Reconfigurable Acoustofluidic Microvortices for Selective Microcargo Delivery

open access: yesAdvanced Science, EarlyView.
This work introduces a frequency‐encoded, reconfigurable acoustofluidic system that overcomes the low throughput and poor selectivity of conventional micro‐delivery methods. By exploiting discrete microbubble resonances to program adaptive microvortex modes, the platform enables real‐time switching and selective guidance of microscale payloads through ...

Spatial Control Over Tether‐Tunable Coordination on Palladium for Divergent Synthesis of Bicyclo[n.1.0]alkanes via Oxidative Cyclopropanation of Enynes

open access: yesAdvanced Science, EarlyView.
We have developed a Pd‐catalyzed oxidative cyclopropanation of 1,n‐enynes employing cyclic diacyl peroxides as bifunctional reagents that serve as both tether‐tunable oxidants and spatially controlled dicarboxylate anions. ABSTRACT Bicyclo[n.1.0]alkanes are highly valuable scaffolds in drug discovery and synthetic chemistry.

Nucleoside‐Based Hydrogel Platform Synergizes with Photothermal Effects for Enhanced Biofilm Eradication Against Periodontitis

open access: yesAdvanced Science, EarlyView.
A synergistic antibiofilm hydrogel platform (ZBAg@FNP) is developed by encapsulating an organic small‐molecule photothermal agent (FNP) within a silver ion‐mediated supramolecular hydrogel (ZBAg), enabling photothermal disruption of biofilm integrity and controlled Ag⁺ ion release upon irradiation.

Basal Plane Activation of SnS2 Thin‐Film by Fluorine Doping for Selective Solar‐Driven CO2 Reduction With Enhanced Quantum Efficiency

open access: yesAdvanced Science, EarlyView.
The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach

Enhanced Photocatalytic CO2 Reduction Performance by External Electric Field‐Driven Charge Separation on Interdigitated Micro‐Spacing Structure

open access: yesAdvanced Science, EarlyView.
An external electric field‐enhanced photocatalytic system is developed using interdigitated electrodes with 100 µm spacing to overcome the liquid‐phase limitations of traditional PEC. The induced high‐intensity electric field effectively drives the directional migration of charge carriers under low voltage. This strategy significantly suppresses charge
