  1. 11. A high-order artificial viscosity finite element method for the Vlasov-Poisson system

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Junjie Wen; [2023]
    Keywords : ;

    Abstract : We introduce a finite element method with high-order accuracy for approximating the Vlasov-Poisson system. This method uses continuous Lagrange polynomials as basis functions and employs explicit Runge-Kutta schemes for time discretization. A residual-based artificial viscosity technique is applied for stabilization. READ MORE

  3. 12. 3D Printing Hydrogel Artificial Muscles and Microrobotics

    University essay from KTH/Kemiteknik

    Author : Malin Alterby; Emily Johnson; Anton Jonason; Denize Svensson; [2023]
    Keywords : 3D printing; MXene; CNT; CNF; hydrogel; actuator;

    Abstract : The purpose of this lab was to investigate the printability of cellulose nanofiber/carbon nanotubes, their functions as actuators, and to compare these properties with MXene/nano cellulose gels. Data on MXene/nano cellulose gel was obtained from previous research made by Hamedi labs. READ MORE

  4. 13. Investigation of new hot melt adhesives with plasticisers based on renewable resources : Investigating the use of sustainable plasticisers in hot melt adhesives

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Shadi Feyzabi; [2023]
    Keywords : Hot melt adhesives; renewable; mineral oil; vegetable oil; rheology; viscosity; loop tack; adhesive strength; Smältlim; förnybar; mineralolja; vegetabilisk olja; reologi; viskositet; loop tack; vidhäftningsstyrka;

    Abstract : Hot melt adhesives (HMA) are a class of adhesives that, unlike solvent-or waterborne counterparts, do not contain organic solvents or other carriers, and are produced and subsequently applied in a molten state. The main components of HMA are polymers, tackifying resins, and a plasticiser. READ MORE

  5. 14. Modeling for characterization of continuous casting simulator using CFD

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Filip Reineholm-Hult; [2023]
    Keywords : Continuous casting; CFD; computational fluid dynamics;

    Abstract : In order to improve the continuous casting process of steel, it’s important to have an understanding of the fuid mechanics of the casting process. As experiments on a real caster are usually impractical, both physical and numerical modeling are important for creating this understanding. READ MORE

  6. 15. Fabrication of battery separator by coating with sulfonated cellulose nanofibrils on kraft paper and inkjet paper substrates : Tillverkning av batteriseparator genom bestrykning med sulfonerad cellulosananofibriller på kraft papper och bläckstråle papper substrat

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Forat Alshogran; [2023]
    Keywords : modified nanocellulose; coating; battery separator; contact angle; mechanical strength; permeance; ionic conductivity;

    Abstract : Modified nanocellulose have distinctive qualities and have drawn a lot of interest from a variety of fields. It is a natural, sustainable product that is manufactured from plant-based materials like wood and other renewable resources. It is also biodegradable. READ MORE
