  1. 1. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Gustav Larsson; [2023]
    Nyckelord :organic solar cells; polymer; morphology; film; AFM;

    Sammanfattning : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.

  3. 2. Rostning av åkerbönor : en kostnadsanalys om lönsamheten för utfodring av rostade åkerbönor till ekologiska mjölkkor

    Kandidat-uppsats, SLU/Dept. of People and Society

    Författare :Hugo Eke-Göransson; John Engdahl; [2023]
    Nyckelord :Rostning av åkerbönor; bönrostning; ekologiska mjölkkor; kostnadsanalys; fodervärde; proteinkvalité; ekonomisk hållbarhet;

    Sammanfattning : I Sverige använder i dagsläget många ekologiska mjölkproducenter sig av soja som huvudprotein i fodret till sina djur. Soja odlas inte i någon större utsträckning i Sverige, det importeras från andra länder. LÄS MER

  4. 3. Investigation of new hot melt adhesives with plasticisers based on renewable resources : Investigating the use of sustainable plasticisers in hot melt adhesives

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Shadi Feyzabi; [2023]
    Nyckelord :Hot melt adhesives; renewable; mineral oil; vegetable oil; rheology; viscosity; loop tack; adhesive strength; Smältlim; förnybar; mineralolja; vegetabilisk olja; reologi; viskositet; loop tack; vidhäftningsstyrka;

    Sammanfattning : Hot melt adhesives (HMA) are a class of adhesives that, unlike solvent-or waterborne counterparts, do not contain organic solvents or other carriers, and are produced and subsequently applied in a molten state. The main components of HMA are polymers, tackifying resins, and a plasticiser. LÄS MER

  5. 4. Characterisation of Poly(trimethylene carbonate) and f-BTI2g-TVTCN blends for the use in Biosensors

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Sara El Ghamri; Ed Kammeby; Herman Göransson; Arvid Stjerngren; [2023]
    Nyckelord :Bionedbrytbara biosensorer; Biodegradable biosenors; Organic mixed ionic–electronic conductors; Carboxyl esterase; organic electrochemical transistors; poly trimethylene carbonate ;

    Sammanfattning : This report aims to study the degradation of poly(trimethylene carbonate) (PTMC) caused by the enzyme carboxylesterase in vitro. As well as to characterise polymer blends of f-BTI2g-TVTCN and poly(3-hydroxybutyric acid) as core components for organic electrochemical transistors (OETCs). LÄS MER

  7. 5. Investigating organic fertilisers’ ability to mineralize during the first month of plant propagation

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Sebastan Farkas; [2023]
    Nyckelord :organic fertilizers; sustainability; mineralisation; nitrification;

    Sammanfattning : There are many forms of organc fertilizers produced and sold in the EU, and it can be difficult to assess which ones are the best in regards of nutrient content and the rate of mineraliztion. Two separate trials were conducted to assess the mineralization rates of three different organic fertilizers, available for private customers, on the Swedish market. LÄS MER
