  2. 11. Exciton coupling and energy transfer in perylene-based systems

    Author : Alexei Cravcenco; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chemistry; Photophysics; Energy transfer; FRET; Perylene; J-aggregate;

    Abstract : Understanding the nature of photoinduced processes in organic molecules is essential for the design and synthesis of compounds with desired photochemical properties. This dissertation aims for gaining knowledge and mechanistic understanding of energy transfer in perylene-based systems. READ MORE

  4. 12. On the role of actin in yeast protein quality control

    Author : Lisa Larsson Berglund; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein quality control; Actin; Protein aggregate; Segregation; Polarisome; CCT; Huntingtin;

    Abstract : Every cell is equipped with a protein quality control system to ensure the proper function of proteins. This is essential for both cell maintenance and the generation of new and healthy cells. READ MORE

  5. 13. Strong exciton-photon and exciton-exciton coupling and its effects on molecular photophysics

    Author : Yi Yu; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strong coupling; triplet transition dynamics; TADFs; aggregate states;

    Abstract : The energy of molecular states and their transition dynamics form the key properties to understand the photophysics of organic molecules. Strong exciton-photon and exciton-exciton couplings enable the possibility to manipulate these properties without changing the chemical structures. This is due to the formation of new energy states.

  6. 14. A Life Cycle Approach to Environmental Sustainability in Aggregate Production Systems

    Author : Christina Lee; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Aggregates; Gravel; Sand; LCA; Production Systems; Sustainability; Life Cycle Assessment; Environmental Management; EPDs; Quarries; Tool Development; Environmental Impact; Environmental Product Declarations; Construction Products;

    Abstract : Rock materials, such as sand, gravel, and crushed rock, serve as the foundation of our society. Known collectively as aggregates, these materials are essential for building foundations, concrete, and roads, making them the second most extracted material globally after water. READ MORE

  7. 15. Mehanics of Rock Fragmentation Static and Dynamic Laboratory Testing Applied to Aggregate Production

    Author : Bahman Bohloli; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropy; aggregates; rock failure; saturation; Brazilian test; dynamic tensile strength; Hopkinson pressure bar; fragmentation; rock fines; crushing;

    Abstract : Knowing the strength properties of rocks is essential for calculating the stability of natural slopes, constructions in and on rock, excavations, blasting geometry, crushing, and drilling. When rock and rock masses are subjected to either dynamic or static loads, the tensile strength is determined by tests appropriate to the load type. READ MORE
