Pyrolysis temperature-driven radical-to-nonradical pathway transition in Fe0/biochar activated peroxymonosulfate: Structural evolution and mechanistic insights

This study demonstrates that pyrolyzing iron-loaded peanut shell biochar at 800°C induces a structural transformation from iron oxides to zero-valent iron and graphitic carbon, which drives a decisive shift from a radical-dominated to a singlet oxygen-mediated non-radical pathway for efficient peroxymonosulfate activation and pollutant degradation.

Synthesis and Structural Characterisation of (E)-N-(3,4,5-Trimethoxybenzylidene)aniline

The parent Schiff base (E)-N-(3,4,5-trimethoxybenzylidene)aniline was synthesized via microwave condensation and structurally characterized by spectroscopy and single-crystal X-ray diffraction, revealing a centrosymmetric P21/n crystal structure that differs from its non-centrosymmetric halogenated analogues while providing a crucial halogen-free reference for tubulin-polymerisation-inhibitor-related compounds.

Isosteric Cl↔CH 3 Substitution in Cyclometallated Pt(II) Thiocyanate–Isocyanide Complexes: Polymorphism, Solvatomorphism and Supramolecular Organisation 1

Two new cyclometallated platinum(II) complexes featuring an isothiocyanato ligand and an arylisocyanide were synthesized and characterized, revealing that an isosteric Cl↔CH₃ substitution is crystallochemically silent in isostructural polymorphs while dynamic N/S linkage equilibria and diverse supramolecular architectures involving Pt···Pt contacts dictate their solid-state organization and room-temperature luminescence.

Effect of β precipitate size on the short-term high temperature oxidation resistance in γ-β two phase alloy

This study demonstrates that the size of β precipitates in a γ-β two-phase Ni-based alloy critically governs its short-term high-temperature oxidation resistance at 1000°C by controlling the local supply of aluminum and chromium, which in turn determines the resulting oxide scale structure and mass gain.

Investigation on interfacial behavior and fracture characteristics of MarM247/Hastelloy X joints brazed with BNi-2 filler

This study systematically investigates the vacuum brazing of Mar-M247 and Hastelloy X superalloys using BNi-2 filler, revealing that optimal shear strength of 257.05 MPa is achieved at 1150 °C for 10 min, where microstructural homogenization and a shift in fracture mechanism from brittle to mixed-mode failure occur.
