  1. 1. Evaluation of thermal and mechanical properties of the composite material of LignoBoost- lignin and recycled polyurethan : A preliminary feasibility study for a novel composite material from waste materials

    University essay from Karlstads universitet

    Author : Shaymaa Al-Taee; [2017]
    Keywords : ;

    Abstract : The purpose of this study was to investigate the possibility of producing a composite material of lignoBoost- lignin and recycled polyurethane. Also, the study evaluated the thermal and mechanical properties of the composite materials. READ MORE

  2. 2. Investigation of the native starch-ethyl cellulose film coating for colon targeting

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Mohamed Esmael; Ali Majid; [2016]
    Keywords : starch; colon delivery; pharmaceutical technology; läkemedelsteknologi; Chemistry;

    Abstract : The aim of this study was to optimize a function starch-ethyl cellulose film for targeting the therapeutically active substance to the colon in the disease state for patients suffering from inflammatory bowel diseases. This study includes: • The preparation of the polymeric films and the investigation of the characterization (for example mechanical properties, water uptake, dry mass loss, and microscopy analysis) for these prepared film coatings.

  3. 3. Polymeric single Li+-ion conductors: preparation and characterisation

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hannes Nederstedt; [2016]
    Keywords : single ion conductors; electrolytes; polymers; lithium ion batteries; polymer technology; polymerteknologi; Chemistry; Technology and Engineering;

    Abstract : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated.

  4. 4. Model system study of recycled polyethylene terephtalate and polyprpylene blends

    University essay from Chalmers tekniska högskola/Institutionen för material- och tillverkningsteknik

    Author : Anders Cardfelt; [2015]
    Keywords : recycling; PET; PP; compatibility; chain extesion; maleic anhydride; glycidyl methacrylate; oxazoline;

    Abstract : Recycling of polymers becomes an increasingly important issue because of the environmental impact of petroleum-based polymer production. Legislative motivationalso pushes for polymer recycling with the End-of-Life-Vehicles (ELV) directive dictated by the European Union requiring that a minimum of 85 wt% of vehicles arematerials recycled.

  5. 5. Time-resolved study of charge photo-generation in polymer-based solar cells with low driving force

    University essay from Lunds universitet/Fysiska institutionen

    Author : Paulius Baronas; [2014]
    Keywords : Organic polymer solar cells; BHJ solar cells; Charge photo-generation; Driving force; Time resolved photoluminescence; CT states; Physics and Astronomy;

    Abstract : Organic polymer-based solar cells recently attracted much attention as an efficient and inexpensive light-to-electricity conversion solution. However, the mechanism behind charge generation processes in organic materials is still not fully understood due to complex nature of carbon-based compounds. READ MORE
