Long‐Term Corrosion of Carbon‐Steel Casing Used in Deep Geological Radioactive Waste Repository

Materials and Corrosion, EarlyView.
Fifty mots 6‐year study of carbon steel corrosion in a deep geological repository (Bure, France). Three corrosion patterns were identified, driven by local conditions. Minimal corrosion layer thickness growth suggests limited corrosion progression under most conditions.

Regulation mechanism and kinetic characteristics of pyrite oxidation mediated by aluminum-bearing minerals

Chemical Engineering Journal Advances
As the most prevalent metal sulfide mineral in mining environments, pyrite readily undergoes oxidation under surface conditions to generate acid mine drainage, resulting in a series of environmental pollution issues.

Rational Design Strategies Toward Efficient and Stable Electrocatalysts for Hydrogen Production via Water Electrolysis: A Comprehensive Review

Small, EarlyView.
ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...

Sodium‐Based Battery Component Design: Imitating Lithium or Forging New Paths?

Small, EarlyView.
This Perspective elucidates the decisive yet underexplored impact of cation chemistry, Na+ vs. Li+ charge carriers, on the design, selection, and formulation of their corresponding battery systems, addressing common misconceptions and the pitfalls of overreliance on Li+ design principles. Leveraging the unique characteristics of Na+, it comprehensively

NaCl‐Templated Iron Sulfide/N‐Doped Carbon Microspheres for High‐Performance Sodium‐Ion Batteries: From Nanostructural Design to Pouch Cells

Small, EarlyView.
NaCl‐templated FeS microspheres with a conformal N‐doped carbon coating are synthesized via scalable spray pyrolysis and subsequent surface engineering. The interconnected porous framework accelerates Na+ transport and alleviates structural degradation during cycling. Benefiting from enhanced electrochemical kinetics and mechanical robustness, FeS‐NaCl@

A century of structures: historical fidelity and computational fitness in the Inorganic Crystal Structure Database (ICSD)

Acta Crystallographica Section B, EarlyView.
Of 464 Inorganic Crystal Structure Database (ICSD) structures from 1913 to 1929, the vast majority are structurally sound, but a small number carry genuine topological errors whose corrective information exists in the database yet is invisible to automated queries.
