Infection is quite usual for implants after surgery and a systemic administration of antibiotics causes problems before the eradication of bacteria. Localized drug delivery from implants is an effective way by which the mentioned target can be met. In the current work, ordered mesoporous magnesi...

A sodium polyacrylate/sodium silicate binder used in oxidation resistant coating was investigated, and its effect on oxidation behavior of titanium alloy was studied at 800 °C in air. Glass-ceramic coating slurry mixed with the binder had good dispersity and stability. The coating was deposited...

In the ceramic technological processes, the suspensions with high concentration of ceramic particles (> 60%) play a very important role because this let to obtain inter alia reasonable casting rates what is one of the most important steps during the ceramics manufacturing. The article shows the ...

Long-term estimates of the dissolution of silicate rock are generally derived from a range of isotopic proxies, such as the radiogenic strontium isotope ratio (87Sr/86Sr), which are preserved in sediment archives. For these systems to fairly represent silicate weathering, the changes in isotopic...

In order to improve the osteoconductivity and the osteoinductivity of bone tissue engineering scaffold, a novel bi-phase strontium-doped magnesium phosphate/calcium silicate (Sr-MP/CSC) composite scaffold was fabricated by the self-solidifying/particulate leaching method. The bi-phase compositio...

In this work, an inorganic-salt coprecipitation route was used to synthesize nanostructured diopside (CaMgSi2O6) powders without/with 2 mol% strontium substituted for calcium. A sponge replication technique was then employed on the powders to manufacture highly porous scaffolds with pore interco...

A significant need exists today to develop novel alternatives to traditional bone grafts. Here, we report the potential use of mechanochemically synthesized hydroxyapatite (HA), silicate-, or strontium-containing HA microparticles and microparticle aggregates in combination with polycaprolactone...

Silica gel plays an important role in the formation of some biomorphic minerals (e.g. silica-carbonates) with morphologically complex micro/nanostructures in a pure inorganic system. Herein, we demonstrate the potential of strontium zinc silicate (Sr2ZnSi2O7, SZnS) bioceramics as a biomorphic mi...

The structural properties and the 4f→5d transitions of Ce3+ in strontium silicates (Sr3SiO5 and Sr2SiO4) were investigated using the density functional theory (DFT) with the supercell models and the wavefunction-based CASSCF/CASPT2 embedded cluster methods. The calculated 4f→5d transition ener...

The sorption of antimony (V) from 9.55 × 10−7 to 9.55 × 10−5 mol dm−3 on the sand of Haro river (10 mg-1 g) has been investigated to optimize the maximum adsorption with respect to the selection of an appropriate electrolyte, shaking time, concentration of antimony and amount of sand. Maximum ...

In this article, antimony-doped tin oxide (ATO) nanoparticles was synthesized by a facile polymer-pyrolysis method. The pyrolysis behaviors of the polymer precursors prepared via in situ polymerization of metal salts and acrylic acid were analyzed by simultaneous thermogravimetric and differenti...

This paper reports about the application of the solution-sol-gel method for the elaboration of multicomponent oxide catalysts supported on TiO2-Mo3 gels. To increase the specific surface area of the gel treating of the precursors in supercritical conditions has been used. V-W-Sb-Bi-O oxides supp...

A vanadium–antimony mixed oxide catalyst has been prepared via slurry method. The precursors obtained were calcined in different calcination temperatures, i.e. 673, 773 and 873 K and compared its effect on the physicochemical properties of the oxide. These catalysts were characterised by X-ray ...

The ultrathin peroxoantimonate coating of graphene oxide from hydrogen peroxide-rich solutions of hydroxoantimonate is demonstrated. An amorphous 1–2 nm Sb (V) oxide film is formed and can be further crystallized by exposure to an electron beam to give a 2–5 nm thick supported Sb6O13 particula...

This short review revisits the progress achieved in the last 10–15 years in the field of hybrid electrochromic materials, synthesized through sol–gel methods. New research directions in the field of electrochromism (EC), together with novel applications of many electrochromic hybrid oxides are...

In this work we report the effects on structural and conductivity properties of incorporating different amounts of antimony ions into vanadium pentoxide xerogel. Powder X-ray diffraction, Fourier-transform infrared spectroscopy, electronic paramagnetic resonance and thermogravimetric analysis we...

Radioactive strontium (90Sr) is one of the major contaminants in low-level radioactive wastewaters from nuclear power plants. Antimony silicate is regarded as a selective inorganic adsorbent for 90Sr removal. In this paper, a safe method was developed to prepare antimony silicate adsorbents. In ...

Over the past few decades, many countries have issued legislation for risk based management of contaminated soils, sediments and water. Establishing appropriate guidelines for risk based management of antimony contaminated environments is of great importance due to its toxicological properties. ...

The synthesis of poly[3-chloromethyl-3-(1,1,2,2-tetrahydro-perfluoro-octyl-oxy)methyl oxetane] has been performed in four steps. Chlorination of pentaerythritol produced a mixture of halogenated alcohols, which, in an alkaline medium, led to a mixture of hydroxylated and chlorinated oxetanes. Of...

Drilling of NiTi alloys under two lubricant-coolant strategies; namely flood and minimal quantity nanolubricant; two types of carbides drills, and three cutting speeds was investigated. Progressive tool wear, tool-life, drilling thrust force, surface finish quality, and dimensional accuracy were...
