16. Preparation and characterization of graphene/metal composites
Abstract : Since the isolation of graphene in 2004, much research has been conducted to understand this novel material and how its properties can be utilized in different applications. One type of venture involves graphene as a reinforcing filler in metal matrix composites (MMC) which is becoming increasingly prevalent in the automotive and aerospace industries. READ MORE

17. Engineering Epitaxial Graphene for Quantum Metrology
Abstract : Quantum resistance metrology deals both with the precise and accurate measurement of electrical resistance, by utilizing the quantum hall effect (QHE) in two-dimensional electron gases (2DEGs) such as those based on gallium arsenide (GaAs). Due to the unique properties of graphene, and specifically epitaxial graphene grown on silicon carbide (SiC/G), quantum Hall resistance (QHR) standards based on graphene perform better in a wider parameter space (temperature, current and magnetic field) than conventional semiconducting materials.

18. Paper-based Supercapacitors
Abstract : The growing market of mobile electronic devices, renewable off-grid energy sources and electric vehicles requires high-performance energy storage devices. Rechargeable batteries are usually the first choice due to their high energy density. However, supercapacitors have a higher power density and longer life-time compared to batteries. READ MORE

19. Nano-porous Alumina, a Potential Bone Implant Coating
Abstract : This thesis describes a method of growing a highly adherent nano-porous alumina coating on titanium implant materials, a design which might be useful in hard tissue replacement. Alumina layers were formed by anodisation of aluminium, which had been deposited on titanium and titanium alloys by electron beam evaporation. READ MORE

20. On the influence of biochemical coating on implant bone incorporation
Abstract : Implantat används idag med goda resultat för att ersätta förlorade tänder. Tandimplantat opereras in i käkbenet och agerar som en konstgjord rot för en konstgjord tand eller för att förankra en protes. Implantatens ytor har utvecklas med åren från att vara släta till måttligt råa. READ MORE
