  2. 1. Design and Optimization of CO2 sorbents for Point Source Emissions and Direct Air Capture

    Author : Ribooga Chang; Ocean Cheung; Jean-Francois Boily; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCS; CO2 Sorbents; Direct Air Capture;

    Abstract : This thesis presents a comprehensive study on the design and optimization of CO2 sorbents, targeting two distinct applications: CO2 capture from point source emissions and Direct Air Capture (DAC). The research first introduces Na2HfO3 as a potential CO2 sorbent for point source emissions, using the molten salt effects of Na2CO3 and the thermal stability of HfO2. READ MORE

  4. 2. Antivirulent and antibiofilm salicylidene acylhydrazide complexes in solution and at interfaces

    Author : Shoghik Hakobyan; Madeleine Ramstedt; Jean-Francois Boily; Mikael Elofsson; Marcus Textor; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antivirulent; Antibiofilm; Hydrazones; Gallium; Pseudomonas aeruginosa; Type three secretion system; Equilibrium constant; Chemical equilibrium modelling; Spectrophotometric titration; UV-Vis;

    Abstract : The growing bacterial resistance against antibiotics creates a limitation for using traditional antibiotics and requests development of new approaches for treatment of bacterial infections. Among the bacterial infections that are most difficult to treat, biofilm-associated infections are one of the most hazardous. READ MORE

  5. 3. Surface reactions of magnetite and maghemite with dissolved and added ions in process water

    Author : Rickard Jolsterå; Jean-Francois Boily; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Reactions between mineral surfaces and dissolved species in process water, both inorganic and organic play an important role in mineral processing. Reverse flotation of finely comminuted iron ore is sometimes employed in order to remove the phosphorous mineral apatite. READ MORE

  6. 4. Charge Development at Iron Oxyhydroxide Surfaces : The Interplay between Surface Structure, Particle Morphology and Counterion Identity

    Author : Philipp A. Kozin; Jean-François Boily; Michael Kersten; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Iron oxyhydroxides; adsorption; mineral-water interface; electrolyte; surface roughness; pores;

    Abstract : Iron (oxyhydr)oxide (FeOOH) minerals play important roles in various natural, technological and societal settings. The widespread abundance of these minerals has prompted numerous studies on their surface reactivity in aqueous media. Surface charge development, one that namely takes place through the adsorption of potential determining ions (p.d. READ MORE

  7. 5. Molecular-level controls on water and organics intercalation in layered minerals

    Author : Jerry Lindholm; Michael Holmboe; Jean-Francois Boily; Virginie Marry; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Minerals; Dynamic Vapor Sorption; montmorillonite; XRD; adsorption model; intercalation;

    Abstract : Layered minerals are naturally abundant and often display a large surface area in relation to their weight. For swelling layered minerals, most of this area is contained between the layers in the interlayer space. READ MORE
