  1. 26. Methods for Evaluating Dewatering Properties of Sewage Sludge

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Nadia Abdalla; [2019]
    Keywords : sludge dewatering; sewage sludge; laboratory scale sludge treatment; dewatering sludge; dewatering sewage sludge; CST; capillary suction time test; centrifuge; lab-centrifuge; rheology; polymers conditioning; sludge conditioning; centrifuge on lab scale; evaluation of lab experiments; CST evaluation; mechanical de-watering evaluation; sludge dewatering at lab; lab scale dewatering process; sludge dewatering methods at lab; Chemical engineering; Lab centrifuge; Capillary Suction Time CST ; Mechanical sludge dewatering evaluation; Polymers conditioning of sludge; sewage sludge dewatering; methods for sludge dewatering at lab; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Abstract : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. READ MORE

  3. 27. Adsorption of lysozyme on Silica Surfaces and Specific ion effects

    University essay from Lunds universitet/Kemiska institutionen

    Author : Guillem Onyos de Plandolit Ruiz; [2019]
    Keywords : Ellipsometry; mesoporous silica nanoparticles; surfaces; physical chemistry; fysikalisk kemi; Chemistry;

    Abstract : Biomedical application of nanoparticles is largely associated to their fate in biological media which, in fact, is related to their surface properties. Surface functionalitzation plays a key role in determining biodegradation, cytotoxicity and biodistribution through interactions which may be meditated by the macromolecules occurring in biological media.

  4. 28. Silk's sweet spot: untangling the requirements for artificial silk extrusion using a biomimetic approach

    University essay from Lunds universitet/Tillämpad biokemi

    Author : Rodrigo Sanches Pires; [2019]
    Keywords : silk fibroin; injectability; extrusion; hydrogels; soft matter mechanics; biomimetic progressive acidification; silk self-assembly; thioflavin t; physical chemistry; biofabrication; spectroscopy; silk spinning; applied biochemistry; tillämpad biokemi; Technology and Engineering;

    Abstract : Up to this date, only a few silk hydrogels were reported to be injectable. Of these, none are truly biomimetic, and are instead comprised of blends with limited amounts of silk. Hence, no truly silk-based hydrogels exist as of today. READ MORE

  5. 29. Utformning av en standardiserad och utbytbar batterimodul till arbetsmaskiner

    University essay from SLU/Dept. of Energy and Technology

    Author : Martin Ericson; [2019]
    Keywords : elektrifiering av arbetsmaskiner; litiumbatteriets komponenter och system; modulsystem; framtidens lantbruk; skogsbruk och entreprenad;

    Abstract : The purpose of this master thesis was to clarify how a standardized and replaceable battery module for working machines can be constructed together with the necessary components and systems. For example were battery technology, cell format, charge and discharge intervals, working temperature, the need of cooling etc. investigated. READ MORE

  6. 30. Simulating Quantum Cascade Lasers with the Position and Energy Resolving Lindblad approach

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Maitane Muñoz Basagoiti; [2019]
    Keywords : quantum cascade lasers; quantum transport; simulations; electron transport; Physics and Astronomy;

    Abstract : Over the past two decades, Quantum Cascade Lasers (QCLs) have become an increasingly popular source for mid-infrared and terahertz radiation. Nowadays, their experimental development progresses fast with the aid of computer simulations. These reproduce carrier dynamics in the gain medium of the laser based on different transport models.
