silver nano-particles have different biological applications due to their compatibility. chemical methodsusually result in remaining some amounts of toxic reactions on the nano-particles. for this reason, the useof plants as sustainable and accessible resources in preparation of compatible nano-particles has attracteda lot of attention in the recent years. this research investigated the green s...

In the present study, nano-scale Zero Valent Iron (NZVI) was synthesized in ethanol medium by the method of ferric iron reduction using sodium borohydride as a reducing agent under atmospheric conditions. The obtained iron nanoparticles are mainly in zero valent oxidation state and remain without significant oxidation for hours. A systematic characterization of NZVI was performed using XRD, SEM...

in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertil...

Food fortification programs to reduce iron deficiency anemia require bioavailable forms of iron that do not cause adverse organoleptic effects. Rodent studies show that nano-sized ferric phosphate (NP-FePO4) is as bioavailable as ferrous sulfate, but there is controversy over the mechanism of absorption. We undertook in vitro studies to examine this using a Caco-2 cell model and simulated gastr...

in recent years, the scientists have focused on nanotecnology and its applications as the most important fields of research and development. the use of nanoparticles offers many advantages, due to their unique size and physical properties. magnetic iron oxide nanoparticles have been used in many fields, because of their unique properties such as large specific surface area and convenient separa...

abstract the aim of this study is laboratory investigation of nitrate reduction in water using fe/cu nano particles. in this regards, nano fe0 (54±4 nm) and fe/cu particles (75±3 nm) was synthesized and characterized by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and transmission electron microscopy (tem) photographs. the effects of coating load of nano-fe0 by cu (0, 5, ...

With the rapid growing of nanotechnology, the effects of nanomaterials released into the environment on plants have drawn more and more attention. Iron is an element essential for plant growth and development. Iron is involved in chlorophyll formation; iron deficiency will cause a plant disorder known as chlorosis. However, whether iron in nano-ferric oxide can be absorbed by plants were rarely...

globally, increasing nitrate concentrations have become a significant environmental problem and a potential risk to public health. the world health organization (who) has set a limit of (10 (mg.l -1 )) no 3 - for human consumption and (100 mg.l -1 )) no 3 - for animals. water above these limits requires denitrification. nitrates causes cancer, blue-bay syndrome, hypertension and thyroid hypertr...
