Ameliorating Effect of β-Carotene on Gene Expression Alteration in Spermatozoon Cultured With Titanium Oxide
Introduction: In the present study, we assessed the effects of β-carotene on Titanium oxide Nanoparticle (TNP) induced mouse Spermatozoon Stem Cells (SSCs) apoptosis, at molecular level. Methods: After isolation from cryptorchid mouse testis and characterization, spermatogonial stem cells were divided into four groups. In the control group, spermatogonial cells were cultured in &alp...
متن کاملProduction of titanium tetrachloride (TiCl4) from titanium ores: A review
Titanium (Ti) is the ninth most abundant element on earth. The titanium mineral ores are widely distributed in different parts of the world. The two main ores of titanium include rutile (TiO2) and ilmenite (FeO.TiO2). It is aimed to provide the readers with an insight to the main processes currently employed to extract and recover titanium tetrachloride (TiCl4) from different titanium ores. Due...
متن کاملSynthesis of Nano-Sized Titania Particles by Hydrolysis of Titanium Tetrachloride
Nano-sized titanium dioxide TiO2 powder was successfully prepared from its precursor titanium (IV) chloride by a simple and new wet chemical method. TiCl4 were used as precursor in hydrogen peroxide, H2O2 and ethanol. This solution was then peptized using nitric acid and heated under reflux at 80°C. Their physico-chemical properties were then characterized by transmission electron microscopy (T...

متن کاملPreparation of titanium dioxide (TiO2) from sludge produced by titanium tetrachloride (TiCl4) flocculation of wastewater.
Sludge disposal is one of the most costly and environmentally problematic challenges of modern wastewater treatment worldwide. In this study, a new process was developed, which has a significant potential for lower cost of waste disposal, protection of the environment and public health, and yield of economically useful byproducts. Titanium oxide (TiO2), which is the most widely used metal oxide...
