The Influence of Ni Content in NixCoy‐BDC Metal‐Organic Frameworks on Catalytic Activity for Hydrogen Generation from Sodium Borohydride

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
ABSTRACT Mono‐ and bimetallic Ni/Co‐based metal–organic frameworks (MOFs) coordinated with 1,4‐benzenedicarboxylate were successfully synthesized via a solvothermal approach and characterized by PXRD, FTIR, TGA, SEM–EDS, TEM, BET, and XPS. Fine control over the Ni:Co molar ratio enabled systematic modulation of the structural and electronic properties ...

Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

X-Ray Spectrometry, Volume 55, Issue 3, Page 443-453, May/June 2026.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.
