    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials chemistry; Material and Nano Physics; Material- och nanofysik; Fysik; Physics;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. 3D printing of Green Water Purification Filters : Design towards Sustainable and Scalable Biocomposite Materials

    Author : Natalia Fijoł; Aji P. Mathew; Lennart Bergström; Alexander Bismarck; Stockholms universitet; []

    Abstract : This thesis starts with the premise that to address ecological and climate crises, we need to understand their psychological and cultural roots found in the separation of modern societies from the natural world. This separation permeates mainstream approaches to sustainability that either sustain business-as-usual of the unbridled economic growth, or reform it with greener markets and technologies. READ MORE
