Investigation of hematotoxic effect of nano ZnO, nano Fe3O4 and nano SiO2 in vitro
Objective(s): Evaluation of nanomaterials interaction with blood ingredients is a part of preclinical risk assessment of newly-synthesized materials, especially for nano-sized pharmaceuticals which are intravenously administrated. The red blood cells (RBCs) are susceptible to oxidative stress damage. This study was designed to evaluate induced oxidative hematotoxic effect of na...
متن کاملExperimental Study on the Physical and Rheological Properties of Bitumen Modified with Different Nano Materials (Nano SiO2 & Nano TiO2)
This study is carried out to explore the effect of nano materials (SiO2 & TiO2) on the physical and rheological properties of Bitumen. To achieve this goal, Nano materials are blended in bitumen in various percentages (0.3, 0.6, 0.9 and 1.2%). The physical and rheological properties of modified binders are characterized using a penetration, softening point, kinematic viscosity and a dynamic...
متن کاملSynthesis and nano structural study on TiO2-NiO-SiO2 composite
We report on the synthesis, morphology, chemically and structurally of TiO2-NiO-SiO2 nanostructure. The TiO2-NiO-SiO2 nanostructure was synthesized by a method based on the sol-gel method, by the simultaneous gelation of all cations. The coatings were deposited on dried soda-lime glass slides by spin coating. Composite powders and coating on glass hav...
متن کاملEffect of Nano-SiO2 on the Hydration and Microstructure of Portland Cement
This paper systematically studied the modification of cement-based materials by nano-SiO₂ particles with an average diameter of about 20 nm. In order to obtain the effect of nano-SiO₂ particles on the mechanical properties, hydration, and pore structure of cement-based materials, adding 1%, 3%, and 5% content of nano-SiO₂ in cement paste, respectively. The results showed that the reaction of na...
متن کاملThermal Inactivation and Aggregation of Lysozyme in the Presence of Nano- TiO2 and Nano-SiO2 in Neutral pH
Protein aggregation is a problem in biotechnology. High temperature is one of the most important reasons to enhance enzyme inactivation and aggregation in industrial systems. This work focuses on the effect of TiO2 and SiO2 nanoparticles on refolding and reactivation of lysozyme. In the presence of TiO2 and SiO2 nanoparticles, after enzyme heat treatment at 98C for 30 min, not only aggregates w...
