  1. 1. Foaming of cellulose derivatives and hemicellulose-containing materials

    Author : Kristina Karlsson; Chalmers University of Technology; []
    Keywords : β-glucan; arabinoxylan; scale-up production; hydroxypropyl methylcellulose HPMC ; ethyl hydroxyethyl cellulose EHEC ; hot-mould foaming; extensional viscosity; extrusion; hemicellulose; rheological characterisation; Foaming; xylan; cellulose derivatives;

    Abstract : Fossil-based polymeric foams are important materials due to their good mechanical properties relative their low density, the low price and the possibility for large-scale production. They are widely used in cushioning, absorbing and insulation applications. There are however a few disadvantages with these foamed products. READ MORE

  2. 2. Surface Chemistry Studies on Surfactant Properties Relevant to Flotation De-inkin

    Author : Katarina Theander; KTH; []
    Keywords : de-inking; sodium oleate; nonionic surfactant; surface tension; foaming;

    Abstract : The objective of this work was to investigate thephysico-chemical properties of common de-inking chemicals. Thishas been done by means of equilibrium and dynamic surfacetension measurements as well as foaming experiments. READ MORE

  3. 3. Rapid sintering of ceramics by intense thermal radiation

    Author : Duan Li; Zhijian Shen; Lutz-Michael Berger; Stockholms universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Sintering; sintering by intense thermal radiation; spark plasma sintering; heat transfer; mass transfer; scattering; coalescence; densification; grain growth; numerical simulation; porous ceramic; foaming; nanostructure; hierarchical heterogeneities; permeability; Materials Chemistry; materialkemi;

    Abstract : Sintering is an important processing step for obtaining the necessary mechanical stability and rigidity of ceramic bulk materials. Both mass and heat transfer are essential in the sintering process. The importance of radiation heat transfer is significantly enhanced at high temperatures according to the well-known Stefan-Boltzmann’s law. READ MORE
