Ultrafast Radiative Recombination Engineering in InGaN/GaN Quantum Wells through Temperature, Alloy Fraction and Layer's Width Tuning for Photonics

Advanced Theory and Simulations, EarlyView.
A side‐view schematic illustrating intra‐ and inter‐band optical recombination processes in quantum wells, highlighting applications that depend on carrier dynamics and recombination lifetimes, such as lasers, photodetectors, and solar cells. Abstract Radiative lifetime (RT) on the picosecond to femtosecond scale plays a key role in enabling ultrafast ...

Enhanced Catalytic Cycle of Glucose Oxidation and Reactive Species with ROS and RHS Generation Mediated by Galvanic Engineering of Dual Atomic Sites on Covalent Organic Frameworks Demonstrating Synergistic Bimetal Tumor Treatment

Advanced Science, EarlyView.
A galvanic replacement is used to control dual atomic metals (Au and Ir) on a covalent organic framework (COF) nanoparticle and then coated with hyaluronic acid (HA). Under a specific bimetallic ratio (COF/Aux/Ir1‐x), the optimization can be achieved for the conversion of intracellular nutrients into reactive species (HOCl and O2• ─) and effectively ...

The State of High‐Resolution Imaging of the Human Inner Ear: A Look Into the Black Box

Advanced Science, EarlyView.
High‐resolution imaging of the cochlea is challenged by numerous unique aspects of this organ, where sensorineural cells, crucial for hearing, are too small for conventional modalities like magnetic resonance imaging and computed tomography. This article reviews current imaging techniques, emerging technologies, and innovations aimed at improving ...

Advanced Temperature Design for Dynamic Performance Enhancement of PEMFCs Under High Current Density (HCD)

Advanced Science, EarlyView.
This study presents an innovative temperature difference (TD) design with an in‐plane gradient to optimize cooling channels in proton exchange membrane fuel cells (PEMFCs) under high current density (HCD) loading. The positive temperature difference (PTD) design improves dynamic response by enhancing hydration upstream and mitigating flooding ...

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.
