The effect of pro-degradant manganese (Mn) stearate concentration on the oxidative abiotic degradation of high-density polyethylene (HDPE) was investigated in thermo-oxidative tests at three temperatures (60, 70 and 80 °C) over time. Degradation monitoring was carried out, by determining carbon...

The formation and transport of geogenic metal nanoparticles in mining-impacted environments is a developing concern because of their potential for greater distribution compared to larger particles. Discharge from the abandoned Gem Mine in the Coeur d'Alene Mining District of northern Idaho ...

This paper deals with the loading of halloysite nanotubes (HNTs) with Zn2+ cations. The aluminol groups of HNTs were grafted by 3-aminopropyltriethoxysilane (APTES) to enhance Zn2+ loading. FTIR proved modification of HNTs. Electrochemical evaluations of bare steel in saline solution showed high...

Sodium carbonate-soluble pectin fraction forms a self-organized network on mica and may have the potential ability to bind zinc ions. The aim of this research was to characterize the interaction of zinc ions with this fraction extracted from apples using rheological measurements and FT-IR study....

Oxide fraction of zinc ash originating from hot dip galvanizing plant was investigated. Chemical and phase compositions of the material were characterized in details. The zinc ash contained simonkolleite, zinc oxide and metallic zinc as main phases. Influence of solid to liquid ratio (150–500 k...

In this work, the effect of Zn2+ cations on the calcareous scales during the cathodic protection of mild steel was studied. The Zn2+ cations were introduced into the epoxy and alkyd coatings in the form of zinc chloride. Also, the influence of Zn2+ cations was investigated in the zinc -rich prim...

Columns and papers of titanium arsenate have been utilized for chromatographic studies of several alkaloids in aqueous and mixed solvent systems. The results have been compared with those obtained with plain papers. A number of separations have been achieved on papers impregnated with titanium a...

Publisher SummaryThis chapter discusses strychnine. Strychnine is an indole alkaloid that occurs in numerous strychnos plants of the family Loganiaceae. Strychnine was first discovered in 1817 by the French Pharmacists, Pierre Pelletier, and Joseph Caventou; these workers were also responsible f...

Herein, we have discussed change in dielectric and optical properties due to dispersion of Strontium hardystonite (Sr-HT) in the pure nematic liquid crystal (LC). The two different (0.5% wt./wt. and 1.0% wt./wt.) concentration of Sr-HT are dispersed in the pure nematic LC. After the dispersion o...

The bioactivity of calcium phosphate (CaP) coatings can be controlled by different CaP phase precipitation and/or addition of foreign ions to their crystal lattice. Cationic substitution of strontium (Sr) into CaP coatings has gained a great attention due to the unique potential of Sr ions on st...

Synthesis of strontium-doped hydroxyapatite from Mercenaria clam shells has been carried out by hydrothermal method. The doping of bioceramic, processed from biogenic resources is mostly unexplored. The objective is to understand the effect of strontium (Sr) incorporation on phase stability, sin...

Hydroxyapatite (HA)/reduced graphene oxide (rGO) composites with different mol% of strontium and 1 wt% of GO were fabricated through a green hydrothermal reduction method and this combination has been reported for the first time. All the synthesized composites had strontium incorporated onto the...

The bromine concentration was determined by means of molecular absorption of strontium monobromide (SrBr) generated in the gas phase of the vaporizer of a high-resolution continuum source electrothermal atomic absorption spectrometer. For this purpose, the wine and drug samples were introduced i...

Strontium hydroxyapatite (SrHAp) is not only used as drug carrier material for bone disease treatment, but also has application prospect in bone tissue engineering. But SrHAp is prepared with by-products strontium hydrogen phosphate (SrHP) and strontium phosphate (TSrP), which requires accurate ...

In this work, potassium strontium bromide activated with divalent europium, (KSr2Br5:Eu) has been studied. It has a monoclinic crystal structure and a density of 3.98 g/cm3. Two single crystals of KSr2Br5 doped with 5% Eu2+, with diameters of 13 mm and 22 mm, were grown in a two zone transparent...

Thermochemical energy storage has the potential to provide efficient, compact and long duration storage of thermal energy. Major advancements, however, are needed for such a technology to meet performance and cost targets. Here we present a study on novel composites for low to medium temperature...

Thermochemical heat storage exploits thermal solar energy to produce sustainable residential heating, obtained by exothermal reaction between bromides and water vapour. A protocol to test the corrosion of surrounding materials is discussed in the case of SrBr2 contacting copper or steel. Corrosi...

Strontium bromide, SrBr2, has a strong potential for the recovery, storage and controlled release of low grade heat (

Sensitive, specific, and reproducible TLC methods are described for the determination of propranolol and its major metabolites in humans, conjugated propranolol, free and conjugated naphthoxylactic acid, and free and conjugated p-hydroxypropranolol. The drug or metabolites are extracted from pla...

We examined the metabolism of N-desisopropylpropranolol (NDP), which is generated from propranolol (PL) by side-chain N-desisopropylation, to naphthoxylactic acid (NLA) in rat liver. S(−)-NDP (S-NDP) and R(+)-NDP (R-NDP) were enantioselectively metabolized to NLA in isolated rat hepatocytes and ...
