Mechanical Alloying Integrated with Cold Spray Coating for Fabrication Cu(TiNi), x; 10, 20, 30, and 40 at.% Antibiofilm Metallic Glass Coated/SUS304 Sheets.

Antibacterial agents derived from conventional organic compounds have traditionally been employed as a biofilm protective coating for many years. These agents, on the other hand, often include toxic components that are potentially hazardous to humans. Multiple approaches have been investigated over the last two decades, including the use of various metallic and oxide materials, in order to produce a diverse variety of usable coating layers.

Effect of ZrC Nanopowders on Enhancing the Hydro/Dehydrogenation Kinetics of MgH Powders.

Hydrogen has been receiving great attention as an energy carrier for potential green energy applications. Hydrogen storage is one of the most crucial factors controlling the hydrogen economy and its future applications. Amongst the several options of hydrogen storage, light metal hydrides, particularly nanocrystalline magnesium hydride (MgH), possess attractive properties, making them desired hydrogen storage materials.

Mechanically-Induced Solid-State Reaction for Fabrication of Soft Magnetic (CoTi)B (x: 2, 5, 10, 15, 20, 25 at%) Metallic Glassy Nanopowders.

Metallic glasses, with their short-range order structure, exhibit unique characteristics that do not exist in the corresponding crystalline alloys with the same compositions. These unusual properties are attributed to the absence of translational periodicity, grain boundaries, and compositional homogeneity. Cobalt (Co)-based metallic glassy alloys have been receiving great attention due to their superior mechanical and magnetic properties.

Solid-State Conversion of Magnesium Waste to Advanced Hydrogen-Storage Nanopowder Particles.

Recycling of metallic solid-waste (SW) components has recently become one of the most attractive topics for scientific research and applications on a global scale. A considerable number of applications are proposed for utilizing metallic SW products in different applications. Utilization of SW magnesium (Mg) metal for tailoring high-hydrogen storage capacity nanoparticles has never been reported as yet.

Glass-Forming Ability and Soft Magnetic Properties of (CoTi)Fe (x; 0-20 at.%) Systems Fabricated by SPS of Mechanically Alloyed Nanopowders.

Due to their outstanding mechanical properties and soft magnetic characteristics, cobalt-based metallic glassy alloys have stimulated much interesting research. These metastable ferromagnetic materials possess very small magnetocrystalline anisotropy, and almost zero magnetostriction. They reveal low coercivity, extremely low core loss, moderate saturation polarization, and very high magnetism.

Recent developments in the fabrication, characterization and implementation of MgH-based solid-hydrogen materials in the Kuwait Institute for Scientific Research.

Hydrogen energy holds tremendous promise as a new clean energy option. It is a convenient, safe, versatile fuel source that can be easily converted to the desired form of energy without releasing harmful emissions. Hydrogen storage, which spans both hydrogen production and hydrogen applications, plays a critical role in initiating a hydrogen economy.

Metallic glassy TiNi grain-growth inhibitor powder for enhancing the hydrogenation/dehydrogenation kinetics of MgH.

Because of its high thermal stability and poor hydrogenation/dehydrogenation kinetics, magnesium hydride (MgH) requires mechanical treatment and/or doping with catalytic agents(s) to understand the decomposition temperature and accelerate the gas uptake/release kinetics. Whereas all catalytic species used for this purpose are crystalline materials, in this paper use of titanium nickel (TiNi) metallic glassy (MG) nanopowders for enhancing the hydrogenation/dehydrogenation kinetics behavior of MgH powders is reported. In the present research, MG-TiNi ribbons, prepared using a melt spinning technique were snipped into small pieces and then cryo-milled under a flow of liquid nitrogen to obtain submicron-powders (500 nm).

Performance and fuel cell applications of reacted ball-milled MgH/5.3 wt% TiH nanocomposite powders.

The present study aimed to enhance the kinetics behavior and destabilize the thermal stability of MgH powder by high-energy milling of Mg powder under 50 bar of H for several hours using Ti-balls as the milling media. The results showed a monotonical increase in Ti content worn off the milling media and introduced into the milled powders. This gradual doping led to homogeneous distribution of fine Ti particles into the Mg/MgH powder matrix without agglomeration or compositional fluctuations at the micro-level.

Discovering a new MgH metastable phase.

Formation of a new metastable fcc-MgH nanocrystalline phase upon mechanically-induced plastic deformation of MgH powders is reported. Our results have shown that cold rolling of mechanically reacted MgH powders for 200 passes introduced severe plastic deformation of the powders and led to formation of micro-lathes consisting of γ- and β-MgH phases. The cold rolled powders were subjected to different types of defects, exemplified by dislocations, stacking faults, and twinning upon high-energy ball milling.
