1. 1. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

   Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Karin Hindborg; [2023-08-28]
   Nyckelord :colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

   Sammanfattning : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.

3. 2. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

   Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

   Författare :Karnsinee Viriyayudhakorn; [2023]
   Nyckelord :human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

   Sammanfattning : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. LÄS MER

4. 3. Investigation of acidic chemical recycling of poly(acetal-ester)s

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

   Författare :Saga Vesterbacka; [2023]
   Nyckelord :Poly actetal-ester s; Chemical plastic recycling; Hydrolysis; Acidic degradation; Akestra; PHVT; Re-polymerization; Polymer technology; Chemistry;

   Sammanfattning : Plastic recycling is a very relevant topic from both environmental and economic viewpoints. Chemical plastic recycling is a logical solution to the plastic problems, which shows the potential to reduce plastic waste and carbon emissions from burning the plastics. LÄS MER

5. 4. Investigating Yttrium Ruthenate Pyrochlore as an Anodic Electrocatalyst in Proton Exchange Membrane Water Electrolysis

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Kneev Sharma; [2023]
   Nyckelord :;

   Sammanfattning : As the energy transition progresses, the demand for green storage solutions is ever-increasing. Hydrogen storage is receiving increased interest and support due to its promising sustainability and flexibility. Proton-exchange, or polymer electrolyte, membrane (PEM) electrolyzers are a key technology supporting hydrogen storage systems. LÄS MER

7. 5. Solid-state fermentation of the microalgae Scenedesmus sp. for improved conservation and protein digestibility
