  1. 1. CVD on Iron Powder - Using Fluidising Bed Techniques

    Författare :Lars Nilsson; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium oxide; alumina; chemical vapour deposition; eddy current losses; FBR; iron; fluidising bed reactor; powder; SiO2; SMC; TiO2; Al2O3; soft ma etic com sites; CVD;

    Sammanfattning : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. LÄS MER

  3. 2. On the Immune Regulation of Bone Response to Biomaterials

    Författare :Ricardo Trindade; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomaterial; Immune System; Osseointegration; Foreign body reaction; Immune modulation; Titanium; Copper; Polyether ether ketone; PEEK;

    Sammanfattning : Osseointegration is the biological basis for bone anchorage of oral implants, and revolu-tionized the replacement of lost teeth. It is also applied in bone anchored hearing aids and limb replacement in amputees. LÄS MER

  4. 3. Development of coke properties during the descent in the blast furnace

    Författare :Maria Lundgren; Seshadri Seetharaman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The efficiency in use of reducing agents in blast furnace (BF) ironmaking has been significantly improved over the years. At most blast furnaces, auxiliary fuels are injected to replace some of the coke. To further reduce carbon consumption, prevention of losses and modification of raw materials or process conditions are required. LÄS MER
