1. 1. Investigations of thermophysical properties of slags with focus on slag-metal interface

   Författare :Luckman Muhmood; Seshadri Seetharaman; Nurni Neelakandan Viswanathan; Allan Cramb; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slags; density; diffusivity; sessile drop; interfacial velocity; interfacial viscosity; interfacial dilatational modulus; interfacial shear viscosity; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. LÄS MER

3. 2. 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

5. 4. Poly(Ethylene Oxide) Based Bottle-Brush Polymers and their Interaction with the Anionic Surfactant Sodium Dodecyl Sulphate : Solution and Interfacial Properties

   Författare :Joseph Iruthayaraj; Per M. Claesson; Regine v. Klitzing; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEO brush polymers; brush polymers; PEO; poly ethylene oxide ; polymer-surfactant; sodium dodecyl sulphate SDS ; Ellipsomtery; PEO-SDS interactions; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : The aim of this thesis work is to study the physico-chemical properties of poly(ethylene oxide), PEO, based brush polymers both in solution and at solid/aqueous interfaces. The importance of studying the surface properties of brush polymers can be related to a broad spectrum of interfacial-related applications such as colloidal stability, lubrication, detergency, protein repellency to name a few.

7. 5. Interfacial kinetic ski friction

   Författare :Leonid Kuzmin; Mats Tinnsten; Jonas Danvid; Mikael Jonsson; Roland Larsson; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ski glide; ski base; ski wax; hydrophobicity; UHMWPE; PTFE; topography; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : It is no doubt, that the ski glide over the snow is a very complicated object of research. However, ski glide is just a one area of many other areas of human knowledge. As a rule, the scientists and practitioners, who work in these areas, operate with some publicly expressed more or less solid hypotheses. LÄS MER
