“…This may suggest that the small surface roughness in SiF 3 + -implanted samples is associated with the short projected ranges involved here. By using N + ion implant into W with different ion energies at different temperatures, Savaloni and Modiri [16] found a smaller surface roughness with a lower N + ion energy compared to that of a higher N + ion energy implant under identical implantation temperature. The results showed that implantation temperature plays an important role for the surface roughness.…”

“…They also speculate that the action of silver nanoparticles is broadly similar to that of silver ion. It may be anticipated that a bacterial cell in contact with silver nanoparticles takes in silver ions, which inhibit a respiratory enzyme(s), facilitating the generation of reactive oxygen species and consequently damaging the cell [62]. It is also demonstrated that the reactivity of silver is favored by high-atomdensity facets, such as {111} [15,65,66].…”

“…Crystallite size (coherently diffracting domains) D was obtained by applying the Scherrer formula [62] to measure the full width at half maximum (FWHM) of the dominant peak of silver nano-flower films [i.e., Ag(111)]. The results with 10 % accuracy are given in Table 1.…”

Silver chiral nano-flowers with 3-, 4-, and 5-fold symmetry were produced using oblique angle deposition method in conjunction with the rotation of sample holder with different speeds at different sectors of each revolution. X-ray diffraction, atomic force microscopy, and scanning electron microscopy were employed to obtain the nanostructure and morphology of the films. Their antibacterial, electrical, and hydrophobic properties were investigated. Antibacterial properties were investigated against a range of microorganisms including Escherichia coli ATCC 8739, Staphylococcus aureus ATCC 25923, and Candida albicans PTCC 5027. Electrical conductivity of these films relative to that of bulk sample is reduced by a factor of about 10 3 due to porosity, surface roughness, and anisotropic structure of these films. Hydrophobicity results show dependence on the symmetry of these chiral nano-flowers.

“…At room temperature of the sample, the sputtering prevails at kinetic energy up to a few keV and the implantation at larger energies like 25 keV, which is preferred in US2022154327 [ 33 ]. The penetration depth for 25 keV nitrogen ions is several 100 nm, and a gradual decrease in the N concentration in the metallic film is observed [ 36 ]. The annealing of implanted materials may change the distribution of implanted ions.…”

Bonded permanent NdFeB magnets are useful in numerous applications, including electric vehicles, and the demand is steadily increasing. A major drawback is corrosion due to inadequate wetting of the magnetic particles by liquid polymers such as polyphenylene sulfide or polyamide. Recently reported methods for corrosion inhibition are summarized, and their applicability is critically evaluated. The phosphorylation of magnetic particles inhibits corrosion but does not enable appropriate properties in harsh environments. The same applies to metallic coatings, which usually contain aluminum and zinc. Advanced epoxy adhesives are a promising solution, although some authors have reported inadequate corrosion resistance. The application of composite coatings seems like an appropriate solution, but the exact mechanisms are yet to be studied.
