1. 1. Synovial fluid components as synergistic lubricants in articular joint models

   University essay from KTH/Kemi

   Author : Sixuan Li; [2019]
   Keywords : synergistic lubrication; synovial fluid; biolubrication; DPPC; hyaluronic acid; Mini-Traction Machine; macro- and microscale; profilometer;

   Abstract : The excellent lubrication present within mammalian synovial joints attracted scientific interest, and some close-to-realistic models were applied to study the mechanism in vitro. In this project, the synergistic lubrication of synovial fluid was investigated by using 1,2-Dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC), hyaluronic acid (HA), and phosphate-buffered saline (PBS buffer) to mimic the synovial fluid.

3. 2. Study of the wear mechanisms for drill bits used in core drilling

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Emy Guttenkunst; [2018]
   Keywords : ;

   Abstract : The thesis work was made in cooperation with the I-EDDA project who evaluates the drill equipment used in core drilling. The aim of this work was to determine how and why the drill bits are worn. READ MORE

4. 3. Determination of homogenized viscoelastic properties of porous frame structures based on the microstructure geometry and solid constituent viscoelastic properties

   University essay from KTH/Farkost och flyg

   Author : Prasanth Narayana Srinivasa; [2011]
   Keywords : ;

   Abstract : Polymer based porous materials largely exhibit viscoelastic properties which is a consequence of the viscoelastic nature of the constituent solid. If the constitutive relation for the constituent solid is known, then it is of interest to investigate how this constitutive relation of the solid at the microscale influences the macroscopic properties of the porous structure.
