In this investigation, force field-based molecular dynamics (MD) simulations have been employed to generate detailed structural representations for a range of amorphous quaternary CaO-MgO-Al2O3-SiO2 (CMAS) and ternary CaO-Al2O3-SiO2 (CAS) glasses. Comparison the simulation results with select experimental X-ray neutron total scattering literature data reveals that MD-generated structures captur...

For many centuries, the metals are used as the antibacterial factors. Whereas, the nanoparticles are mostly heavy metal oxides, they have a high tendency to interact with biological molecules and develop the deactivation or elimination of the virus or bacteria. In the present study, the antibacterial effect of Cadmium Oxide nanoparticles on Pseudomonas Aeruginosa bacteria was analyzed which are...

introduction: biosorption of heavy metals can be an effective process for the removal of heavy metal ions from aqueous solutions. also, living lichens are known to accumulate metals across their surface. materials and methods: in this study, the biosorption of cadmium ions cd (ii) by the lichens acarospora strigata, lecanora muralis and caloplaca aurantia was investigated in aqueous solution in...

We developed a facile strategy for preparation of heteropoly metalate/graphene oxide nanocomposite as a new ion exchanger for cadmium ion removal from aqueous solution. The synthesized nanocomposite was characterized by X-ray powder diffraction (XRD), UV-Vis spectroscopy, FT-IR spectroscopy and Raman spectroscopy. Our findings indicated that the combination of heteropoly metalate nanoparticles ...

In this paper the removal of a wide range heavy metal ions from different chemical environments has been explored with use phosphate-functionalised superparamagnetic iron oxide nanoparticles (SPIONs), specifically magnetite (Fe 3 O 4 ).

The synergistic adsorption of heavy metal ions and humic acid can be very challenging. This is largely because of their competitive adsorption onto most adsorbent materials. Hierarchically structured composites containing polyethylenimine-modified magnetic mesoporous silica and graphene oxide (MMSP-GO) were here prepared to address this. Magnetic mesoporous silica microspheres were synthesized ...

the  present study was aimed  at comparing the ability of three crop plants for phytoremediation of zinc (zn) and nickel (zn) from soils. a factorial (3×2×3) experiment based on rcbd was  used to compare the treatments,  and was repeated three times. the first factor was crop type (wheat, clover and rapeseed), the second factor was heavy metal types (zinc (zn) and nickel (ni)) and the third fac...

in recent years, heavy metal contamination of rice in different parts of the world has raised concerns about its safety and provoked crisis in it's global production and trade. in iran, also some studies have reported on the heavy metal contamination of native products. however, the concentration of heavy metals in rice grain could be influenced through preparation and cooking. this study aimed...
