Publication number: 20210268454Abstract: The present invention generally relates to emulsions, and more particularly, to multiple emulsions. In one aspect, multiple emulsions are formed by urging a fluid into a channel, e.g., by causing the fluid to enter the channel as a “jet.” Side channels can be used to encapsulate the fluid with a surrounding fluid. In some cases, multiple fluids may flow through a channel collinearly before multiple emulsion droplets are formed. The fluidic channels may also, in certain embodiments, include varying degrees of hydrophilicity or hydrophobicity. As examples, the fluidic channel may be relatively hydrophilic upstream of an intersection (or other region within the channel) and relatively hydrophobic downstream of the intersection, or vice versa. In some cases, the average cross-sectional dimension may change, e.g., at an intersection. For instance, the average cross-sectional dimension may increase at the intersection.Type: ApplicationFiled: November 18, 2020Publication date: September 2, 2021Applicant: President and Fellows of Harvard CollegeInventors: David A.

The fluidic channels may also, in certain embodiments, include varying degrees of hydrophilicity or hydrophobicity. In some cases, the average cross-sectional dimension may change, e.g., at an intersection. Unexpectedly, systems such as those described herein may be used to encapsulate fluids in single or multiple emulsions that are difficult or impossible to encapsulate using other techniques, such as fluids with low surface tension, viscous fluids, or viscoelastic fluids. Other aspects of the invention are generally directed to methods of making and using such systems, kits involving such systems, emulsions created using such systems, or the like.Type: GrantFiled: July 21, 2017Date of Patent: December 29, 2020Assignee: President and Fellows of Harvard CollegeInventors: David A.

Publication number: 20160023126Abstract: The present invention generally relates to microfluidics, and to spray drying and other drying techniques. In some aspects, an article containing one or more channels or microfluidic channels is used to mix one or more fluids prior to spray drying. The mixing may occur immediately before the fluids are expelled through a nozzle or other opening into a drying region of the spray dryer. In one set of embodiments, for example, a first fluid is exposed to a second fluid, then the fluids are exposed to air or other gases before being expelled through a nozzle. In certain instances, the first fluid may contain a dissolved species that may precipitate upon exposure to the second fluid; such precipitation may occur immediately before expulsion through a nozzle or other opening, thereby resulting in controlled precipitation as part of the spray drying process.Type: ApplicationFiled: August 25, 2015Publication date: January 28, 2016Applicants: President and Fellows of Harvard College, BASF SEInventors: Adam R. Abate, Julian W.P. Thiele, David A. Weitz, Christian Holtze, Maike Windbergs
