    Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

  2. 2. Orthoborate Ionic Liquids for Lubricated Interfaces

    Author : Mamoun Taher; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Materials science - Functional materials; Chemistry - Physical chemistry; Chemistry - Organic chemistry; Materials science - Surface engineering; Teknisk materialvetenskap - Funktionella material; Kemi - Fysikalisk kemi; Kemi - Organisk kemi; Teknisk materialvetenskap - Ytbehandlingsteknik; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : The lifespan and efficiency of various types of machinery is often limited by the performance of its lubricated interfaces, which are formed by two interacting surfaces and a lubricant that separates the surfaces to decrease friction and wear. There is a constant quest for more efficient lubricants capable of lubricating non-ferrous surfaces. READ MORE

  3. 3. Interaction of magnetite with soluble silicates and bentonite : implications for wet agglomeration of magnetite concentrate

    Author : Xiaofang Yang; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Physical Chemistry; Fysikalisk kemi; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Iron ore green pellets are produced by agglomeration of moist magnetite concentrates. The quality of green pellets is essential for the transportability and metallurgical benefits of the final product. READ MORE

    Abstract : An ionic liquid (IL) is a salt, which usually is in the liquid state at normal temperature and pressure. The properties of ILs can be adjusted for various processes and applications by choosing different combinations of ions. Similar to other salts, ILs contain only ions with positive (cations) and negative (anions) charges in equal proportions. READ MORE

  5. 5. Adsorption of pinosylvin onto the structure of wood : mechanism and adsorption parameters

    Author : Ildiko Mohammedne Ziegler; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Pinosylvin and polyhydroxybenzene derivatives are natural components of wood, known for their fungicidal/fungistatic properties. These components were used as adsorbates in the present investigation. READ MORE
