Recomposable Layered Metasurfaces for Wavelength‐Multiplexed Optical Encryption via Modular Diffractive Deep Neural Networks

open access: yesAdvanced Functional Materials, EarlyView.
Modular diffractive deep neural network metasurfaces encode and reconstruct holograms across layer combinations and wavelengths, enabling secure, multifunctional operation. Each layer acts independently yet composes jointly, yielding up to m(2N −1) channels for m wavelengths and N layers.

Multistackable, Domino‐Overlapped CNT Scaffolds Homogeneously Hybridized with BTO‐P(VDF‐TrFE) for High‐Performance Piezoelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
A multilayer‐stackable carbon nanotuber (CNT) scaffold‐based piezoelectric nanogenerator (CPENG) with domino‐patterned CNT pillars presents high, stable output (12.3 V, size of 1 cm × 1 cm) over 2000 cycles, operates across a wide temperature range, and efficiently converts energy from real‐life stimuli through optimized CNT length, layer stacking, and

Regulating digital platforms

open access: yes, 2019
In this issue we pursue our exploration of whether and how digital platforms, especially digital platforms as applied to the network industries, should and could be regulated. Indeed, as of recently, attention paid to these emerging digital platforms is exploding. Most of the related publications aim at making recommendations as to whether, and if yes,

An Ionic Gelation Powder for Ultrafast Hemostasis and Accelerated Wound Healing

open access: yesAdvanced Functional Materials, EarlyView.
An ultrafast ionic gelation‐activated hemostatic powder (AGCL) forms a hydrogel within ≈1 s upon contact with blood‐derived calcium ions. The AGCL powder enables rapid hemorrhage control, strong tissue adhesion, and enhanced healing. The powder's pre‐crosslinked polymer network ensures high blood uptake and stability, offering effective treatment for ...
