  1. 1. Manufacturing batteries of the future : Critical challenges and undertakings to create the next generation energy storage

    Kandidat-uppsats, KTH/Produktionsutveckling

    Författare :Victor Carlsson; Victor Granat; [2023]
    Nyckelord :;

    Sammanfattning : In today's world, a dominating piece of news is the global race for large-scale production of Lithium-ion batteries (LIB). LIBs are important because they have become the most widely used type of rechargeable battery in modern electronic devices, such as smartphones, laptops, energy storage systems, and electric vehicles.

  3. 2. The role of marketing to avoid product returns in online shopping : how marketers help online consumers to make better purchase decisions and thus avoid product returns

    Master-uppsats, SLU/Dept. of Economics

    Författare :Mohamad Saad El Deen; [2023]
    Nyckelord :E-commerce; high products return; digital marketing; consumer decision journey; avoid products returns;

    Sammanfattning : The increasing alarm about global climate change and the related consequences on the planet and humankind has raised the voices to adopt sustainability within organisations and businesses. The wide spread of the internet and smart devices allowed many consumers to buy their needs through smart devices without the need to travel to physical stores. LÄS MER

  4. 3. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Sofie Johannesson; Sebastian Skog; [2022]
    Nyckelord :Vertical InGaAs Nanowire MOSFET Temperature Dependence Noise; Technology and Engineering;

    Sammanfattning : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).

  5. 4. Simulations of current transport phenomena in ferroelectric tunnel junctions

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Ivan Lubar; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Ferroelectric memories pose as a potential candidate as resistive memory devices that could be used for in-memory computing and artificial synapses. One promising type of ferroelectric memory device is the ferroelectric tunnel junction (FTJ). LÄS MER

  7. 5. Fjärrkyla på LKAB : Absorptionskylmaskiner, frikyla och dess begränsningar

    Kandidat-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Erik Kruukka; [2020]
    Nyckelord :LKAB; Absorption cooling; District cooling; Free cooling; Heat exchanger; LKAB; Absorptions kyla; Fjärrkyla; Frikyla; Värmeväxlare;

    Sammanfattning : LKAB behöver kyla till sina processer för att kunna förädla järnmalm. Ökad tillgång på elektronik och efterfrågan på komfortkyla breder ut sig i samhället idag, vilket leder till ett ökat kylbehov. Flertalet gamla kylanläggningar på LKAB i Kiruna börjar uppnå sin livslängd och behöver ersättas med nya maskiner och ny teknik. LÄS MER
