1. On the Electrolyte Induced Aggregation of Concentrated Silica Dispersions - An Experimental Investigation Using the Electrospray Technique
Sammanfattning : Gels are weak, solid-like structures that arise when colloidal particles aggregate to form a network of particle clusters. A variety of colloidal systems that are important scientifically as well as in industrial applications are capable of gel formation, e.g. globular protein solutions, colloid-polymer mixtures, and metal oxides.

2. Platelet reactivity and comorbidities in acute coronary syndrome
Sammanfattning : Background In the event of an acute coronary syndrome (ACS), the risk of death and complications such as stroke and re-infarction is high during the first month. Diabetes, impaired kidney function, elevated markers of systemic inflammation and high level of platelet reactivity have all been associated with worsened prognosis in ACS patients. LÄS MER
3. Study of particle-current-electrocrystallization interactions in electroplating of Ni/SiC coatings
Sammanfattning : Composite coatings have great potential due to the possibility to combine properties of two different materials in one coating. This way, new surface properties can be tailored and applied to any material's surface. LÄS MER
4. Nano-particulate Silica Hydrogels Imaged in 2D and 3D using TEM: Effects of local pore structure on mass transport and applications in aggregation dynamics
Sammanfattning : Porous materials are frequently used in everyday applications including food science, pharmaceuticals, fuel cell membranes, batteries and solar cells. A key aspect in these porous materials is how their micro- and nano-structure affect the internal transport of for example water, particles or charges. The transport is a three-dimensional process.

5. Biomass to Biofuel : Syngas Cleaning and Biomass Feedstock
Sammanfattning : This thesis builds around the idea of a biofuel production process that is comprised of biomass production, biomass gasification, gas cleaning, and fuel production. In this work, we specifically looked into H2S removal as a part of cleaning the producer gas and flocculation of microalgae which is involved in the harvesting of microalgae after biomass production.
