Mechanistic CFD-Guided Design of Nanocomposite Multilayer Coatings: Adaptive Hot Corrosion Control in Sulphur Recovery Unit Carbon Steel Piping

This study demonstrates that integrating computational fluid dynamics with electrochemical modeling to design nanocomposite multilayer coatings effectively mitigates hot corrosion in sulphur recovery unit carbon steel piping, reducing corrosion rates by orders of magnitude while maintaining stable flow dynamics across varying operating temperatures.

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.

Significant effect of neodymium oxide (Nd2O3) into mechanical and structural characteristics of lithium borate glass systems for superior radiation-shielding performance

This study demonstrates that substituting Na₂O with Nd₂O₃ in lithium borate glass systems enhances structural integrity, mechanical properties, and gamma-ray shielding performance by increasing density, converting BO₃ to BO₄ units, and strengthening ionic interactions, with the 4 mol% Nd₂O₃ composition exhibiting optimal radiation protection capabilities.

Identifying Hidden Trends in Complex Data to Design Best Metal-Organic-Framework Catalysts for Oxygen Evolution Reaction

This study introduces a "hidden trend mining" workflow that integrates machine learning with subgroup discovery to identify local structure-activity relationships in bimetallic thiophene-2,5-dicarboxylate metal-organic frameworks, successfully predicting and experimentally validating a highly efficient NiFe catalyst for the oxygen evolution reaction with an overpotential of 186 mV.

Effective Catalytic Esterification of Fat-Oil-Grease into Biodiesel over Sulfonated Zinc-Carbon Catalysts

This study demonstrates that a sulfonated zinc-carbon catalyst (ACZnS-220-5wt%), synthesized from sunflower husk via hydrothermal treatment and sulfonation, effectively converts waste fat-oil-grease into biodiesel with an 88% yield and stable reusability over five cycles due to its high surface area and strong Zn-S acid sites.

Pressure-Controlled Activity and Selectivity in Superbase-Catalyzed O-Vinylation of Menthol and Thymol with Acetylene

This study demonstrates that the KOH–DMSO superbase-catalyzed O-vinylation of menthol and thymol with acetylene exhibits distinct pressure-dependent activity and selectivity profiles, where optimal yields are achieved within specific pressure windows (12 atm for menthol and 14 atm for thymol) before secondary reactions degrade performance at higher pressures.
