  1. 6. Quantification of Swelling in Sealing Materials

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Johanna Möller; Paula Erlandsson; [2021]
    Keywords : elastomer; rubber; gaskets; NBR; EPDM; swelling; diffusion coefficient; polymer technology; Technology and Engineering;

    Abstract : The objective of this study was to quantify swelling in gasket materials to better predict the gaskets life span in heat exchangers. Alfa Laval produces plate heat exchangers, which are a common unit within the process industry. There are different types of plate heat exchangers, and one type is sealed with gaskets. READ MORE

  3. 7. Composition and property study of adhesives based on poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

    University essay from KTH/Fiber- och polymerteknologi

    Author : Nathalie Johnsson; [2021]
    Keywords : Poly 3-hydroxybutyrate-co-3-hydroxyvalerate ; PHBV; Adhesive; Labels; Additives; Poly 3-hydroxybutyrate-co-3-hydroxyvalerate ; PHBV; Bindemedel; Etiketter; Additiv;

    Abstract : Lim klassificeras som ett ämne som kan hålla ihop två ytor så att de motstår separation. Dagens lim kan anpassas efter vilken applikation de ska användas till och kan ha ett stort antal olika egenskaper. De fysikaliska och kemiska egenskaperna av limmet är de viktigaste faktorerna för att bilda en bra limbindning. READ MORE

  4. 8. Quantification using SERS on a colloidal substrate

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Kasper Eliasson; [2021]
    Keywords : SERS; spectrometry; nano technology; plasmonics;

    Abstract : This thesis explores the practical usefulness of surface enhanced Raman spectroscopy on a colloidal substrate for quantification of organic analytes in a water matrix. The method evaluated is very simple and accessible as it utilizes a commercially available hand held Raman spectrometer and citrate reduced silver colloid substrate. READ MORE

  5. 9. Aroma components of long ripened cheese and their origin, variation and contribution to flavour : with focus on propionic acid

    University essay from SLU/Department of Molecular Sciences

    Author : Sandra Carlsson; [2021]
    Keywords : cheese ripening; aroma components; volatile compounds; metabolism of lactose; lactate and citrate; ; proteolysis; lipolysis; propionic acid bacteria; sensory evaluation;

    Abstract : Flavour compounds in cheese are formed by metabolism of residual lactose, lactate and citrate, proteolysis and lipolysis through the activity of e.g., starter bacteria. Generally identified aroma components in cheese are fatty acids, esters, alcohols, ketones, lactones, aldehydes, and sulphur compounds. READ MORE

  6. 10. Olika oorganiska kvävekällors effekt på blåbärsplantors tillväxt

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)
