2. 1. Grain Size and Solid Solution Strengthening in Metals

   Author : Dilip Chandrasekaran; KTH; []
   Keywords : strengthening mechanisms; flow stress; solid solution strengthening; grain size strengthening; micromechanical modelling; AFM; EBSD;

   Abstract : The understanding of the strengthening mechanisms is crucialboth in the development of new materials with improvedmechanical properties and in the development of better materialmodels in the simulation of industrial processes. The aim ofthis work has been to study different strengthening mechanismsfrom a fundamental point of view that enables the developmentof a general model for the flow stress. READ MORE

7. 5. Molecular Interactions in Thin Films of Biopolymers, Colloids and Synthetic Polyelectrolytes

   Author : Johansson Erik; Lars Wågberg; Andreas Fery; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polyelectrolyte multilayers; Layer-by-Layer assembly; Adhesion; Adsorption; Young s modulus; Mechanical buckling; AFM; JKR; SPAR; QCM-D; SIEBIMM; PAH; PAA; Starch; NFC; Nanocellulose;

   Abstract : The development of the layer-by-layer (LbL) technique has turned out to be an efficient way to physically modify the surface properties of different materials, for example to improve the adhesive interactions between fibers in paper. The main objective of the work described in this thesis was to obtain fundamental data concerning the adhesive properties of wood biopolymers and LbL films, including the mechanical properties of the thin films, in order to shed light on the molecular mechanisms responsible for the adhesion between these materials.
