Arsenic is among the most toxic elements and it commonly exists in water as arsenite (As(III)) and arsenate (As(V)) ions. As(III) removal often requires a pre-oxidation or pH adjustment step and it is a challenge to adsorb As(III) at circumneutral pH. In this study, iron-aluminium double hydrous...

Many electrochemical reactions taking place in aqueous solution consume or produce protons. The pH in the diffusion layer can therefore be significantly altered during the reaction and there is a need for in situ pH measurements tracing this near surface pH. In the present paper the rotating rin...

Hydrous iridium oxide is a well-known material for its electrochromism and electrocatalytic activity, e.g. in oxygen and chlorine evolution reactions (OER) and (CER). Poor durability during the OER is, however, usually considered as a major drawback. In the current work dissolution of hydrous ox...

Surface plasmon resonance sensor coated with hydrous ferric oxide-magnetite-reduced (Fe2H2O4-Fe3O4-rGO) graphene oxide nanocomposite film was demonstrated to detect two toxic heavy metals; Arsenic (III) [As(III)] and Arsenic (V) [As(V)] in aqueous solution. The proposed nanocomposite film exhibi...

Geology presents a well-defined family of minerals in the case of crystalline magnesium silicates. However, in industrial water processes deposits that contain both “Mg” and “Si” are usually referred to as “magnesium silicate” scales. In this paper we attempt to delineate the true nature o...

A novel sensor aluminum silicate was used as a cheaper modifier for the rapid and sensitive voltammetric determination of dothiepin HCl (DTP). Cyclic voltammetry, scanning electron microscopy (SEM), electrochemical impedance spectroscopy (EIS), chronoamperometry (CA) and square-wave voltammetry ...

We investigated the effects of sintering temperature and time on the dielectric and mechanical properties, sintering, microstructure, crystallization, and thermal expansion coefficient of Magnesium aluminum silicate glass-ceramic for the applications of low temperature co-fired ceramics substrat...

Dye pollution in water environment is a significant threat to ecological and human health, and its removal is very important yet challenging. Magnesium silicate-based materials have proven to be good adsorbents for dye wastewater treatment. In consideration of recycling and practicability, flexi...

Magnesium silicate (MS) is a widely used adsorbent, and much work has been done to control the surface morphology of MS to improve its adsorption capacity. In this work, hierarchical MS was prepared by combining hydrothermal process with freeze drying technique for potential application in adsor...

Exfoliated nanocomposites of chitosan-magnesium aluminum silicate (CS-MAS) particles are characterized by good compressibility but poor flowability. Thus, the aims of this study were to investigate agglomerates of CS-MAS nanocomposites prepared using the agglomerating agents water, ethanol, or p...

In this study, the structure of synthetic magnesium silicate hydrated phases (M-S-H) and the distribution of water as a function of the Mg/Si ratio were investigated. Different analytical techniques indicated that M-S-H phases are nano-crystallite hydrated phyllosilicates with relatively short c...

Reactions between calcium magnesium aluminium silicates (CMAS) and Gd2Zr2O7 or 2ZrO2∙Y2O3 (ss) are investigated within a temperature range of 1200–1300 °C and for durations of 1 h–100 h. The evolution of CMAS penetration depth in Gd2Zr2O7 and 2ZrO2∙Y2O3 (ss) pellets varies considerably depend...

The aim of this study was to investigate the effect of clay, magnesium aluminum silicate (MAS), on the properties of sodium caseinate (SC) dispersions and films. Moreover, the SC-MAS dispersions were evaluated for film coating of modified-release tablets. The results showed that MAS addition led...

Fe3+ and Al3+ ions existed in phosphoric acid–nitric acid solutions are very troublesome for the neutralization process of nitrophosphate (NP) fertilizer. This paper studied the performances of three chelating resins (S957, S950 and S930) on the removal of Fe3+ and Al3+ ions from phosphoric aci...

Pursuing efficient and low-cost catalysts for the sluggish oxygen evolution reaction (OER) is imperative for the large-scale deployment of promising electrochemical technologies such as water splitting and CO2 electrochemical reduction. The earth-abundant perovskite catalysts based on LaNiO3-δ ...
