for external wallsprematurely demonstrating failures, i.e. LÄS MER
17. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents
Sammanfattning : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. LÄS MER
18. Powder degradation during powder bed fusion processing: impact of processing conditions and alloy composition
Sammanfattning : In the recent decade, powder bed fusion (PBF) metal additive manufacturing (AM) has attracted huge attention both from the industry and the research community. This effort has helped mature PBF technology as a potential alternative to conventional manufacturing processes as casting, machining, forging, etc. LÄS MER
19. Covalent Surface Modification of Degradable Polymers for Increased Biocompatibility
Sammanfattning : Degradable polymers have gained an increased attention in the field of biomedical applications over the past decades, for example in tissue engineering. One way of improving the biocompatibility of these polymers is by chemical surface modification, however the risk of degradation during the modification procedure is a limiting factor. LÄS MER
20. A Damage-Based Interface Model: Application to the Degradation and Failure of a Polycrystalline Microstructure
Sammanfattning : A constitutive model for material interfaces is presented. The model is based on damage coupled to plastic (or viscoplastic) slip and dilatation, and it is able to describe the successive degradation and failure of an interface. LÄS MER
