1. 1. Birch leaf carbon dots: characterization and application in a light-emitting electrochemical cell

   University essay from Umeå universitet/Institutionen för fysik

   Author : Märta Gregorsson; [2022]
   Keywords : carbonized polymer dot; carbon dots; light-emitting electrochemical cell; pheophytin; solid-state luminescence; self-quenching; aggregation-caused-quenching; host-guest system;

   Abstract : A new rising star in the carbon nanomaterial family is carbon dots. Carbon dots have received great attention due to their excellent luminescence and low toxicity. In this project, a new carbon dot derived from birch leaves is studied and characterized. READ MORE

3. 2. Techno-economic feasibility for residential Local Energy Communities: Case study of Italy

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Linda Colarullo; [2021]
   Keywords : Local Energy Community; Energy Sharing; Italy; Virtual Regulation Model; Distributed Renewable Energy Resources; Self-consumption maximization; Demand Side Management;

   Abstract : The use of renewable energy has proven to be essential for the decarbonisation of the energy system, bringing changes on both the production and consumption side, with an increase of renewable energy in the mix and a change in the role of consumers. From passive actors, Consumers are becoming Prosumers (producers and consumers) of self-generated energy, with the potential of becoming the pillar of the energy sector transition. READ MORE

4. 3. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

   University essay from Umeå universitet/Institutionen för fysik

   Author : Thomas Moberg; [2018]
   Keywords : Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

   Abstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE
