Transparent aluminum oxide nanostructures with extreme wetting properties were synthesized by nanosecond laser deposition in background oxygen. The transparency and morphology of the samples have been analyzed. Non-monotonic behavior transmittance coefficient was found when varying oxygen pressure range 20-140 Pa due to differences kinetics ablation product dispersion. evolution contact angle f...

Carbon nanomaterials are advantageous as electrodes for neurotransmitter detection, but the difficulty of nanomaterials deposition on electrode substrates limits the reproducibility and future applications. In this study, we used plasma enhanced chemical vapor deposition (PECVD) to directly grow a thin layer of carbon nanospikes (CNS) on cylindrical metal substrates. No catalyst is required and...

Irreversible adsorption of negatively charged polystyrene latex particles (averaged diameter 0.9 microm) at heterogeneous surfaces was studied experimentally. The substrate bearing a controlled number of adsorption sites was produced by precovering mica sheets by positively charged polystyrene latex (averaged diameter of 0.45 microm). Positive latex (site) deposition was carried out under diffu...

Because inhalation and intratracheal instillation deposit particles throughout the respiratory tract, these methods of administration give little information on the movement of particles within the lung and no direct information on the clearance kinetics from locally defined sites within alveolar tissue. Approximately 0.05 microL of 195Au-labeled gold colloid was administered to 32 rats by micr...

Kinetics of the deposition process of dimers in the presence of desorption is studied by Monte Carlo method on a one-dimensional lattice. The aim of this work is to investigate how do various temporal dependencies of the desorption rate hasten or slow down the deposition process. The growth of the coverage θ(t) above the jamming limit to its steady-state value θ(∞) is analyzed when the desorpti...

Polydopamine (PDA) coating provides a promising approach for immobilization of biomolecules onto almost all kinds of solid substrates. However, the deposition kinetics of PDA coating as a function of temperature and reaction method is not well elucidated. Since dopamine self-polymerization usually takes a long time, therefore, rapid-formation of PDA film becomes imperative for surface modificat...

Carboxylated, sulfated and/or phosphorylated surfaces are admitted as potential optimal templates for biomimetic deposition of calcium phosphate (CaP) coatings in view of improving implants' osseointegration. Layer-by-layer films were built up consisting of anionic chondroitin sulfate (ChS), a biological carboxylated and sulfated polysaccharide and cationic poly(l-lysine) (PLL). The films were ...

The type of solid substrate plays a critical role in determining the kinetics spray fluidized bed (SFB) agglomeration process. In case porous (also soft) primary particles (PPs), droplet aging is due to imbibition and drying. surface properties also change imbibition. focus present work simulate spray-dried milk powder using Monte Carlo (MC) method coupled with drying-imbibition model. order ex...
