  1. 16. Detection of Amphetamine with Graphene Quantum Dots

    Master-uppsats, KTH/Tillämpad fysik

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

    Sammanfattning : 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. LÄS MER

  3. 17. A comparison between LiF, Al2O3 and NaCl pellets for luminescence dosimetry based on clinical and laboratory measurements

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Edita Solak; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Radiation protection is of importance for the general public, patients and personnel in many different situations: rare accidents involving ionizing radiation, medical examinations or work tasks in the medical clinic or nuclear industry to name a few. Optimization in radiation protection and limitation of radiation doses are essential to prevent overexposure and for reducing negative health consequences. LÄS MER

  4. 18. Optical Study of Micro-Resonators with G-centers as an Active Medium

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Baptiste Lefaucher; [2021]
    Nyckelord :G-center; Silicon Photonics; Micro-Resonators Optics; Laser; Photo-Luminescence Spectroscopy; G-center; Kiselfotonik; Mikroresonatoroptik; Laser; Fotoluminescensspektroskopi;

    Sammanfattning : The G-center has recently been identified as the first deterministic single-photon punctual emitter isolated in silicon. This discovery is of great interest for largescale quantum technologies, due to the abilities of silicon in terms of integration and scalability. LÄS MER

  5. 19. High Sampling Resolution Luminescence Dating of Loess in Brittany, France

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Vanda Jakabová; [2021]
    Nyckelord :aeolian dust; loess; luminescence; dMAR; Brittany; LGM; palaeoenvironment; eoliskt damm; loess flygmo ; luminescens; dMAR; Bretagne; LGM; paleomiljö;

    Sammanfattning : Aeolian dust is an important but poorly understood component of the climate system, which both responds to and drives global climate. Recently, dust produced at the high latitudes is also gaining attention as a possible contributor to the atmospheric dust load. LÄS MER

  7. 20. Photochemistry of Copper Coordination Complexes

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Amanda Blad; Helena Glisén; Filippa Ludvig; [2021]
    Nyckelord :Copper Halide Organic Complex; Time-Resolved Photoluminescence; Metal-organic Framework; Coordination Polymer; Thin Film Solar Cell; Koppar halid organiska komplex; tidsberoende fotoluminesens; metallorganiska ramverk; koordinationspolymer; tunnfilmssolcell.;

    Sammanfattning : The United Nations have set a number of sustainability goals, Agenda 2030, in order to combat the worlds largest challenges and injustices. The energy market is one of these urgent issues which must be solved. Solar energy is expected to be the fastest growing energy source in the future energy mix. LÄS MER
