Ruthenium N719 is a well-known material used as the dye in commercial dye-sensitized solar cell (DSSC) devices. However, it poses risks to human health and environment over time. On other hand, titanium dioxide (TiO2) has low electron mobility high recombination losses when photoanode this photovoltaic technology device. In addition, using harms health. As an alternative sensitizer compensate o...

Titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles (NPs) are promising candidates for numerous applications in consumer products. This will lead to increased human exposure, thus posing a threat to human health. Both these types of NPs have been studied for their cell toxicity, immunotoxicity, and genotoxicity. However, effects of these NPs on epigenetic modulations have not been studie...

Pharmaceuticals have become an important public health issue as environmental pollutants over the last years. After ingestion, pharmaceuticals are partly excreted unchanged. They can reach the wastewater treatment plant (WWTP) via the sewer network. Because the conventional treatments are ineffective in their removal, new methods should be approached, for example semiconductor photocatalysis. S...

Photocatalytic degradation of organic components in water by means of TiO2 nanosuspensions under ultraviolet (UV) irradiation represents an efficient method for water purification. In the present paper, a modeling approach is proposed to simulate the involved kinetic processes based on the Langmuir– Hinshelwood mechanism. The extended model also includes the formation of intermediate organic co...

Purpose: The aim of this study is to develop bromhexine hydrochloride 1 %w/v oral solution for veterinary use and to evaluate its stability. Methods: Solutions of Bromhexine hydrochloride (1%w/v) were prepared by dissolving bromhexine hydrochloride in benzyl alcohol at 50 °C then alcohol 96 % v/v; Tween 80 and purified water were added. The obtained solution was filled in amber glass bottles, a...

The increasing production and use of engineered nanomaterials (ENMs) inevitably results in their higher concentrations in the environment. This may lead to undesirable environmental effects and thus warrants risk assessment. The ecotoxicity testing of a wide variety of ENMs rapidly evolving in the market is costly but also ethically questionable when bioassays with vertebrates are conducted. Th...
