  1. 1. Detection of Amphetamine with Graphene Quantum Dots

    University essay from KTH/Tillämpad fysik

    Author : Carl Fredrik Åslund; [2021]
    Keywords : Graphene quantum Dots; Amphetamine; Sensor; GQD; Grafen kvantprickar; Amfetamin; Sensor; GQD;

    Abstract : Amphetamine abuse is an enduring problem in many developed nations, including Sweden. It causes lasting damage both to its users and in the form of increased strain on healthcare services. It is therefore critical that police be equipped with the tools necessary to rapidly and accurately identify any samples in order to combat this scourge. READ MORE

    Abstract : Thin film coatings of ZnO, TiO2, CeOX and BiOX have been deposited on soda lime silica glass through spray pyrolysis. The effects on the optical properties of the coated glass, as well as the possible impacts on the life expectancy and energy efficiency of PV-modules have been studied. READ MORE

  5. 4. Role of annealing and photostability of organo-metal-halide semiconductors for solar cell applications

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : David Sörell Jonsson; [2016]
    Keywords : materials chemistry; materialkemi; Chemistry;

    Abstract : Methyl ammonium lead halides (MAPbX3 , X=Cl-, Br-,I-), crystallizing in a perovskite structure, have in recent years been shown to be a promising material as a light harvesting material in solar cells. It has many interesting properties which makes it suitable for solar cell applications, such as near-optimal band gap and long electron-hole diffusion lengths, as well as the possibility of synthesizing the films from solution based methods.
