1. 1. Chemical modification of starch in order to get thermoplastic properties

   University essay from KTH/Materialvetenskap

   Author : Emma Hallbert; Elsa Wadman; [2023]
   Keywords : thermoplastic starch; dialdehyde starch; schiff-base; imine chemistry; termoplastisk stärkelse; dialdehydstärkelse; schiffbas; iminkemi;

   Abstract : There are numerous advantages of replacing traditional non-biodegradable synthetic plastics with bio-based plastics. Starch is globally available, cheap, renewable, and biodegradable. However, starch has a poor product performance and is relatively difficult to process, as conventional melt processing techniques cannot be used. READ MORE

3. 2. Bio-based resins for digital light processing : Mechanical and degradable properties

   University essay from KTH/Materialvetenskap

   Author : Moa Eklund; Amanda Olofsson Ribrant; [2023]
   Keywords : Digital Light Processing 3D Printing DLP ; Additive manufacturing; Bio-based; Polymer; Thermosets; Covalent Adaptable Networks CANs ; Recycling; Characterization.; Digital Light Processing 3D Printing DLP ; Additiv tillverkning; Bio-baserad; Polymer; Härdplast; Kovalenta Anpassningsbara Nätverk CANs ; Återvinning; Karaktärisering.;

   Abstract : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

4. 3. Biobased Photocurable Resins for 3D-Printing of Self-Healable & Recyclable Thermosets

   University essay from KTH/Fiber- och polymerteknologi

   Author : Anna Gardell; Maria Aspenberg; Julia Aziz; [2022]
   Keywords : vanillin; vitrimer; imine; resin; dynamic covalent bonds; biobased thermoset; photocuring; chemical recyclability; self-healing; digital light processing DLP ; 3D-printing; vanillin; vitrimer; imin; resin; dynamiska kovalenta bindningar; biobaserad härdplast; fotohärdning; kemisk återvinningsbarhet; självläkning; digital light processing DLP ; 3D-utskrift;

   Abstract : Överkonsumtionen av engångsartiklar i fossilbaserad plast är ett av dagens stora miljöproblem. Således finns en efterfrågan på strategier för framställning av biobaserade plaster i allmänhet och härdplaster i synnerhet. READ MORE

5. 4. Synthesis and characterization of half-sandwich complexes with salicylaldimine ligand derivatives

   University essay from Lunds universitet/Kemiska institutionen

   Author : Ujala Mahmud; [2021]
   Keywords : Malaria; Plasmodium; Ruthenium; Iridium; Rhodium; Inorganic chemistry; Chemistry;

   Abstract : New half-sandwich complexes of pentamethylcyclopentadienyl-rhodium, iridium, and p-cymene-ruthenium have been synthesized and characterized. All metal complexes contain ligands based on a 4-chloroquinoline framework analogous to the antimalarial drug chloroquine. READ MORE

6. 5. Algae hydrocarbons designed for bio-based lubricants

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

   Author : Elin Sjöhag; [2020]
   Keywords : Microalgae; macroalgae; lubricant; alginate; grease; Mikroalger; makroalger; smörjmedel; alginat; förtjockningsmedel;

   Abstract : Smörjmedel är en nödvändighet för maskiner för att minska slitage och energiförbrukning. Dock är över 95% av de använda smörjmedlen i dag fossilbaserade. Smörjmedel baserade på vegetabiliska oljor finns tillgängliga men har ofta en lägre oxidativ stabilitet och sämre lågtemperaturegenskaper än deras fossilbaserade motsvarigheter. READ MORE
