  5. 3. Microfluidics Separation and Analysis of Biological Particles

    Author : Jason Beech; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Point-of-care; Lab-on-a-chip; Microfluidics; Separation science; Deterministic Lateral Displacement; morphology; deformability; Fysicumarkivet A:2011:Beech;

    Abstract : In the last decade, powerful communication and information technology in the form of the mobile phone has been put into the hands of more than 50% of the global population. In stark contrast, a lack of access to medical diagnostic technology with which to diagnose both communicable and non-communicable diseases will mean that many of these people will die of easily treatable conditions.

  6. 4. Development of Multi-grit cBN Grinding Wheel for Crankshaft Grinding

    Author : Nastja Macerol; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive; cBN; grinding; vitrified bond; grit shape; grit concentration; morphology; aspect ratio; crankshaft; grinding wheels;

    Abstract : Crankshaft is a geometrically challenging component to grind. Over the years a number of grinding strategies have been developed to overcome thermal damage issues and excessive wheel wear. Radial and angular plunge processes have been adopted on some of the production machines. Recently a new, temperature-based strategy, has been proposed. READ MORE

  7. 5. Influence of Microstructure in Machining of Nickel and Nickel-Iron Based Alloys

    Author : Stefan Olovsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wear mechanisms; Simulation; Tool wear; Burr; Meta-modelling; Inconel 718; Metal cutting; Superalloy; Waspaloy; Chip morphology; Notch wear; Alloy 718; JMatPro;

    Abstract : Superalloys are used in applications such as turbines, steam power plants and nuclear power systems in components that require good high temperature properties and/or corrosion resistance. They are classified as difficult-to-cut materials and hence, from a sustainable production point of view, tool wear and tool life are major factors when machining these alloys. READ MORE
