  1. 21. The use of graphene quantum dots as detection elements in nanomaterials-based sensors for forensic applications

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Xiaofan Ma; [2021]
    Nyckelord :Graphene Quantum Dots; Amphetamine; Cocaine; Chemical Sensor; Forensic Drugs; Grafenkvantprickar; amfetamin; kokain; kemisk sensor; rättsmedicinska läkemedel;

    Sammanfattning : The large-scale abuse and addiction of narcotics such as amphetamine and cocaine have become a global problem. In this project, we innovatively use graphene quantum dots (GQDs) as a fluorescent sensor to detect and quantify amphetamine and cocaine. This technology will have broad forensic application prospects. LÄS MER

  3. 22. Determination of depositional environment and luminescence dating of Pleistocene deposits in the Biely Váh valley, southern foothills of the Tatra Mountains, Slovakia

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Ingrid Bejarano Arias; [2020]
    Nyckelord :Luminescence dating; glacifluvial deposits; sedimentological analysis; High Tatra Mountains; IRSL dating.; Earth and Environmental Sciences;

    Sammanfattning : The Tatra Mountains have had several glaciations during the Quaternary. The deposits located in the southern foothills were classified as glacifluvial, based on geomorphology, but its sediments have not been studied in detail. LÄS MER

  4. 23. Combining luminescence dating and sedimentary analysis to derive the landscape dynamics of the Velická Valley in the High Tatra Mountains, Slovakia

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Roos van Wees; [2020]
    Nyckelord :IRSL; Chronology; Sedimentology; Landscape development; Middle Pleistocene; Modern Analogues; Clast shape analysis; Maximum particle size; High Tatras; Slovakia; Earth and Environmental Sciences;

    Sammanfattning : Luminescence dating is widely used in combination with sedimentological analysis to reconstruct the landscape development of the Quaternary period. Here, quartz and K-feldspar measurements are used to date and evaluate the luminescence characteristics of sediments from seven sites of the lower part of the Velická valley (995-1250 m a.s.l.

  5. 24. The Roles of Light: Artificial Light as a Resource in Public Art

    Magister-uppsats, KTH/Ljusdesign

    Författare :Mateus Manninen; [2020]
    Nyckelord :Public art; light art; public space; case study; nordic; daylight conditions;

    Sammanfattning : In this paper, I will explore the role of artificial light in public art through a case study project. With the word role, I mean the visual and conceptual hierarchy of materials and resources in artwork. Light is a significant resource in public art. LÄS MER

  7. 25. Eoliska avlagringar och vindriktningar under holocen i och kring Store Mosse, södra Sverige

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Tim Bjermo; [2019]
    Nyckelord :Store Mosse; optiskt stimulerad luminiscens OSL ; kvartsdatering; flygsand; eoliska dyner; holocen; fjärranalys; LiDAR; optically stimualted luminiscence OSL ; quartz dating; aeolian sand; aeolian dunes; Holocene; remote sensing.; Earth and Environmental Sciences;

    Sammanfattning : Eoliska sanddyner är en sällan undersökt resurs ur ett paleoklimatperspektiv. Genom att undersöka dynernas geomorfologi och strukturer kan de klassificeras som olika dyntyper. Eoliska sanddyner kräver speciella omständigheter och förutsättningar för att bildas och agerar värdefulla klimatarkiv för de tidperioder då de avsatts. LÄS MER
