Fe–Si–B amorphous alloy ribbons (Fe–Si–BAR) are widely investigated recently due to its high efficiency in remediation of wastewater containing azo dyes and other organic pollutants. In this paper, the effects of Fe–Si–BAR on the remediation of water containing high levels of Cu2+ ions were discussed. Results show that the reaction mechanism of Fe–...

Nano-fiber structure of ZnO and Ni doped ZnO (Ni:ZnO) transparent thin films have been deposited on glass substrate at 350 °C at an ambient atmosphere via spray pyrolysis technique. The structural, surface morphological and opto-electrical properties of ZnO and Ni doped ZnO thin films have been investigated. The XRD patterns show that the films are...

A kinetic model has been proposed in the present work, which formulates the dynamic nature of autocatalysis. The autocatalytic factor is quantified in the present work which involves interaction energy between bainite nucleus and stress field generated by existing bainite. This interaction energy provides the stored energy for autocatalytic nucleat...

The dielectric permittivity in polymers, fluoroelastomers and ethylene propylene diene monomers was measured as a function of both frequency and temperature. Several relaxation processes were revealed and analyzed through a developed algorithm to analyze the relaxation. The β and the α relaxations were observed and occurred in that order as the tem...

Using persulfate (PS) oxidation to remove the persistent perfluorooctanoic acid (PFOA) in water typically requires an elevated temperature or an extended reaction time. Under relatively ambient temperatures (15-45 °C), feasibility of employing PS with iron-modified activated carbon (AC) for PFOA oxidation was evaluated. With presence of Fe/AC in PS...

A standard solid-state ceramic technology (i.e., high-temperature solid-state reaction method) was used to fabricate new bismuth layer Aurivillius compound, BiLa2TiVO9. The formation of a single phase with an orthorhombic structure was confirmed by the X-ray diffraction structural analysis. The tangent loss measured at 200 °C is found to be in betw...

Applications of nitrous oxide (N2O) as an oxidant in green propellants and propulsion systems have attracted a lot of attention. In this study, the reaction pathways for the oxidation of ammonia (NH3) with N2O were studied using the B3LYP/6-31++G** method of density functional theory (DFT). The results reveal that the reaction between N2O and NH3 p...

This study set out to evaluate the influence of carbon black (CB) on the rheological properties and activation energy of asphalt binder at high service temperatures. The rheological performance of virgin and modified asphalt binders are investigated using three evaluation approaches: (1) Superpave specification parameter (G*/sinδ), (2) multiple str...

Although having a full picture of the heat-induced alterations in the fine structure of cellulosic materials is essential for designing their thermal processing, there have been no reliable methods to identify thermal transition temperatures. This study shows that colorimetric, thermogravimetric, and thermal kinetic parameters were sensitive to the...
