Fluorocarbon thin-film deposition is studied, which shows an anomalous high dynamic growth exponent and therefore does not fit in any universal class of fractal surface growth models. A detailed analysis of the nonlinear behavior of the surface morphology evolution is carried out, quantifying several features of the shadowing instability. A synergy effect with the Kardar-Parisi-Zhang nonlineari...

Plankton autotrophs vary greatly in size and shape. Computation of surface/volume ratios for biomass units of 27 coexisting phytoplankton species in a tropical lake indicates that these ratios are conserved within a range much narrower than expected by random choice of shapes. Conservation of surface/volume ratios suggests new explanations for the shapes of phytoplankton biomass units.

Direct comparison is made of the steady-sates and coarsening dynamics in a local system and its nonlocal generalization. The example system is the surface of a solid film in a strong electric field; the morphological evolution of the surface is described, in the long-wavelength approximation, by the amplitude PDE for the film height function. It is shown that the amplitude of the steady-state a...

We study the variation of sputtering yields with surface morphologies under the assumption of a specially prescribed surface shape. Compared with a flat surface, we show that surface morphology can cause a decrease in the sputtering yield and an increase in the incident angle where sputtering yield is maximum. Based on Sigmund’s theory, an analytical formula for the morphology dependent sputter...

The joint surfaces of 60 hips obtained from the cadavers of elderly Asians were studied to determine the incidence, the grade and the distribution of both non-progressive (age-related) and progressive degenerative changes. It was observed that in the Asian population of 40 to 90 years of age, non-progressive changes were common, being seen in 66% of the acetabular specimens and 50% of the femor...

synthesis, identification and thermal behavior studies of nanoparticles cobalt (ii) bromide has been studied in this research. cobalt (ii) bromide was synthesized by planetary high-energy ball mill. the general formula of this compound is cobr2.6h2o. the synthesized nanoparticles were characterized by fourier transform infrared spectroscopy and also size and structure of synthesized nanoparticl...

The purpose of this study was to produce oil in water Nano-emulsion by ultrasonication, and investigate the influence of Inulin and β-cyclodextrin on the prosperities of Nano-emulsion and morphology of spray dried microcapsules. The results showed that emulsion droplet size in samples containing β-cyclodextrin (8.28±0.11 nm) was less than Inulin samples (97.12±4.2 nm). Considering SEM photos, β...
