  1. 6. Size effect in wood : Characterization of mechanical properties using digital image correlation method

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Amir Saeidi; Olafur Johannsson; [2023]
    Keywords : compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

    Abstract : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. READ MORE

  3. 7. Protein-based hydrogel electrolytes for stretchable Zn-ion batteries

    University essay from Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Author : Lovisa Byström; [2023]
    Keywords : Hydrogel; gelatin; kappa-carrangeenan; Zn-ion battery; Kemisk biologi; Kemisk biologi;

    Abstract : Stretchable aqueous-based Zn-ion batteries have shown promise as a sustainable and safe energy storage system for wearable electronics used in healthcare, sports, soft robotics, and prosthetics. A battery consists of the active electrode, electrolyte, current collector, and encapsulation. READ MORE

  4. 8. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Sundmark; [2023]
    Keywords : Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

    Abstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

  5. 9. Anisotropic Muscle Phantoms for Shear Wave Elastography Assessment of the Levator Ani Muscle Properties

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Bleona Koxha; Melissa Jova Martinez; [2023]
    Keywords : pelvic floor disorder; levator ani muscle; shear wave elastography; phantom; anisotropy; polyvinyl alcohol; bäckenbottenbesvär; levator ani muskel; shear wave elastografi; fantom; anisotropi; polyvinylalkohol;

    Abstract : Pelvic floor disorder is an emerging research area and is highlighted in many pelvic floor studies. Assessment methods for this type of injury are lacking and new methods for prevention and diagnosis are needed. Pelvic floor disorders are common among women and can lead to suffering for the patient. READ MORE

  6. 10. Decellularized ECM derived collagen bioinks

    University essay from Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Author : Matilda Carlson; [2023]
    Keywords : ;

    Abstract : 3D bioprinting allows for the manufacturing of tissue-like structures that could be used for culturing and studying cells in a microenvironment representative of the cell’s natural environment. In recent years, hydrogel bioinks from different biomaterials have been in development and utilized in tissue engineering applications. READ MORE
