At present, nanoparticles are beginning to influence our lives in many ways and understanding the environmental health and safety aspect of nanomaterials has become a crucial issue. The aim of the work was to assess and compare the acute toxicity of 31 different nanomaterials to fish mature individuals Danio rerio with that to fish early life stages on using evaluation of the 48- and 96- hour L...

The plasma-based aerosol process developed for the direct coating of particles in gases with silicon oxide in a continuous chemical vapor deposition (CVD) process is presented. It is shown that non-thermal plasma filaments induced in a dielectric barrier discharge (DBD) at atmospheric pressure trigger post-DBD gas phase reactions. DBD operating conditions are first scanned to produce ozone and ...

The purpose of this work is a detailed comparison of the fundamental magnetic properties of nanocomposite systems consisting of Fe3O4 nanoparticle-loaded porous silicon as well as silicon nanotubes. Such composite structures are of potential merit in the area of magnetically guided drug delivery. For magnetic systems to be utilized in biomedical applications, there are certain magnetic properti...

Magnetic nanoparticles (NPs) have been assembled in films by using self-assembled monolayers (SAMs) of organic molecules. SAMs were prepared by the reaction of organotrialkoxysilanes with surface silanol groups of silicon wafers. SAMs were prepared and their surface was decorated either by amine or thymine groups which have the ability to immobilize iron oxide nanoparticles as monolayers. These...

Silicon used in this study: The active material we use in this work is made of Si nanoparticles. Its BET surface was found to be around 13 m².g-1. In addition, XRD (Figure S1) and TEM (Figure S2) characterizations were carried out on this material. Figure S1. XRD diagram of the active material used in this study. The diagram was acquired on a Brücker D8 Advance diffractometer θ-θ configuration ...

in order to study the effect of vermicompost containing copper oxide and zinc oxide nanoparticles on was beans, in an experiment factorial were done based on a randomized complete block design in three replications. the experiment treatment were as follows: nanoparticles in 4 levels (0, 0.4, 0.8 and 1.2 g/kg weight of substrate), vermicompost in 3 levels (2.5, 5 and 7.5 g/kg-1 weight of substra...
