  2. 16. Tabletting behaviour of aggregates : Mechanistical conception and modulation by variations in aggregate physical properties

    Author : Barbro Johansson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Abstract : The volume reduction mechanisms involved during compression of aggregates prepared from microcrystalline cellulose particles and effects of variations in their physical properties on their compression behaviour and compactability were studied in this thesis.The dominating volume reduction mechanisms during compression of aggregates prepared of MCC were deformation (bulk deformation and local deformation) parallel with densification, and generally the degree of fragmentation of the aggregates was minute.

  4. 17. A Mathematical and Experimental Study of Inclusion Behaviour at a Steel-Slag Interface

    Author : Jenny Wikström; Pär Jönsson; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical modeling; inclusion separation; tundish; ladle; slag; steel-slag interface; CSLM experiments; agglomeration; physical properties; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : The aim of this thesis work is to increase the knowledge of inclusion behavior at the steel-slag interface by mathematical modeling and in-situ Confocal Scanning Laser Microscope experiments. Mathematical models based on the equation of motion predicting liquid and solid inclusion behavior was first investigated. READ MORE

  5. 18. Influence of heat on the physical and mechanical properties of selected rock types

    Author : Christine Saiang; Karl-Johan Loorents; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunnel fires; heat influences; temperature increase; mechanical properties; physical properties; micro cracks; mineralogy; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : Impelled by the increase in the number of tunnel fires in the last decade alone, wide spread attention has been drawn towards tunnel fire safety studies. Many of these fires occurred in road and railway tunnels involving vehicles and trains. READ MORE

  6. 19. Covalent Graphene Functionalization for the Modification of Its Physical Properties

    Author : Hu Li; Klaus Leifer; Annick Loiseau; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene; functionalization; nanomechanical property; graphene nanoscroll;

    Abstract : Graphene, a two dimensional monolayer carbon sheet with the atoms tightly packed in a hexagonal lattice, has exhibited so many excellent properties, which enable graphene to break several material records with regard to carrier mobility, strength yield and thermal conductivity to name a few. Therefore, graphene has been placed as a potential candidate to allow truly next-generation material. READ MORE
