tio2 /fe3o4 nanocomposites with various tio2:fe3o4 ratios were synthesized by an ultrasonic-assisted deposition-precipitation method and their uv-light decolorization of congo dye and magnetic separation were investigated. the nanocomposite samples were characterized by scanning electron microscopy (sem), powder x-ray diffraction (xrd), surface area analayzer (bet) and fourier transform infrare...

environmental contamination, which is growing around the world, is a serious problem can not to be neglected. among all contaminations, water pollution is a major problem. azo dyes are one of the largest groups of pollutants found in the drinking water, coming from, and the food and textile industries. tio2/fe3o4 and tio2/fe2o3 nanocomposites with various ratios were synthesized by an ultrasoni...

Harnessing surface wrinkle surfaces in various functional devices has been a hot topic. However, rapidly creating wrinkled on elastomers of arbitrary shape (especially curved surfaces) is still great challenge. In this work, an ultrasonic-assisted deposition method proposed to achieve nanomodification the robust layer (e.g., carbon nanotubes (CNTs)) with labyrinth pattern polydimethylsiloxane (...

An ultrasound-assisted, precipitation-deposition method has been developed to synthesise visible-light-responsive BiOBr-ZnFe(2)O(4) heterojunction photocatalysts. The heterojunctions with suitable BiOBr/ZnFe(2)O(4) ratios have a fascinating micro-spherical morphology and exhibit exceptional photocatalytic activity in visible-light degradation of Rhodamine B.

In this paper we report on ZnS nanoparticles produced by precipitation of zinc acetate and sodium sulphide and stabilized by cetyltrimethylammonium bromide (CTAB) in aqueous media and deposited on montmorillonite (MMT). For the deposition a new method based on intensive cavitation was used. The montmorillonite carrier was first disintegrated by intense turbulent mixing in an ultrasonic field in...

Double-side replication of polymer substrates is beneficial to the design and the fabrication of 3-demensional devices. The ultrasonic embossing method is a promising, high efficiency and low cost replication method for thermoplastic substrates. It is convenient to apply silicon molds in ultrasonic embossing, because microstructures can be easily fabricated on silicon wafers with etching techni...

a new method for the synthesis of nano zero-valent iron (nzvi) was developed in the present study.ultrasonic waves, as a novel method, were used to synthesize the nanoparticles. the morphologyand surface compositions of the particles were characterized by using fesem, xrd, bet, andparticle size analyzer. the synthesized nanoparticles were then utilized as a fenton-like catalyst todegrade of hyd...
