  4. 2. Reversible Sulfur Reactions in Pre-Equilibrated and Catalytic Self-Screening Dynamic Combinatorial Chemistry Protocols

    Author : Rikard Larsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamic Combinatorial Chemistry; Reversible sulfur reactions; Catalytic self-screening; Carbohydrates; Lectins; Quartz Crystal Microbalance; Organic chemistry; Organisk kemi;

    Abstract : Dynamic Combinatorial Chemistry (DCC) is a recently introduced supramolecular approach to generate dynamically interchanging libraries of compounds. These libraries are made of different building blocks that reversibly interact with one another and spontaneously assemble to encompass all possible combinations. READ MORE

  5. 3. Titanium-Based Negative Electrode Materials for Rechargeable Batteries : In Search of the Redox Reactions

    Author : Tatiana Koriukina; Kristina Edström; Egbert Figgemeier; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; sodium-ion batteries; MXenes; perovskite oxides; redox reactions; XPS; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Rechargeable batteries, particularly, lithium-ion batteries (LIBs) have proven to be stable and reliable energy storage devices over the past few decades. The rapid demands regarding battery applications and the pressure to move away from the fossil fuel era drive the search for new materials for better rechargeable batteries for electric vehicles, renewable energy storage, and portable electronics.
