The synthesis of Fe, Fe-Pt and Fe-Co nanoparticles were carried out using the bottom-up polyol process using standard ari free techniques. Using these nanoparticles, multiwalled carbon nanotubes were synthesized in an atmospheric pressure plasma enhanced chemical vapor deposition(APPECVD) process with a mixture of helium and acetylene gases. The APPECVD process produced dense carbon nanotube fo...

Nanoparticulate zero-valent iron (nZVI) rapidly reacts with oxygen to produce strong oxidants capable of transforming organic contaminants in water. However,the low yield of oxidants with respect to the iron added normally limits the application of this system. Bimetallic nickel-iron nanoparticles (nNi-Fe; i.e., Ni-Fe alloy and Ni-coated Fe nanoparticles) exhibited enhanced yields of oxidants c...

OBJECTIVE To evaluate the feasibility of using magnetic iron oxide (Fe(3)O(4))-dextran-anti-β-human chorionic gonadotropin (HCG) nanoparticles as a gene vector for cellular transfections. STUDY DESIGN Fe(3)O(4)-dextran-anti-β-HCG nanoparticles were synthesized by chemical coprecipitation. The configuration, diameter, and iron content of the nanoparticles were detected by transmission electron...

to study the impact of iron nanoparticles foliar application on mitigating the effects of drought stress on yield, yield components and  oil percentage of goldasht spring safflower cultivar, an experiment was carried out in 2012 in the agricultural research farm station of islamic azad university, roudehen branch as split plot in a completely randomized blocks design with three replications. in...

Multicomponent nanoparticles containing two or more different types of functionalities show unique physical and chemical properties, leading to significantly enhanced performance. In this study, we have developed a new one-pot method to prepare Fe/FeS nanoparticles using dithionite at room temperature. The FeS precipitates on the Fe surface are formed by the interaction between dissolved iron s...

We previously investigated the utility of μ-oxo N,N'- bis(salicylidene)ethylenediamine iron (Fe(Salen)) nanoparticles as a new anti-cancer agent for magnet-guided delivery with anti-cancer activity. Fe(Salen) nanoparticles should rapidly heat up in an alternating magnetic field (AMF), and we hypothesized that these single-drug nanoparticles would be effective for combined hyperthermia-chemother...

Polystyrene (PS) with pendant gold nanoparticles and PS-coated Fe(3)O(4) nanoparticles self-assemble into vesicle structures with PS and PS-coated Fe(3)O(4) nanoparticles in the wall and gold nanoparticles in the shell.

Low loss core-shell iron-silica nanocomposites with improved magneto-dielectric properties at radio frequencies (1 MHz-1 GHz) were successfully fabricated. A new simple method was developed to synthesize metallic iron (Fe) nanoparticles with uniform size distribution in an aqueous environment at room temperature. Citric acid and oleic acid served as surface-capping agents to control the particl...

Block copolymer micellar templates were used for the controlled synthesis of large arrays of mono-metallic (Fe, Co, Ni, Mo) and bi-metallic (Fe–Mo) nanoparticles with average diameters ranging from 1 to 4 nm and the distance between the nanoparticles ranging from 40 to 45 nm. XPS data reveal the presence of mono-metallic nanoparticles in their oxidized states. These uniform arrays of nanopartic...

Previously, iron core-gold shell nanoparticles (Fe@Au) have been shown to possess cancer-preferential cytotoxicity in oral and colorectal cancer (CRC) cells. However, CRC cell lines are less sensitive to Fe@Au treatment when compared with oral cancer cell lines. In this research, Fe@Au are found to decrease the cell viability of CRC cell lines, including Caco-2, HT-29, and SW480, through growth...
