    Sammanfattning : The search for alternate and renewable energy resources as well as the efficient use of energy and development of such systems that can help to save the energy consumption is needed because of exponential growth in world population, limited conventional fossil fuel resources, and to meet the increasing demand of clean and environment friendly substitutes. Hydrogen being the simplest, most abundant and clean energy carrier has the potential to fulfill some of these requirements provided the development of efficient, safe and durable systems for its production, storage and usage.

  3. 23. Mechanical Pulp-Based Nanocellulose Processing and applications relating to paper and paperboard, composite films, and foams

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Sinke Henshaw Osong; Per Engstrand; Sven Norgren; Mark Martinez; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical pulp; thermo-mechanical pulp; chemi-thermomechanical pulp; fractionation; fines; homogenisation; nanocellulose; nano-ligno-cellulose; microfibrillated cellulose; nanofibrillated cellulose; paper; strength properties; crill; TEMPO; nanographite NG ; composite films;

    Sammanfattning : This thesis deals with processing of nanocellulose originating from pulps, with focus on mechanical pulp fibres and fines fractions. The nanocellulose materials produced within this research project were tested for different purposes ranging from strength additives in paper and paperboard products, via composite films to foam materials.

  4. 24. Rheological and mechanical properties of systems containing nanocellulose

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Tobias Moberg; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shear rheology; Cellulose nanocrystals; Cellulose nanofibrils; Mechanical properties; Dynamic-mechanical analysis; Composites; Extensional rheology;

    Sammanfattning : Nanocellulose is a cellulose entity at the nanoscale. There are several different types of nanocellulose such as cellulose nanofibrils (CNF), which are long, somewhat flexible fibrils and cellulose nanocrystals (CNC), which are shorter and more rod-like particles. LÄS MER

  5. 25. Environmentally adapted lubricants properties and performance

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Anders Pettersson; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : The lubricants of the future have to be more environmentally adapted, show a higher level of performance, and give a lower total life cycle cost (LCC) than the lubricants that are used today. One way to be able to produce, choose and formulate these lubricants is to have good knowledge about the properties of the base fluids and their additive response. LÄS MER
