  4. 2. Improving alternatives assessment of plastic additives : exploring in silico tools to identify less hazardous flame retardants

    Author : Ziye Zheng; Patrik L. Andersson; Hans Peter Arp; Gregory Peters; Gerrit Schüürmann; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemical alternatives assessment; plastic additives; flame retardants; hazard; emission; in silico; modeling; quantitative structure-activity relationship QSAR ; multi-criteria decision analysis MCDA ; environmental science; miljövetenskap; organisk kemi; Organic Chemistry; ekotoxikologi; Ecotoxicology; Toxicology; toxikologi;

    Abstract : Alternatives assessment is applied for replacing hazardous chemicals with viable, safer substitutes. High quality experimental hazard data, however, are usually unavailable for this purpose, and obtaining in silico data is the only approach to fill in data gaps. READ MORE

  5. 3. Structure and mechanical properties of dual phase steels : An experimental and theoretical analysis

    Author : Ylva Granbom; John Ågren; Ir Bruno C. De Cooman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dual phase steels; continuous annealing; dilatometry; microstructure; mechanical properties; process parameters; dislocation model; plastic deformation; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik; Mikrostrukturutveckling i avancerade höghållfasta stål;

    Abstract : The key to the understanding of the mechanical behavior of dual phase (DP) steels is to a large extent to be found in the microstructure. The microstructure is in its turn a result of the chemical composition and the process parameters during its production. READ MORE

  6. 4. Analysis and modelling of plastic bending processes

    Author : Zheng Tan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : It is well known that anisotropic properties of material allect forming of sheet metals and that non-homogeneous deformation across thickness of a bend gives rise to residual stresses. The interaction between material and process parameters determines, in a very complex manner, the formability of material. READ MORE

  7. 5. Microstructures for Chemical Analysis : Design, Fabrication and Characterisation

    Author : Malin Svedberg; Fredrik Nikolajeff; Greger Thornell; Jan-Åke Schweitz; Sami Franssila; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; electrospray ionisation mass spectrometry; polymer microfabrication; paraffin actuators; hot embossing; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The interest for miniaturisation in chemical and biological analysis has increased in recent years. In this work, the design, fabrication and characterisation of tools for microanalysis have been studied. The focus is set on polymer microchips for applications in chemical analysis. READ MORE
