1. 11. Novel Hybrid Nanomaterials : Combining Mesoporous Magnesium Carbonate with Metal-Organic Frameworks

   University essay from Uppsala universitet/Nanoteknologi och funktionella material

   Author : Viktor Sanderyd; [2018]
   Keywords : Nanomaterials; Metal-Organic Frameworks; MOF; MMC; Porous; Mesoporous; Upsalite; Hybrid materials; Core-shell;

   Abstract : Nanotechnology as a field has the potential to answer some of the major challenges that mankind faces in regards to environmental sustainability, energy generation and health care. Though, solutions to these concerns can not necessarily rely on our current knowhow. READ MORE

3. 12. Consequences of Magnetic Properties in Stainless Steel for a High-efficiency Wave Power Generator

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Mohamed Sheikh Abdi; Yosef Gebresilassie; [2018]
   Keywords : stainless steel; wave power; permeability;

   Abstract : A new kind of wave power generator is being developed at KTH Royal Institute of Technology which potentially can reach an efficiency of 98 %. However, this generator’s small air gap sets strict requirements on the stiffness of the structure to withstand the large magnetic forces. The structure, therefore, need to be both stiff and non-magnetic. READ MORE

4. 13. Bicomponent Fiber in Sound Absorbent Production : Investigation of using bicomponent fiber as adhesive between woven and nonwoven textile and how it affects the sound absorption

   University essay from Högskolan i Borås/Institutionen Textilhögskolan

   Author : KATARINA LINDSTRÖM; [2014]
   Keywords : Bicomponent fiber; sound absorbent; impedance tube; nonwoven; adhesion strength; air permeability; transfer function method.;

   Abstract : A new way of adhering woven textile to a nonwoven backing was explored, the end product in mind being a sound absorbent panel. Today a hot melt adhesive is sprayed on the nonwoven with woven decorating textile put on top before compression molding. READ MORE

5. 14. Nanocellulose in pigment coatings : Aspects of barrier properties and printability in offset

   University essay from Institutionen för fysik, kemi och biologi

   Author : Sofie Nygårds; [2011]
   Keywords : Nanocellulose; Microfibrillated cellulose; Coatings; Barrier; Printability; Air permeability; Offset; Surface Energy;

   Abstract : Papers are coated in order to improve the properties of the surface, to improve printability and to include new functionalities like barriers properties. Typical coating formulation contains a high number of components, some are made from minerals and others are manufactured from petroleum. READ MORE

6. 15. Performance analysis of Air GapMembrane Distillation:Comparison of PTFE membranes : Comparison of PTFE membranes

   University essay from KTH/Kraft- och värmeteknologi

   Author : Daniel Baaklini; [2011]
   Keywords : Membrane distillation; air gap; flux; PTFE; backing; morphology; performance; Gurley;

   Abstract : Membrane Distillation (MD) is a very promising new technology which can be coupled with renewableenergies and/or waste heat to produce pure water at a low-cost. MD is extremely dependent upon theperformance of the membrane, as it dictates the mass transfer, the heat transfer and the long-termapplication. READ MORE
