The aim of this study was to use a life-cycle perspective to model the quantities of engineered nanoparticles released into the environment. Three types of nanoparticles were studied: nano silver (nano-Ag), nano TiO2 (nano-TiO2), and carbon nanotubes (CNT). The quantification was based on a substance flow analysis from products to air, soil, and water in Switzerland. The following parameters we...

the presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. to this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the research field of natural resources institute in damavand, iran. the first factor ...

in this study, the effect of nano-silver (ag) treatment on the drying rate and final moisture gradient of poplar wood was investigated. poplar (populous nigra) boards with green dimensions of 100×70×50 and 20 mm were treated with nano-silver (ag) suspension by spraying and immersion method. two concentrations of nano-silver suspension, including 20 and 100 ppm were used. then, the boards were c...

BACKGROUND Staphylococcus aureus biofilms contribute significantly to the recalcitrant nature of chronic rhinosinusitis. In previous studies, it has been shown that silk fibroin-nano silver solution can eliminate S. aureus biofilms in vitro, which suggests a potential role of this novel agent in the treatment of biofilm-associated diseases, such as sinusitis. OBJECTIVE The aim of this study w...

The functionality of flexible metal electrodes relies on the stable performance of a metallic film. In this study, highly stretchable anisotropic structures are designed to investigate the behaviour of silver electrodes on polydimethylsiloxane. Treated using both the oxygen plasma and the surface chemical functionalization technology, the film resistivity was reduced to 5.856 × 10(-9) Ω m after...

a green low-cost and reproducible yeast mediated synthesis of silver nanoparticles is reported. the synthesis is performed at room temperature. x-ray and transmission electron microscopy analyses are performed to ascertain the formation of ag nanoparticles. nanoparticles almost spherical in shape having a size of 6-20 nm are found.

this study was conducted to evaluate the long-term effects of in ovo injection of nano-silver, thyme and savory extracts in broiler breeder eggs on growth performance, lymphoid organ weights, immune and blood parameters and bone mineral concentration of broiler chicks. a total of 560 fertilized broiler breeder eggs were divided into 7 groups. on d 5 of incubation, eggs were treated with the fol...

Silver nanoparticles were successfully synthesized using silver nitrate and Gossypium hirsutum leaves extracts by varying the different concentration of aqueous & ethanolic extract. The extract was containing phytoconstituents like carbohydrates, proteins, glycosides, flavonoids, alkaloids, tannins phenolic compounds. Formation Nano Particles primarily confirmed colour change yellow to brow...

nowdays,  iron  nanoparticles  due  to  their  unique  characteristics  are used  in  all  of  sciences  and  technology.  these  nano  particles  due  to their  electrical, magnetic,  optical  and  catalytic  properties  and  having high  area  and  activity  that  is  promped  by  their  small  size  and most importantly  many  scientists  from  the  entire  world  are  interested  in their  ...
