Sub‐1000 °C Sintering of Protonic Ceramic Electrochemical Cells via Microwave‐Driven Vapor Phase Diffusion

open access: yesAdvanced Materials, EarlyView.
A transformative microwave‐driven vapor‐phase sintering strategy enables densification of proton‐conducting electrolytes at 980 °C, reducing the sintering temperature by over 500 °C and addressing a major bottleneck toward PCEC manufacturing. Abstract Protonic ceramic electrochemical cells (PCECs) hold significant promise for efficient power generation

Increasing the Stability of Deep Blue Phosphor‐Sensitized OLEDs Using the Polariton‐Enhanced Purcell Effect

open access: yesAdvanced Materials, EarlyView.
The polariton‐enhanced Purcell (PEP) effect is demonstrated to enhance the stability of the deep blue phosphor‐sensitized fluorescent (PSF) OLEDs by 3.1 X compared to PSF diodes lacking this effect. In addition, PSF‐OLEDs exhibit reduced EQE roll‐off and deep blue color emission.

Ion Valency as a Molecular Switch for Salt‐Resistant Underwater Adhesion

open access: yesAdvanced Materials, EarlyView.
Monovalent K+ ions weaken adhesion by forming K+‐π complexes with weak bridging capacity. In contrast, multivalent cations like Y3+ enhance adhesion by forming stable π‐cation‐π bridging networks, which are resistant to salt and capable of compensating for the loss of native π–π and NH3+‐π interactions.

Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

open access: yesAdvanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...
