1. 1. Water-based Synthesis of Superparamagnetic X-ray Fluorescent Contrast Agents

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Daniel Cortés García; [2022]
   Nyckelord :Nanoparticles; SPIONs; XFCT; co-precipitation.; Nanopartiklar; SPIONs; XFCT; samfällning;

   Sammanfattning : Nowadays, nanomedicine is one of the most important application areas fornanoparticles (NPs), where the design and synthesis of new hybrid nanostructures have attracted much interest, when combining properties and functionalities from different constituents. For example, they have been extensivelyused for dual-mode imaging. LÄS MER

3. 2. Elastic hyperspectral lidar for detecting coherent backscatter from insects

   Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Författare :Lauro Müller; [2022]
   Nyckelord :Nanosopy; Thin film physics; Hyperspectral; Lidar; Super continuum; Insects; Coherent scattering; Infrared Spectroscopy; Hyperspectral Imaging; Biophotonics; Technology and Engineering;

   Sammanfattning : Insects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis.

4. 3. Fabrication and Evaluation of Sb2Te3/PVDF Hybrid Thermoelectric Films

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Bo Yu; [2020]
   Nyckelord :;

   Sammanfattning : Thermoelectric (TE) materials and devices have been extensively studied for harvesting waste heat energy. There is more interest to fabricate TE materials and devices at low cost and highly-efficient ways. LÄS MER

5. 4. Artificial photosynthesis - 4-Aminobenzoic acids effect on charge transfer in a photo catalytic system

   Kandidat-uppsats, Uppsala universitet/Materialteori

   Författare :Simon Moberg; [2019]
   Nyckelord :artificial photosynthesis; aminobenzoic acid; charge transfer; plasmon; induced; plasmon induced; nanostructure; nanostructures; solar energy; nano particles; nano particle; artificiell fotosyntes; aminobensoesyra; laddningsöverföring; plasmon; inducerad; plasmoninducerad; nanostruktur; nanostrukturer; solenergi; nanopartiklar; nanopartikel;

   Sammanfattning : Artificial photosynthesis is used to harvest solar energy and store it in the form of chemical bonds. The system of interest in this study does this by splitting water into hydrogen and oxygen gas through a plasmon assisted process, collective oscillations from free electron gas. LÄS MER

7. 5. Fabrication and Characterization of Nano-Confined Pd Catalysts for CO Oxidation

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Alfred Larsson; [2019]
   Nyckelord :Catalysis Palladium Nano Nanopore CO oxidation; Physics and Astronomy;

   Sammanfattning : During this thesis nanoporous alumina has been used as a template for the synthesis of nano-confined palladium structures. The nanoporous templates have been synthesized by anodization of aluminum and characterized using atomic force microscopy (AFM), scanning electron microscopy (SEM) and small angle X-ray scattering (SAXS), resulting in good statistics of the pore diameter and interpore distance of these nanoporous structures.
