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. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor

   University essay from Linköpings universitet/Kemi

   Author : Peggy Bagherzadeh; [2023]
   Keywords : Vapor deposition; CVD; ALD; triazenide;

   Abstract : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. READ MORE

4. 8. Tuning electrolyte-electrode interphases for low-temperature Li-ion batteries

   University essay from Uppsala universitet/Strukturkemi

   Author : Robin Xu; [2023]
   Keywords : Li-ion batteries; Low temperature;

   Abstract : Lithium ion batteries (LIBs) are crucial for modern electronics and electric vehicles (EV). However,their electrochemical performance is facing challenges at low temperatures (e.g ≤ 0 °C) due to reducedLi+ kinetics and increased charge-transfer resistance. READ MORE

5. 9. Exploring Particulate Filtration during Thermal Runaway in Lithium-Ion Battery Packs

   University essay from KTH/Kemiteknik

   Author : Amanda Halvarsson; [2023]
   Keywords : battery pack; particles; thermal runaway; filtration; batteripack; partiklar; termisk rusning; filtrering;

   Abstract : Med övergången till elektrifiering inom transport uppstår nya utmaningar när det gäller batterisystem som placeras i elfordon. Det finns för närvarande en möjlighet att minska riskerna med toxiciteten hos partiklar som sprutas ut med de gaser som bildas under termisk rusning i litiumjonbattericeller som är placerade i batterisystem.

6. 10. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Morgan Eliasson; [2023]
   Keywords : Paleolimnology; Lake sediment; XRF; Garpenberg; Mining history;

   Abstract : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. READ MORE
