    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amphiphilic; diffusion; oil; mixture analysis; CORE; stability; NMR; pulsed gradient spin echo; light scattering; XPS; asphaltene; chemical interactions;

    Sammanfattning : Asphaltenes are high-molecular weight, highly aromatic molecules that have a strong tendency to aggregate. Asphaltenes are found in oil and may, if they form particles, cause problems during oil production and handling. LÄS MER

  4. 3. Interaction Between Graphene Derivatives and Asphaltenes in Crude Oil and Crude Derivatives

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micelle Structures; Material enhancement; Enhanced Roads; Graphene; Asphaltene deposition; Structure-Function;

    Sammanfattning : The chemistry of crude oil (SARA) and crude derivatives, and the percentage of asphaltene can vary significantly depending on external and internal factors such as the source and method of SARA extraction. If graphitic materials are introduced into a system such as SARA, it becomes an additional variable to a complex multi-phase colloid. LÄS MER
