  1. 1. A toolbox for improving the processability of composites with a high content of thermomechanical pulp

    Författare :Seyedehsan Hosseini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interface.; thermomechanical pulp; magnesium stearate; mechanical properties; composite; molybdenum disulfide; AKD;

    Sammanfattning : The use of oil-based products causes large volumes of non-biodegradable waste and contributes to climate changes. Focus has consequently shifted towards the use of polymers derived from wood. The processability of such polymers, however, presents a challenge but this can be overcome through the use of composite materials, i.e. LÄS MER

    Sammanfattning : Efforts to address environmental concerns have resulted in new regulations designed to plan the reduction of plastic and synthetic polymer usage, necessitating the search for sustainable natural alternatives with comparable cost-effectiveness and mechanical performance. Thermomechanical pulp (TMP) fibres are one of the most affordable natural fibres that have no chemical refining in production, production have a high yield of 90-98% and TMP fibres have been demonstrated to improve the mechanical characteristics (strength, stiffness and toughness) of wood-polymer composites (WPCs) compared to the pure polymer.

  4. 3. Interfacial and material aspects of powders with relevance to pharmaceutical tableting performance

    Författare :Maria Badal Tejedor; Mark W. Rutland; William Ducker; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atomic force microscopy; excipients; surface characterization; tableting; milling; amorphisation; Kemi; Chemistry;

    Sammanfattning : Tablets are the most common forms of drug administration. They are convenient to administer and easy to manufacture. However, problems associated with the adhesion of the powders to the tableting tools are common. This phenomenon is known as sticking and even though it has been well documented and studied, it remains poorly understood. LÄS MER
