There are reports that nano-sized zero-valent iron (Fe0) exhibits greater reactivity than micro-sized particles of Fe0, and it has been suggested that the higher reactivity of nano-Fe0 may impart advantages for groundwater remediation or other environmental applications. However, most of these reports are preliminary in that they leave a host of potentially significant (and often challenging ...

The method still follows the wet [31] chemical process but vermiculite is used to stabilize the nanoparticles. Hundakova also studied the stability of silver and copper …
This paper shows effective removal of copper from water and industrial wastewater by modified magnetic nanoparticle with benzotriazole as an efficient adsorbent. The method is fast, simple, cheap, effective and safe for treatment of copper polluted waters. Non-modified magnetic iron oxide nanoparticles (MIONPs) can adsorb up to 49.6% of 50 ng ml-1 of Cu (ΙΙ) ions from polluted water, but ...
In this study, synthesis of copper nanoparticles was performed using organoclay as a support to stabilize the nanoparticles. Organoclay amount was gradually increased, which had an effect on the morphology of the resultant nanoparticles. Low amount of organoclay added resulted in larger and agglomerated copper nanoparticles whereas increased amount of organoclay gave smaller sized nanoparticles.
Abstract. Adsorption heat transformation (AHT) is one of the challenging technical approaches for supporting the world community initiatives to alleviate or reverse the gravity of the problems arising from CO 2 emissions and global warming. The key tool for enhancement of the AHT efficiency and power is a harmonization of adsorbent properties with working conditions of the AHT cycles.
Vertically aligned carbon nanotube arrays (VANTAs) are a unique microstructure consisting of carbon nanotubes oriented along their longitudinal axis normal to a substrate surface. These VANTAs effectively preserve and often accentuate the unique anisotropic properties of individual carbon nanotubes and possess a morphology that may be precisely controlled.
The XRD spectra are presented in Fig. 1a and b. As shown in Fig. 1a, the raw vermiculite presented a characteristic diffraction peak at around 5.92° (d 001), corresponding to a typical basal spacing of 1.49 nm.Compared to the raw vermiculite, there was a weak reflection at about 2θ = 4.85° in the XRD pattern of AVT, which suggested that a small proportion of the APTES molecules has been ...
