Natural sources of mercury come from volcanoes, forest fires and the weathering of mercury-bearing rocks. However, this is small compared to the vast amount of mercury which is generated from anthropogenic sources (human activities), such as fossi...

In this research, a group of samples of a polymer to which silicon dioxide was added were prepared, with different concentrations, by the casting method. And then using a spectrophotometer to study the absorbance and then extract the refractive in...

In this research, we discussed the laser, how it was developed, when it was discovered, what are the capabilities of the laser, the conditions for the occurrence of the laser, the principle of its operation, the characteristics of the laser, and f...

Polyvinyl Alcohol (PVA), a synthetic polymer with unique properties, has garnered significant attention since its first commercialization in the 1930s. Research on PVA systems and its applications has continuously evolved, focusing on its reactivi...
