2. 1. Different paths to explore confined crystallisation of PCL

   Author : Nima Sanandaji; Ulf W. Gedde; Mikael S Hedenqvist; Javier Martinez de Salazar; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; crystallisation; poly-ε-caprolactone; end groups; morphology; nanoconfinement; melting; monodisperse; RESS; injet printing;

   Abstract : In this work, different paths to confined crystallisation of poly(ε-caprolactone) (PCL) havebeen explored. Innate confinement effects due to the presence of bulky end groups wereshown to affect crystalline characteristics for strictly monodisperse ε-caprolactone oligomers. READ MORE

4. 2. Industrial Digital Fabrication Using Inkjet Technology

   Author : Ingo Reinhold; Carl-Mikael Zetterling; Matti Mäntysalo; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inkjet printing; droplet formation; digital fabrication; sintering; nanoparticles; printed electronics; Industrial Information and Control Systems; Industriella informations- och styrsystem; Media Technology; Medieteknik; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : The use of acoustic waves initiated by the deformation of a microchannel is one method for generating monodisperse, micrometer-sized droplets from small orifices and is employed in piezo-electric inkjet printheads. These printheads are used in both graphical printing and digital fabrication, where functionalities, such as optical, biological, electrical or mechanical, are being produced locally. READ MORE

5. 3. LES of Jets and Sprays Injected into Crossflow

   Author : Mirko Salewski; Strömningsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaser; fluid dynamics; large eddy simulation; spray; plasmas; Gases; lagrangian particle tracking; jet in crossflow; fluiddynamik; plasma;

   Abstract : The objective of this thesis is to numerically simulate a fluid jet injected into a crossflow of the same or another fluid, respectively. Such flows are encountered in many engineering applications in which cooling or mixing plays an important role, e.g. gas turbine combustors. READ MORE

6. 4. A microfluidic toolbox to fabricate, sort and characterize thermoresponsive colloidal molecules and their assemblies

   Author : Feifei Peng; NanoLund: Centre for Nanoscience; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microgels; Thermoresponsive Colloidal Molecules; Microfluidics; Self-Assembly; Microgels; Thermoresponsive Colloidal Molecules; Microfluidics; Self-Assembly;

   Abstract : In this thesis we discuss the assembly of thermoresponsive microgel particles into small clusters, and their use as colloidal molecules with specific and directional interactions. The underlying goal is to use these particles as advanced building blocks for new types of self- assembled structures with novel or vastly improved properties, and as model particles for investigating fundamental problems in condensed matter physics.

7. 5. Phase Separation and Gelation of Biopolymers in Confined Geometries

   Author : Sophia Wassén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; gelation; gelatin–maltodextrin; whey protein isolate–gellan gum; structure evolution; confinement; biopolymer mixture; image analysis.; spinodal decomposition; phase separation; confocal laser scanning microscopy; microstructure;

   Abstract : Many biopolymer mixtures exhibit segregative phase separation that generates regions enriched in one polymer and depleted in the other. Today, much is known of how phase separating biopolymer systems behaves in bulk phase, and the final morphology can be controlled and tailored with high precision. READ MORE
