Release of Encapsulated Content in Microdroplets
Analytical Sciences, 2011 A method for releasing the content of microdroplets by changing the channel wall wettability is proposed. The contents of aqueous droplets were released to the continuous phase by inverting 10-µm-sized W/O droplets into O/W ones in a 2-µm-deep hydrophilic channel. The combination of "encapsulation" and "release" in microdroplets facilitates micromixing

Advanced Science, EarlyView.ABSTRACT Translating dynamic liquid‐liquid phase separation into robust solid‐state architectures remains a challenge in materials engineering. Here, we report a composition‐driven interfacial assembly strategy that couples supramolecular coacervation with metal‐phenolic coordination to engineer tunable fungicide carriers.

The Air–Water Interface as the Reaction Site in Microdroplets: A Case Study of Thiol Oxidation
ChemistryEuropeThe air–water interface plays a crucial role in microdroplet reactions. In this study, we investigated the oxidation of two thiol molecules on water microdroplets: 2‐mercaptosuccinic acid (MSH) and 3‐phenyl‐2‐sulfanylpropanoic acid (PSH), with PSH being ...

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs
Droplet, EarlyView.Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...
