National Science Review

The formation of a strong coordination structure, [Zn(H2O)6]2+ often increases direct contact between the solvated H2O and Zn anodes on the inner Helmholtz layer, which exacerbates undesirable side reactions and dendrite growth, hindering the practical application of aqueous Zn metal batteries. Here, we identify that the solvated H2O can be effectively minimized by an artificial solid electrolyte interphase (SEI) consisting of highly nitrogen-doped amorphous carbon (NC) and perfluorosulfonic acid polymer (Nafion). Theoretical and experimental analyses reveal that NC raises the Fermi level of the composite SEI and activates the non-coordinating charge transfer from the SEI to [Zn(H2O)6]2+, which leads to ultrafast desolvation of hydrated Zn-ions in the outer Helmholtz layer; while the Nafion framework ensures selective transport channels for Zn ions. Remarkably, the derived NC-Nafion@Zn symmetric cell exhibits a long lifespan (3400 h, 1 mA cm–2; 2000 h, 5 mA cm–2); moreover, the NC-Nafion@Zn//Mn4O3-carbon nanotubes full battery delivers ultralong cycling stability of 9300 cycles at 2 A g–1 with a high retention of 91.3%.

The Innovation Geoscience

The Late Ordovician mass extinction (LOME, ca. 445 Ma), which occurred over two extinction intervals (LOMEI-1 and LOMEI-2), was the first “Big Five” biotic crises of the Phanerozoic. The ultimate trigger of this extinction remains debated, with glacially induced global cooling and volcanism-driven warming events separately suggested as the underlying cause. Here, we report anomalously high mercury (Hg) levels in two Ordovician-Silurian successions from a shelf-to-slope transect in South China, indicating abnormally high Hg loading to the ocean. Analyses of Hg isotopes through the successions reveal near-zero Δ¹⁹⁹Hg from the late Katian to the earliest Hirnantian (LOMEI-1), suggesting that Hg was mainly derived from large-scale volcanism. Positive shifts in Δ¹⁹⁹Hg are observed during the Hirnantian stage, coincident with global glaciation, suggesting enhanced Hg sequestration to sediments driven by subsidence of cold and dense surface seawater. Negative shifts in Δ¹⁹⁹Hg values across the LOMEI-2 within the Hirnantian likely suggest enhanced terrestrial Hg and sulfate fluxes to the ocean due to volcanism-induced global warming, which promoted oceanic anoxic/euxinic conditions. This study provides novel evidences linking intensive volcanism to significant changes in the atmosphere-land-ocean system across the Ordovician-Silurian transition, particularly to the euxinic ocean conditions that triggered the LOME.

Developing a robust zinc (Zn) anode, free from Zn dendrites and unwanted side reactions, relies on designing a durable and efficient interfacial protection layer. In this study, gradient coating technology is employed to construct a hierarchically structured composite of Sn with diamond‐like carbon (DLC/Sn‐DLC) as an artificial protective layer. The DLC framework endows DLC/Sn‐DLC layer with high stability and adaptability, achieving long‐term stability of the anode–electrolyte interface. The gradual‐composite Sn, with its Sn─O─C interface chemical bonds, facilitates rapid charge transfer and offers ample zincophilic sites at the base, promoting uniform Zn²⁺ reduction reaction and deposition. Additionally, the DLC/Sn‐DLC composite exhibits a “lotus effect” and favorable hydrophobic properties, preventing water‐reduced side reactions. Leveraging this structural design and the synergistic cooperation of DLC and Sn, the DLC/Sn‐DLC@Zn electrode demonstrates remarkable Zn plating/stripping reversibility, eliminating Zn dendrites and side reactions. Notably, under a high current density of 10 mA cm⁻², the DLC/Sn‐DLC@Zn anode‐based symmetrical cell exhibits stable operation for over 1550 h, with a low nucleation overpotential of 101 mV. The DLC/Sn‐DLC@Zn||Mn3O4‐CNTs full battery delivers a high capacity of 109.8 mAh cm⁻² after 5800 cycles at 2 A g⁻¹, and the pouch cell shows potential for energy storage applications.

During the early stage, the formation is water-saturated with favorable porosity and permeability (Begum et al., 2019;Gholinezhadateni and Rostami, 2021), also facilitating the migration and accumulation of early-generated molecules with long side chains and low aromaticity. After noise elimination and intensity normalization of the non-hydrocarbon data, compositional similarities among samples can be quantified using cosine distance (Yuan et al., 2024). Taking interlayer siltstones as benchmarks, the shales with high compositional similarities indicate "sweet spots", since they might have undergone similar compositional fractionation. ...
