The effects of intermixing on strained heteroepitaxial growth are studied with kinetic Monte Carlo. A solid-on-solid bond counting formulation with a ball and spring model for elasticity is used. Significant intermixing of the film with the substrate due to kinetic roughening of the film and hence the dilution of the film, is observed. This dilution is found to have a stabilizing role in the su...

Unravelling synthesis-morphology-performance relations of thin-film polyamide (PA) selective layers prepared via interfacial polymerization (IP) is essential for tailor-made membrane design. Here, an approach outlined, which links synthesis and morphology in terms the stability a system undergoing IP, with notion that transition from stable to unstable state corresponds morphological shift resu...

Corrosion behavior of mild steel in chloride contaminated alkaline solution has been studied for the period up to 100days. Saturated Calcium hydroxide solution was used as alkaline solution and 0.5M NaCl solution was used to accelerate mild steel corrosion. The Charge transfer resistance Rct, Current density Icorr and inhibition efficiency values were obtained from tafel polarization and electr...

the manner of spray the fuel has an important effect on stability and convenient mixture of fuel and oxidizer. swirl injectors because of formation of uniform spray cone and proper distribution of the fuel have been used in many rocket engines at aerospace industries. formation and development of air core in the interior stream of swirl injectors and simulation of them is complicated. double ba...

We demonstrate that silver nanoisland film self-assembled on the surface of silver-containing glass in the course of thermal processing in hydrogen is capable to detect 10-7 M concentration of rhodamine 6G in water using surface enhanced Raman spectroscopy (SERS) technique. The film can be multiply restored on the same glass substrate via annealing of the glass in hydrogen. We showed that the f...

Compared to the long history of plasmonic gratings, there are only a few studies regarding the bandgap in the propagation of plasmonic surface waves. Considering the previous studies on interpretation of plasmonic bandgap formation, we discuss this phenomenon using the effect of both surface plasmon polariton (SPP) and localized surface plasmon (LSP) for our fabricated one-dimensional metallic-...

Human antibody response to the Anopheles gambiae salivary protein gSG6 has recently emerged as a potentially useful tool for malaria epidemiological studies and for the evaluation of vector control interventions. However, the current understanding of the host immune response to mosquito salivary proteins and of the possible crosstalk with early response to Plasmodium parasites is still very lim...

Pd particles supported on SnO2 and GeO2 have been structurally investigated by X-ray diffraction, (High-Resolution) transmission and scanning electron microscopy after different reductive treatments to monitor the eventual formation of bimetallic phases and catalytically tested in methanol dehydrogenation/reforming. For both oxides this included a thin film sample with well-defined Pd particles...

Irrespective of thin film preparation methods such as PVD and CVD, the thin film process comprises three elementary stages including decomposition, transport, and nucleation and growth mechanisms. Fig. 1 shows the flow chart of the thin film process, where starting materials are successively modified to the resulting films. In the first stage, starting materials in the form of gas, liquid or so...

This paper reports a fundamental study of lubricant film formation with model synovial fluid components (proteins) and bovine serum (BS). The objective was to investigate the role of proteins in the lubrication process. Film thickness was measured by optical interferometry in a ball-on-disc device (mean speed range of 2-60 mm/s). A commercial cobalt-chromium (CoCrMo) metal femoral head was used...
