Abstract This work aimed at treating OMW by developing an environmentally friendly and cost-effective media capable of removing phenolic compounds upon the interaction between magnetic nanoparticles sorbent material such as zeolite. Magnetite (Fe 3 O 4 ) goethite (FeO(OH)) were prepared using microemulsion method dimethylene-1,2-bis (dodecyl dimethyl ammonium bromide) (CTAB) a surfactant. The h...

Abstract In this study, polymer/glass fiber fabric‐based nanocomposite plates were fabricated with 0.01%–0.1% single‐walled carbon nanotubes (SWCNTs) and filler materials (barite, magnetite, colemanite) using a hand layup process. Mechanical properties (e.g., tensile strength, flexural Charpy impact strength), thermal conductivity, radiation shielding gamma neutron radiation) of the specimens d...

The reactivity of iron(II/III) oxide surfaces may be influenced by their interaction with silica, which is ubiquitous in aquatic systems. Understanding the structure–reactivity relationships Si-...

Current inductors are the major impediment for miniaturization of electronics, due to the lack of magnetic materials with suitable high frequency properties. Future economically viable miniaturized high frequency electronic components require a low loss high frequency magnetic nanocomposite paste that is compatible with the low temperature powered circuit board (“PCB”) process. Inframat Corpora...

In continuation to our recent study on the synthesis and characterization of starch-silica nanocomposite, in the present study the nanocomposite has been evaluated for the removal of Cd(II) from the aqueous solution. The conditions for the sorption have been optimized and kinetic and thermodynamic studies were performed to understand the adsorption behaviour of the composite. Though the cadmium...

Tridymite, a low-pressure, high-temperature (>870 °C) SiO2 polymorph, was detected in a drill sample of laminated mudstone (Buckskin) at Marias Pass in Gale crater, Mars, by the Chemistry and Mineralogy X-ray diffraction instrument onboard the Mars Science Laboratory rover Curiosity The tridymitic mudstone has ∼40 wt.% crystalline and ∼60 wt.% X-ray amorphous material and a bulk composition wit...

We present the spectral and nonlinear optical properties of ZnO-SiO2 nanocomposites prepared by colloidal chemical synthesis. Obvious enhancement of ultraviolet (UV) emission of the samples is observed, and the strongest UV emission of a typical ZnO-SiO2 nanocomposite is over three times stronger than that of pure ZnO. The nonlinearity of the silica colloid is low, and its nonlinear response ca...
