Abstract A key challenge in producing superhydrophobic coatings (SHC) is to tailor the surface morphology on micro-nanometer scale. In this work, a feasible and straightforward route was employed manufacture polystyrene/nickel oxide (PSN) nanocomposite aluminum alloys mitigate their corrosion saline environment. Different techniques were explore influence of addition NiO nanoparticles as-prepar...

A method is described to measure the refractive index dispersion with wavelength of optically trapped solid particles in air. Knowledge of the refraction properties of solid particles is critical for the study of aerosol; both in the laboratory and in the atmosphere for climate studies. Single micron-sized polystyrene beads were optically trapped in air using a vertically aligned counter-propag...

Background & Objectives: Nanotechnology is one of great important part of technology. Nanoparticles can be used in different applications for industrial, medical, military and personal use. The objectives of this study were preparation of Polystyrene/ZnO nanocomposite films via a simple method and investigation of antibacterial activity of them. Methods: Polystyrene /ZnO nanoparticle (PS/nano-...

In spite of the growing interest to exploit nanocellulose in membranes for water purification, reverse osmosis, packaging, and other applications, examples nanocellulose-containing pervaporation are rather limited. We here report preparation dense nanocomposite consisting a polystyrene-block-polybutadiene-block-polystyrene (SBS) matrix high-aspect-ratio cellulose nanofibers (CNFs). The were pro...

Maleimide-functionalized polystyrene (PSMA-SiO2/TiO2) hybrid nanocomposites were prepared by sol-gel reaction starting from tratraethoxysilane (TEOS) and titanium isopropoxide in the solution of polystyrene maleimide in 1,4-dioxane. The hybrid films were obtained by the hydrolysis and polycondensation of TEOS and titanium isopropoxide in maleimide-functionalized polystyrene solution followed by...

The development of synthetic bone graft substitutes is an intense area of research due to the complications associated with the harvest of autogenous bone and concerns about the supply of allogenic bone. Porous resorbable polymers have been used extensively in hard tissue engineering applications, but currently lack load-bearing capacity. Supercritical carbon dioxide (scCO(2)) processing is use...

PURPOSE With the wide recognition of oncostatic effect of melatonin, the current study proposes a potential breast cancer target multimodality treatment based on melatonin-loaded magnetic nanocomposite particles (Melatonin-MNPs). METHODS Melatonin-MNPs were fabricated by the single emulsion solvent extraction/evaporation method. RESULTS Based on the facilitated transport of melatonin by the...
