  1. 1. Greening peptide chemistry by using NBP as solvent for SPPS

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Andrea Ölander; [2022]
    Nyckelord :SPPS; Green chemistry; Peptide Synthesis; Organic chemistry; Organisk kemi; Chemistry;

    Sammanfattning : The preferred method for synthesising therapeutic peptides today is by Solid-Phase Peptide Synthesis (SPPS). SPPS is a wasteful process, where the main component of the waste is hazardous solvents, i.e., N,N-dimethylformamide (DMF), N-methylpyrrolidone (NMP) or dichloromethane (DCM). LÄS MER

  3. 2. Development of MALS methods for exosome size analysis

    Master-uppsats, KTH/Kemi

    Författare :Terese Andersson; [2022]
    Nyckelord :Exosomes; Multiangle light scattering; MALS; extracellular vesicles; Exosomer; Multiangle light scattering; MALS; extracellulara vesiklar;

    Sammanfattning : Exosomer är extracellulära vesiklar i nanostorlek som frigörs från cellerna till den extracellulära matrisen. Exosomer är laddade med nukleinsyror, proteiner, och lipider, och fungerar som kommunikatorer mellan celler. Det har gjort dem mycket attraktiva for forskning inom terapi, diagnostik och transport av läkemedel. LÄS MER

  4. 3. Acid retardation : recovery and recycling of acid and metal

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Cecilia Bood; [2020]
    Nyckelord :Acid retardation; Ion exchange; Pickling; Stainless steel;

    Sammanfattning : During the production of steel, an oxide scale is formed on the surface and to achieve anadequate quality of the surface the scale needs to be removed. Acid pickling is a surfacetreatment where the oxide scale is removed by acid. LÄS MER

  5. 4. Per- and Polyfluoroalkyl Substances (PFASs) Removal from Landfill Leachate : Efficiency Evaluation in Column Experiments

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emelie Johnson; [2019]
    Nyckelord :;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are known for their wide spread in the environment, their persistent properties and their ability of biomagnification through the food chain. With properties such as oil and water repellence, temperature resistance and a long lifespan they have been frequently used in various areas, e.g. LÄS MER

  7. 5. Bark assortments for tall oil production

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Forest Biomaterials and Technology (from 131204)

    Författare :Patrik Isacsson; [2016]
    Nyckelord :tall oil; bark; extractives; lipophilic compounds; CTO; TOFA; TOR; fatty acids; resin acids; rosin; Norway spruce; Scots pine; Picea abies; Pinus sylvestris;

    Sammanfattning : Fatty and resin acids in bark residues from forest industries can be used to produce high-value green chemicals. Of the assortments investigated, the bark of spruce pulpwood held the highest amount of these compounds with an average yield of 0.9 kg per cubic meter of wood. LÄS MER
