Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

Ultrafast Transitions in X‐Ray Irradiated Solids

Contributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Ferroelectric‐Enhanced Self‐Driven Solar‐Blind Photodetector in the GaN‐In2Se3 p‐n Junction

Information &Functional Materials, EarlyView.
We designed a self‐driven GaN‐In2Se3 p‐n junction photodetector with high performance, leveraging the synergy of the built‐in electric field and ferroelectric polarization. At a bias voltage of 0 V, the photodetector exhibits excellent self‐driven performance in the SBUV region with responsivity of 54.95 mA/W and detectivity of 1.66 × 1012 Jones ...

Ultrafast in‐memory computing and highly efficient deep neural networks driven by phase‐change memory materials with partially amorphous state transitions

InfoScience, EarlyView.
This work addresses challenges including the nonlinear weight‐conductance update and the trade‐off between increasing melting uniformity and reducing solid‐to‐liquid transition time. It utilizes all four melting states to create an integrated framework for attaining in‐memory computing and deep neural network applications. The framework achieves a near‐
