  2. 1. Synthesis of Nanoparticles and Organometallic Complexes for Gas Sensing

    Author : Alicja Stolas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanocube; LSPR; alloys; colloidal synthesis; organic synthesis; phthalocyanine complexes; gas sensing.; stabilizers; palladium; nanoparticles; phthalocyanine; nanocomposites; gold;

    Abstract : Currently metal nanoparticles (NPs) are a subject of interest regarding many applications, in particular chemical gas sensing, as the associated environmental issues are of substantial importance. Metal NPs are attractive due to their fascinating optical properties and primarily, localized surface plasmon resonance (LSPR) which strongly depends on size and shape of NPs. READ MORE

  4. 2. Toward Safer Energy Storage Solution by Development of Fluorine-Free Battery Electrolyte

    Author : Elham Hosseini Bab Anari; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries SIBs ; aqueous electrolyte; lithium-ion batteries LIBs ; safer electrolyte; fluorine-free salt;

    Abstract : Portable electronic devices such as mobile phones, laptops, cameras and electronic vehicles (EVs) which contain lithium-ion batteries (LIBs), are indispensable part of our modern society. The safety of conventional electrolytes of LIBs, composed of fluorinated lithium salts and organic solvents is the source of some concerns. READ MORE

  5. 3. Synthesis of protic ionic liquids. Challenges and solutions for the synthesis of pure compounds

    Abstract : The common European Energy and Climate policy states that in 2020 the share of biofuels for inland transports should be 10 %. Such a stipulation calls for a commercially sustainable biofuel production. READ MORE

  7. 5. Facilitating electron transfer in bioelectrocatalytic systems

    Author : Alina Sekretaryova; Mats Eriksson; Mikhail Vagin; Anthony Turner; Evgeny Katz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Bioelectrocatalytic systems are based on biological entities, such as enzymes, whole cells, parts of cells or tissues, which catalyse electrochemical processes that involve the interaction between chemical change and electrical energy. In all cases, biocatalysis is implemented by enzymes, isolated or residing inside cells or part of cells. READ MORE
