2. 1. Mechanical Recycling of Engineering Thermoplastics using Alloying Techniques

   Author : Xiaodong Liu; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich injection moulding; recycling; compatibilizer; in-situ compatibilization; engineering thermoplastics; J-integral; toughness; impact modifier;

   Abstract : The aim of this thesis is to indicate routes by which recycled engineering thermoplastics (ETP) can be upgraded using alloying techniques. Recycled ETP have often been subjected to long-term service-induced degradation, so that the residual properties of recycled ETP need to be improved. READ MORE

4. 2. Tailoring the magnetic order in mesoscopic spin systems

   Author : Henry Stopfel; Vassilios Kapaklis; Hjörvarsson Björgvin; Unnar Arnalds; John Cumings; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; artificial spin ice; magnetic nano-structures; mesoscopic spin systems; mesospins; model systems; Shakti; Saint George; interaction modifier; engineering of energy-landscape; multiple energy-scales; Fysik; Physics;

   Abstract : Mesoscopic spin systems can be designed and fabricated using modern nano-fabrication techniques. These systems can contain large numbers of patterned ferromagnetic elements, for which the shape will generally determine their effective mesospin dimensionality. READ MORE

5. 3. Fundamental Investigations of Adsorption in SFC

   Author : Emelie Glenne; Torgny Fornstedt; Jörgen Samuelsson; Caroline West; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supercritical fluid chromatography; SFC; Adsorption isotherm; Excess adsorption isotherm; Solvent adsorption; Peak distortion; Solute retention; Overloaded peaks; Kemi; Chemistry;

   Abstract : In supercritical fluid chromatography (SFC), the eluent is composed by carbon dioxide, often with additional components, in a condition between gas and liquid. This thesis aims to reach a deeper understanding of SFC by revealing the function of the additional eluent components through systematic adsorption studies. READ MORE

6. 4. Energy Saving vs. Performance: Trade-offs in Optical Networks

   Author : Pawel Wiatr; Paolo Monti; Josep Solé-Pareta; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; optical networks; RWA; side-effects; device reliability performance; network performance; operational cost; benefits; loss; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : The energy consumption of communication networks is continuously growing. Many energy saving approaches have been proposed at the device, system, and network level. The most promising way to address this problem is to utilize photonic technologies as much as possible thanks to their low energy consumption per bit performance. READ MORE

7. 5. Studies of electrically conductive textile coatings with PEDOT:PSS

   Author : Maria Åkerfeldt; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; textile coating; conductive coating; conjugated polymers; coating parameters; PEDOT:PSS; Textile technology; Textiles and Fashion General ; Textil och mode generell ;

   Abstract : This study investigates electrically conductive coatings of textiles, obtained with a direct coating and the addition of poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) dispersion to a thickened polyurethane (PU)-based formulation. Textiles with enhanced electrical conductivity have potential applications in antistatic, electrostatic discharge protective, electromagnetic interference shielding, sensoric and temperature-regulating products.
