2. 16. Steric Stabilization of Polylactide particles achieved by Covalent 'grafting-from' with Hydrophilic Polymers

   Author : Robertus Wahyu Nayan Nugroho; Ann-Christine Albertsson; Karin Odelius; Anders Höglund; Mark Rutland; Martina Janstål; KTH; []
   Keywords : Steric stabilization; AFM; hydrophilicity; surface modification; poly lactide ; acrylamide; acrylic acid; maleic anhydride;

   Abstract : Despite numerous advantages of using particles in a wide range of applications, they have one drawback that is their tendency to agglomerate. One way to overcome this problem is to sterically  stabilize the particles by introducing polymeric  chains covalently attached to the surface. READ MORE

4. 17. Self Assembly at the Liquid Air Interface

   Author : Niga Petru; Rutland Mark; Ye Shen; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; VSFS; SFG; interface; crown ethers; ethylene oxides; ionic liquids; fatty acids; domains.; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : The aim of this work is to study the interfacial properties of amphiphilic compounds at the liquid–air interface in an attempt to develop a comprehensive understanding of their orientation as well as the influence of their interaction with the solvent on the interfacial layer properties. Using Vibrational Sum Frequency Spectroscopy (VSFS) as the main tool, the molecular structure of the amphiphilic layer and the amphiphile–solvent relation can be illuminated in great detail – it is arguably the most sensitive surface spectroscopy currently available.

5. 18. Sustainable Lubrication and Tribotronics enabled by Ionic Materials

   Author : Akepati Bhaskar Reddy; Sergei Glavatskih; Mark W. Rutland; Nicholas Spencer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable lubrication; ionic liquid; tribotronics; lubricating grease; neutron reflectance; Machine Design; Maskinkonstruktion;

   Abstract : Developments in machine design play a crucial role in the global endeavor towards sustainability. The potential for energy conservation and emission reduction has pushed lubrication research to the forefront, with the lubricant considered to be a vital machine component. READ MORE

6. 19. Water-based Flexographic Printing on Polymer-coated Board

   Author : Maria Rentzhog; Mark Rutland; Joseph Aspler; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : This doctoral thesis comprises three studies dealing with water-based flexography on polymer-coated boards, which have been presented in the five papers included at the end of the thesis. The first study (covered in three papers) presents results from characterisation of a matrix of water-based inks with respect to their rheology, surface tension, wetting, and fulltone printing performance on PE-coated board.

7. 20. Lubrication mechanisms and properties of non-halogenated orthoborate ionic liquids

   Author : Patrick Rohlmann; Sergei Glavatskih; Mark W. Rutland; Oleg N Antzutkin; Ali Erdemir; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ionic Liquids; Friction; Wear; Viscosity; Density; Additive; Machine Design; Maskinkonstruktion;

   Abstract : One way to reduce energy consumption and waste - a necessity to achieve the UN-mandated limitation of average global temperature in-creases - is to select suitable lubricants so that energy-losses through friction and wear are minimised. In this context, non-halogenated ionicliquids (ILs) are promising candidates to achieve this aim due to their intrinsic ionic properties, low vapour pressure and high thermal stability. READ MORE
