  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

  3. 2. Photophysics of blood on a crime scene

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Patric Elf; [2018]
    Keywords : ;

    Abstract : The purpose of this study is to analyze the possibility to age-determine blood spots with the help of enzymes which blood contains, in order to see if with these results it's possible to give an estimate of how long it has been since blood left the body. The main domain of this would be that of a crime-scene in order to give a time-frame of when a crime has been commited. READ MORE

  4. 3. Svartpricksjukans betydelse för skalkvalitet i matpotatis

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Philip Zandelin; [2018]
    Keywords : svartpricksjuka; black dot; Colletotrichum coccodes; skalsjukdomar; potatis; Solanum tuberosum;

    Abstract : I Sveriges odlas mer än en halv miljon ton matpotatis (Solanum tuberosum) årligen. I takt med att potatisen tvättas och paketeras i allt större utsträckning har kraven på utseende och storlek fått en ökad betydelse. Det har inneburit att skalmissfärgningar fått en ökad betydelse.

  5. 4. Growth and characterization of Ge quantum dots on SiGe-based multilayer structures

    University essay from Institutionen för fysik, kemi och biologi

    Author : Andreas Frisk; [2009]
    Keywords : Ge dots; SiGe; Thermistor; IR-detector; Bolometer; intermixing; strain;

    Abstract : Thermistor material can be used to fabricate un-cooled IR detectors their figure of merit is the Temperature Coefficient of Resistance (TCR). Ge dots in Si can act as a thermistor material and they have a theoretical TCR higher than for SiGe layers but they suffer from intermixing of Si into the Ge dots. READ MORE

  6. 5. Structural and optical characterization of Si/Ge quantum dots

    University essay from Institutionen för fysik, kemi och biologi

    Author : Dan Wigblad; [2008]
    Keywords : quantum dot; IR detector; bolometer; semiconductor; germanium; silicon;

    Abstract : In this study silicon-germanium quantum dots grown on silicon have been investigated. The aim of the work was to find quantum dots suitable for use as a thermistor material. The quantum dots were produced at KTH, Stockholm, using a RPCVD reactor that is designed for industrial production. READ MORE
