  2. 21. In-situ TEM Probing of Nanomaterials

    Author : Magnus Hummelgård; Håkan Olin; Valeria Nicolosi; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanotechnology; in situ; TEM; probing; nanowires; nanoparticles; ink; Other engineering physics; Övrig teknisk fysik; Material physics with surface physics; Materialfysik med ytfysik; Condensed matter physics; Kondenserade materiens fysik;

    Abstract : Nanomaterials because of their small size, may have special properties unlikely to be seen in ordinary types of materials. Nanomaterials like nanotubes,nanowires and nanoparticles are best studied at the nanoscale, vital but also problematic. READ MORE

  4. 22. Use of Cellulose for the Preparation of Capsules and Beads with Molecularly Tailored Properties

    Author : Katarzyna Mystek; Lars Wågberg; Bernard Cathala; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; regenerated cellulose; partially modified cellulose; capsules; beads; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The continuously increasing global production of petroleum-based polymers to meet the ever growing demand for plastics for use in a multitude of industrial sectors (e.g. packaging and textiles) has an impact on human health, climate change and the entire ecosystem. READ MORE

  5. 23. Highly Concentrated Electrolytes for Lithium Batteries : From fundamentals to cell tests

    Author : Viktor Nilsson; Kristina Edström; Patrik Johansson; Erik Berg; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; SEI; Highly concentrated electrolyte; Al corrosion; Li metal battery;

    Abstract : The electrolyte is a crucial part of any lithium battery, strongly affecting longevity and safety. It has to survive rather severe conditions, not the least at the electrode/electrolyte interfaces. READ MORE

  6. 24. Size Characterisation of Water-Soluble Polymers Using Asymmetrical Flow Field-Flow Fractionation

    Author : Bengt Wittgren; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi-angle light scattering; molar mass distribution; aggregation; size characterisation; Asymmetrical flow FFF; water-soluble polymers; polysaccharides; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Size, as expressed by molar mass, radius of gyration or hydrodynamic radius, for example, is a fundamental parameter of polymers in solution. Thus, there is a strong need for the characterisation of both the size and shape of polymers, particularly of those utilised in various industrial applications. READ MORE

  7. 25. Organization of Nanoparticles in Solution-A TEM Study

    Author : Olivier Balmes; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materiallära; materialteknik; Material technology; organisation; plunge freezing; TEM; nanoparticle; transmission electron microscopy;

    Abstract : A new approach to the study of nanoparticle systems has been introduced. Nanoparticle systems in aqueous and organic solutions have been synthesized and studied by transmission electron microscopy. These systems include nanoparticles of gold, silver, palladium, ruthenium, and platinum which have been stabilized using various ligands. READ MORE
