Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Dynamics of the Gierer–Meinhardt reaction–diffusion system: Insights into finite-time stability and control strategies

Partial Differential Equations in Applied Mathematics
This study delves into the dynamics of the Gierer–Meinhardt (GM) reaction–diffusion (RD) system, focusing on finite-time stability (FTS) and synchronization (FTSYN) within integer-order spatiotemporal partial differential frameworks.

Synchronization in the presence of distributed delays

, 2016
We study systems of identical coupled oscillators introducing a distribution of delay times in the coupling. For arbitrary network topologies, we show that the frequency and stability of the fully synchronized states depend only on the mean of the delay ...

Enhanced dynamic support strategies of grid-forming-PMSG based on DC-voltagesynchronization: Frequency and Q support perspective

International Journal of Electrical Power & Energy Systems
The DC-Voltage Synchronization based Grid-Forming PMSG has voltage source characteristics, e.g. frequency and reactive power support function, however, the support capability is limited, and the regulation potential is not fully utilized.

Mechanotransducing Organic Electrochemical Diode for Crosstalk‐Inhibited Artificial Skin

Advanced Functional Materials, EarlyView.
An innovative approach is presented to a stretchable mechanotransducing diode that unifies rectification and tactile‐sensing functionality. This approach enables to fabricate the diode that maintains a large rectification ratio (5 × 102) at a high operational frequency (100 Hz).

Transient synchronization stability of a weak‐grid connected VSC considering the interaction of outer control loops and PLL dynamics

IET Renewable Power Generation
Since these large‐scale renewable power generation (RPGs) stations are always located far away from load centres, voltage source converters (VSCs) always operate in weak‐grid connected conditions, due to the long distance of transmission line and ...

Atomic‐Level Dual‐Cation Engineering Enables High‐Performance Na4VMn(PO4)3 Cathodes for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
Dual‐cation site engineering unlocks stable and fast sodium storage in Na4VMn(PO4)3 cathodes. Li+ at Na2 suppresses Jahn‐Teller distortion, while K+ at Na1 expands ion channels, enabling synchronized V/Mn redox and quasi‐single‐phase kinetics. This atomic‐level strategy achieves ultralong cycling stability, high‐rate capability, and full cell viability
