1. Sublimation temperature prediction of OLED materials : using machine learning
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analys och partiella differentialekvationerSammanfattning : Organic light-emitting diodes (OLED) are and have been the future of display technology for a minute. Looking back, display technology has moved from cathode-ray tube displays (CRTs) to liquid crystal displays (LCDs). Whereas CRT displays were clunky and had quite high powerconsumption, LCDs were thinner, lighter and consumed less energy. LÄS MER
2. Creating nanopatterned polymer films for use in light-emitting electrochemical cells
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : 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. LÄS MER
3. Surface energy modification of metal oxide to enhance electron injection in light-emitting devices : charge balance in hybrid OLEDs and OLETs
Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskapSammanfattning : Organic semiconductors (OSCs) present an electron mobility lower by several orders of magnitude than the hole mobility, giving rise to an electron-hole charge imbalance in organic devices such as organic light-emitting diodes (OLEDs) and organic light-emitting transistors (OLETs). In this thesis project, I tried to achieve an efficient electron transport and injection properties in opto-electronic devices, using inorganic n-type metal oxides (MOs) instead of organic n-type materials and a polyethyleneimine ethoxylated (PEIE) thin layer as electron transport (ETLs) and injection layers (EILs), respectively.

4. Synthesis and Reactivity of N-heterocyclic Gold (I) Complexes
Master-uppsats, Lunds universitet/Kemiska institutionenSammanfattning : Populärvetenskaplig sammanfattning Metallorganisk kemi är en gren av kemin som fokuserar på att utveckla nya reaktioner med hjälp av övergångsmetaller som t.ex. järn, kobolt och guld. Genom att använda övergångsmetaller i kemi är det möjligt att bilda nya reaktioner som man med konventionell organisk kemi inte kan få tillgång till. LÄS MER
5. Dyeing of Wool and Silk Fibres with a Conductive Polyelectrolyte and Comparing Their Conductance
Magister-uppsats, Högskolan i Borås/Institutionen TextilhögskolanSammanfattning : Polyelectrolytes are conductive polymers because of their ionic side group and PEDOT-S is one of those conductive polyelectrolytes. Previously, recombinant silk fibre has been dyed with PEDOT-S. PEDOT-S showed that it can be dyed with recombinant silk fibre over a very wide range of pH from 11 to 1.7. LÄS MER
