  1. 16. Interaction Between Graphene Derivatives and Asphaltenes in Crude Oil and Crude Derivatives

    Författare :Govindan Induchoodan; Chalmers tekniska högskola; []
    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

  3. 17. Mechanical optimization of orthopaedic bone screw constructs

    Författare :Yijun Zhou; Cecilia Persson; Benedikt Helgason; Philip Procter; Richie Gill; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trabecular bone; screw implant; explicit finite element modelling; computed tomography; numerical optimization; neural network; hydrogel; Engineering Science with specialization in Biomedical Engineering; Teknisk fysik med inriktning mot medicinsk teknik;

    Sammanfattning : Orthopaedic screw implants are crucial in surgical procedures for bone structures, with a longstanding issue being screw loosening. Improving screw stability requires an enhanced understanding of the bone-implant interactions and associated failure mechanisms. This knowledge can be used to optimize screw designs. LÄS MER

  4. 18. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport

    Författare :Liming Huang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

    Sammanfattning : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. LÄS MER

  5. 19. Exotic Decays of Vector-Like Quarks and Development of a Test Procedure for the ITk Strip Module at the ATLAS Detector for the HL-LHC

    Författare :Thomas Mathisen; Elin Bergeås Kuutmann; Venugopal Ellajosyula; Richard Brenner; Freya Blekman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Standard Model; BSM; Composite Higgs; Fine-tuning; Naturalness; Vector-Like Quarks; HL-LHC; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Sammanfattning : The naturalness problem of the Standard Model (SM) challenges our understanding of the origin of mass. Several theories have been proposed to tackle the problem, one of them is the Composite Higgs Model (CHM) where the Higgs boson of the SM is not an elementary scalar but instead a composite object bound at a confinement scale of a TeV.

  7. 20. Study of particle-current-electrocrystallization interactions in electroplating of Ni/SiC coatings

    Författare :Santiago Pinate; Caterina Zanella; Peter Leisner; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite coatings; Nanoparticles; Electrocrystallisation; Microstructure; Surface treatment; Pulse plating; Ultrasound agitation; Kompositbeläggningar; Nanopartiklar; Elektrokristallisering; Mikrostruktur; Ytbehandling; Pulsplätering; Ultraljudsomrörning;

    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
