1. 6. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

   Master-uppsats, Lunds universitet/Centrum för analys och syntes

   Författare :Salim Charkas; [2023]
   Nyckelord :Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

   Sammanfattning : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

   Nyckelord :Dataanalysverktyg;

   Sammanfattning : 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. LÄS MER

4. 8. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

   Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

   Författare :Natachai Terawatsakul; [2023]
   Nyckelord :;

   Sammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER

   Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER
