3. 17. Solution Chemistry and Morphological Properties for Organic Solar Cells : Exploring Alternative Solvents Using Microgravity and Modelling as Tools

   Författare :Ishita Jalan; Jan van Stam; Patricia Saenz Mendez; Stela Andrea Muntean; Mariano Campoy-Quiles; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solution chemistry; green solvents; microgravity; OPV; HSP; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

   Sammanfattning : Organic photovoltaics (OPVs) have the advantage of the accessibility of energy for all, due to facile and low-cost processing, with its low energy payback time compared to other technologies, therefore promising applications. Research and development have led to power conversion efficiencies of nearly 20% and now catching up to their inorganic counterparts. LÄS MER

   Författare :Magnus Stödeman; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Aqueous Solution; Calixarene; Cyclodextrin; Vaporization; Macrocyclic compounds; Microcalorimetry; Kemi;

   Sammanfattning : The present work involves a microcalorimetric characterization of the interactions among macrocyclic compounds and aliphatic molecules in aqueous solution. The macrocyclic compounds used in the study are a-,b- and g-cyclodextrin and 25,26,27,28-tetrahydroxycalix[4]arene-5,11,17,23- tetrasulphonate. LÄS MER

5. 19. Integrating Digital Transformation and Sustainability in Manufacturing : The Role of Small Technology Solution Providers

   Författare :Hossein Rahnama; Anna Rönnbäck Öhrwall; Seyoum Eshetu Birkie; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Collaboration; digital transformation; sustainability; technology solution providers; SME; Produktinnovation; Product Innovation;

   Sammanfattning : This study focuses on the role of small technology solution providers (TSPs) in supporting digital transformation and sustainability in the manufacturing sector. It explores the challenges and opportunities of developing and adopting tailor-made technology solutions for sustainable production and the role of TSPs in the design, development, and implementation of such solutions in value constellations.

7. 20. Protein-Surfactant Interactions Phase Behaviour and Phase Structure

   Författare :Anna Karin Morén; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phase equilibria; Protein-surfactant interactions; Gel; Precipitate; Solution; Lysozyme; b-lactoglobulin; Ovalbumin; Bovine serum albumin; Dodecyltrimethylammonium chloride; Sodium alkylsulphates; NMR; Cryo-TEM; Physical chemistry; Fysikalisk kemi;

   Sammanfattning : Protein-surfactant interactions in water are investigated by following the phase equilibria for protein-surfactant pairs whose constituents carry both opposite and the same sign of charge. The concentration ranges studied are: 0-20 wt% protein, 0-20 wt% surfactant, and 80-100 wt% water. LÄS MER
