  1. 1. Insamling av skogliga data med applikationen Arboreal Skog : en studie om mätprecision, noggrannhet och effektivitet

    University essay from SLU/Department of Forest Biomaterials and Technology (from 131204)

    Author : Lisa Lindberg; [2020]
    Keywords : skogsinventering; förstärkt verklighet; skogsteknologi; mätfel; skogsuppskattning;

    Abstract : Skogsinventering kräver en del utrustning i fält där klave, höjdmätare och måttband är vanligt förekommande instrument. Med applikationen Arboreal skog kan skogs- uppskattning istället ske med mobiltelefonen som verktyg vid provyteinventering. READ MORE

  3. 2. Probing ion movement in conjugated polymers

    University essay from Uppsala universitet/Strukturkemi

    Author : Markus Hall; [2019]
    Keywords : Light-emitting electrochemical cell; conjugated polymer; electrochemical doping; MEH-PPV; lithium; trifluoromethanesulfonate; trimethylolpropane ethoxylate;

    Abstract : Electronic conduction in conjugated polymers can be increased through electrochemical doping. This is utilised in light-emitting electrochemical cells and allows for a less demanding manufacturing process compared to the related organic light-emitting diode. READ MORE

  4. 3. Model Calibration and Optimization of a Protein Purification Process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sadiq Al-Kaisy; [2015]
    Keywords : Model calibration; Protein purification; Ion-exchange chromatography; Optimization; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

    Abstract : Four different chromatography models were calibrated to describe the separation of a ternary protein mixture consisting of lysozyme, cytochrome C and ribonuclease A in an ion-exchange chromatography column. The models are based on the same column model, the kinetic dispersive model. READ MORE

  5. 4. Ion association to poly(N-isopropylacrylamide) by diffusion and electrophoretic NMR

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Cedrik Wiberg von Schantz; [2013]
    Keywords : PNIPAM; poly N-isopropylacrylamide ; electrophoretic NMR; diffusion NMR; LCST; ion association;

    Abstract : PNIPAM (poly(N-Isopropylacrylamide)) is a well-known thermoresponsive polymer. Dissolved in water, it shows a structural change at 32 oC, above which the polymer folds together, and a phase separation occurs. READ MORE

  6. 5. How ionic are ionic liquids?

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Kristoffer Bernhem; [2011]
    Keywords : Ionic liquid; ion charge; association; electrophoretic NMR; diffusion NMR.;

    Abstract : Ionic liquids are continuously finding more and more applications, both in research and in the industry. Many attempts have been made to find parameters that could be used to describe all ionic liquid systems. Five years ago a Japanese group applied the work of Gutmann on ionic liquids to use ionic association to describe solvation effects. READ MORE
