  1. 1. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

    University essay from KTH/Fiber- och polymerteknologi

    Author : Felix Bogdan; [2023]
    Keywords : Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

    Abstract : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. READ MORE

  3. 2. Emulsifying properties of cellulose oxalate and pectin from Norway spruce bark

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Semonti Hussain; [2022]
    Keywords : Cellulose oxalate COX ; Bark; Norway spruce; Pectin; Pickering emulsion; Pulp;

    Abstract : Nanocellulose is a sustainable material and has shown interesting properties in various applications. One such application is Pickering emulsion, where the nanocellulose stabilizes the oil and water interface. READ MORE

  4. 3. Unspecific interactions in different batch variations of agarose based base matrices at different NaCl concentrations.

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Kejvan Ghofranpanah; [2022]
    Keywords : Lysozyme; hydrophobicity; size exclusion chromatography; NaCl concentrations; isocratic elution; Lysozym; hydrofobicitet; size exclusion chromatography; NaCl-koncentrationer; isokratisk eluering;

    Abstract : Size exclusion chromatography (SEC) separates molecules based on their actual size rather than their molecular weight. This indicates that the smaller a molecule is, the longer it will be held in the column since it can penetrate the pores more effectively than a bigger molecule, resulting in a longer retention time, whereas the larger molecule has a shorter retention time.

  5. 4. Orbit-simulator for downstream processes

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Andreas Malmström; [2022]
    Keywords : Chemical engineering; Process simulation; Downstream processes; Orbit; Preparative chromatography; Python; Lumped Rate Models; Technology and Engineering;

    Abstract : In an ever more digitilized society, the transition is palpable also in the pharmaceutical industry. The control system Orbit was developed at the department of chemical engineering at Lund University, to be able to automate downstream processes based on the ÄKTA-system. READ MORE

  6. 5. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Linnea Georgii; [2021]
    Keywords : PFAS; modelling; competitive sorption; adsorption; isotherms; PFAS; modellering; konkurrenseffekter; adsorption; isotermer;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) have become contaminants of increasing concern to society due to the contamination of drinking water and the ecosystem. A better understanding of the sorption and transport of PFASs in soil systems is urgently needed, however there have been few studies dedicated to investigating competitive sorption among PFASs, and there is no available model to model such effects.
