  1. 6. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

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

    Author : Abderrahim Ait ouakrim; [2023]
    Keywords : Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

    Abstract : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

  3. 7. Biodiesel production from rape seed oil catalyzed by calcium oxide doped with lithium

    University essay from KTH/Kemiteknik

    Author : Abdulbasit Abdalla; Emilia Odgren; [2023]
    Keywords : Biodiesel; transesterifiering; FFA; glycerol; FAME; förtvålningsreaktion; Li-CaO; BET; EDS; SEM; heterogena katalysatorer; utbyte; kinetik;

    Abstract : Biodiesel ses som ett av de främsta substituten för fossila bränslen, då den relativt enkelt kan appliceras i redan existerande dieselmotorer. Dagens produktion av biodiesel använder sig av homogena katalysatorer som inte återanvänds i processen, men för en mer cirkulär och i längden en billigare process ses heterogena katalysatorer som ett alternativ.

  4. 8. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

    University essay from KTH/Materialvetenskap

    Author : Ratna Juwita; [2023]
    Keywords : Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

    Abstract : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. READ MORE

  5. 9. Silicon Drift Detector Simulations for Energy-Dispersive X-ray Spectroscopy in Scanning Electron Microscopy

    University essay from Stockholms universitet/Fysikum

    Author : Sebbe Blokhuizen; [2023]
    Keywords : X-ray spectroscopy; Silicon drift detector; Scanning Electron Microscopy; Detector Simulation;

    Abstract : Scanning Electron Microscopy combined with Energy Dispersive X-ray Spectroscopy (SEM-EDS) is a widely applied elemental microanalysis method. The integration of silicon drift detectors (SDDs) has notably enhanced EDS performance, enabling precise elemental identification due to its large sensitive area and low output capacitance.

  6. 10. Particulate matter analysis from engine outlet in heavy-duty diesel vehicles : A study of soot reactivity, morphology and ash-to-soot ratio from the outlet of 6-cylinder and 8-cylinder diesel engines.

    University essay from KTH/Kemiteknik

    Author : Tayisiya Vlasenko; [2023]
    Keywords : Diesel engine; particulate matter; kinetics; soot; heavy-duty vehicles; Dieselmotor; partiklar; kinetik; sot; tunga fordon;

    Abstract : De ökande luftföroreningarna i Europa är ett allvarligt miljöproblem, och vägtransporterna är en av de största orsakerna till detta. För att ta itu med detta problem och uppfylla nya utsläppskrav måste efterbehandlingssystemen för avgaser förbättras. READ MORE
