1. Tribological Performance of Ferritic Nitrocarburizing (FNC) Treated Automotive Brake Discs
Master-uppsats, Lunds universitet/Industriell ProduktionSammanfattning : The increase of electric vehicles in the market demands the automotive industries to search for better brake disc material with high wear resistance, corrosion resistance, and longer service life. The GCI brake discs, a traditionally used material that has less wear and corrosion resistance. LÄS MER
2. Laser Beam Pathway Design and Evaluation for Dielectric Laser Acceleration
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : After nearly 100 years of particle acceleration, particle accelerator experiments continue providing results within the field of high energy physics. Particle acceleration is used worldwide in practical applications such as radiation therapy and materials science research. Unfortunately, these accelerators are large and expensive. LÄS MER
3. The Magnetic Characterization of Iron-Chrome nanoparticle
Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : In this thesis, the intrinsic magnetic characteristic of 10 nm FeCr oxide nanoparticles is studied. The nanoparticles is produced using the method of Spark discharge generation. Scanning electron microscope (SEM) is used to characterize the size distribution and coverage of deposited particle.

4. Using gallium nitride nanowires as STM probes
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : Gallium nitride (GaN) nanowires grown using catalyst-free metal organic vapor phase epitaxy were used as scanning tunneling microscope (STM) probes. The probes were prepared by placing a GaN nanowire on a tungsten STM probe using a nanomanipulator in a scanning electron microscope (SEM) and welding them together using an electron beam induced platinum deposition.

5. Formation of Soft Particles in Drop-in Fuels
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : As the mission to the decrease global warming and phase out highly pollutingenvironmental practices globally, regulations including Euro 6 and policies generated by theUnited Nations Framework Convention on Climate Change (UNFCCC) are pushing companiesto be more innovative when it comes to their energy sources. These regulations involve manyfactors related to the cleanliness of the fuel and produced emissions, for example, propertiesof the fuels such as sulfur content, ash content, water content, and resulting emission valuesof Carbon dioxide (CO2) and Nitrogen Oxides (NOx).
