  2. 11. Recirculation of scrapped resources : The role of material information in enhancing the sustainability of recycling

    Author : Reinol Josef Compañero; Andreas Feldmann; Peter Samuelsson; Pär Jönsson; Guozhu Ye; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel recycling; anthropogenic resources; scrap; value of information; Circular Economy; sustainability; Stål återvinning; antropogena resurser; skrot; cirkulär ekonomi; hållbarhet; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : Industries have responded to the climate change problem by positioning their activities as compatible with concepts such as the Circular Economy. Conveying the idea of maximizing and keeping the resources in a manner that aligns with the principles of sustainable development, the endorsements for implementing circularity measures has arguably become a boon for businesses.

  4. 12. Control of Dynamically Assisted Phase-shifting Transformers

    Author : Nicklas Johansson; Hans-Peter Nee; Olof Samuelsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thyristor Controlled Series Capacitor; Thyristor Switched Series Capacitor; Controlled Series Compensator; Dynamic Power Flow Controller; Phase-Shifting Transformer; Power Oscillation Damping; Transient Stability; Power Flow Control; Adaptive Control; Electric power engineering; Elkraftteknik;

    Abstract : In this thesis, controllers for power oscillation damping, transient stability improvement and power flow control by means of a Controlled Series Compensator (CSC) and and a Dynamic Power Flow Controller (DPFC) are proposed. These devices belong to the group of power system components referred to as Flexible AC Transmission System (FACTS) devices. READ MORE

  5. 13. Functional proteomics of protein phosphorylation in algal photosynthetic membranes

    Author : Maria Turkina; Peter Strålfors; Göran Samuelsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein phosphorylation; mass spectrometry; photosynthesis; proteomics; Biochemistry; Biokemi;

    Abstract : Plants, green algae and cyanobacteria perform photosynthetic conversion of sunlight into chemical energy in the permanently changing natural environment. For successful survival and growth photosynthetic organisms have developed complex sensing and signaling acclimation mechanisms. READ MORE

  6. 14. Decarbonising the Stainless Steelmaking through Alloy Solutions

    Author : Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. READ MORE

  7. 15. Assessment of Raw Materials in Stainless Steelmaking-Their Energy Consumption and Greenhouse Gas Emission

    Author : Wei Wenjing; Anders Tilliander; Peter Samuelsson; Pär Jönsson; Ye Guozhu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static process model; mass and energy balance; molybdenum; nickel; phosphorus; stainless steel; life cycle assessment; GHG emission; energy consumption; statisk procesmodell; mass- och energibalans; molybden; nickel; fosfor; rostfritt stål; livscykelanalys; växthusgasutsläpp; energiförbrukning; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : In stainless steelmaking, around 68% of the total greenhouse gas emissions come from the processing of raw materials. Thus, it is important for steelmakers to make efforts together with their raw material suppliers to implement low-carbon initiatives. To facilitate such initiatives, assessment of raw materials will provide guidance. READ MORE
