  1. 11. Synthesis and Photochemical Characterisation of Photoactive Compounds for Molecular Electronics

    Författare :Behabitu Ergette Tebikachew; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoswitch; norbornadiene; photocleavable protection; Molecular electronics;

    Sammanfattning : In this modern age of technology, communication is highly reliant on computing devices such as mobile phones and computers. The advent of artificial intelligence (AI) and internet of things (IoT) as well as the widespread use of user-generated contents (UGC) are demanding more computing power and large data storage.

  2. 12. Synthesis and Photophysical Characterization of Annihilator-Sensitizer Pairs for Triplet-Triplet Annihilation Based Photon Upconversion

    Författare :Victor Gray; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Triplet-Triplet Annihilation; Photon Upconversion; Anthracene;

    Sammanfattning : Transitioning to a future society, independent of fossil fuels, will denitely require the use of solar radiation for power and fuel production. Due to energy mismatch betweendevice absorption and the broad band irradiation provided by the sun there are severe limitations to how efficient devices for direct conversion of solar radiation can be.

  3. 13. Synthesis and spectroscopic characterization of emerging synthetic cannabinoids and cathinones

    Författare :Andreas Carlsson; Johan Dahlén; Martin Josefsson; Peter Konradsson; Simon Dunne; Mikael Hedeland; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The application of different analytical techniques is fundamental in forensic drug analysis. In the wake of the occurrence of large numbers of new psychoactive substances possessing similar chemical structures as already known ones, focus has been placed on applied criteria for their univocal identification.

  4. 14. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications

    Författare :Jonas Mindemark; Tim Bowden; Andrew Dove; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA condensation; gene delivery; ionomers; polyplexes; self-assembly; amphiphiles; biodegradable; biological applications of polymers; transfection; cyclic carbonate monomers; polycarbonates; semicrystalline polymers; click chemistry; triazoles; cycloaddition; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. LÄS MER

  5. 15. Conjugation in Organic Group 14 Element Compounds : Design, Synthesis and Experimental Evaluation
