5. 3. Cavitation Erosion Mechanisms in Cast Irons

   Author : Marcio Freitas de Abreu; Stefan Jonsson; Jessica Elfsberg; Matevz Dular; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : The research presented in this thesis investigated the mechanisms by which cavitation erosion damage develops in lamellar graphite iron (LGI) and austempered ductile irons (ADIs). This has been achieved by image sequences of surface erosion on test samples in tandem with weight change measurements. READ MORE

6. 4. Polymer-shelled Ultrasound Contrast Agents : Characterization and Application

   Author : Dmitry Grishenkov; Leif Kari; Lars-Åke Brodin; Michel Versluis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultrasound; contrast agents; microbubbles; polymer; perfusion; Acoustics; Akustik; Material physics with surface physics; Materialfysik med ytfysik; Cardiovascular medicine; Kardiovaskulär medicin; Cardiology; Kardiologi;

   Abstract : Ultrasound-based imaging technique is probably the most used approach for rapid investigationand monitoring of anatomical and physiological conditions of internal organs and tissues.Ultrasound-based techniques do not require the use of ionizing radiation making the tests anexceptionally safe and painless.
