  2. 1. Multifunctional Dendritic Scaffolds: Synthesis, Characterization and Potential applications

    Author : Yvonne Hed; Michael Malkoch; Mats Andersson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; AB2C monomer; Click chemistry; CuAAC; thiol-ene coupling chemistry; TEC; linear dendritic hybrids; micelle; hydrogel; bone adhesive;

    Abstract : The development of materials for advanced applications requires innovative macromolecules with well-defined structures and the inherent ability to be tailored in a straightforward manner. Dendrimers, being a subgroup of the dendritic polymer family, possess properties which fulfill such demands. READ MORE

  4. 2. Service life estimations in the design of a PCM based night cooling system

    Author : Göran Hed; Christer Sjöström; Andrew James Miller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building manufacturing engineering; Byggproduktionsteknik; Building engineering;

    Abstract : The use of Phase Change Material, PCM, to change the thermal inertia of lightweight buildings is investigated in the CRAFT project C-TIDE. It is a joint project with Italian and Swedish partners, representing both industry and research. PCMs are materials where the phase change enthalpy can be used for thermal storage. READ MORE

  5. 3. Approximation and Subextension of Negative Plurisubharmonic Functions

    Author : Lisa Hed; Urban Cegrell; Frank Wikström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex Monge-Ampère operator; Approximation; Plurisubharmonic function; Subextension; MATHEMATICS; MATEMATIK;

    Abstract : In this thesis we study approximation of negative plurisubharmonic functions by functions defined on strictly larger domains. We show that, under certain conditions, every function u that is defined on a bounded hyperconvex domain Ω in Cn and has essentially boundary values zero and bounded Monge-Ampère mass, can be approximated by an increasing sequence of functions {uj} that are defined on strictly larger domains, has boundary values zero and bounded Monge-Ampère mass.

  6. 4. The plurisubharmonic Mergelyan property

    Author : Lisa Hed; Urban Cegrell; Anders Fällström; Per Åhag; Jan Wiegerinck; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex Monge-Ampère operator; approximation; plurisubharmonic function; subextension; Mergelyan property; plurisubharmonic function on compact sets; Jensen measures; Mathematics; matematik;

    Abstract : In this thesis, we study two different kinds of approximation of plurisubharmonic functions. The first one is a Mergelyan type approximation for plurisubharmonic functions. READ MORE

  7. 5. Advanced polymeric scaffolds for functional materials in biomedical applications

    Author : Kim Öberg Hed; Michael Malkoch; Eric Drockenmuller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; hydrogel; PEG; dendritic monolayers; thiol-ene networks; off-stochiometric;

    Abstract : Advancements in the biomedical field are driven by the design of novel materials with controlled physical and bio-interactive properties. To develop such materials, researchers rely on the use of highly efficient reactions for the assembly of advanced polymeric scaffolds that meet the demands of a functional biomaterial. READ MORE
