Single‐Crystal PZT‐Driven Organic Piezo‐Phototronic Adaptive Transistors Toward Advanced Spatiotemporal Visual Computing

open access: yesAdvanced Science, EarlyView.
Here, we propose a single‐crystal PZT‐based piezo‐phototronic organic adaptive memory transistor (OAMT), achieving a record memory window capacity factor (γ) of 0.87 at a low SS of 200 mV/decade via efficient multi‐field control. The device achieves a high recognition accuracy ∼ 90% in neuromorphic simulations, demonstrates robust fault tolerance under

Transient Terahertz Oscillations During Photoinduced Polarization Topology Reconfiguration in Ferroelectric Superlattices

open access: yesAdvanced Science, EarlyView.
Terahertz resonances in crystalline heterostructures could close a spectral gap between conventional electronics and photonics while opening new windows on non‐equilibrium lattice dynamics. Femtosecond optical screening of the depolarization field in epitaxial PbTiO3/SrTiO3 superlattices launches a collective polar mode that oscillates near 1 THz and ...

A Dual‐Piezoelectric Metal–Organic Cage/COF Z‐Scheme Heterojunction for Solar‐Mechanical Water Splitting

open access: yesAdvanced Science, EarlyView.
A dual‐piezoelectric Z‐scheme heterojunction is constructed by integrating a piezoelectric metal–organic cage (MOC‐FA3) with a β‐ketoenamine‐linked covalent organic framework (S‐COF). This design enables efficient solar‐mechanical energy conversion, achieving remarkable piezo‐photocatalytic pure water splitting for simultaneous H2 and H2O2 production ...

Infrared Machine Vision System Based on Te NWs‐Au NPs Plasmonic Optoelectronic Memristor for Motion Detection

open access: yesAdvanced Science, EarlyView.
A plasmonic optoelectronic memristor based on Te nanowires‐Au nanoparticles/ι‐carrageenan enables IR‐programmed and visiblelight‐erased non‐volatile conductance. The all‐photonic write/erase scheme supports in‐sensor logic and real‐time motion detection in darkness.

Illuminating Mitochondrial RNA G‐Quadruplexes as Structural Brakes on RNA Granule Assembly and OXPHOS

open access: yesAdvanced Science, EarlyView.
A new fluorescent probe, MitoQUMA, brings mitochondrial RNA G‐quadruplexes (mtRNA G4s) into view in live cells. This tool reveals that excessive mtRNA G4 formation halts mitochondrial RNA granule (MRG) assembly, opposite to the phase‐separation role of cytoplasmic RNA G4s. A chemical genetic screen further identifies a Wnt/β‐catenin–GRSF1–mtRNA G4 axis
