phenolic resins have been widely used for selective high technology applications due to their excellent ablative properties, structural integrity and thermal stability that make them appropriate for thermal insulation materials, wood products industry, coatings, moulding compounds and composite materials. polymer layered silicate nanocomposites based on montmorillonite (mmt) have attracted a gr...

Ultrasonic processing in the cavitation mode is used to produce composite materials based on metal matrix and reinforcing particles of micro- nano-sizes. In such a case, deagglomeration aggregates uniform distribution are expected effects. Although can not only fragment acoustic field, they also coagulate, coarsen precipitate. this paper, theoretical study processes coagulation liquid under ult...

Influence of different types surfactants on electrodeposition copper- and carbon-bearing (graphite, carbon nanotubes (CNTs)) composite powder has been experimentally investigated. The size particles decreased, corrosion resistance increased when were added. Addition cationic surfactant CTAB to the electrolyte with simultaneous ultrasonic treatment for CNTs dispersion gives maximum effect.

Surface wave dispersion measurements can be used to nondestructively characterize shot-peened, laser shock-peened, burnished, and otherwise surface-treated specimens. In recent years, there have been numerous efforts to separate the contribution of surface roughness from those of near-surface material variations, such as residual stress, texture, and increased dislocation density. As the accura...

Nano-ZnO was prepared by direct precipitation method with zinc chloride and sodium carbonate anhydrous as raw materials, and its particle size and dispersion were characterized by TEM. The effects of concentration and the ratio of reactants and reaction temperature on its dispersion in aqueous solution were analyzed and the best reaction conditions were as follows: reaction temperature 60 , ult...

The interaction of nanomaterials with biological macromolecules is an important foundation of the design and the biological safety assessments of nanomaterials. This work aims to investigate the interaction between pristine C60 and serum albumins (human serum albumin and bovine serum albumin) in solution. Stable aqueous dispersion of C60 was prepared by simple direct ultrasonic method and chara...
