    Sammanfattning : Living matter is built on complex dynamic systems consisting of numerus biotransformations. By exploiting the adaptive and evolutive behaviors ofmolecular matter, dynamic chemistry has developed as an important tool tounderstand the organization of nonliving matter into complex living systems.

    Sammanfattning : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. LÄS MER

  4. 3. Dynamic Systems : Enzymatic Synthesis, Exchange Reactions and Applications in Materials Science

    Författare :Yang Zhang; Olof Ramström; Mihail D. Barboiu; KTH; []
    Nyckelord :constitutional dynamic chemistry; reversible reactions; kinetic resolution; dynamic kinetic resolution; enzyme catalysis; lipase; asymmetric synthesis; racemization; oxazolidinone; organogel; enamine; nitroaldol reaction.;

    Sammanfattning : This thesis is divided into three parts, revolving around the developments of dynamic systems utilized in dynamic kinetic resolution (DKR) and constitutional dynamic chemistry (CDC).The first section gives an introduction to constitutional dynamics, the core concept of this thesis.

  5. 4. Resolution of Dynamic Systems: Applications in Asymmetric Synthesis and Materials Science

    Författare :Lei Hu; Olof Ramström; Douglas Philp; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : This thesis is built on the concepts of constitutional dynamic chemistry and dynamic kinetic resolution, where reversible covalent reactions are used to generate dynamics and kinetically controlled reactions are employed for resolution. The thesis is divided into two parts:The first section focuses on the study of dynamic systemic resolution, a concept derived from constitutional dynamic chemistry. LÄS MER

  7. 5. Caste transformation. A case study on Vellalah identity in relation to the Tamil nation project in Jaffna, Sri Lanka

    Författare :Bahirathy Jeeweshwara Räsänen; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Vellalah identity; nation project; Tamils; caste; transformation; narratives; identification premise; Jaffna; cultural schema; mental structure; LTTE; war; Sri Lanka;

    Sammanfattning : The study explores the meanings and practices associated with Vellalah identity in relation to the Tamil nation project in Jaffna, in the northern part of Sri Lanka, with a focus on caste transformation. Given that caste is a culturally sensitive identity and practice of Tamils, the inescapable engagement with the Tamil nation project is investigated here via a case study on Vellalah, the protagonist and hegemonic caste among Tamils.
