  3. 2. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    University essay from Karlstads universitet

    Author : Shiniar Said Saleh; [2023]
    Keywords : green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Abstract : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

  4. 3. Fullkornsintag bland barn och unga : analys av data från Livsmedelsverkets matundersökning

    University essay from SLU/Department of Molecular Sciences

    Author : Amina Laallam; [2021]
    Keywords : alkylresorcinoler; fullkorn; biomarkörer; matundersökningar; Livsmedelsverket;

    Abstract : Det finns många studier som visar ett samband mellan låg frekvens av insjuknande i metabola sjukdomar och ett högt fullkornsintag. Hälsoeffekter relaterade till fullkorn beror på dess rika innehåll på vitaminer, mineraler och kostfibrer Hälsoeffekter kan kartläggas och studeras på befolkningens matvanor och livsstil genom nationella studier och matundersökningar.

  5. 4. Preliminary Investigation into Quantitation of Pharmaceuticals in Lake Victoria Sediments : Development of a Method for Analysis of 11 Pharmaceuticals

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Robert Lundberg; [2021]
    Keywords : Lake Victoria; pharmaceutical; sediment; core; ASE; SPE; derivatization; GC-MS MS; GC-MS; 210Pb;

    Abstract : Although Lake Victoria is threatened by pollution there is a lack of knowledge about pharmaceuticals contaminants drained into the lake from large cities bordering the lake. Hence, the purpose of this project was to develop, validate and apply a method for analysis of pharmaceutical compounds accumulating in the Lake Victoria sediments. READ MORE

  6. 5. Implementation of a straightforward derivatizationmethod for the simultaneous analysis of short chainfatty acids and tricarboxylic acid cycle metabolitesby LC-qToF-MS.

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Renée Levisson; [2021]
    Keywords : Short-chain fatty acids; tricarboxylic acid TCA cycle; chemical derivatization; 3-nitrophenylhydrazine;

    Abstract : Short-chain fatty acids (SCFAs) and the tricarboxylic acid (TCA) cycle metabolites aresmall hydrophilic compounds that play crucial roles in biological species ranging fromenergy metabolism, immune homeostasis to cellular signalling. There is a need for reliableand precise quantification of these metabolites in biological matrices as they can providecrucial information of metabolic status and potentially be used as diagnostic biomarkersfor different pathological and physiological conditions.
