  1. 1. Thiol-ene Nanostructuring

    Författare :Reza Zandi Shafagh; Klas Tommy Haraldsson; Wouter van der Wijngaart; Niels Bent Larsen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanostructuring; thiol-ene; OSTE; electron beam lithography EBL ; reaction injection molding RIM ; nanoimprint lithography NIL ; BioNEMS; QCM; digital bioassay; protein patterning; Lab-on-a-chip; polymer;

    Sammanfattning : Improving the health and well-being of humankind does not only constitutepart of our moral codes, but is also enlisted as the number three goal ofthe 2030 agenda for sustainable development set by the UN. Fulfilling suchobjective in the regions of resource-poor settings or for age groups with morevulnerability to infectious agents demands immediate actions. LÄS MER

    Sammanfattning : Within healthcare there is a market pull for biomedical devices that can rapidly perform laboratory processes, such as diagnostic testing, in a hand-held format. For this reason, biomedical devices must become smaller, more sophisticated, and easier to use for a reasonable cost. LÄS MER

  4. 3. A Novel Rearrangement of Allyl Benzyl Ethers and Aspects on the Glyoxylate Ene Reaction

    Författare :Johan Wennerberg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; liverwort; natural product synthesis; phenyl butyraldehydes; allyl benzyl ethers; 2-hydride migration; 1; 4-rearrangement; regio selectivity; shape selectivity; zeolite; Ene reaction; Taxol A-ring; naphthalene derivatives; dihydronaphthalenes; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis describes an improvement of the glyoxylate ene reaction by using siamyl glyoxaylate and a development of the novel rearrangement of allyl benzyl ethers. The glyoxylate ene reaction was used as a key reaction in a 8-step synthesis of a Taxol A-ring building block. LÄS MER

  5. 4. Intrinsically Proton-Conducting Benzimidazole Units Tethered to Different Polymer Chain Architectures

    Författare :Christian Persson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; biopolymers; Kemiteknik och kemisk teknologi; Polymer technology; Chemical technology and engineering; Materiallära; materialteknik; Material technology; Makromolekylär kemi; Macromolecular chemistry; proton-exchange membrane fuel cell; structure diffusion; thiol-ene reaction; segmental mobility; high temperature; benzimidazole; block copolymers; polymer electrolyte; anhydrous proton conductivity;

    Sammanfattning : Proton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for powering cars, laptops, buildings etc. LÄS MER

  7. 5. Dendrimers : Synthesis, Characterization and Use in Thiol-Ene Networks

    Författare :Camilla Nilsson; Eva Malmström; Andreas Heise; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymer; molecular physics; Polymer chemistry; Polymerkemi;

    Sammanfattning :  Dendrimers are perfectly branched, well-defined macromolecules with a layered structure and a large amount of peripheral end groups. The high functionality in combination with the possibility of dendrimers to adopt a globular shape at high molecular weights, gives them very unique properties. LÄS MER
