  1. 21. Carbon nanofiller reinforced UHMWPE for orthopaedic applications : optimization of manufacturing parameters

    Författare :Evelina Enqvist; Mats Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Polymer composites research designed for orthopaedic applications are commonly focused on Ultra high molecular weight polyethylene (UHMWPE) reinforced by a variety of different nanoparticles. However, the high melt viscosity of UHMWPE renders conventional melt mixing techniques impossible for composite manufacturing. LÄS MER

    Författare :Anders Hansson; Gianaurelio Cuniberti; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular crystals; Organic crystals; Nano technique; Density-Functional Theory DFT ; Fermi; Physics; Fysik;

    Sammanfattning : In the past decade the interest in molecular electronic devices has escalated. The synthesis of molecular crystals has improved, providing single crystals or thin films with mobility comparable with or even higher than amorphous silicon. Their mechanical flexibility admits new types of applications and usage of electronic devices. LÄS MER

  4. 23. 2nd and 3rd generation electrodes for biosensors and biofuel cells

    Författare :MNadeem Zafar; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; WrbA; pyranose dehydrogenase; cellobiose dehydrogenase; glucose dehydrogenase; direct electron transfer; Os-polymers; mediated electron transfer; single-walled carbon nanotubes; amperometric biosensor; biofuel cell; screen-printed electrodes; flow injection analysis; cascade reaction; bioanode;

    Sammanfattning : The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and GDH have a catalytic FAD-containing domains. LÄS MER

  5. 24. Investigation of Carbon Reinforced UHMWPE Nanocomposites for use in Orthopaedics

    Författare :Silvia Suñer Moreno; Robert S Dwyer-Joyce; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : Over the lifetime of a person, the function of the natural hip joint can be altered due to trauma or disease and an artificial hip replacement may eventually be required. Ultra high molecular weight polyethylene (UHMWPE) is considered the gold standard material for the acetabular cup in hip arthroplasties. LÄS MER

  7. 25. Modeling nanofiber transport and deposition in human airways

    Författare :Sofie Högberg; Geoff Gibson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : An understanding of the complex motion of fibrous particles is important in a wide range of areas, including inhalation toxicology, targeted drug delivery, composites manufacturing, paper making, and food processing. While the applications are diverse, the governing equations for the fiber motion may be shared. LÄS MER
