Journal ArticleDOI
Dripping to jetting transitions in coflowing liquid streams.
Andrew S. Utada,Alberto Fernandez-Nieves,Alberto Fernandez-Nieves,Howard A. Stone,David A. Weitz +4 more
TL;DR: It is shown that in a coflowing stream this transition from dripping to jetting is characterized by a state diagram that depends on the capillary number of the outer fluid and the WeberNumber of the inner fluid.
Journal ArticleDOI
Designer emulsions using microfluidics
Rhutesh K. Shah,Ho Cheung Shum,Amy C. Rowat,Daeyeon Lee,Jeremy J. Agresti,Andrew S. Utada,Liang-Yin Chu,Liang-Yin Chu,Jin Woong Kim,Alberto Fernandez-Nieves,Alberto Fernandez-Nieves,Carlos J. Martinez,Carlos J. Martinez,David A. Weitz +13 more
TL;DR: In this paper, the authors describe new developments for the controlled fabrication of monodisperse emulsions using microfluidics and use glass capillary devices to generate single, double, and higher order emulsion with exceptional precision.
Journal ArticleDOI
Soft colloids make strong glasses.
Johan Mattsson,Hans M. Wyss,Hans M. Wyss,Alberto Fernandez-Nieves,Alberto Fernandez-Nieves,Kunimasa Miyazaki,Kunimasa Miyazaki,Zhibing Hu,David R. Reichman,David A. Weitz +9 more
TL;DR: It is shown that deformable colloidal particles, when studied through their concentration dependence at fixed temperature, do exhibit the same variation in fragility as that observed in the T dependence of molecular liquids at fixed volume.
Journal ArticleDOI
Fabrication of Monodisperse Gel Shells and Functional Microgels in Microfluidic Devices
TL;DR: A flexible and straightforward method for generating monodisperse suspensions of new microgelbased materials using a capillary microfluidic technique, which enabled us to generate and precisely control the size of the microgel-based particles without sacrificing the physical response of the resulting microgels.
Journal ArticleDOI
Dripping, Jetting, Drops, and Wetting: The Magic of Microfluidics
Andrew S. Utada,Liang-Yin Chu,Alberto Fernandez-Nieves,Darren Roy Link,Christian Holtze,David A. Weitz +5 more
TL;DR: Weitz et al. as mentioned in this paper described how simple microfluidic devices can be used to control fluid flow and produce a variety of new materials based on the concepts of coaxial flow and hydrodynamically focused flow, used alone or in various combinations.
