  1. 6. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Bilel Meskini; [2023]
    Keywords : E-textile; viscose; polyester; graphene; graphene oxide GO; reduced graphene oxide rGO; tannic acid; plasma treatment; electrochemical deposition; doping; semiconductor;

    Abstract : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. READ MORE

  3. 7. Data Assimilation for Systems with Multiple Timescales

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Dan Vicente Ihanus; [2023]
    Keywords : Mathematics; Partial Differential Equations; Numerical analysis; Data assimilation; Numerical weather prediction; Ensemble Kalman Filter;

    Abstract : This text provides an overview of problems in the field of data assimilation. We explore the possibility of recreating unknown data by continuously inserting known data into certain dynamical systems, under certain regularity assumptions. READ MORE

  4. 8. SFEER Hydrogen Permeation : Finding a suitable coating for the PA6 liner

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Elsa Friis; Klara Karlsson; Rebecka Damgren; Emma Åkesson; Malin Johansson; [2023]
    Keywords : Hydrogen permeation; PA6; coating; hydrogen permeation barrier; polymer hydrogen permeation; permeation; protective coating; hydrogen embrittlement;

    Abstract : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6.

  5. 9. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Francisco Gonçalves Jorge Dias de Carvalho; [2023]
    Keywords : Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

    Abstract : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. READ MORE

  6. 10. Buffer modification: A case study with polystyrene beads, DU145-, and MCF7 cell lines

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Olivia Hansson Rengbrandt; [2023]
    Keywords : Technology and Engineering;

    Abstract : Separation of cancer cells gives advantages in understanding the disease, guiding treatment decisions, and facilitating drug development. Overall, separation plays an important role in biological research. Acoustophoresis is a technique that utilizes acoustic waves to separate particles and cells suspended in a buffer medium. READ MORE
