Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

open access: yesAdvanced Functional Materials, EarlyView.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential

Quantifying Electron and Ion Transfers in Contact Electrification with Ionomers

open access: yesAdvanced Functional Materials, EarlyView.
The concurrent existence of both electron and ion transfers in solid‐ionomer contact electrification is reported. The ion transfer contributes significantly to the process of contact electrification, especially at high humidity, although only less than 2% of ions participate in the ion transfer, suggesting that there is room for further performance ...

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Topological Insulator Layered Bi2Te3 Based 3D‐Printed Nanocarbon Electrode for Rechargeable Aqueous Ammonium‐Ion Battery

open access: yesAdvanced Functional Materials, EarlyView.
In this work, Bi2Te3 is integrated into a 3D‐printed nanocarbon electrode for NH4+ storage. A rocking‐chair battery with CuHCF as the cathode delivers a high energy density of 134.8 Wh kg−1 and a power density of 1800 W kg−1. The design allows easy recovery of carbon additives, promoting sustainability and recyclability in next‐generation aqueous ...
