1. 1. 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. 2. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Zahra Mohammadianrasnani; [2023]
   Keywords : GaN; Sputter epitaxy; Thin film;

   Abstract : In this study, the effect of AlN buffer layer structure and morphology on the GaN films deposited on Si (111) substrate by reactive DC magnetron sputtering have been studied. For structural and morphological characterization X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used. READ MORE

4. 3. Cellulose oxalates in biocomposites

   University essay from KTH/Fiber- och polymerteknologi

   Author : Jiarong Liang; [2021]
   Keywords : cellulose; cellulose oxalate; compatibilizer; composite; mechanical properties; polypropylene; cellulosa; cellulosaoxalat; kompatibiliseringsmedel; komposit; mekaniska egenskaper; polypropylen;

   Abstract : Under de senaste åren, på grund av överanvändningen av icke förnybara resurser har den ekologiska miljön på jorden påverkats allvarligt. I takt med detta ökade oron bland människor om att resurserna skulle ta slut. Därför är det nödvändigt att utveckla och använda mer miljövänliga förnybara resurser. READ MORE

5. 4. Chemical modification of regenerated-cellulose films with determined patterns and different regeneration mediums to achieve superhydrophobic properties

   University essay from Mittuniversitetet/Institutionen för kemiteknik

   Author : Pornpan Kongthong; [2021]
   Keywords : Surface roughness; regeneration of cellulose; Regenerated-cellulose; superhydrophobic surfaces; Alkyl Ketene Dimer AKD ; Scanning Electron Microscope SEM and X-Ray diffraction XRD ;

   Abstract : In our modern society there is a need to find a material that is biodegradable to reduce the use of plastic for a greener society. By means of superhydrophobic surfaces there is a possibility to replace plastic with cellulose and use Alkyl Ketene Dimer (AKD) as a sizing agent to make the surface hydrophobic. READ MORE

6. 5. Preparation and Characteristics of Bi0.5Na0.5TiO3 based Lead-Free thin films by Pulsed Laser Deposition

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Ge Jiang; [2018]
   Keywords : PLD method; piezoelectric thin film; electrical properties; PLD-metoden; piezoelektrisk tunnfilm; elektriska egenskaper;

   Abstract : Lead-based piezoelectric materials, such as PbZrxTi1-xO3 (PZT), have attracted considerable attention and have been widely used in actuators, sensors and transducers due to their excellent electric properties. However, considering the toxicity of lead and its oxides, environmentally friendly lead-free piezoelectric materials are attracting more attention as potential replacements for PZT. READ MORE
