  1. 11. The effectivity of vacuum impregnation with glycerol and secondary metabolites on electroporated arugula leaves to improve freezing stability.

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Oscar de Kuijer; [2021]
    Keywords : Pulsed electric field PEF; Arugula; Electroporation; Secondary metabolites; Glycerol; Food engineering; Livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. READ MORE

  3. 12. 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

  4. 13. 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.

  5. 14. Cellulose nanocrystals functionalized cellulose acetate electrospun membranes for adsorption and separation of nanosized particles

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : José Ignacio Del Río De Vicente; [2021]
    Keywords : Electrospinning; Cellulose Nanocrystals; Filtration; Adsorption; Cellulose Acetate Fibers;

    Abstract : Filtration and separation technologies remain as one of the biggest challenges humanity currently faces. The separation of different elements such as bacteria, viruses, heavy metals, particles, and chemical agents require the development of multifunctional membranes. READ MORE

  6. 15. BICONTINUOUS MACROPOROUS MATERIALS FROM EPOXY RESIN-BASED MONOLITHS

    University essay from Umeå universitet/Kemiska institutionen

    Author : Thuy Trân Ho-Thi; [2021]
    Keywords : ;

    Abstract : In this project, hydrophilic bicontinuous microporous materials were synthesized via one‑pot polycondensation, using epoxy compounds and polyamines as the main monomer and curing agents. To achieve this goal, two approaches have been taken. READ MORE
