  1. 16. Multifunctional magnetic materials prepared by Pulsed Laser Deposition

    Author : Sandeep Nagar; Lyuba Belova; K. Venkat Rao; Prashanth Kamath; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic materials; thin films; pulsed laser depsoition; spintronics; chromites; MgO; NEMS; MEMS;

    Abstract :      Pulsed LASER deposition (PLD) is widely recognized as excellent deposition technique owing to stoichiometric transfer of target material, easy preparation and high quality. Thin films from few nanometers to micrometer regime can be fabricated with equal ease. READ MORE

  2. 17. Fabrication of nanocellulose-based materials : Liquid crystalline phase formation and design of inorganic–nanocellulose hybrids

    Author : Christina Schütz; Lennart Bergström; Germán Salazar-Alvarez; Mark MacLachlan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materials Chemistry; materialkemi;

    Abstract : The increasing need to replace fossil fuels as a source of energy and raw material is resulting in extensive research efforts towards identifying and developing high performance materials and devices based on renewable sources. Cellulose being the most versatile and abundant biopolymer in nature is one of the obvious choices. READ MORE

  3. 18. Nanoplasmonic Alloy Hydrogen Sensors

    Author : Ferry Nugroho; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indirect nanoplasmonic sensing; plasmonic sensors; hydrogen sensors; polymers; fiber optics; nanofabrication; localized surface plasmon resonance; alloy nanoparticles; carbon capture and storage; sensors; palladium;

    Abstract : The hydrogen economy proposes hydrogen gas as the main energy carrier thanks to its high energy density and the possibility to produce it in a sustainable way without CO2 emission. However, the wide flammability range of hydrogen-air mixtures dictates that hydrogen sensors will be a mandatory accessory to any appliance or vehicle fueled by hydrogen. READ MORE

    Abstract : Coil coatings are durable  organic coatings used to protect metal sheets from corrosion and improve their aesthetic properties. Because of their extensive use, coil coatings have long been of interest for industrial and academic researchers. READ MORE

  5. 20. Preparation and optical characterisation of antireflection coatingsand reflector materials for solar energy systems

    Author : Per Nostell; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Abstract : An angle-resolved scatterometer and an integrating sphere for reflectance measurements at oblique angles of incidence have been designed and evaluated. The integrating sphere has a centre-mounted sample holder and the detector sits at the end of the sample holder and therefore always faces the same sphere wall area. READ MORE
