Navigating Classical and Nonclassical Realms of Nucleation and Crystallization

Small, EarlyView.
Classical nucleation and growth theories have long been foundational, yet recent nonclassical concepts have challenged and refined our understanding of solid‐state genesis. This paradigm shift introduced new, often ambiguous vocabulary. Here, we clarify key concepts, correct common misconceptions, and provide a terminological field guide across systems,

Contactless Detection of Giant Helicity‐Dependent Photovoltage in Chiral 2D Perovskites

Small, EarlyView.
A novel contactless probe—circularly polarized time‐resolved surface photovoltage spectroscopy is demonstrated to evaluate helicity‐dependent charge separation dynamics without the need for electrical contacts. Application of this novel methodology to chiral 2D perovskites reveals giant transient surface photovoltage anisotropy.

Thermo‐Kinetic Design of Magnesiothermic Reduction for Morphology‐Retaining Porous Si@C Anodes

Small, EarlyView.
Balancing Mg‐vapor supply and surface consumption during magnesiothermic reduction suppresses particle aggregation and preserves monodisperse morphology in porous Si@C spheres. The resulting architecture improves transport uniformity and reduces degradation within the electrode, leading to more stable high‐capacity cycling than aggregated counterparts ...

High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

Smart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...
