1. 16. Rheology and Microstructure of Mixed Biopolymer Gels

   Författare :Leif Lundin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carrageenan; microstructure; rheology; xanthan; PCA; polysaccharide mixture; locust bean gum; transmission electron microscopy TEM ; multivariate analysis; viscoelastic measurements; PLS;

   Sammanfattning : The viscoelastic behaviour of biopolymer mixtures showing synergism was investigated under different physicochemical conditions using small deformation oscillatory measurements. In addition, the rheological properties of binary polysaccharide mixtures were related to the microstructure as observed using transmission electron microscopy. LÄS MER

3. 17. Theoretical and Experimental Studies of Polymer Adsorption and Polymer Mediated Interactions

   Författare :Fei Xie; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte; Adsorption; Colloid; Polymer; Dispersion; Interation; Ellipsometry; Monte Carlo Simulation; Classical Density Functional Theory;

   Sammanfattning : Polyelectrolyte adsorption and polymer mediated interactions in different colloidal polymer systems have been studied in this work. Theoretical methods and experimental techniques are combined, in order to obtain more general reliable results, as well as a deep understanding of the molecular mechanisms that are responsible for the observed behaviors.

   Sammanfattning : Cellulose has for a long time been used by man. It is renewable and an easily recyclable resource. Mostly it has been used in either its native form as wood or in the form of fibres. LÄS MER

5. 19. The dielectric properties of solid biofuels

   Författare :Ana Marta Paz; Erik Dahquist; Ebbe Nyfors; Mälardalens högskola; []
   Nyckelord :dielectric properties; solid biofuels; moisture content determination; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : The use of bioenergy has been increasing due to efforts in fossil fuels replacement. Modern bioenergy technologies aim for high efficiency and low pollution levels, which increases the need for methods for the on-line characterization of biofuels. LÄS MER

7. 20. Interfacial Adhesion Failure : Impact on print-coating surface defects

   Författare :Hajer Kamal Alm; Lars Wågberg; Göran Ström; Janet Preston; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ink-paper coating adhesion; offset printing; calcium carbonate pigments; polyacrylate; dispersant; print mottle; surface chemistry; hygroscopy of surfaces; coating structure; print quality; water interference mottle; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER
