  1. 1. Synthesis of Graphene - Carbon Nanotube Hybrid Structures

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Aniruddha Paul; [2021]
    Keywords : Graphene; Carbon nanotubes; Graphene-CNT hybrid structures; Chemical Vapor Deposition CVD ; Grafen; Kolnanorör; Grafen-CNT-hybridstrukturer; Kemisk ångdeposition CVD ;

    Abstract : Graphene and Carbon nanotubes (CNTs) have been researched for more than a decade due to their extraordinary properties and advantages towards applications like electronics, structural re-enforcements, thermal management and energy storage. Graphene-CNT hybrid structures have been predicted to further enhance the exceptional properties and overcome some of the shortcomings of the individual materials. READ MORE

  3. 2. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Cecilia Nemeth; [2020]
    Keywords : high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

    Abstract : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. READ MORE

  4. 3. Comparative study of three Fe (III)-ion reducing bacteria gives insights into bioelectricity generation in the MFC technique

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Joyanto Mahato; [2020]
    Keywords : Microbial fuel cell; biocatalysts; electron transfer mechanism; gene network; domain composition;

    Abstract : Microbial fuel cell (MFC) technology is a renewable energy source that employs microorganisms as biocatalysts to degrade substrates into electrons and protons, and then transfer the electrons to the anode electrode. Electron transfer rates by microorganisms depend on many factors as well as on their diverse electron transfer mechanisms. READ MORE

  5. 4. An investigation of friction graphs ranking ability regarding the galling phenomenon in dry SOFS contact : (Adhesive material transfere and friction)

    University essay from Karlstads universitet/Fakulteten för teknik- och naturvetenskap

    Author : Harald Wallin; [2008]
    Keywords : galling; friction; adhesive contact; mild adhesive; severe adhesive; abrasive; flattening; SOFS; TNO; slider on flat surface; tribology; dry; lubricated; frictional heating; acceleration; plastic zone; contact pressure; pressure; phase transformation; morphology; seizure; scoring; scuffing; cohesive forces; classification; characteristic patterns; lump; sheet damage; på kletning; friction; kontakt tryck; värme; plogning;

    Abstract : The main purpose of this project is to investigate different tool steels in terms of their ability to withstand material transfer buildup, so-called galling, occurring in SMF (sheet metal forming) operations. The ability to withstand galling is vital to optimize cost-effectiveness and increase the work tool’s effective operational time. READ MORE
