  2. 6. Light propagation and photonic functionalization of semi-ordered material (transparent wood)

    Author : Adil Baitenov; Sergei Popov; Sergey Ponomarenko; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; light scattering; scattering material; hierarchical structure; FEM model; wood modification; random lasers; dye lasers; transparent wood; adsorption; diffusive media; Optics and Photonics; Optik och fotonik;

    Abstract : Investigating novel materials requires understanding their chemical and optical properties, which allows for finding their uses through functionalization by chemical modification. In this thesis, we are focusing on a material with high anisotropic scattering - transparent wood. READ MORE

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transparent wood; cellulose; biocomposite; light transmission; anisotropic scattering; Rayleigh scattering; photon budget; photon diffusion theory; light-transparent wood interaction; Transparent trä; cellulosa; biokomposit; ljustransmission; anisotropisk spridning; Rayleigh-spridning; fotonbudget; fotondiffusionsteori; ljus-transparent trä interaktion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Transparent wood (TW) shows interesting optical properties and offers a sustainable alternative to petroleum-based polymer glasses. The influence of the TW internal structure (e.g. READ MORE

  5. 8. Light propagation in an anisotropically scattering medium

    Author : Elena Vasileva; Sergei Popov; Miguel A. Alonso; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropic light scattering; scattering material characterization; polarization dependent scattering; diffusive media; hierarchical structure; biocomposites; wood modification; transparent wood; microfibrils angle; organic materials; polymer active devices; dye lasers; coherence; polarization; degree of polarization.; Fysik; Physics;

    Abstract : Scattering is the main phenomenon of light-matter interaction. In this thesis, we consider one specific case of light propagation in a material whose structure causes anisotropic optical scattering - transparent wood. READ MORE

  6. 9. Advanced surgeries, medicines and materials for corneal regeneration

    Author : Maria Xeroudaki; Neil Lagali; Beatrice Bourghardt Peebo; Per Fagerholm; Stefan Schrader; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Corneal transplantation is often the only treatment option in cases of corneal blindness, with the main challenges being the scarcity of human donors, risk for graft failure and suboptimal visual outcome due to suture-related issues. Alternative therapies are sought that either address the above transplantation issues directly or stimulate the cornea’s repair mechanism and regenerative properties to restore transparency without the need for transplantation.

  7. 10. Eco-friendly Holocellulose Materials for Mechanical Performance and Optical Transmittance

    Author : Xuan Yang; Lars Berglund; Eero Kontturi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulosic materials can be sustainable replacements for fossil-based plastics; yet for some applications improvements are needed for mechanical properties, optical transmittance and eco-friendly characteristics. In this thesis, holocellulose materials are investigated for this purpose, and processing-structure-property relationships are discussed. READ MORE
