  2. 1. Processing of self-reinforced poly(ethylene terephthalate) composites for automotive applications

    Author : Lars Jerpdal; Malin Åkermo; Hans-Peter Heim; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The vehicles of the future must have less negative environmental impact during their use phase than the vehicles of today in order to avoid major climate change on earth. Consequently electric vehicles are currently under development with the purpose of reducing CO2 emissions when the vehicle isdriven. READ MORE

    Abstract : Since the beginning of the mass production in the 1940s, plastic has been manufactured in quickly increasing amounts. Plastic debris accumulates in the environment and lately much attention has been drawn to the pollution in the world’s oceans. READ MORE

  6. 4. Migration from plastic food packaging during microwave heating

    Author : Jonas Alin; Minna Hakkarainen; Sahar Al-Malaika; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; migration; food packaging; microwave; degradation; food simulant; antioxidant;

    Abstract : Microwave heating of food has increased rapidly as a food processing technique. This increases the concern that chemicals could migrate from food packaging to food. The specific effect of microwave heating in contrast to conventional heating on overall and specific migration from common plastic food storage boxes was studied in this work. READ MORE

  7. 5. Fundamentals of Wetting and Mechanical Durability of Superhydrophobic Coatings

    Author : Pontus Olin; Lars Wågberg; Fredrik Tiberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : In paper I the friction between three different superhydrophobic surfaces and water drops were investigated using high‑speed video. The surfaces were two based on a hydrophobic wax and the third was the leaf of a Lotus (Nelumbo Nucifera). The acceleration of water drops was measured as a function of drop size and surface inclination. READ MORE
