  1. 1. 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.

  3. 2. Phenol-Protein Solution Stability

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Johan Sjölund; [2022]
    Keywords : Phenol; Protein; Proteins; Lysozyme; Betalactoglobulin; Trastuzumab; Lipase; GAZ; GA-Z; Palifermin; Titration; Probedrum; Pharmaceutical Technology; Chemistry;

    Abstract : Phenol is a commonly used preservative in pharmaceutical protein solutions. It is compatible with most proteins but can cause aggregation and denaturation at higher concentrations or in more sensitive proteins. READ MORE

  4. 3. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  5. 4. Detection of Contaminants in Water Using Surface Enhanced Raman Spectroscopy

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Freja Hansson; [2021]
    Keywords : Raman; Surface-enhanced Raman Spectroscopy; nanoparticles; contaminants; plasmonics;

    Abstract : Due to deteriorating water quality and the world’s increasing demand for clean water, the need for cheap, easy and portable techniques to characterize and quantify pollutants in waters is urgent. Hence, surface-enhanced Raman spectroscopy (SERS) have gained considerable attention in this field. READ MORE

  6. 5. Ion specific effects in polymer conformation

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Lovisa Svanholm; Anna Köttö; Samuel Deuda Lundkvist; [2021]
    Keywords : Poly N-isopropylacrylamid ; PNIPAM; pre-transitional chain collapse; ion specific effects; Hoffmeister series; LCST; diffusion NMR; self-diffusion NMR; fractionation; kosmotropes; chaotropes; inversion recovery experiment;

    Abstract : It is well known that ions affect polymers in specific ways not solely based on electric charge, usually referred to as the Hoffmeister effect or ion specific effects. Poly(N-isopropylacrylamid) (PNIPAM) is a thermosensitive polymer with a LCST at 32℃. READ MORE
