  1. 1. The evidence base of elevated vacuum and pin-lock suspension system in transtibial prosthetic users: A literature review with a systematic approach

    University essay from Jönköping University/HHJ. Ortopedteknisk plattform

    Author : Louise Dömstedt; Malin Stafås; [2022]
    Keywords : transtibial prosthetics; transtibial suspension method; elevated vacuum; active vacuum; pin-lock;

    Abstract : Aim: This review aims to describe the existing evidence base for using elevated vacuum suspension and pin-lock suspension systems in regards to fluctuations of limb volume, balance, effect on gait (spatial and temporal, kinematic, and kinetic data), and in-socket movement (pistoning and transverse forces). Background: There is a growing population with a TT amputation thus there is an increased demand for TT prosthetic solutions. READ MORE

  3. 2. Water assisted CO intercalation underneath Ir(111) supported graphene studied with scanning tunneling microscopy

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Kaivalya Mevada; [2018]
    Keywords : Graphene; Intercalation; STM; CVD; TPG; Physics and Astronomy;

    Abstract : Graphene have attracted attention recently due to its unique properties and opportunities for development of high performance carbon based devices. The intercalation, absorption and reactions processes of small molecules above and below the graphene islands hold the key for new perspectives in catalysis, molecular sensors and other technologies.

    Author : Vidar Flodgren; [2017]
    Keywords : nanoscience; physics; quantum dots; electron transport; Physics and Astronomy;

    Abstract : In this bachelor project, the electron transport within quantum dot transistor devices, whose barriers are electrostatically induced, was measured and analysed. The properties of devices with this particular architecture are not yet fully understood. READ MORE

  6. 5. Thermal Stability of Zr-Si-N Nanocomposite Hard Thin Films

    University essay from Nanostrukturerade material

    Author : Nai-Yuan Ku; [2010]
    Keywords : Zr-Si-N films; Nanocomposite hard coatings; Nanostructure; Magnetron sputtering; Hardness; Mechanical property; Thermal stability; Annealing; Transmission electron microscopy; X-ray diffraction; Nanoindentation; Elastic recoil detection analysis;

    Abstract : Mechanical property and thermal stability of Zr-Si-N films of varying silicon contents deposited on Al2O3 (0001) substrates are characterized. All films provided for characterization were deposited by reactive DC magnetron sputter deposition technique from elemental Zr and Si targets in a N2/Ar plasma at 800 oC. READ MORE
