1. 11. Infrared Curing of Glass Fiber Composite Tube : Optimization of the curing cycle

   Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

   Författare :Rasmus Fredheim; [2021]
   Nyckelord :;

   Sammanfattning : This thesis has investigated the possibility of optimizing curing time by changing the energy source from a conventional oven to infrared radiation (IR) and if it is possible to achieve similar results as the company's current production of glass fiber composite tubes.   Many different parameters (time, temperature, heating rate, and rotation speed) might influence a cured composite tube's properties.

3. 12. The discoloration of polyethylene obtained from chemical separation of laminates: Investigating additives and other potential causes

   Master-uppsats, Lunds universitet/Förpackningslogistik

   Författare :Can Feng; [2021]
   Nyckelord :Delamination; multilayered packaging; polymer discoloration; plastic film; recycling; Technology and Engineering;

   Sammanfattning : PolyAl, the material composed of laminated polyethylene (PE) films and aluminum (Al) in carton, is a challenge in recycling due to the strong adhesion of the layers and the low value of the end products. In Europe, recent efforts to improve the circularity of carton packages include the chemical separation of PolyAl, in order to obtain higher values of the PE and Al separately. LÄS MER

4. 13. Surface functionalization of nonwoven polypropylene with BTCA polycarboxylic acid in supercritical carbon dioxide medium

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Md Fahad Khan; [2021]
   Nyckelord :Nonwoven polypropylene; Supercritical carbon dioxide; Surface functionalization; 1; 2; 3; 4- Butanetetracarboxylic acid; Impregnation; Environmentfriendly; Hydrophilicity;

   Sammanfattning : Nonwoven polypropylene has been utilized broadly in various hygienic and medical textile applications because of its excellent mechanical properties, chemical resistance, and minimal expense contrast with other synthetic polymers. However, the insufficiency of surface tethering groups, including adhesion, wettability, and hydrophilicity, some applications are not convenient on nonwoven polypropylene surfaces such as dyeing, printing, attachment of antibacterial and bioactive agents.

5. 14. Energy poverty and the elderly-care: Exploring energy poverty in the elderly-care through case studies with social welfare organizations in Taiwan

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Tzu Ling Kuo; [2020]
   Nyckelord :Science General;

   Sammanfattning : The topic of energy poverty has recently gained prominence amongst researchers and academia in Taiwan within the context of rising energy prices and low emission energy transitions. Social welfare organizations (SWOs) that provide 24-hour residence and care for vulnerable populations, such as the elderly and disabled, highly depend on various energy services and are likely to be significantly affected due to rising energy prices, adding to their existing financial pressure.

7. 15. Novel workflow for metagenomics and transcriptomics analysis of A.D. systems

   Master-uppsats, SLU/Dept. of Animal Environment and Health

   Författare :Renaud Van Damme; [2020]
   Nyckelord :Metagenomics; transcriptomics; pipeline; A.D systems; Biogas; Bioinformatics;

   Sammanfattning : The A.D. systems (anaerobic digestion), when used in biogas reactors, are an advanced ecological way to produce energy while treating waste. The majority of the microbial community of the reactor remains unknown to this day, due to the impossibility to culture most of the bacteria individually. LÄS MER
