Thermal and Mechanical Investigations of (Bi, Pb)-2212 Superconductor Added with Different Oxide Nanoparticles
The current study reports the synthesis of nano-(CdO)x/Bi1.6Pb0.4Sr1.9Ca1.1Cu2.1Oy, nano-(Cd0.95Mn0.05O)x/Bi1.6Pb0.4Sr1.9Ca1.1Cu2.1Oy, and nano (Cd0.95Fe0.05O)x/Bi1.6Pb0.4Sr1.9Ca1.1Cu2.1Oy composites, with x = 0.00, 0.01, 0.02, 0.05, and 0.10 wt. %, respectively, using the classical solid-state reaction technique. X-ray powder diffraction (XRD) confirmed the formation of an orthorhombic structure of the (Bi, Pb)-2212 as the major phase.
The investigation of the mechanical properties using Vicker’s microhardness measurements has revealed that CdFeO addition outperformed CdO and Manganese doped Cadmium Oxide (CdMnO) addition in improving the parameters of E, Y, K, and B, which display better ductility and an enhanced capacity to resist indentation fractures and facilitate (Bi-2212) manufactured in the form of round wires that can be used in high magnetic field magnets superconducting powerlines reducing the power transmission losses, and hence enhancement of the efficiency of green hydrogen production.

Enhancement of the physico-mechanical properties of La-doped Mg–Ni–Co tri-ferrites
This research explores how adding Lanthanum (La) affects tri magnesium-nickel-cobalt ferrites (Mg-Ni-Co ferrites). The physical properties of tri ferrites with different La concentrations were studied. The Structural characterization via XRD and TEM showed that La doping increased the crystal lattice size and decreased the size of individual crystals. The XPS measurements revealed the migration of Fe3+ ions from octahedral to tetrahedral sites matching with Mossbauer results. This caused an enhancement of the magnetic properties of the ferrites.
The investigation of elasticity moduli obtained from FTIR spectroscopy as well as Vickers microhardness measurements has shown an enhancement upon La doping elasticity and making them potentially useful for industrial applications.

The Potential of Hydrogen Transition for Ports in the Sultanate Oman
This exploratory document provides a comprehensive view of the advanced capabilities of our three deep-water ports of Duqm, Sohar and Salalah to achieve our decarbonization targets and act as forward logistical operating bases for worldwide clean energy transport. With their ideal locations, our ports are prime regional and global candidates to become vital hydrogen logistics hubs, and later fully fledged hydrogen valleys. In Oman, this outlook is the first publication released on hydrogen transition to signal the Sultanate’s readiness to kick off production initiatives and make a contribution to the world supply of renewable We showcase all the advantages Oman has to offer to become a vital presence in the new market and harness its geographic location, geopolitical advantages, and a recognized credibility.
