1. 1. Fabrication of sub-10 nm solid-state nanopores by electrical breakdown

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Kasumi Tsutsumi; [2023]
   Nyckelord :Nanopore fabrication; Solid-state material; Silicon nitride; Graphene; DNA translocation; Nanopor-avkänning; fast tillståndsmaterial; kiselnitrid; grafen; DNA-translokation;

   Sammanfattning : Nanopore sensing is a versatile technique that employs very small openings, known as nanopores, to study biomolecules. The use of nanopores on solid-state membranes has gained attention due to its potential for low-cost and high-throughput sensing of single molecules in liquids. LÄS MER

3. 2. Techno-Economic Assessment of a Post-Combustion CO2 Capture Unit in SCA Östrand Pulp Mill

   Master-uppsats, KTH/Energiprocesser

   Författare :Abhishek Subramani; [2022]
   Nyckelord :Bioenergy with Carbon Capture and Storage; Post-Combustion Capture; Monoethanol Amine; Chilled Ammonia; Techno-Economic Assessment;

   Sammanfattning : The Paris Agreement has ambitious targets to limit the global warming below 1.5 °Cin the 21st century. This goal is reflected in the national climate targets, for example, Sweden aims to achieve net zero greenhouse gas emissions by 2045, and thereafter achieve negative emissions. LÄS MER

4. 3. Strategies for regional deployment of hydrogen infrastructure : The case of North Rhine-Westphalia, Germany

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Roberto Di Molfetta; [2022]
   Nyckelord :Hydrogen; Infrastructure rollout; Supply chain pathways; Mobility; Hydrogen buses.;

   Sammanfattning : In response to the growing urge towards decarbonisation, more and more initiatives have been set to reduce and/or compensate the level of CO2 (carbon dioxide) emitted by human activities, which is one of the main responsible of the incumbent threats of “global warming” and “climate change”. “Climate neutrality by 2050” has become a decisive topic for political agendas worldwide and, against that background, the hydrogen economy can play a significant role.

5. 4. Stochastic Goal Programming of Supply Chain under Disruption

   Master-uppsats, KTH/Industriell ekonomi och organisation (Inst.)

   Författare :Chinmayi Desai; [2022]
   Nyckelord :Stochastic goal programming; COVID; supply disruption; supply chain resilience; China plus one; Stokastisk målprogrammering; COVID; försörjningsavbrott; motståndskraftig leveranskedja;

   Sammanfattning : The spread of COVID-19 pandemic in the world and the importance of controlling it in all regions have made managing this crisis a great challenge for all countries. The devastating effect on global automotive supply chains due to the disruptions has resulted in losses and shut down of production facilities owing to government restrictions due to the spread of infections leading to supply breakdown across all tiers of supply chain.

7. 5. Characterisation of GaN HEMTs on Different Substrates for Power Electronics Applications

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Hithiksha Krishna Murthy; [2022]
   Nyckelord :Gallium nitrate; High Mobility Electron Transistor; Silicon carbide; Silicon; Sapphire; substrates; power electronics;

   Sammanfattning : GaN-based High Electron Mobility Transistors (HEMT) are appealing because of their large breakdown field, high saturation velocity, and superior thermal conductivity. They work at high temperature without much degradation. HEMTs have a few drawbacks despite many positives. The cost of developing GaN HEMTs on a native substrate is high. LÄS MER
