In this study, Cu, Ag, and Fe nanoparticles (NPs) are used in shampoo, hand washing liquid (HWL) and dish washing liquid (DWL) instead of the conventional synthetic preservatives such as isothiazolinones; since the latter often act as potent sensitizers that leads to development of allergic contact dermatitis. The above NPs are considerably effective against Escherichia coli and Staphylococcus ...

B4C and its composites with TiB2 as second phase continues to be extensively used as the preferred ceramic material in military applications as armor systems for absorbing and dissipating kinetic energy from high velocity projectiles. It also exhibits a high melting point (2427 °C), and high neutron absorption cross section. Pressureless sintering of the B 4C-nanoTiB2 nanocomposite using small ...

In this research the composition of polyurethane closed cell (PUCC) with two different concentrations of SiO2 nanoparticles (1.0 and 2.0 wt%) have been prepared. Optical microscopy and SEM imaging, watering uptake, FTIR and Raman spectroscopy of the synthesized samples were carried out. The optical microscopy imaging of samples showed differences in the appearance of matrix produ...

The development of a theranostic nanoplatform based on rotavirus structural protein VP4-coated Fe(3)O(4) nanoparticles (NPs) for dual modality magnetic resonance/fluorescence cellular imaging and drug delivery is reported. VP4 protein was obtained from Escherichia coli approach, and then chemically conjugated to Fe(3)O(4) NPs premodified with meso-2,3-dimercaptosuccinnic acid (DMSA) in the pres...

Magnetic iron oxide nanoparticles (Fe-NPs) can be exploited in biomedicine as agents for magnetic fluid hyperthermia (MFH) treatments and as contrast enhancers in magnetic resonance imaging. New, oleate-covered, iron oxide particles have been prepared either by co-precipitation or thermal decomposition methods and incorporated into poly(lactic-co-glycolic acid) nanoparticles (PLGA-Fe-NPs) to im...

Although it is frequently hypothesized that surface (like surface charge) and physical characteristics (like particle size) play important roles in cellular interactions of nanoparticles (NPs), a systematic study probing this issue is missing. Hence, a comparative cytotoxicity study, quantifying nine different cellular endpoints, was performed with a broad series of monodisperse, well character...

Nanomaterials are used in practically every aspect of modern life, including agriculture. The aim of this study was to evaluate the effectiveness of iron oxide nanoparticles (Fe2O3 NPs) as a fertilizer to replace traditional Fe fertilizers, which have various shortcomings. The effects of the Fe2O3 NPs and a chelated-Fe fertilizer (ethylenediaminetetraacetic acid-Fe; EDTA-Fe) fertilizer on the g...

Iron excess of the Earth. The Fe/Mg ratio of the whole Earth is at least 10% higher than the Fe/Mg ratio of the average solar system. Improved estimates of the chemical composition of the primitive upper mantle yield an MgO content of 36.33 ± 0.4 wt% [1], which transforms into a whole Earth Mg content of 14.90 wt%, assuming 32% for the mass of the core and that the core is Mg-free. The FeO cont...

In this current research, we described an enhanced power conversion efficiency of dye sensitized solar cell (DSSC) and fabricated through Few Layered Graphene (FLG)/CuO nanocomposite synthesized by ultrasonic assisted synthesis (UAS) by varying of FLG (1, 2 and 3 wt%) ratio. The FLG/CuOnanocomposites characteristic features understood through various microscopic techniques such as FE-SEM and HR...
