  1. 21. Fabrication and Functionalization of Graphene and Other Carbon Nanomaterials in Solution

    Författare :Erika Widenkvist; Ulf Jansson; Reine Wallenberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphene; Functionalization; Carbon nanotubes; Carbon nanosheets; Organic chemistry; Organisk kemi; Organisk kemi; Organic Chemistry;

    Sammanfattning : In the last decades several new nanostructures of carbon have been discovered, including carbon nanotubes (CNTs), and the recently discovered 2-dimensional graphene. These new materials exhibit extraordinary and unique properties—making them extremely interesting both for fundamental science and for future applications. LÄS MER

  3. 22. An improvisational, practice-oriented approach to innovation : Examples from the fashion industry

    Författare :Sara Öhlin; Ali Yakhlef; Jan Löwstedt; Louise Wallenberg; Matt Watson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; innovation; practice; fashion; improvising; planning; routines; practice memory; företagsekonomi; Business Administration;

    Sammanfattning : Fashion and innovation interrelate in multiple and complex ways. With its routinized, cyclical production yet creative context, the fashion industry is sustained by an ongoing tension between stability and change. As a consequence, innovative activities are performed in everyday work routines. LÄS MER

  4. 23. I företagshistoriens marginaler : Familj, fostran och fortlevnad i sekelskiftets dynastier

    Författare :Stina Malmén; Therese Nordlund Edvinsson; Paulina de los Reyes; Charlotte Holgersson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dynasty; family firm; social reproduction; public private; Wallenberg; Ekman; ekonomisk historia; Economic History;

    Sammanfattning : The dissertation addresses the question of power structures in corporate families. Two leading Swedish corporate dynasties during the pre-first world war era are examined from an intersectional perspective: the Ekman and the Wallenberg families. LÄS MER

    Sammanfattning : AbstractIn the summer of 1944, Raoul Wallenberg was sent to Budapest as a representative of the Swedish Foreign Office. His assignment was to save Hungarian Jews with connections to Sweden. LÄS MER

  7. 25. On efficient and adaptive modelling of friction damping in bladed disks

    Författare :Mohammad Afzal; Leif Kari; Ines Lopez Arteaga; Muzio M Gola; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High cycle fatigue; Friction contact; Jacobian matrix; Shroud contact; Strip damper; Multiharmonic balance method; Contact stiffness; Cyclic symmetry; Nodal diameter; Magnetostrictive actuator; Magnetic field; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : This work focuses on efficient modelling and adaptive control of friction damping in bladed disks. To efficiently simulate the friction contact, a full-3D time-discrete contact model is reformulated and an analytical expression for the Jacobian matrix is derived that reduces the computation time drastically with respect to the classical finite difference method.
