  2. 6. Alloy Design for High-Entropy Alloys: Predicting Solid Solubility, and Balancing Mechanical Properties and Oxidation Resistance

    Author : Saad Ahmed Sheikh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : High-entropy alloys (HEAs) comprise of multi-principal elements in equi-atomic or near equi-atomic percentage. HEAs are considered as potential structural materials for high temperature applications, which require alloy design for optimum mechanical properties. READ MORE

  4. 7. Alloy Design and Optimization of Mechanical Properties of High-Entropy Alloys

    Author : Saad Ahmed Sheikh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ductility; topologically closed-pack TCP and geometrically closed-pack GCP phase; alloy design; mechanical properties; High-entropy alloys; refractory high-entropy alloys; valence electron concentration;

    Abstract : High-entropy alloys (HEAs) are described as alloys containing multi-principal elements in equal or close to equal atomic percentage. HEAs are considered as potential structural materials for high-temperature applications; where alloy design and optimization of mechanical properties is extremely critical. READ MORE

  5. 8. Screening Investigations of Novel Nitrogen Donor Ligands

    Author : Mikael Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; lanthanides; transmutation; actinides; BTBP; solvent extraction; screening; partitioning;

    Abstract : With an increasing global demand for electricity, nuclear power plays an important role. The nuclear power industry is in different stages of development throughout the world. READ MORE

  6. 9. Aerosol-water interaction at sub and super-saturated regimes : From small scale molecular mechanisms to large scale atmospheric models

    Author : Narges Rastak; Ilona Riipinen; Maria Kanakidou; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; miljövetenskap; Environmental Sciences;

    Abstract : The term “atmospheric aerosol” refers to solid or liquid particles suspended in the atmosphere. Atmospheric aerosols influence the Earth’s energy budget directly by scattering and absorbing radiation (known as the direct aerosol effect) and indirectly by acting as cloud condensation nuclei (CCN) and ice nucleating particles and thereby modifying cloud properties (known as the indirect aerosol effect).

  7. 10. Diffusion in Poly(vinyl alcohol) and Polyethylene as Determined by Computational Simulations and Modeling

    Author : Gunnar Karlsson; KTH; []
    Keywords : Molecular dynamics; simulation; modeling; polymer; poly vinyl alcohol ; polyethylene; water; oxygen; limonene; solute; diffusion; transport properties;

    Abstract : Poly(vinyl alcohol) and polyethylene polymer systems werebuilt in order to study their transport properties (diffusion).First a verification of the AMBER force field was conducted fora poly(vinyl alcohol) system built from a chain with 145repeating units. NPT-molecular dynamics simulations attemperatures between 400 and 527 K were performed. READ MORE
