1. Life and fracture in very high cycle fatigue of a high strength steel
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : Classical fatigue models teach that there is an intrinsic fatigue limit for steels, representing a level of stress that is too low for regular crack growth where every cyclic load propagates a fatigue crack through the material. Modern application with extreme lifetimes has shown that fatigue will still take place in steels with stress levels well below the expected fatigue limit. LÄS MER
2. Kan benceller bevaras över miljontals år?
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Termen ’bencell’ omfattar ett antal celltyper som finns i benvävnad hos ryggradsdjur. Från fossil av ryggradsdjur har det beskrivits bevarade mikrostrukturer vars morfologi överensstämmer med den bencellstyp som kallas osteocyter. LÄS MER
3. Bacteria - based self - healing mortar with bio - plastic healing agents : Comparative analysis on quantification and characterization of self-healing by various experimental techniques
Master-uppsats, KTH/BetongbyggnadSammanfattning : Crack formation in concrete structures due to various load and non-load factors leading to degradation of service life is very common. Repair and maintenance operations are, therefore, necessary to prevent cracks propagating and reducing the service life of the structures. LÄS MER
4. Reduction of iron oxide by hydrogen studied using environmental transmission electron microscopy
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : This thesis aims to explore how the reduction of iron oxide by hydrogen should be explored in an environmental transmission electron microscope (ETEM). This is done by performing a series of reduction attempts in the ETEM at nCHREM, Lund University, and exploring how the ETEM conditions are different from those used commercially. LÄS MER
5. Microscopy techniques for studying polymer-polymer blends
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Semiconductors are used in many electronic applications, for example diodes, solar cells and transistors. Typically, semiconductors are inorganic materials, such as silicon and gallium arsenide, but lately more research and development has been devoted to organic semiconductors, for example semiconducting polymers.
