ObjectivesRecently a silver diamine fluoride and potassium iodide solution (Riva Star, SDI Australia) has been introduced for clinical use as a desensitizing agent or a cavity cleaner. Little is known whether the precipitate produced will affect adhesion to dentin. The aim of this study was to d...

In this work, a simple, selective, sensitive and inexpensive colorimetric sensor has been developed for the detection of iodide ions using green tea (Camellia sinensis) synthesized silver nanoparticles (tea-capped AgNPs). The mechanistic route relied upon the binding of iodide ions to the surfac...

The World Health Organization considers iodide deficiency diseases (IDD) to be a public health problem. The main indicator to access IDD is urinary iodide, since approximately 90% of the ingested iodide uses this clearance path, with urine being a preferable target for the analysis.In this work,...

This paper reports on a new method for sensitive and selective determination of iodide based on dynamic gas extraction with air flow and digital colorimetric detection using paper modified with silver triangular nanoplates (AgTNPs). Iodide is oxidized in a sample by Fe(III) to produce molecular ...

Synthetic zeolite-based Ag-nanocomposites were synthesized, characterized and used to remove iodide from aqueous solutions. The results showed high removal efficiency (up to 94.85%) and the formation silver iodide which is stable into the material. The maximum achieved adsorption capacity of the...

Treatment of carious root surfaces remains challenging due to the complex pathological processes and difficulty in restoring the original structure of root dentine. Current treatments targeting the de-/re-mineralisation processes are not entirely satisfactory in terms of the protection of the de...

A new way to improve the 1.53 μm emission in Er3+/Yb3+ co-doped multicomponent phosphate glass was demonstrated by introducing silver nanoparticles (NPs) in rare-earth doped glass. The existence of Ag NPs was confirmed by absorption spectra and transmission electron microscopy (TEM) measurement...

Gold- and silver-containing pyrites of the Tikhii area at the Julietta deposit (Engteri ore cluster, Magadan Region) were studied by optical and scanning electron microscopy and electron probe microanalysis. One- or two-phase rounded microinclusions consisting of electrum (450-680%c) and/or gale...

Due to the health concerns, the demand for Pb-free solder is greater than before. In the past, Sn-Pb solders were widely used in soldering process due to their excellent soldering characteristics and reliability. Pb-free solder, the Sn-8Zn-3Bi eutectic alloy is regarded as one of the best potent...

Two boron complexes of 1-(o-hydroxyphenyl)imidazo[1,5-a]pyridine, which were named as BOHPIP, have been synthesized. These complexes exhibited blue emission in solution with high quantum yields (ΦFL = up to 0.71). In addition, 1-(o-hydroxyphenyl)imidazo[1,5-a]pyridine-BPh2 complex showed the st...

Zinc oxide is highly attractive multifunctional material with its unique properties such as antifungal, antibacterial, semiconducting, UV filtering and piezo electric properties. Being nontoxic, bio safe, biocompatible material, it is used in extensive applications in biomedical, high performanc...

Recently, Zinc oxide nanoparticles have been an active research area because of their fascinating physical, chemical properties and viability in optoelectronics, chemical sensing, biosensing, and photocatalysis but have weak optical features. Optical properties can be tuned by doping. In this re...

A new solvothermal post-synthesis treatment for preparing high aspect ratio magnesium aluminium layered double hydroxides (MgAl–LDHs) has been developed. Treating laurate-intercalated MgAl–LDHs in pure ethanol in an autoclave for 48 h at 150 °C was found to produce delaminated MgAl–LDH nanos...

Rapid expansion of supercritical suspensions was used for the first time to push apart the layers in a layered metal hydroxide structure. Treatment with supercritical CO2 resulted in significant changes in interlayer distances in yttrium hydroxide intercalated with dodecyl sulfate anions. Accord...

The applicability of an extended Nernst–Planck equation-based model to predict the rate of boric acid transport during electodialytic (ED) desalination has been examined. Diffusive and convective mechanisms for boric acid transport were found to determine the boric acid transport rate. The effe...

In this study, the use of Amberlite IR–120, a strong acidic cation exchange resin, was investigated to remove calcium impurity from saturated boric acid solutions. Calcium impurity arised from high calcium content of colemanite ore is a very important problem as it increases impurity on the bor...

Regeneration of boron-selective sorbents produces the acidic effluents of high boron content. Electrodialysis was proposed as a method for hydrochloric acid regeneration from the effluents composed of 0.1 kmol/m3 hydrochloric acid and boric acid concentration ranging from 0.1 to 2.5 kg B/m3. Bor...

Boric acid recycling pump is used to maintain the circulation of boric acid solution for the need of nuclear safety protection. In a boric acid recycling pump, the pump shaft is an important component. As it is exposed to relatively harsh work environment, the pump shaft may encounter severe fai...

Boric acid has multiple uses in several industries, the pharmaceutical, glass and ceramic industries being some of them. Its obtaining involves the addition of sulfuric acid to slurry of calcium–sodium borate at 70 °C and, after the removal of insoluble undesired material, the crystallization ...

SummaryOptical anisotropy as dispersion of birefringence (DB) (birefringence studied for light of different wavelengths) and linear dichroism (LD) (selective absorption of polarized light) in stained substrates reflects their macromolecular orientation states. Birefringence interference colors o...
