Heterogeneous Single/Dual‐Atom Electrocatalysts in Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review summarizes recent advances in single‐atom and dual‐atom electrocatalysts for high‐performance lithium–sulfur batteries. The text systematically covers the classification of catalysts by active metal centers, key synthesis methods, in situ characterization for mechanistic insights, and electrocatalytic mechanisms.

Boosting the Photoluminescence of Au@Cu12 Nanoclusters via Strategic Fluorine‐Atom Ligand‐Shell Engineering

Journal of the Chinese Chemical Society, EarlyView.
The photophysical performance of gold‐doped copper‐rich nanoclusters can be tuned by surface functionalization. Subtle ligand modification enhances intermolecular interactions, thereby reducing nonradiative decay and markedly improving photoluminescence. Comparative photographs and quantum yield values (Φ = 55% vs.

When Fat Goes Astray: Your Liver and Pancreas Get Into Trouble

Portal Hypertension &Cirrhosis, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) and intrapancreatic fat deposition (IPFD) are both common manifestations of ectopic fat accumulation. Although they share multiple risk factors, they also show notable differences in pathological features, standardization of diagnosis, and research maturity.

Safety, efficacy, pharmacokinetics, and mechanisms of novel 10B‐boronophenylalanine combined with a radio‐frequency quadrupole accelerator in boron neutron capture therapy: A preclinical study in head and neck squamous cell carcinoma

Precision Radiation Oncology, EarlyView.
This study demonstrates that the novel 10B‐BPA‐based BNCT system, combined with an RFQ accelerator, effectively targets head and neck squamous cell carcinoma. It induces tumor regression safely and efficiently by triggering DNA damage and activating the ROS/HIF‐1α/NF‐κB pathway, leading to caspase‐3‐mediated apoptosis.

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

Journal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.

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,

Laser‐Induced‐Structural Transformation in Ti3CNTx MXene Monitored by Raman Spectroscopy with DFT Insight

Small, EarlyView.
A multi‐wavelength Raman study of microwave‐assisted hydrothermal Ti3CNTx MXene, supported by theoretical calculations, identifies laser‐power thresholds and evaluates its ambient‐condition stability. ABSTRACT MXenes are emerging 2D nanomaterials that have attracted growing attention for their highly tunable atomic structure, composition, and surface ...

Nanoscale Mapping of Transition Metal Ordering in Individual LiNi0.5Mn1.5O4 Particles Using 4D‐STEM

Small Methods, EarlyView.
ABSTRACT The electrochemical performance of the spinel LiNi0.5Mn1.5O4, a high‐voltage positive electrode material for Li‐ion batteries (LIBs), is influenced by the transition metal arrangement in the octahedral network, leading to disordered (Fd3̲m$Fd\underline 3 m$ S.G.) and ordered (P4332 S.G.) structures.
