  1. 1. A photodegradation study of conjugated polymers for organic solar cells by absorption spectroscopy and atomic force microscopy

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Johansson André; [2021]
    Keywords : OSC; solar cells; active layer; polymer; degradation;

    Abstract : The effect of light exposure in ambient air on thin films made from an electron acceptor polymer poly{[N,N'-bis(2-octyldodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (N2200), an electron donor polymer Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] (TQ1) and their blends, has been studied using UV-vis spectroscopy and Atomic Force Microscopy (AFM). For solutions of TQ1, N2200 and blends, the linearity of the Beer-Lambert law for absorption spectroscopy has been verified. READ MORE

  2. 2. Synthesis and Characterization of Copper Halide Complex Materials

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Hiroki Tomita; [2021]
    Keywords : Copper halide complexes; Coordination polymers; Photoluminescence; Bidentate ligands; Applications of thin films; Kopparhalogenidkomplex; koordinationspolymerer; fotoluminiscens; bidentata ligander; tillämpningar av tunna skikt;

    Abstract : Energiförbrukning är ett hett ämne i världen idag, eftersom världens befolkning fortsätter att växa. Som ett resultat ökar också den globala energiförbrukningen snabbt och utsläppen av koldioxid därmed, vilket påverkar global uppvärmning och klimatförändringar. READ MORE

  3. 3. The Home Office, A New Perspective on Workstation Design

    University essay from Lunds universitet/Produktutveckling

    Author : Johan Rogberg; [2021]
    Keywords : Workstation; Home office; Office furniture design; Covid-19; Technology and Engineering;

    Abstract : The development of office furniture design has been stagnant while digital technology has changed drastically over the last decades. There is a need for a new approach in order to bring the design of the office workstation into the future, which this thesis sets out to contribute to. READ MORE

  4. 4. Detection of nitrous oxide through IR-DFWM in gas flows with future application in ammonia flames

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Martin Passad; [2021]
    Keywords : Physics; Optics; Lasers; Environment; Hydrogen; Hydrogen Energy; Ammonia Energy; DFWM; Ammonia; Nitrous Oxide; Ammonia Flame; Ammonia Combustion; Physics and Astronomy;

    Abstract : This thesis report on an investigation into the applicability of mid-infrared degenerate four-wave mixing (IR-DWFM) as a method to detect N\(_2\)O in ammonia flames. DFWM has previously been used for concentration measurements on other molecules, but has never, to the author's knowledge, been applied to measure N\(_2\)O in ammonia flames before. READ MORE

  5. 5. Using embedded systems to optimize the care of indoor plants

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS); KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anton Åbonde; Simon Salas Amnér; [2020]
    Keywords : Internet of Things; Embedded Systems; Sensors; Indoor Environment; Sakernas internet; Inbyggda system; Sensorer; Inomhusmiljö;

    Abstract : Over the last few years the interest in indoor plants has increased. Whether they are used for decorating, as mood boosters or sometimes as food in cooking, people want to come closer to nature by bringing it into their homes. However removing plants from their natural habitat could have negative implications on their well-being. READ MORE
