  1. 21. Marketing Introduction Plan for the New Generation of Sustainable Circuit Breakers LTA 420 kV : A real-life case for implementation at Hitachi ABB Power Grids

    University essay from KTH/Kemiteknik

    Author : Ivan Fradinho Bastos; [2021]
    Keywords : high-voltage circuit breaker; SF6-free circuit breaker; sustainable circuit breaker; eco-efficient high-voltage circuit breaker; market introduction plan; högspänningsbrytare; SF6-fri strömbrytare; hållbar strömbrytare; miljöeffektiv högspänningsbrytare; marknadsintroduktionsplan;

    Abstract : En strömbrytare är en säkerhetsanordning som är utformad för att bryta strömmen om ett problem uppstår. Det finns ett flertal olika typer av brytare beroende vilket spänningsområde som avses. Brytare för lågspänning används för hushållsapparater, medan högspänningstyper används för överföring av spänning i elnätet. READ MORE

  3. 22. Environmental transformations of Manganese and Manganese oxide nanoparticles

    University essay from KTH/Materialvetenskap

    Author : Lundberg Annie; [2020]
    Keywords : ;

    Abstract : Engineered nanoparticles (NPs) are produced in increased quantities. Due to this increase, itis vital to understand the full lifecycle and fate of these NPs to prevent any possible environmental stress. READ MORE

  4. 23. Impact of different catchments on the Brownification of Lake Bolmen

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Kaela Chileshe; [2020]
    Keywords : Brownification; dissolved organic carbon DOC ; Iron Fe ; water colour; landscapes; climate change;

    Abstract : Increased DOC and Fe concentrations from terrestrial landscapes has led to the browning of boreal surface waters. The negative societal and ecological impacts of brownification are increased cost of water purification, increased presences of algae and cyanobacteria, loss of ecosystem services and reduced recreational value.

  5. 24. Sputtering of High Quality Layered MoS2 films

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Sari Abid Al Shaybany; [2020]
    Keywords : MoS2; molybdenum; molybdenum disulfide; sputtering; magnetron sputtering; high quality; sulfur; H2S; argon; pressure; temperature; high temperature; monolayer; few layers; large scale;

    Abstract : We have deposited bulk, monolayer and few-layers as well as large-scale 2D layered MoS2 thin films by pulsed DC magnetron sputtering from an MoS2 target. MoS2 has gained great attention lately, together with other layered Transition Metal Dichalcogenides (TMDCs), for its unique optical and electrical properties with thickness-dependent bandgap.

  6. 25. Towards a better understanding of protein structures : assessing the sulfur bridge in Cystine through photofragmentation

    University essay from Uppsala universitet/Materialteori

    Author : Emma Danielsson; [2020]
    Keywords : biophysics; python; simulation;

    Abstract : This work aims to investigate the fragmentation of an ionized Cystine molecule, as simulated in the framework of molecular dynamics and quantum mechanics. Cystine is viewed as a model system for larger sets of peptides -- ultimately contributing to the understanding of protein photofragmentation, which is crucial for determining the structure of a protein using new methods.
