  2. 1. Electrolyte-Based Dynamics: Fundamental Studies for Stable Liquid Dye-Sensitized Solar Cells

    Author : Jiajia Gao; Lars Kloo; Elizabeth Gibson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; Stability; Electrolyte; Cobalt redox couples; Additives; Kemi; Chemistry;

    Abstract : The long-term outdoor durability of dye-sensitized solar cells (DSSCs) is still a challenging issue for the large-scale commercial application of this promising photovoltaic technique. In order to study the degradation mechanism of DSSCs, ageing tests under selected accelerating conditions were carried out. READ MORE

  4. 2. Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation

    Author : Marisa Punzi; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Azo dye; textile wastewater; biological treatment; biofilm; microbial community; DGGE; green algae; photo-Fenton; ozone; toxicity; mutagenicity; LCA; cost analysis;

    Abstract : Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. READ MORE

  5. 3. Synthesis and Robotized Screening of Novel Perovskite Materials for Solar Cell Application

    Author : Allan Starkholm; Lars Kloo; Per H. Svensson; Kasper Moth-Poulsen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perovskite solar cell; Photovoltaic device; Lead-free light absorbers; Polyiodide; Dye-sensitization; Robotized Screening; Screening; Kemi; Chemistry;

    Abstract : As of today, the energy consumption in the world is high and is essential in the development and growth of the modern-day society. The world energy consumption is projected to increase significantly over the next decades. READ MORE

  6. 4. Laccases from New Fungal Sources and Some Promising Applications

    Author : Laura Mendoza; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fungi; ligninases; modification of primary alcohols; modification of lignin; laccase applications; dye decolorization;

    Abstract : Fungi are a group of organisms with the ability to produce different types of enzymes in order to get access to nutrients. Among the enzymes, oxidoreductases have the ability to degrade lignocellulosic material via an oxidative mechanism, facilitating the uptake of cellulosic material, which will be metabolized using other enzymes to provide the required nutrients to the fungi.

  7. 5. Biomass-derived nanoscopic catalysts for water treatment : Structure-property relationship investigation

    Author : Jianhong Chen; Adam Slabon; Germán Salazar Alvarez; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; green chemistry; water purification; electrochemistry; photochemistry; biomass material; structure-property relationship; oorganisk kemi; Inorganic Chemistry;

    Abstract : Green Chemistry has received widespread interest due to its capacity to meet environmental and economic objectives. The Twelve Principles were proposed to better perform Green Chemistry and have become the guideline for solving many environmental issues. Water contamination has become a major global challenge in the 21st century. READ MORE
