To investigate the initial morphological evolution of 321 stainless steel (SS) films, we examined the effect of sputtering time on the morphology of 321 SS film. In this study, a group of samples were prepared at nine different sputtering times within 20 s using radio-frequency (r.f.) magnetron...

In order to study the behavioral characteristics of the pore-scale hydrate formation, this experiment employs a high-pressure-resistant visible model in an etched glass plate to study the pore-scale methane hydrate formation and reveal its growth law s in porous media. The experiment shows that...

In the present work we consider the growth of a very dilute concentration of anisotropic particles, nucleated with random orientations, in a matrix of growing spherical particles. It is assumed that the matrix particles obey the usual JMAK kinetics. We concentrate on describing the change in...

We present a model equation that describes nucleation and growth of hemispherical nanoclusters or islands deposited on a substrate for the small surface coverage case. The model is formulated in terms of a set of rate equations for the island sizes, combined with the time-dependent behavior of...

Optical tweezers have recently been used to locally induce liquid–liquid phase separations and to nucleate a single domain inside the trap [H. Masuhara and co-workers, J. Phys. Chem. B 101 (1997) 5900; Langmuir 13 (1997) 414; Bull. Chem. Soc. Japan 69 (1996) 59]. We investigate theoretically these...

Titanium films of 120 nm thickness were magnetron sputtered on glass substrates at room temperature, and subsequently they were annealed under flowing oxygen atmosphere at different temperatures and time. Atomic force microscopy (AFM) was used to study topographic characteristics of the films,...

N-doped Cu2O films were deposited on quartz substrates by reactive magnetron sputtering a Cu2O target. The optical constants and thicknesses of the films with different nitrogen partial pressure (NPP) were retrieved from transmittance data by an optical model which combines the Forouhi–Bloomer...

CrCuN films were deposited under different substrate temperatures by direct current (DC) magnetron sputtering. The structure and wear resistance of the films were then studied. The substrate temperature has almost no effect on the film composition, phase constitution and preferred orientation....
