Therefore, it has become an important nanomaterial in biomedicine. The Role of Gold Nanoparticles Gold nanoparticles alias AuNPs and nano gold, their diameters are 1~100 nm. ...
In the electron microscope measurement, it should be noted that: 1)The measured particle size may be the size of the aggregates, so when preparing the nanoparticle SEM sample, it should be fully dispersed; 2) The measurement result is not statistical because the amount of the electron microscope sample is very small. ...
A new, simple and rapid method for solid phase extraction and preconcentration of trace amounts of cadmium ions using 2-mercaptobenzothiazole/sodium dodecyl sulfate immobilized on magnetite nanoparticles (MBT-SDS-MNPs) was proposed. The method is based on the extraction of cadmium ions via complexation with MBT immobilized on SDS-coated MNPs and their determination by flame ...
This study reports on synthesis of a new nanoadsorbent for efficient Cu(II) and Pb(II) ions removal from water samples. In this regard, magnetite nanoparticles have been modified with 2,4-dinitrophenylhydrazine. ...
This study investigated the applicability of magnetite Fe3O4 nanoparticles coated with chitosan (CMNs) for the removal of some toxic heavy metals from simulated wastewater. ...
We report a simple method involving mechanical attrition followed by hot press sintering to fabricate tablet samples consisting of silver nanoparticles (Ag NPs) dispersed in luminescent silicon nanocrystal (Si NC) matrix. ...
Thermoluminescence and photoluminescence are observed in nanoparticle and bulk NaMgF3:Mn2+ samples. The activation energies for the two main peaks in the TL data are similar for nanoparticle and bulk samples and they are nearly independent of Mn2+ concentration. ...
Aerobically digested sludge and waste activated sludge sourced from the Hunter Valley, NSW, Australia, were tested with titanium dioxide nanoparticles. The sludge samples were dosed with the nanoparticles in an attempt to adsorb a component of the charged biopolymer surfactants present naturally in sludge. ...
To this aim, we present a new route to modify some spectroscopic properties of RE ions in silica–based fibres based on the incorporation of erbium ions in amorphous dielectric nanoparticles, grown in–situ in fibre preforms. By adding alkaline earth elements, in low concentration into silica, one can obtain a glass with an immiscibility gap. ...
Increased interest in research and applications of nanoparticles requires rapid qualitative and quantitative analysis of nanoparticle samples. The development of the NanoLog spectrofluorometer and associated Nanosizer software takes advantage of nanoparticles’ fluorescence in the near-IR, and allows researchers to rapidly ...
