  2. 6. Microfluidic Preparation and Transport of Long DNA using Pillar Arrays

    Author : Oskar Ström; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microfluidics; Deterministic Lateral Displacement; DNA Separation; Elastic Turbulence; Micro-pillar arrays; DNA Sample Preparation; Lab-on-a chip; elastic waves; Sample Preparation; DNA Isolation; bumper array; Fysicumarkivet A:2023:Ström;

    Abstract : This thesis presents a set of microfluidic tools and experimental studies for preparing (> 20 kbp) for genetic analysisas well as the transport of high-concentration, long-DNA solutions in pillar arrays.Long-DNA sample preparation with conventional gel-based techniques is slow (tens of hours to days) and laborious.

  4. 7. Influence of microstructure on debonding at the fiber/matrix interface in fiber-reinforced polymers under tensile loading

    Author : Luca Di Stasio; Janis Varna; Zoubir Ayadi; Alberto Barroso; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber matrix interface; Debonding; Polymer-Matrix Composites PMC ; Finite Element Method FEM ; Linear Elastic Fracture Mechanics LEFM ; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : At the end of the second decade of the XXI century, the transportation industry at large faces several challenges that will shape its evolution in the next decade and beyond. The first such challenge is the increasing public awareness and governmental action on climate change, which are increasing the pressure on the industrial sectors responsible for the greatest share of emissions, the transportation industry being one of them, to reduce their environmental footprint.

  5. 8. Strength of Sandwich Panels Loaded in In-plane Compression

    Author : Anders Lindström; Dan Zenkert; Stefan Hallström; Per-Lennart Larsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich; in-plane compression; energy absorption; debond; postbuckling; Engineering mechanics; Teknisk mekanik;

    Abstract : The use of composite materials in vehicle structures could reduce the weight and thereby the fuel consumption of vehicles. As the road safety of the vehicles must be ensured, it is vital that the energy absorbing capability of the composite materials are similar to or better than the commonly used steel structures.

  6. 9. STRUCTURAL RETROFITTING OF CONCRETE BEAMS USING FRP - Debonding Issues

    Author : Yasmeen Obaidat; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : A 3D nonlinear finite element analysis modelling framework was developed for simulating the behaviour of beams retrofitted with fibre reinforced polymer (FRP). The ABAQUS program was used for this purpose. Concrete was modelled using a plastic damage model. READ MORE

  7. 10. Probing nonlinear electrical properties at the nanoscale : Studies in multifrequency AFM

    Author : Riccardo Borgani; David B. Haviland; Peter Grütter; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atomic Force Microscopy; Nonlinear dynamics; Multifrequency; Contact potential difference; Conductance; Fast dynamics; Fysik; Physics;

    Abstract : Nanostructured materials promise great advances in diverse and active research fields such as energy harvesting and storage, corrosion prevention and high-density memories. Electrical characterization at the nanometer scale is key to understanding and optimizing the performance of these materials, and therefore central to the progress of nanotechnology. READ MORE
