Multifunctional Fluidic Units for Emergent, Responsive Robotic Behaviors

open access: yesAdvanced Materials, EarlyView.
A multifunctional reconfigurable fluidic unit can be used as sensor, valve and actuator is presented. A unique configuration combines the features of the three components as a Responsive self‐oscillating actuator. The remarkable versatility of the fluidic unit is demonstrated by building different robots with the same fluidic units only by varying ...

Spatially Encoded Polaritonic Ultra‐Strong Coupling in Gradient Metasurfaces with Epsilon‐Near‐Zero Modes

open access: yesAdvanced Materials, EarlyView.
Dielectric dual gradient metasurfaces supporting quasi‐bound‐states‐in‐the‐continuum are leveraged to spatially encode both the spectral and coupling parameter space and demonstrate ultra‐strong coupling to an epsilon‐near‐zero mode in an ultra‐thin SiO2 layer.The platform achieves exceptional mode overlap, reaching a normalized coupling strength of η =

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

open access: yesAdvanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Revealing How Acid Sites Enhance the Electrocatalytic Glycerol Oxidation Performance on Pt Loaded Zeolite‐Carbon Composite Materials

open access: yesAdvanced Materials, EarlyView.
In the work reported herein, the catalytic effects of acid sites on electrocatalytic glycerol oxidation reaction are investigated by using a novel catalytic material system that integrates Pt metal sites with acidic Al sites. Abstract The catalytic role and function of acid sites in solid acid catalysts, such as zeolites, are well understood in the ...
