Abstract Background Nano-particles of metals can be routinely synthesized. The cereal seeds treatment with the particles improve early growth and crop production. Moreover, is robust economical. Methods Metal (Fe 0 , Cu Co ), zinc oxide (ZnO) chitosan-stabilized silver nano-particles were synthesized applied to seeds. germination rate, plant development inhibition effects on pathogenic fungi qu...

Plenty of research has verified that nano-ZnO particles could improve the properties asphalt, but studies on nano-ZnO-modified asphalt haven’t been conducted at molecular level. Therefore, to investigate effect ZnO properties, structure and morphology dynamics (MD) methods were carried out. In this study, models cluster ZnO/asphalt blending systems with different particle sizes built using Mate...

Previous studies have reported little correlation between the relative toxicity of particle types when comparing lung toxicity rankings following in vivo instillation versus in vitro cell culture exposures. This study was designed to assess the capacity of in vitro screening studies to predict in vivo pulmonary toxicity of several fine or nanoscale particle types in rats. In the in vivo compone...

Background & Objectives: Nanotechnology is one of great important part of technology. Nanoparticles can be used in different applications for industrial, medical, military and personal use. The objectives of this study were preparation of Polystyrene/ZnO nanocomposite films via a simple method and investigation of antibacterial activity of them. Materials and Methods: Polystyrene/ZnO nanopartic...

An experiment was conducted to study the effect of seed invigoration with inorganic nanoparticles on plant growth and yield chilli. Seed nano particles ZnO TiO2 found be beneficial in improving attributes. treatment @ 1300 mg kg-1 900 exhibited increased height, fruits per plant, fruit length, yield, number seeds yield.

OF THESIS TRANSFORMATIONS, BIOAVAILABILITY AND TOXICITY OF MANUFACTURED ZnO NANOMATERIALS IN WASTEWTER In order to properly evaluate the ecological and human health risks of ZnO Manufactured nanomaterials (MNMs) released to the environment, it is critical to understand the likely transformation products in the wastewater treatment process and in soils receiving biosolids. To address this critic...

Nanocomposite of ZrO2/ZnO was prepared under ultrasonic irradiation by sol gel process from directly mixing Zirconium and Zinc gels. The mixture was placed under ultrasonic irradiation for 2 hours. After the aging time and filtration of the reaction mixture, the filtrated composite gel was calcinated at 500 °C for 3h in furnace. The precursor gels of zirconium and zinc were prepared ...

STATEMENT OF THE PROBLEM During the orthodontic treatment, microbial plaques may accumulate around the brackets and cause caries, especially in high-risk patients. Finding ways to eliminate this microbial plaque seems to be essential. PURPOSE The aim of this study was to compare the antibacterial effects of nano copper oxide (CuO) and nano zinc oxide (ZnO) coated brackets against Streptococcu...
