Aqueous Nanofluids based on Thioglycolic acid-coated copper sulfide nanoparticles for heat-exchange applications
(Elsevier B.V., 2020-09-01)
We report the one-pot synthesis of an aqueous nanofluid (NF) with improved thermal conductivity and with high colloidal stability. The thermal conductivity showed an increase of 38% (relative to the base fluid) for NF with ...
Synthesis, characterization and properties of magnetic colloids supported on chitosan
(2011)
This work proposes the synthesis, characterization and investigation of the stabilization capabilities of chitosan doped with magnetic nanoparticles. Nanoparticles of Fe, Co, Co(II,III) oxide, Ni and Ni/Ag mixture in ...
Molecular dynamics characterization of silver colloidal interfaces for SERS applications. Gallic acid test
(2018)
One of the most useful applications of silver colloidal solutions is in surface-enhanced Raman spectroscopy (SERS), because the amplification factor of about 10(6) allows the vibrational study and detection of highly diluted ...
Synthesis of highly stable Fe/FeOx@citrate colloids with strong magnetic response by mechanochemistry and coprecipitation for biomedical and environmental applications
(Elsevier Science, 2020-03)
We present a simple, scalable, and low-cost route for producing aqueous colloids of nanometer size Fe cores coated with iron oxide and stabilized with sodium citrate. The Fe cores were obtained by mechanosynthesis by means ...

PEGylation of SPIONs by polycondensation reactions: A new strategy to improve colloidal stability in biological media
(2013-07-12)
In this study, we report on a new route of PEGylation of superparamagnetic iron oxide nanoparticles (SPIONs) by polycondensation reaction with carboxylate groups. Structural and magnetic characterizations were performed ...
