The nucleation and growth of Cu2O and NiO islands due to oxidation of CuxNi1–x(001) films were monitored, at various temperatures, by in situ ultra-high vacuum (UHV) transmission electron microscopy (TEM) and in situ synchrotron X-ray diffraction (

For basic understanding of how to produce a homogeneous distribution of nano-scale oxide particles, we have applied dual ion-implantation to make a super-saturation of oxide-forming elements. Y+ and O+ ions were implanted into ferritic alloys at room

Characterization of structure and mechanical properties of Ti–Si–N coatings deposited by a high-density plasma assisted vapor deposition technique at ∼250 °C was carried out and compared to Ti–Si–N coatings deposited at ∼700 °C. The nan

Several previous studies have shown that the size distributions of smaller nanoparticles (n⩽40 where n is the number of atoms in a given cluster) generated by ion sputtering obey an inverse power law, with an exponent varying between −8 and −4,

Starting from two-step anodizing recipes available in the literature, we fabricated self-supporting ordered ion-implantation masks that are several mm2 in area and approximately 2 μm thick. SEM micrographs reveal self-organized structures with strai

We have synthesized a series of Ti–Si–N coatings with 0–20 at.% Si by high-density plasma-assisted vapor phase deposition. Composition, structure and atomic short-range order were characterized by Rutherford backscattering spectrometry (RBS), t

A series of Ti–Si–N coatings with 0 < Si < 20 at.% were synthesized by inductively coupled plasma assisted vapor deposition. Coating composition, structure, atomic short-range order, and mechanical response were characterized by Rutherford backsc

Specimens of glassy Pd80Si20 were irradiated at temperatures below 100 K with 3.5MeV krypton ions. After irradiation, changes in the sound velocity were measured at 80 K without warm-up by Brillouin scattering. The sound velocity decreased with incre

We report on the characterization of microstructure and mechanical properties of sputter deposited Ti-containing amorphous carbon (Ti-aC) coatings as a function of Ti composition. Ti-aC coatings have been deposited by unbalanced magnetron sputter dep
