  2. 1. Towards Abatement of Selected Emissions from Metals Manufacturing

    Author : Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; Teknisk materialvetenskap;

    Abstract : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. READ MORE

  5. 3. The influence of Morphology on the Transport and Mechanical Properties of Polyethylene

    Author : Bereket Neway; KTH; []
    Keywords : n-hexane diffusion; polyethylene; free volume; solubility; sorption; desorption; mechanical properties; orientation; thermal properties; blend;

    Abstract : The sorption/desorption behaviour of n-hexane in high molarmass linear polyethylene (PE) and branched PEs with 0.39 and5.09 hexyl branches per 100 main chain C atoms andcrystallinities between 4 and 82% at 298 K has been studied.Crystal core contents determined by Raman spectroscopy werealways lower than those determined by density measurements.
