  2. 6. Wear characteristics of materials for artificial hip joints

    Author : Mohammed Seyed Hoseini Nazari; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HDPE; UHMWPE; Coating; Tribology; Pin-on-disc; Y-irradiation; Vitamin E; Wear; Implant; Artificial hip joint;

    Abstract : 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. READ MORE

  4. 7. Designed from Recycled: Microwave-Assisted Upcycling of Plastic Waste

    Author : Eva Bäckström; Minna Hakkarainen; Karin Odelius; Antal Boldizar; KTH; []
    Keywords : Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : 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. READ MORE

  5. 8. Diffusion, Swelling and Mechanical Properties of Polymers

    Author : Janis Ritums; KTH; []
    Keywords : diffusion; swelling; mechanical properties; polymers;

    Abstract : 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. READ MORE

  6. 9. Improved Environmental Performance of Products: Halocarbon Substitution, Packaging Development and Life Cycle Assessment

    Author : Tomas Rydberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  7. 10. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Author : Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Abstract : 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. READ MORE
