1. 1. Nanoparticle synthesis analysis : Program for data visualization and cluster analysis of nanoparticle synthesis protocols

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Emil Juviken Hultman; Jacob Signeul; Lucas Lindborg; Eskil Silfur; [2023]
   Keywords : Dataanalysverktyg;

   Abstract : As energy demands rise across the globe, new clean energy solutions must be developed. Peafowl Plasmonics is developing a direct solar harvesting device using plasmonic technology. To expand their business and increase manufacturing scalability, nanoparticle synthesis protocols must be made. READ MORE

3. 2. Fabry Pérot Nanocavity Produced via Solution Methods

   University essay from Uppsala universitet/Materialfysik; Uppsala universitet/Fysikalisk kemi

   Author : Stylianos Kioumourtzoglou; [2023]
   Keywords : Plasmonics; Photocatalyis; Fabry Pérot nanocavity;

   Abstract : Plasmonics have attracted significant attention from the scientific community for photoelectrode technologies since they offer tunability, large light absorption cross-sections, transparency and potential scalability. On the downside, plasmonics exhibit large absorption cross sections in a narrow window compared to the total electromagnetic spectrum, leading to relatively small efficiencies. READ MORE

4. 3. Detection of Contaminants in Water Using Surface Enhanced Raman Spectroscopy

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Freja Hansson; [2021]
   Keywords : Raman; Surface-enhanced Raman Spectroscopy; nanoparticles; contaminants; plasmonics;

   Abstract : Due to deteriorating water quality and the world’s increasing demand for clean water, the need for cheap, easy and portable techniques to characterize and quantify pollutants in waters is urgent. Hence, surface-enhanced Raman spectroscopy (SERS) have gained considerable attention in this field. READ MORE

5. 4. Electromagnetic Phase Engineering With Metamaterials

   University essay from KTH/Tillämpad fysik

   Author : Olof Sjödin; [2021]
   Keywords : Applied Physics; Electromagnetism; Metamaterials; MIM; Plasmonics; FEM; Reflector design; Phase engineering; Tillämpad fysik; Elektromagnetism; Metamaterial; MIM; Plasmonics; FEM; Reflektor design; Fasdesign;

   Abstract : Metamaterials are artificially designed materials with desired electromagneticresponses for advanced wave manipulation. Their key constituent is often somenoble metal, thanks to its well localized plasmonic effects with highextinction cross section. READ MORE

6. 5. Quantification using SERS on a colloidal substrate

   University essay from Uppsala universitet/Fasta tillståndets fysik

   Author : Kasper Eliasson; [2021]
   Keywords : SERS; spectrometry; nano technology; plasmonics;

   Abstract : This thesis explores the practical usefulness of surface enhanced Raman spectroscopy on a colloidal substrate for quantification of organic analytes in a water matrix. The method evaluated is very simple and accessible as it utilizes a commercially available hand held Raman spectrometer and citrate reduced silver colloid substrate. READ MORE
