  1. 36. Surface Roughening of PET Meltspun Filament through Minor Phase Removal of Blend

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Farzad Zanganeh; [2018]
    Keywords : Roughening; Phase induced morphology; PET PS blend; Hydrophobicity; Drawing; Annealing;

    Abstract : Superhydrophobic fabrics have gained a huge interest in the industries recently. New legislation pushes the industries to eliminate the use of fluorinated materials in the production of these type of fabrics. READ MORE

  3. 37. A comparison between the effects of polylactic acid and polystyrene microplastics on Daphnia magna

    University essay from Stockholms universitet/Institutionen för miljövetenskap och analytisk kemi

    Author : Mikaela Puranen Vasilakis; [2017]
    Keywords : Microplastics; daphnia magna; bioplastics; feeding rate; reproduction; Mikroplast; daphnia magna; bioplast; födoupptag; reproduktion;

    Abstract : The effects of microplastics on zooplankton are an increasing environmental concern. Both primary microplastics that are produced as constituents of cosmetic products, as well as secondary microplastics that are formed by degradation of larger plastic debris, are ubiquitous in aquatic environments.

  4. 38. Combination of nanoparticles from polystyrene and the hormone 17alpha-ethinylestradiol (EE2) in water.

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Emma Nilsson; [2017]
    Keywords : water; nanoparticles; hormons; Plastic; Earth and Environmental Sciences;

    Abstract : Plastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. READ MORE

  5. 39. High Contrast Imaging Through Scattering Media Using Structured Illumination Fourier Filtering

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : David Frantz; [2017]
    Keywords : scattering media; Structured Illumination; optical Fourier filtering; Modulation Transfer Function; Monte Carlo simulation; Technology and Engineering;

    Abstract : In imaging, obtaining high contrast is of great importance. When imaging through scattering media, optical filtering techniques are used to filter out multiple light scattering which causes loss of contrast. READ MORE

  6. 40. Patterned Nanocomposite of Carbon Nanotube/Polymer

    University essay from Umeå universitet/Institutionen för fysik

    Author : Saeed Motaragheb Jafarpour; [2017]
    Keywords : ;

    Abstract : Single walled carbon nanotubes (SWCNTs) are carbon based nanostructures with extraordinary electronical and mechanical properties. They are used in a wide range of applications, usually embedded in polymer as fillers to form polymer based nanocomposites, in order to affect the electronic behavior of the polymer matrix. READ MORE
