2. 1. Thermally Expandable Microspheres Prepared via Suspension Polymerization - Synthesis, Characterization, and Application

   Author : Magnus Jonsson; Eva Malmström Jonsson; Søren Hvilsted; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermally expandable microspheres; Polymer chemistry; Polymerkemi;

   Abstract : Thermally expandable microspheres are polymeric core/shell particles in which a volatile hydrocarbon is encapsulated by a thermoplastic shell. When these microspheres are heated, they expand and increase their volume dramatically. READ MORE

4. 2. Novel Microfluidic Devices Based on a Thermally Responsive PDMS Composite

   Author : Björn Samel; Göran Stemme; Jörg Kutter; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEMS; microsystem technology; micro total analysis system; lab-on-a-chip; microfluidics; composite actuator; expandable microspheres; PDMS; poly dimethylsiloxane; disposable; wafer bonding; adhesive bonding; PDMS bonding; adhesive PDMS bonding; selective PDMS bonding; microcontact printing; Electrical engineering; Elektroteknik;

   Abstract : The field of micro total analysis systems (μTAS) aims at developments toward miniaturized and fully integrated lab-on-a-chip systems for applications, such as drug screening, drug delivery, cellular assays, protein analysis, genomic analysis and handheld point-of-care diagnostics. Such systems offer to dramatically reduce liquid sample and reagent quantities, increase sensitivity as well as speed of analysis and facilitate portable systems via the integration of components such as pumps, valves, mixers, separation units, reactors and detectors.

5. 3. Shaping Macroporous Ceramics : templated synthesis, X-ray tomography and permeability

   Author : Linnéa Andersson; Lennart Bergström; Ludwig Gauckler; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alumina; ceramic; CO2 capture; colloidal processing; expandable microspheres; gel casting; layer-by-layer; macroporosity; near-net shape; non-destructive evaluation; permeability; porosity; sacrificial templating; X-ray computed tomography; Chemistry; Kemi; Materials Chemistry; materialkemi;

   Abstract : Macroporous ceramic materials have found widespread technological application ranging from particulate filters in diesel engines, tissue engineering scaffolds, and as support materials in carbon capture processes. This thesis demonstrates how the pore space of macroporous alumina can be manipulated, analysed in three-dimensions (3D) using visualisation techniques, and functionalised with a CO2-adsorbing material.

6. 4. Exploring bio-based and biodegradable polymers: free-radical polymerization, hydrolysis and applications

   Author : Maryam Mousa; Eva Malmström; Magnus Jonsson; Anna Larsson Kron; Seema Agarwal; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Bio-based polymers; biodegradation; branched polyesters; thermally expandable microspheres; copolymerization; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Abstract : Increasing concerns regarding the depletion of fossil-based resources and theaccumulation of plastic waste in the environment have resulted in extensiveresearch aimed at finding more sustainable alternatives to today’s plastics.In this work, bio-based and biodegradable polymers have been synthesizedusing free-radical polymerization in homogeneous and heterogeneoussystems.
