  1. 1. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

    University essay from Lunds universitet/Kemiska institutionen

    Author : Simone Facchini; [2022]
    Keywords : organic chemistry; membranes; isatin; polymers; Chemistry;

    Abstract : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. READ MORE

  3. 2. Reactivity and photochemistry of copper halide complexes

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Needa Athitaya Wicksell Chuainukun; [2021]
    Keywords : Photochemistry; Copper iodide complexes; Substituted pyridines; Thin films; Luminescence lifetime;

    Abstract : This paper deals with 3-picoline, 4-picoline, 3,4-lutidine and 3,5-lutidine complexes of copper(I) iodide (CuI(3-pic), CuI(4-pic), CuI(3,4-lut) and (CuI(3,5-lut)). The experimental investigation was divided into several parts. Firstly, the synthesis and characterization of the compounds both as powder and as thin films. READ MORE

  4. 3. Temporal and spatial variations of microplastic concentrations in surface waters in Gothenburg, Sweden.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : David Vigren; [2019]
    Keywords : ;

    Abstract : Temporal and spatial variations of microlitter (ML) concentrations in Gothenburg were measured by sampling surface water. ML was divided into three main categories; microplastics (MP), fibers (F) and other anthropogenic particles (OA). READ MORE

  5. 4. Tribological Performance of Hygrothermally Aged UHMWPE Hybrid Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Luca Palmeira Belotti; [2018]
    Keywords : UHMWPE; aging; polymers; tribology;

    Abstract : Stricter environmental regulations and trend of decreasing cost and increasing operational efficiency are the driving forces for the improvement of the tribological performance in many different industries. For example, in the case of hydropower plants, there has been increasing research carried out to achieve oil-free stations, which would substitute the oil-based lubricants with environmentally accepted lubricants or water.

  6. 5. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

    University essay from Umeå universitet/Institutionen för fysik

    Author : Thomas Moberg; [2018]
    Keywords : Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

    Abstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE
