Magnesium phosphate cements (MPC) are materials prepared by reacting magnesium oxide with water-soluble phosphates such as mono-ammonium dihydrogen phosphate (ADP), which solidify at ambient temperature through the formation of hydrated phases in the material. A great advantage of these ceramics...
To reduce the emission of radioactive waste water and reuse high-value 10B-rich nuclear-grade boric acid from a nuclear power plant, a two-step membrane process was proposed based on the combination of two types of ceramic membranes. First, a ceramic nanofiltration membrane was used to purify th...
BackgroundEpidural fibrosis is a major problem after spine surgery, with some patients having recurrent symptoms secondary to excessive formation of scar tissue resulting in neurologic compression. We used a rat laminectomy model to determine if topical application of boric acid could be helpful...
In this paper, the removal of nuclides and boric acid from the simulated borate-containing radioactive wastewater was studied using forward osmosis (FO) process. The effect of membrane materials and their orientation, as well as borate concentration on the flux and retentions of nuclides and bor...
Dicyclopentadienylmagnesium, cyclopentadienylmagnesium chloride, cyclopentadienylmagnesium bromide, cyclopentadienyllithium and cyclopentadienylsodium were examined by UV, IR, and PMR spectroscopy in tetrahydrofuran. None of them exhibited UV maxima at >210 nm. All of their infrared spectra indi...
Antimony (Sb), a toxic metalloid, is soluble as antimonate (Sb(V)). While bio-reduction of Sb(V) is an effective Sb-removal approach, its bio-reduction has been coupled to oxidation of only organic electron donors. In this study, we demonstrate, for the first time, the feasibility of autotrophic...
Lead antimonate was used to produce opaque yellow glasses from the beginnings of glass production in the Near East and Egypt around 1500 BC through into the Roman period. The composition and crystallographic structure of lead antimonate particles present in a small group of New Kingdom Egyptian ...
At 298 K cation conducting mixed antimonate Na0.8Ni0.6Sb0.4O2 exhibits an O3-type structure, with sodium ions in a distorted octahedral coordination, space group R-3m, a = 3.0496(1)Å, c = 16.4060(4)Å. 23Na NMR at 197–288 K reveals two main types of sodium atoms in the structure, ascribed to 18g...
Arsenate and antimonate are water-soluble toxic mining waste species which often occur together and can be sequestered with varying success by a hydrous ferric oxide known as ferrihydrite. The competitive adsorption of arsenate and antimonate to thin films of 6-line ferrihydrite has been investi...
In this work, a new nanohybrid consisting of copper oxide and zinc antimonate was designed using ultrasonication assisted homogenous magnetic stirring approach and investigated their performance as an electrode material for supercapacitors. Combination of the duo could enhance the electrical con...
The chemical structures of the pentavalent antimonial drugs, meglumine antimonate (MA) and sodium stibogluconate (SSG), were re-evaluated using electrospray ionization mass spectrometry (ESI-MS) and osmolarity measurements. Both MA and SSG were found to contain 1:1, 1:2, 2:2 and 2:3 SbV-ligand c...
The kinetics and the consequent self-diffusion of Na+ and Cs+ ions inside titanium(IV) antimonate have been studied during their removal from the waste streams at three different reaction temperatures, namely, 25 ± 1, 45 ± 1, and 60 ± 1 °C. The diffusion coefficients have been determined usi...
The priority pollutant antimony (Sb) exists primarily as Sb(V) and Sb(III) in natural waters, and Sb(III) is generally with greater mobility and toxicity than Sb(V). The bio-reduction of Sb(V) would not become a meaningful Sb-removal process unless the accumulation of produced dissolved Sb(III) ...
Earlier, we have reported the results of quantitative studies on structural and a variety of physical properties (that include non-linear optical, piezo-optical and electrical characteristics) of Na2O-Sb2O3:Ag2O/Au2O3 glass ceramics. In continuation of these studies, this part of the investigati...
The objective of this work is to explore the Ag ion concentration dependence on structural and dielectric characteristics of Na2OSb2O3: Ag2O glass ceramics. The prepared glass ceramics were characterized by XRD, XPS, SEM, TEM, EDS and DSC techniques. These studies have revealed that the samples ...
The hepatoprotective effect of freeze-dried methanolic leaf extract of Ginkgo biloba was evaluated against lantadenes-induced hepatic damage in guinea pigs. The reversed-phase HPLC analysis of lantadenes confirmed the presence of 72.82% of lantadene A. UPLC-ESI-MS analysis showed the presence of...
A series of microphase-separated, hierarchical macroporous polyurethane (PU) polyHIPEs with high-porosity, highly interconnected, open-cell structures have been fabricated from nonaqueous high internal phase emulsions (HIPEs). These paraffin oil-in-dimethyl sulfoxide nonaqueous HIPEs, stabilized...
In this study, gold amalgam was prepared on a gold nanorods (Au Rs) modified ITO electrode through an electrochemical reduction of mercury ions (Hg2+), and the formation of amalgam was explored under steady and non-steady states. Under static system, Hg2+ was preferentially deposited at the tips...
Superhydrophobic surfaces have a wide application prospect in the future industrial production due to its special abilities. The fabrication of superhydrophobic coating on metal surfaces can improve its performance. A one-step electrodeposition method is proposed to construct nanostructures on t...
Beryllium copper alloys are the ideal materials to fabricate the supporting parts owing to their excellent physical and chemical properties. Many high aspect ratio micro-holes are often required to realize the special missions. However, they were not easily fabricated by the traditional machinin...
