  1. 1. Microbial production of chemical building blocks from lignin

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Kevin Bertilsson; [2024]
    Keywords : Lignin; Green plastic; Vanillin; Microbial production; Applied microbiology; Biology and Life Sciences;

    Abstract : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. READ MORE

  3. 2. Molecular Characterization of High β-Glucan Lines in Oats

    University essay from Lunds universitet/Tillämpad biokemi

    Author : Abhinav Majumdar; [2022]
    Keywords : Applied biochemistry; Oats; β-Glucan; Dietary fibres; Arbinoxylan; Biology and Life Sciences;

    Abstract : Oats (Avena sativa) are part of the cereal whole grain family, and their production is on the rise for the past few years due to extensive research done on the health benefits it can provide to humans. ScanOats project in Sweden is one of the research groups across the world that has done extensive work on oats. READ MORE

  4. 3. Determination of the inelastic mean freepath for SiO2 and the BBL polymer : A study with XPS and HAXPES

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Rickard Gauffin; [2022]
    Keywords : XPS; HAXPES; IMFP; Polymer;

    Abstract : This study targets methodology development using Photoelectron Spectroscopy (PES) as a tool for investigating material surfaces. When analysing samples with X-ray Photoelectron Spectroscopy (XPS) and Hard X-ray Photoelectron Spectroscopy (HAXPES), it is important to know the probing depth of the samples. READ MORE

  5. 4. Reactivity and photochemistry of copper halide complexes

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

    Author : Needa Athitaya Wicksell Chuainukun; [2021]
    Keywords : Photochemistry; Copper iodide complexes; Substituted pyridines; Thin films; Luminescence lifetime;

    Abstract : This paper deals with 3-picoline, 4-picoline, 3,4-lutidine and 3,5-lutidine complexes of copper(I) iodide (CuI(3-pic), CuI(4-pic), CuI(3,4-lut) and (CuI(3,5-lut)). The experimental investigation was divided into several parts. Firstly, the synthesis and characterization of the compounds both as powder and as thin films. READ MORE

  6. 5. Biomimetically improved materials comprising microfibrillated cellulose

    University essay from Umeå universitet/Kemiska institutionen

    Author : Cornelia Byström; [2021]
    Keywords : ;

    Abstract : Microfibrillated cellulose (MFC) is a renewable, cellulosic material mainly producedfrom wood fibers, which are found in the secondary cell walls of plant cells. With theincreased demand for renewable biopolymer films in packaging, MFC has emerged asa potential alternative to non-renewable polymer films. READ MORE
