1. Fano Resonances in Time-Dependent Wells
L3-uppsats, Uppsala universitet/MaterialteoriSammanfattning : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. LÄS MER
2. Scalable fabrication of High-Rate On-Paper Microsupercapacitors through full inkjet printing
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : storage devices in micro sizes are receiving more and more attention. One of them, on-paper Microsupercapacitors (MSCs), has become a key energy storage device because of its good mechanical flexibility and high power density. LÄS MER
3. Graphene Quantum Dots as Fluorescent and Passivation Agents for Multimodal Bioimaging
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Zero-dimensional graphene (carbon) quantum dots have been drawing attention in bio-related applications since their discovery, especially for their optical properties, chemical stability, and easily modifiable surface. This thesis focuses on the green synthesis of nitrogen-doped graphene quantum dots (GQDs) for dual-mode bioimaging with X-ray fluorescence (XRF) and optical fluorescence. LÄS MER
4. Detection of Amphetamine with Graphene Quantum Dots
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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
5. The use of graphene quantum dots as detection elements in nanomaterials-based sensors for forensic applications
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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
