1. 1. Alternative binder hardmetals for steel turning

   Författare :Lisa Toller; Susanne Norgren; Hans-Olof Andrén; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardmetal; cemented carbide; alternative binder; steel turning; scratch testing; plastic deformation; EBSD; transformation toughening; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

   Sammanfattning : The goal of this work is to understand how the wear and deformation mechanisms of hardmetalinserts change when the cobalt binder phase is replaced with a dierent metal or analloy. The focus is on inserts for steel turning. The work presented in this licentiate thesisconsists of the rst steps. LÄS MER

3. 2. ICME guided development of cemented carbides with alternative binder systems

   Författare :Martin Walbrühl; John Ågren; Annika Borgenstam; Henrik Larsson; Claudio Miguel Lousada Patricio; Jan Qvick; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cemented carbide; ICME; Materials Design; alternative binder; hardness; AIMD; liquid diffusion; frozen-in solubilities; DICTRA; surface gradients; labyrinth factor; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : The development of alternative binder systems for tungsten carbide (WC) based cemented carbides has again become of relevance due to possible changes in EU regulations regarding the use of Cobalt (Co). A framework for the ICME (Integrated Computational Materials Engineering) based Materials Design is presented to accelerate the development of alternative binder systems. LÄS MER

4. 3. Phase field modeling of precipitation reactions in miscibility gap systems

   Författare :Deepjyoti Mukherjee; Joakim Odqvist; Henrik Larsson; Benoît Appolaire; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precipitation; Discontinuous; Diffusion; Boundary; Phase-field; Miscibility-gap; Cemented carbides; Binary alloys; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : As a backbone to the cutting tools and rock drilling industry, cemented carbides have been used widely due to their high hardness and wear resistance. Most commercially used cemented carbides contain a hard phase made of Tungsten carbide (WC) and a binder phase which is generally ductile. LÄS MER

5. 4. DNA-Assisted Immunoassays for High-Performance Protein Analyses

   Författare :Junhong Yan; Masood Kamali-Moghaddam; Ulf Landegren; Christer Wingren; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proximity ligation assay; magnetic beads; conjugation; phosphorylation; affinity binder; protein complexes; recombinant binder; sensitivity; specificity; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

   Sammanfattning : Proteins play important roles in most cellular functions, such as, replication, transcription regulation, signal transduction, for catalyzing chemical reaction, etc. Technologies developed to identify proteins rely either on observing their own properties such as charge, size, mass to charge ratio or sequence composition; or on using affinity reagents that recognize specific protein targets.
