  2. 6. Computational studies on 2D and 3D amorphous solids : Investigation of structure-property relationship

    Author : Emel Gürbüz; Biplab Sanyal; Andreas Larsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous solids; Metallic glasses; Classical molecular dynamics simulations; Thermal transport; Density functional theory; 2D glasses; Vibrational properties; Magnetism; Optical properties;

    Abstract : Amorphous materials represent a large and diverse family, with many questions still remaining unanswered regarding their structure-property relationship. The structural complexity of these materials poses challenges for simulations in contrast to crystalline materials where density func­tional theory (DFT) can be used easily by exploiting the translation symmetry.

  6. 9. Heterogeneous Integration Technologies Based on Wafer Bonding and Wire Bonding for Micro and Nanosystems

    Author : Xiaojing Wang; Göran Stemme; Frank Niklaus; Niclas Roxhed; Shuji Tanaka; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro-electromechanical systems MEMS ; heterogeneous integration; wafer bonding; vacuum packaging; hermetic packaging; wire bonding; magnetic assembly; 2D materials; 2D heterostructures; graphene; hexagonal boron nitride h-BN ; molybdenum disulfide MoS2 ; carbon nanotubes CNTs .; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Heterogeneous integration realizes assembly and packaging of separately manufactured micro-components and novel functional nanomaterials onto the same substrate. It has been a key technology for advancing the discrete micro- and nano-electromechanical systems (MEMS/NEMS) devices and micro-electronic components towards cost-effective and space-efficient multi-functional units.

  7. 10. Numerical Modelling of Dissolved Air Flotation

    Author : Mia Bondelind; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics CFD ; 2D; multiphase flow; one-phase; 3D; turbulence; Dissolved Air Flotation DAF ;

    Abstract : Dissolved Air Flotation (DAF), a well-established treatment method for water containing e.g. dissolved organic matter and Cryptosporidium, has previously been examined experimentally. However, most measuring techniques still suffer from disturbances from air bubbles and intrusion of the measuring equipment into the flow. READ MORE
