  1. 1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

    University essay from KTH/Fiber- och polymerteknologi

    Author : Anna Wessén; [2023]
    Keywords : Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

    Abstract : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

  3. 2. Molecular Insights into the Interactions of Monovalent Cations with Highly charged Fatty Acid Monolayers

    University essay from KTH/Kemi

    Author : Ran Carlhamn Rasmussen; [2023]
    Keywords : VSFS; Langmuir monolayer; ion specific effects; modified Poisson Boltzmann; carboxylic acid; VSFS; Langmuir monolager; jonspecifika effekter; modifierad Poisson Boltzmann; karboxylsyra;

    Abstract : Vibrational sum frequency spectroscopy har använts för att studera interaktionerna mellan monovalenta joner och laddade fettsyramonolager. Subfasen bestod av utvalda alkalihydroxidsaltlösningar med pH12, med huvudfokus på cesiumjonen. READ MORE

  4. 3. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Arvid Sandberg; [2023]
    Keywords : Dual ion batteries; materials science; chemistry; organic polymer;

    Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

  5. 4. Pre-Existing Film Music Re:sourced : Technical Aspects and Narratological Implications of Audible Diegetic Transitions in Joker and Other Films

    University essay from Uppsala universitet/Institutionen för musikvetenskap

    Author : Martin Danstål Skiöld; [2023]
    Keywords : film music; technical aspects; narratological implications; audible diegetic transitions; transaural displacements; diegetic; non-diegetic; intra-diegetic; meta-diegetic; supra-diegetic; trans-diegetic; sound advance; bridge; lag; story; discourse; instant; gradual; emotive; grounding; narrow; wide; Joker; Baby Driver; Coda; Guardians of the Galaxy; Star Wars;

    Abstract : This thesis concerns itself with a phenomenon found in film music that can be described as audible diegetic transitions. In short, an audible diegetic transition occurs when film music shifts from one implied musical placement to another by changing its pre­sented sound quality. READ MORE

  6. 5. The Ext-Algebra of Standard Modules of Bound Twisted Double Incidence Algebras

    University essay from Uppsala universitet/Algebra, logik och representationsteori

    Author : Mika Norlén Jäderberg; [2023]
    Keywords : Algebras; Finite-dimensional; Partially ordered sets; Modules; Quasi-hereditary; Ext-algebra; Schur algebra; Quiver; Path algebra; Categories; Morita equivalence; Yoneda product; Standard module; Homological algebra; Cohomology; Anick Chains;

    Abstract : Quasi-hereditary algebras are an important class of algebras with many appli-cations in representation theory, most notably the representation theory of semi-simple complex Lie-algebras. Such algebras sometimes admit an exact Borel sub-algebra, that is a subalgebra satisfying similar formal properties to the Borel sub-algebras from Lie theory. READ MORE
