A new study published in Science China Earth Sciences presents a comprehensive plan for scientific ocean drilling in the Huatung Basin, a key region in the western Pacific. Researchers propose a four-site drilling strategy for China’s new drilling vessel, Mengxiang, to resolve long-standing debates about the basin's age and the origin of the adjacent Gagua Ridge. The plan aims to determine if the Huatung Basin is a remnant of Mesozoic oceanic crust and to clarify the region's tectonic evolution, marking a potential shift for China’s role in leading international ocean drilling.

Using a highly sensitive two-coil mutual-inductance technique, we systematically track the evolution of the phase stiffness in interfacial superconducting LaAlO₃/KTaO₃(111) and its correlation with the superconducting transition temperature as a function of electrostatic gating. A crossover from Bose–Einstein-condensate-like to Bardeen–Cooper–Schrieffer-like behavior is revealed, suggesting that superconductivity at the two extremes is limited by the establishment of phase coherence and the formation of Cooper pairs, respectively. This behavior is consistent with the emergence of superconducting granularity in two dimensions, which is further supported by the observation of a paramagnetic Meissner effect.

Seawater zinc-air batteries (SZAB) could provide safe, high-energy power for marine applications, but Cl⁻ in seawater can poison the catalysts that drive oxygen reduction reaction (ORR). Researchers from Hainan University and collaborators designed an FeSn dual-single-atom catalysts (FeSn-DSACs) in which Sn neighbors tune Fe active sites through p-d orbital hybridization. The catalyst simultaneously accelerates ORR and suppresses Cl⁻ adsorption and corrosion. In SZAB, it delivered a peak power density of 255.6 mW cm⁻² and operated for more than 500 h, offering a design strategy for durable seawater ORR catalysis.

A data-knowledge dual-driven machine-intelligence framework enables experiment-efficient, full-chain synthesis of 2D dendrites. It achieves rapid process optimization within one week, constructs high-fidelity recipe-morphology mappings, and deciphers multifactorial growth mechanisms, requiring <70 experiments, which covers <1.5% of the total parameter combinations.

Researchers have developed a strategy to improve the fire safety of polymer materials by using ZIF-67, a porous metal-organic framework, together with different flame-retardant components. The study explains how ZIF-67 can enhance fire resistance, reduce smoke release and provide a versatile platform for designing safer high-performance polymer composites.

Molecular perovskite energetic materials (PEMs), featuring ordered ABX₃ crystal frameworks, have emerged as a promising platform for integrating fuel and oxidizing components at the molecular and crystal levels. A review in Energetic Materials Frontiers establishes molecular perovskites as a distinctive platform for the development of multicomponent energetic crystals. Their modular crystal architecture enables fuel and oxidizer components to be organized within ordered lattices, while site substitution, composite modification and data-driven design provide multiple pathways for tuning energy release, thermal stability and safety.
