6. Wear characteristics of materials for artificial hip joints
Sammanfattning : Total hip prostheses have succeeded in significantly improving the quality of life of millions of patients worldwide. Ultra high molecular weight polyethylene (UHMWPE) has been widely and successfully used as a bearing material in orthopaedic prostheses since the 1960s. LÄS MER
7. Designed from Recycled: Microwave-Assisted Upcycling of Plastic Waste
Sammanfattning : Mismanagement of plastic waste is of great concern. To reach a more sustainable society, methodologies to handle materials in a more circular way needs to be developed. LÄS MER
8. Diffusion, Swelling and Mechanical Properties of Polymers
Sammanfattning : Polymers capability to withstand harmful interactions withdifferent environments can be determined by looking at thetransport and mechanical properties of the material exposed tothe medium. The diffusion of a penetrant in a polymer and itsswelling characteristics can be verified by a simplesorption-desorption experiment followed by methodical analysisof the data. LÄS MER
9. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques
Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. LÄS MER
10. Improved Environmental Performance of Products: Halocarbon Substitution, Packaging Development and Life Cycle Assessment
Sammanfattning : Substitution of halocarbons and development of packaging were studied as examples of a product-oriented approach to environmental protection. A contribution to the development of the Life Cycle Assessment (LCA) methodology was made in order to assess the environmental performance of products. LÄS MER
