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

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

   Sammanfattning : 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. LÄS MER

3. 22. Analytical photoacoustic model of laser-induced ultrasound in a planar layered structure

   Författare :Erika Svanström; Erik Olsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Sammanfattning : A way of describing photoacoustic measurement techniques is listening to light. Another way is as sensor techniques for characterisation of materials by means of light and sound interacting with the material under investigation. LÄS MER

4. 23. Coercive estimates for the solutions of some singular differential equations and their applications
