MOFs are one large group of complex organometallic compounds that build structured networks, have a high surface area, and a very large volume of pores.
This condition is indeed very reasonable because MOFs are compounds that are very flexible and can be engineered in an effort to adjust to the purpose of their application [9].
One group of MOFs that has been widely known is zeolitic-imidazolate frameworks (ZIFs), MOFs that adopt a zeolite topology with imidazole compounds as ligands that also function as linkers [10].
Recently, Mathur et al. conducted research on coating LiFePO4 with ZIF-8, which is mechanofusion-assisted by multi-walled carbon nanotubes, with the aim of high-rate performance and discharge capacity improvement [21].

The origin of low coercivity in amorphous alloys can be attributed to non-existence of magnetocrystalline anisotropy.
The origin of low coercivity in nanocrystalline soft magnetic alloys can be attributed to the proximity to the superparamagnetic limit.
Besides, the Micromagnetic model supposes only nearest-neighbor coupling, and this is unrealistic especially for rare-earth compounds, where RKKY long range interactions take place [34].
Summary and Conclusions As mentioned in the introduction, this discussion excludes amorphous and nanocrystalline alloys near the superparamagnetic limit.

Introduction
The uses of magnesium and its alloys are increased rapidly [1], and this trend is expected to be
continuous in the future.
Magnesium has the lowest density in the commercial alloys [2] and its alloys offer good castability, specific strength, stiffness, welding/machining ability, and relatively good shielding capability against electromagnetic interference, etc.
All these characteristics make magnesium alloys particularly attractive for the use of structural materials for electronics, telecommunications, and transportation applications.
In the casting process of magnesium alloys, the generation of considerable quantities of return scrap such as runners, overflow, flash, rejects etc. is not avoidable [3].
However, it is expected that nitrogen and oxygen form solid compounds with magnesium vapor and do not concern the pressure in the reactor [7], because they have a great affinity for magnesium.

A Cu-free alloy 6082 is compared with Cu-containing alloys 6013 and 6111.
The effects of Mg:Si ratio of the alloys are also quantified by means of a comparison between alloys 6111 and 6013.
These alloys contain a phase named Q, which is a quaternary compound with various reported stoichiometry [2].
Experimental The alloys were prepared by melting together the pure elements in a resistance furnace with the aim to achieve similar total (Mg + Si) contents in the different alloys (Table 1).

Corrosion management can include use of paints and sealants and, increasingly, the application of Corrosion Inhibiting Compounds (CICs) which retard corrosion, by penetrating into crevices and cracks, and displacing water.
Structural impact of corrosion inhibitors The first issue relates to the use of Corrosion Inhibiting Compounds (CICs) - chemicals which can be painted or sprayed onto structure and which retard or inhibit the development of corrosion.
The specimens were single lap joints made from 2024-T3 Aluminium alloy 1 mm thick, with two rows of dome-head MS20470AD4-4 (2117-T4 Aluminium alloy) rivets with a shank diameter of 3.175 mm.
Effect of penetrant on fatigue of aluminium alloy lap joints.
