    Sammanfattning : The demand for energy is rapidly increasing, triggering more carbon emission and global warming. Alternative green energy sources are essential to secure the future generation from the effect of pollution and global warming. LÄS MER

  5. 4. Dynamics in Blue Emitting Metal Halide Perovskites for Light Emitting Diodes

    Författare :Max Karlsson; Feng Gao; Tze Chien Sum; Barry P. Rand; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perovskites; Light-emitting diodes; Stability; Efficiency;

    Sammanfattning : Lighting comprises a large part of the global electricity consumption as of today, and the use of lighting in illumination and displays is only projected to grow. It is therefore imperative to meet this energy demand, not only by means of greener energy production, but also with materials that are both more efficient to fabricate as well as to use. LÄS MER

  7. 5. 3D printing of Green Water Purification Filters : Design towards Sustainable and Scalable Biocomposite Materials

    Författare :Natalia Fijoł; Aji P. Mathew; Lennart Bergström; Alexander Bismarck; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D printing; water treatment; polylactic acid; nanocellulose; nanochitin; hydroxyapatite; green metal-organic frameworks; materialkemi; Materials Chemistry;

    Sammanfattning : The globally escalating water pollution and water scarcity necessitates the development of efficient and sustainable water treatment technologies. This thesis investigates the feasibility of utilizing renewable and waste materials in the form of green composites for the fabrication of water purification filters via Fused Deposition Modelling (FDM).
