  1. 1. 3D Coating of Interface Materials for High-Performance RF Passive Devices

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Xiner Shen; [2023]
    Keywords : Ceramic coating; Dip coating; Radio frequency; Passive RF devices; Quality factor; Keramisk beläggning; Dip-beläggning; Radiofrekvens; Passiva RF-enheter; Kvalitetsfaktor;

    Abstract : The demand for high-performance Radio Frequency (RF) passive devices has been steadily increasing due to the growing complexity and sophistication of wireless communication systems. The Quality factor (Q-factor) is a key parameter for describing the signal losses and the energy efficiency of resonators. READ MORE

  3. 2. Towards laser fabrication of soft neural electrodes

    University essay from Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Author : John Schill; [2022]
    Keywords : Stretchable electrodes; UV-laser ablation; Silver nanowires; 355 nanoseconds laser; electrode patterning; Teknisk biologi; Teknisk biologi;

    Abstract : Electronic devices define our everyday lives. They are often large, rigid, and brittle. Modern medical science has come so far as to start using miniature electronic devices to monitor many types of diseases. READ MORE

  4. 3. 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

  5. 4. Oxygen Reduction Catalysts in Alkaline Electrolyte

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Avital Cherednik; Anders Abrahamsson; Bjarne Falk; [2020]
    Keywords : Alkaline Fuel Cells; Catalyst; Silver; Nano Particles; Radiolysis; Gamma-radiation;

    Abstract : Alkaline fuel cells are a promising technology, with their sturdy design and many applications they are held back mostly by their cost. By introducing a catalyst, the activation energy of the cell can be reduced to an overcomable amount. READ MORE

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

    University essay from Uppsala universitet/Materialteori

    Author : Simon Moberg; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE
