Abstract The influence of cobalt, copper, iron(III), manganese and zinc nitrate salts on phase transitions thermal stability ammonium (AN) has been studied discussed. Differential analysis/differential scanning calorimetry coupled with thermogravimetry mass spectrometry were used to evaluate the analyzed systems. Each salt was appropriately mixed create samples AN:salt ratios 4:1, 9:1 49:1. It ...

Keratinocyte proliferation and migration are essential for the reconstruction of the cutaneous barrier after skin injury. Interestingly, thermal waters which are rich in trace elements (e.g. boron and manganese), are known to be able to improve wound healing. In order to understand the mechanism of action of this effect, our study investigated the in vitro modulation of keratinocyte migration a...

Background: Some metals play an important role in  biological reactions  and metabolism of human body. Low and high concentrations of these elements can cause diseases and poisoning. This study was carried out in order to investigate the concentration of metals in inlet and outlet water of households in Ahvaz city, Iran in 2018. Materials and Methods: This was a cross-sectional descriptive stud...

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

An effect of promoters such as calcium, aluminium, and potassium oxides and also addition of chromium and manganese on the structure of cobalt catalysts was examined. Studies of the catalytic ammonia decomposition over the cobalt catalysts are presented. The studies of the ammonia decomposition were carried out for various ammonia-hydrogen mixtures in which ammonia concentration varied in the r...

The present study focused on central nervous system (CNS) transport kinetics of manganese phosphate and manganese sulfate; these findings were correlated with the transport kinetics of manganese chloride (MnCl2), a model Mn compound that has been previously studied. A series of studies was performed to address the transport of Mn salts in confluent cultured endothelial cells. The initial rate o...

The interest in the synthesis of metallic complexes of different drugs to make them moreefficient in biological environment of the human body is seen for the last few decades. Widerange of metal complexes are already used in clinical practice which encourages additionalresearch for innovating new metal based drugs, such as metal-mediated antibiotics, antiparasitic,antiviral, antibacterial, and ...
