Ultra‐High Temperature Calcination of Crystalline α‐Fe2O3 and Its Nonlinear Optical Properties for Ultrafast Photonics

Advanced Science, EarlyView.
This study focuses on exploring the nonlinear optical properties of α‐Fe2O3 material calcined at ultra‐high temperatures. It is discovered that the α‐Fe2O3 material underwent the phase transition at ultra‐high temperatures. Then, the α‐Fe2O3 material calcined at 1100 °C is successfully integrated as a saturable absorber into an erbium‐doped fiber laser,

A Bifunctional Fibrous Scaffold Implanted with Amorphous Co2P as both Cathodic and Anodic Stabilizer for High‐Performance Li─S Batteries

Advanced Science, EarlyView.
An amorphous Co2P‐embedded porous carbon nanofiber membrane (A─Co2P/PCNF) via electrospinning/in situ phosphorization is developed to serve as the dual‐electrode stabilizer for Li─S batteries. The amorphization strategy enables more exposed undercoordinated Co sites with optimized d‐band centers, enhanced LiPSs adsorption/catalysis, and lithiophilicity‐

Rough and Tough: How Particle Surface Roughness Affects Liquid Marble Formation and Stability

Advanced Science, EarlyView.
This study investigates the influence of particle surface roughness on the formation and stability of liquid marbles using well‐defined colloidal supraparticles as model systems. Increasing surface roughness enhances the interfacial contact angle, improves mechanical stability by increasing deformation resistance upon impact, and enables liquid marble ...

Laser‐Induced Co‐Doped FePS3 with Massively Phosphorus Sulfur Vacancies Nanosheet for Efficient and Highly Stable Electrocatalytic Oxygen Reaction

Advanced Science, EarlyView.
DFT‐guided defect engineering in 2D FePS3 reveals S/P vacancies Co‐doped and exposed Fe sites synergistically enhance OER performance. Laser‐ablation‐induced (Fe0.53Co0.46)PS3 exhibits excellent OER performance (288 mV overpotential, 58.3 mV dec−1 Tafel slope) and outstanding stability (138 h at 10 mA cm−2, 27h at 100 mA cm−2).

Unlocking Modulation Rule of Heterointerface Engineering Induced D‐Band Center on Polysulfides Conversion in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
The homologous heterostructure of ZIF‐67‐derived CoSe2@CoSe0.25S1.75 with a behavior of semi‐coherent phase boundary is constructed to modulate the d‐band center (εd) of Co, which can be a significant descriptor for Li+ storage of S cathode. It is revealed that the adsorption and conversion ability to LiPSs and the discharge‐specific capacity describe ...

Twin Toughening‐Driven Martensitic Transformation Strategy Synergistic Improvement for Plasticity‐Thermal Shock Resistance of (Hf─Zr─Ti)C Ceramic Coating in Severe Thermal Environments

Advanced Science, EarlyView.
A “ceramic self‐toughening strategy” is introduced for enhancing the plasticity and thermal shock resistance of (Hf─Zr─Ti)C coatings through twin toughening‐driven martensitic transformations in oxide scales. It facilitated the formation of stable, dense, and high‐toughness oxide scales after repeat ablation, and endowed prepared coatings with superior

Packaging Metal Atomic Clusters for Universal and Robust Protection through Cluster Beam Process

Advanced Science, EarlyView.
Gas‐phase‐aggregated metal clusters are packaged and well‐protected in poly(methyl methacrylate) (PMMA) through controlled beam implantation. The packaged precise clusters show robust protection against oxidation and agglomeration. This protection also demonstrates universality, as it successfully protects metal clusters composed of various elements ...
