1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. LÄS MER
2. Spin-Glass Behaviour in Ordered Solids
Kandidat-uppsats, Uppsala universitet/MaterialteoriSammanfattning : The spin-glass is a peculiar magnetic phase, exhibiting non-trivial dynamics at low temperatures, characterized by an continuously evolving state without long-range order. The behavior requires some degree of disorder to occur, often in the way of impurities or random exchange energy between the spins. LÄS MER
3. Vindstabilisering av SIPS byggnader i Sverige
M1-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)Sammanfattning : Detta arbete handlar om vindstabilisering av en SIPS byggnad i Sverige där fokuset ligger påhur infästningar sker mellan grundplattan och väggarna. SIPS (Structural insulated panels) ärett bärande isoleringselement som används för att bygga hela byggnadskalet. LÄS MER
4. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER
5. 3D Knit fabrics : optimizing spacer knit fabrics for comfort and breathability in infant products
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : In this study we looked into an existing textile baby stroller seat and investigated whether there can be any advantage in changing the material to a spacer fabric from perspectives such as functionality, comfort, and sustainability. The subject of 3D knitting, and advanced knitting is being researched more and more because of its versatility in producing and changing parameters of knitted high quality products, but there is a lack of studies done on comfort for children when it comes to knitted spacer fabrics and not many studies have been done on spacer fabrics used for baby seats in strollers or other types of seats for children.
