ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A physics‐informed machine learning approach successfully decodes the complex catalytic activity of high‐entropy alloys for ammonia oxidation. By revealing a synergistic mechanism involving lattice and electronic couplings, the study identifies a superior “isolated‐surrounded” platinum motif.

The Hydrogenation of MNi3 Compounds (M = Si, Ge, Sn, Sb, Zr, V, Fe)
European Journal of Inorganic Chemistry, EarlyView.Hexagonal Ni3Sn takes up hydrogen to form α‐Ni3SnHx (filled Ni3Sn type, ΔV = 0.9%), followed by a transition to the cubic β‐Ni3SnHy (filled AuCu3 type, ΔV = 1.1% with respect to pristine Ni3Sn), while MNi3 (M = Zr, Si, Sb) compounds show no reaction toward hydrogen and MNi3 (M = V, Fe, Ge) compounds only a minute hydrogen uptake.

European Journal of Inorganic Chemistry, EarlyView.Using a multidentate ligand with two distinct coordination sites and a bridging coordination site, a series of novel linear pentanuclear complexes with alternately arranged 3d and 4f ions via a one‐pot reaction were synthesized. Cryomagnetic studies revealed the presence of intramolecular ferromagnetic interactions and their magnetic entropy changes ...

Materials and Corrosion, EarlyView.Excellent corrosion resistance of commercial Al‐containing materials is shown for exposures to liquid lead (Pb) at 600°C. However, oxide scale failure occurs at 700°C. The formed oxide scales and their failure mechanisms are explored. ABSTRACT Liquid lead (Pb) is an attractive heat transfer fluid for advanced thermal energy storage (TES) systems.

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel
Materials and Corrosion, EarlyView.Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...
