11. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors
University essay from KTH/Tillämpad fysikAbstract : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. READ MORE

12. Double-layer vs single-layer cryogels as a dye affinity chromatography column, comparison study
University essay from Lunds universitet/Kemiska institutionenAbstract : Dye affinity chromatography is one of the chromatography techniques which uses dye as a ligand for protein purification. In this study, single-layer poly(acrylamide-allyl glycidyl ether) cryogel was prepared, which contains free epoxy groups at sub-zero temperature. READ MORE

13. Charge transfer states at polymer solar cell interfaces : Insights from atomic-scale modeling
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

14. Synthesis of Graphene - Carbon Nanotube Hybrid Structures
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Graphene and Carbon nanotubes (CNTs) have been researched for more than a decade due to their extraordinary properties and advantages towards applications like electronics, structural re-enforcements, thermal management and energy storage. Graphene-CNT hybrid structures have been predicted to further enhance the exceptional properties and overcome some of the shortcomings of the individual materials. READ MORE

15. Photoredox catalysis enabled C–O bond activation: Access to unnatural amino acids
University essay from KTH/KemiAbstract : Fotoredoxkatalys tillhandahåller möjligheter att utveckla nya hållbara kemiska reaktionsvägar. När fotokatalysatorn bestrålas med synligt ljus möjliggörs elektronöverföring till eller från substratet som i sin tur medför alstring av reaktiva fria radikaler. READ MORE
