1. 26. Disperson and Flocculation in a Dry Mat-Forming Process

   Författare :Robert Rundqvist; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The absorption cores in disposable nappies, incontinence pads and female hygiene products are manufactured by a dry mat-forming process. Cellulose fibers and super-absorbing particles are suspended in air and blown onto a forming wheel on which the cores are formed. LÄS MER

3. 27. Bioparticle Manipulation using Acoustophoresis and Inertial Microfluidics

   Författare :Muhammad Asim Faridi; Aman Russom; Martin Wiklund; Jonas Tegenfeldt; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biotechnology; Bioteknologi;

   Sammanfattning : Despite the many promising advances made in microfluidics, sample preparation remains the single largest challenge and bottleneck in the field of miniaturised diagnostics. This thesis is focused on the development of sample preparation methods using active and passive particle manipulation techniques for point of care diagnostic applications. LÄS MER

4. 28. Experimental Studies of Complex Flows through Image-Based Techniques

   Författare :Gabriele Bellani; FredrIk Lundell; James Olsen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : This thesis deals with the development of experimental techniques for the study of complex flows inspired to a large extent by the papermaking process. In particular one part of this thesis is devoted to the development of laboratory experiments based on index-of-refraction matching and imaging techniques to study the behavior of dilute and concentrated suspension of elongated particles.
