1. 1. Capillarity and wetting of non-Newtonian droplets

   Författare :Yuli Wang; Gustav Amberg; Daniel Bonn; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dynamic wetting; contact line; diffusive interface; viscoelasticity; non-Newtonian; microfluidics; droplet impact; droplet spreading; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Capillarity and dynamic wetting of non-Newtonian fluids are important in many natural and industrial processes, examples cover from a daily phenomenon as splashing of a cup of yogurt to advanced technologies such as additive manufacturing. The applicable non-Newtonian fluids are usually viscoelastic compounds of polymers and solvents. LÄS MER

5. 4. Droplet microfluidics for screening and sorting of microbial cell factories

   Författare :Sara Björk; Helene Svahn Andersson; Håkan Jönsson; Christoph Merten; KTH; []
   Nyckelord :Droplet microfluidics; Cell factories; High-throughput screening; Cell culture; Bioteknologi; Biotechnology;

   Sammanfattning : Cell factories are cells that have been engineered to produce a compound of interest, ranging from biopharmaceuticals to biofuels. With advances in metabolic engineering, the number of cell factory variants to evaluate has increased dramatically, necessitating screening methods with increased throughput. LÄS MER

7. 5. Rapid wetting - influence of surface geometry and fluid properties

   Författare :Susumu Yada; Fredrik Lundell; Shervin Bagheri; Minh Do-Quang; Gustav Amberg; Jacco Snoeijer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wetting; spreading; surface structures; droplet; contact line; two-phase flow; non-Newtonian flow; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Wetting of a liquid on a solid surface is ubiquitous in everyday life, such as morning dew on a plant leaf and raindrops hitting on a glass window. However, this phenomenon is far away from being completely understood. LÄS MER
