Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

open access: yesResponsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

Rational Design Strategies Toward Efficient and Stable Electrocatalysts for Hydrogen Production via Water Electrolysis: A Comprehensive Review

open access: yesSmall, EarlyView.
ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...

Electrode Oxygen Exchange Enables Polarity‐Controlled Resistive Switching in Topotactic SrCoO2.5

open access: yesSmall, EarlyView.
Electrode chemistry controls the polarity of resistive switching in topotactic SrCoO2.5 heterostructures. Au/SrCoO2.5/Nb‐SrTiO3 (Nb‐SrTiO3: conductive substrate) exhibits polarity‐restricted switching, whereas SrRuO3/SrCoO2.5/Nb‐SrTiO3 switches under both bias polarities.

Unveiling the Structural Advantages in PTFE‐Based Dry‐Processed Electrodes for Sulfide‐Based All‐Solid‐State Batteries via 3D Microstructure‐Resolved Analysis

open access: yesSmall, EarlyView.
Digital twin‐based structural analysis reveals PTFE‐induced structural evolution in dry‐processed electrodes, characterized by increased NCM/LPSCl interfacial contact and homogenized component distributions. These structural features establish a larger active surface area and well‐connected electron and ion transport pathways, enabling enhanced ...

Self‐Reconstructing, Conductive Bismuth Organic Framework Enables Effective Alloying and High‐Capacity Potassium‐Ion Anodes

open access: yesSmall, EarlyView.
An intrinsically conductive two‐dimensional Bi–HHTP framework unites atomically distributed Bi alloying sites with a redox‐active π‐conjugated ligand. Highly confined K–Bi alloying, ligand‐mediated pseudocapacitance, and reversible framework disassembly–reassembly suppress electrode expansion fourfold vs. Bi powder while sustaining 717 mAh g−1, 222 mAh
