  1. 1. Implementation of Level of Development for BIM Collaboration in Timber Building Subsystems Design: A Case Study of I-Joist Construction Elements

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Isabell Gustafsson; [2024]
    Keywords : BIM; I-Joist; LOD; Level of Development; Timber Building Subsystems;

    Abstract : Due to time, cost, and environmental challenges, wood has become a more common building material even for more complex buildings. Implementing the concept of Level of Development (LOD) on timber structures could provide a tool for BIM collaboration that may save cost and time, and in the early stages mediate wood as an available building material.

  3. 2. Surface Functionalization of Nanowires Using Silane-PEG Compounds

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hedvig Ekfors Elvin; [2022]
    Keywords : Functionalization; Nanowires; Silanization; Surface Chemistry; Materials Chemistry; Chemistry;

    Abstract : Introduction: GaP nanowires were functionalized using silane-PEG-NH2 and compared with cellulose acetate, PAcrAm™-g-(PMOXA, amine, silane) and a non-functionalized reference sample. Functionalization would allow strong, covalent anchoring of antibodies instead of adsorption. READ MORE

  4. 3. On the Identification of Nonlinear Optima in Spatially Developing Boundary Layer Flow

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Emanuel Taschner; [2021]
    Keywords : transition to turbulence; nonlinear stability analysis; boundary layer flow; övergång till turbulens; icke-linjär stabilitetsanalys; gränsskiktsflöden;

    Abstract : The present thesis studies transition to turbulence in a spatially developing bound-ary layer for subcritical Reynolds numbers. A fully nonlinear iterative direct-adjoint optimisation technique is employed to identify finite amplitude perturbations triggering transition in an energy efficient way. READ MORE

  5. 4. CCS via Electrochemical CO2 Reduction to Ethylene-based Polymeric Construction Materials

    University essay from KTH/Kemiteknik

    Author : Christian Taylor; [2021]
    Keywords : CCS; Electrochemical CO2 Reduction; CO2 to Ethylene; Power-to-X; Polymeric Construction Materials; Circular Carbon Economy; Electrolysis; CO2 electroreduction; CCS; Elektrokemisk CO2-reduktion; Koldioxid till Eten; Power-to-X; Polymera konstruktionsmaterial; Cirkulär kolekonomi; elektrolys; CO2-elektroreduktion;

    Abstract : IPCC SR15 rapporterade att alla framtida scenarier för att begränsa klimatförändringen till 1,5°C är starkt beroende av negativa utsläppstekniker, såsom geografisk CO2-lagring som används av Stockholm Exergi’s Värtaverket. Men kan man uppnå starkare klimatvinster genom en cirkulär koldioxidekonomi? Bildandet av en cirkulär koldioxidekonomi är absolut nödvändigt för att uppnå global koldioxidneutralitet, men hur kommer vi dit? Elektrolys av CO2 erbjuder en ekonomiskt och miljömässigt attraktiv väg för att uppgradera CO2-utsläpp till värdefulla bränslen och råvaror, vilket minskar användningen av fossila resurser och CO2-utsläpp till atmosfären.

  6. 5. Selective recovery of lithium from thermally pretreated Li-ion batteries by the leaching process

    University essay from KTH/Kemiteknik

    Author : Srija Balachandran; [2020]
    Keywords : Electric vehicles; Li-ion batteries; a combined method of recycling; pyrolysis; incineration; water leaching; Elektriska fordon; Li-ion-batterier; en kombinerad metod för återvinning; pyrolys; förbränning; vattenlakning;

    Abstract : LIBs have become an ideal choice in the EVs batteries and stationary storage applications due to their invaluable advantages. The demand for LIBs is projected to increase due to the growth in the sale of EVs. READ MORE
