  2. 21. Investigation of hafnium for biomedical applications : corrosion and tribocorrosion in simulated body fluids

    Author : Jorge Rituerto Sin; Ardian Morina; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Metals have excellent properties, such as high strength, ductility and toughness, which make them the material of choice for many biomedical applications. However, the main drawback of metals is their general tendency to corrode, which is an important factor when they are used as biomaterials due to the corrosive nature of the human body. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pressure sensor; piezoresistance; nanofilms; AlN; microacoustic; Lamb wave; thin film; resonator; sensitivity; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Abstract : Today’s MEMS technology allows manufacturing of miniaturized, low power sensors that sometimes exceeds the performance of conventional sensors. The pressure sensor market today is dominated by MEMS pressure sensors.In this thesis two different pressure sensor techniques are studied. READ MORE

  5. 23. Angular dynamics of small particles in fluids

    Author : Jonas Einarsson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluid mechanics; Particle dynamics; Multi-phase flow;

    Abstract : This thesis concerns the angular motion of small particles suspended in fluid flows. A small particle experiences a hydrodynamic torque due to the local fluid velocity, and this torque leads to rotational motion. When inertial effects are negligible the torque on an ellipsoidal particle is given by Jeffery's theory [Jeffery, G. B. READ MORE
