  1. 11. Utveckling av koncept för ny åkprofil till bakgavellyft : Produktutveckling och konstruktion

    Kandidat-uppsats, Mittuniversitetet/Institutionen för kvalitets- och maskinteknik

    Författare :Gustav Fritzon; [2022]
    Nyckelord :linear motion; dimensioning; industrial production; FE analysis; linjär rörelse; dimensionering; industriell produktion; FE-analys;

    Sammanfattning : Detta examensarbete har utförts i samarbete med Z-lyften Produktion AB som tillverkar bakgavellyftar till lastbilar. En av deras modeller har funktionen att den kan köras in under lastbilen eller trailern. Lyften rullar då på hjul i så kallad slädprofiler som i sin tur är fästa mot lastbilen med ramfästen. LÄS MER

  2. 12. Mapping of Material & Conversion Parameters of Packaging Production – Boardio®

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Yusuf Qasem; Younes Chraibi Ottosson; [2022]
    Nyckelord :Chemical Engineering; Packaging; Packaging Production; Paperboard; Converting; Lamination; Extrusion; Die-cutting; X-ray tomography; GPI; Creasing; Perforation; Tensile Strength; Technology and Engineering;

    Sammanfattning : With an increased demand for sustainable packaging solutions for the ever-growing FMCG market, fiber-based systems rise as an answer to phasing out plastics in packages and reducing the humanity’s climate footprint. However, constructing a packaging solution largely consisting of paperboard comes with its challenges, such as integrating functionalities in the anisotropic paperboard that formerly were provided by a fundamentally different materials with divergent mechanical properties, being isotropic polymers.

  3. 13. Polymerization of isatin towards polymers for anion exchange membranes and gas separation applications

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Simone Facchini; [2022]
    Nyckelord :organic chemistry; membranes; isatin; polymers; Chemistry;

    Sammanfattning : In a world where the problem of energy resources, pollution and all aspects related to these issues becomes more and more dominant, a greater commitment is needed in the search for solutions. The goal of this project is to make a contribution to the research and development of new materials to reduce the environmental impact in some fields. LÄS MER

  4. 14. Sorption of novel side-chain fluorinated polymers to sediment - the impact of pH

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Hanna Erléus; [2022]
    Nyckelord :Scotchgard™; sorption; sediment; pH; side-chain fluorinated polymer surfactants; Lake Hjälmaren.;

    Sammanfattning : Fluorinated compounds are produced on a large scale and their releases are contaminating the environment. Among these are side-chain fluorinated polymers found in technical mixtures of Scotchgard™, which are used as surfactants in fabric coating. LÄS MER

  5. 15. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

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

    Författare :Alejandra Fernandez Castaneda; [2022]
    Nyckelord :Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).
