In this work, we highlight a unique material platform capable of producing three distinct room temperature (RT) photoluminescence (PL) resonances from spatially separated regions composed of a heterobilayer (HBL), a homobilayer (HoBL), and an heterotrilayer (HTL) transition metal dichalcogenide (TMD) heterostructures configuration on a highly ...

Engineering Energy Harvesting Pathways in Mn‐Yb‐Doped Perovskite Nanocrystals
Mn‐Yb codoping in metal halide perovskite nanocrystals establishes dual‐channel energy reservoirs that capture charge carriers and drip‐feed them back to the host on millisecond timescales. This synergistic recycling mechanism overcomes prompt nanosecond recombination limitations, enabling an eight‐fold enhancement in photocatalytic CO2 reduction ...

Modeling Light‐Induced Synaptic Behavior and Visual Memory of Azopolymeric Compounds
In the framework of neuromorphic hardware it is essential to predict the evolution of the internal state of the devices mimicking synaptic functionalities to perform in‐silico modeling of specific computational tasks. Here, we provide a rate‐balance equation model to describe the synaptic‐like response of light‐actuated azopolymeric compounds and ...

Stress‐to‐Light Conversion in an Earth‐Abundant Oxide Semiconductor
Stress‐to‐light conversion in solids represents a unique photonic functionality, yet it has never been realized in a chemically simple and sustainable material. Here, we show that sustainable semiconductor ZnO exhibits strong near‐infrared (NIR) luminescence under elastic stress when defect‐engineered to stabilize the p‐type state.

Formation of Light‐Emitting Defects in Ag‐Based Memristors
How does a memristor begin to emit light‐before it even conducts? This work reveals that nanoscale silver clusters form, diffuse, and aggregate during activation, driving early photoluminescence ahead of current flow. Linking these precursor dynamics to later electroluminescence, it uncovers the origins of light emission and enables precise control of ...

Kinetic–energetic projection of time‐resolved photoluminescence reveals that charge‐transfer injection acts as a universal bottleneck in organic solar cells. A physics‐constrained Bayesian framework identifies an emergent effective CT injection rate governing the trade‐off between charge generation and nonradiative energy loss.

Tuning the Magnetic Phase Transitions in TbMn2‐xTixSi2 (x = 0–0.3)
ABSTRACT Magnetocaloric materials receive considerable attention as promising candidates for next‐generation energy‐efficient and environmentally benign solid‐state refrigeration technologies. These materials exhibit the magnetocaloric effect (MCE), whereby heat is absorbed or released upon the application or removal of a magnetic field. In this study,

Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.
