The influence of milling and subsequent annealing on nickel-ferrite phase formation was investigated by X-ray diffraction (XRD). Microstructure and magnetic properties of NiFe2O4 were determined by field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and vibration sample magnetometry (VSM). Single phase nanosized nickel-ferrite was obtained by 30 h mechani...

In recent years, metal nano particles such as silver, copper and zinc have developed in textilefinishing. Copper nano particles are used in wound dressings and socks to give them antibacterialproperties. In the present paper, cotton fabrics were treated with different concentrations of Cu nanoparticles colloidal solution. For investigation of the durability of nano particles on cotton fabric,la...

Ferromagnetic nanomaterials are of particular interest, because at nanoscale a crystallite can exhibit a single magnetic domain. These nanomaterials therefore exhibit different magnetic properties as compared to bulk. Recently, barium ferrite has gained importance due to its potential use in magnetic recording and in microwave devices. Barium ferrite nanoparticles are prepared by the citrate pr...

Most studies of the role of biological entities as atmospheric ice-nucleating particles have focused on relatively rare supermicron particles such as bacterial cells, fungal spores and pollen grains. However, it is not clear that there are sufficient numbers of these particles in the atmosphere to strongly influence clouds. Here we show that the ice-nucleating activity of a fungus from the ubiq...

Sn–Ag–Cu composite solders reinforced with nano-sized, nonreacting, noncoarsening 1 wt% TiO2 particles were prepared by mechanically dispersing TiO2 nano-particles into Sn–Ag–Cu solder powder and the interfacial morphology of the solder and flexible BGA substrates were characterized metallographically. At their interfaces, different types of scallop-shaped intermetallic compound layers such as ...

titanium dioxide (tio2)nanoparticles have been frequently employed in the environmental treatment and purification purposes as a cheap and highly efficient photocatalyst. a photocatalyst can facilitate the breakdown and removal of a variety of environmental pollutants at room temperature. tio2 photocatalyst is the best candidatebecause of its strong oxidized ability, non-toxicity and longtherma...

in this study, selenium was recovered from an industrial dust. after the purification process, the researchers were able to prepare selenium micro powder. the objective of this study was to prepare selenium nano particles by water solution phase method from the micro powders. the results showed that selenium micronized powder and nano particles had high purity. the obtained nanoparticles were t...

AIM Biomimetic nano-assembly formation offers a convenient and bio friendly approach to fabricate complex structures from simple components with sub-nanometer precision. Recently, biomimetic (employing microorganism/plants) synthesis of metal and inorganic materials nano-particles has emerged as a simple and viable strategy. In the present study, we have extended biological synthesis of nano-pa...

This study investigated water-soluble ions in the sized particles (particularly nano (PM(0.01-0.056))/ultrafine (PM(0.01-0.1))) collected using MOUDI and Nano-MOUDI samplers near a busy road site and at a rural site. The analytical results demonstrate that nano and coarse particles exhibited the highest (16.3%) and lowest (8.37%) nitrate mass ratios, respectively. The mass ratio of NO(3)(-) was...

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 ...
