Study of aggregation of gold nanoparticles in chitosan
(2018)
In this work it is reported the synthesis of gold nanoparticles supported in situ in chitosan by solvated metal atom dispersion technique in order to study the inclusion of Au nanoparticles in the biopolymer matrix. To ...
Dependence of the broad frequency dielectric spectra of colloidal polystyrene particle suspensions on the difference between the counterion and co-ion diffusion coefficients
(Academic Press Inc Elsevier Science, 2006-12)
Dielectric properties of four suspensions of spherical polystyrene particles were measured at 25 ◦ C over a broad frequency range extending from 100 Hz to 10 MHz, using a HP 4192 A Impedance Analyzer. The instrument was ...
Zeta Potential and Colloidal Stability Predictions for Inorganic Nanoparticle Dispersions: Effects of Experimental Conditions and Electrokinetic Models on the Interpretation of Results
(2021-01-01)
In this work, a set of experimental electrophoretic mobility (μe) data was used to show how inappropriate selection of the electrokinetic model used to calculate the zeta potential (ζ-potential) can compromise the ...
Colloidal Stability by Adsorption of Ni2+ or Fe3+ Cations on Hairy Latex Particles
(Taylor & Francis IncPhiladelphiaEUA, 2012)
Study of the colloidal stability and optical properties of sunscreen creams
(2019-01-01)
Sunscreen formulations containing inorganic/organic filters or mixture of them were synthesized by oil/water dispersion. The viscosity measurements show that sunscreen formulations are time-dependent non-Newtonian fluids. ...
Colloid Transport in Porous Media: A Review of Classical Mechanisms and Emerging Topics
(Springer, 2019-03)
To celebrate the tenth anniversary of InterPore, we present an interdisciplinary review of colloid transport through porous media. This review aims to explore both classical colloid transport and topics that fall outside ...
Synthesis and aggregation study of tin nanoparticles and colloids obtained by chemical liquid deposition
(2009)
Tin colloids (Sn-Colls) and nanoparticles were synthesized by a chemical liquid deposition method (CLD). Sn0 was evaporated and codeposited with acetone, 2-propanol, and tetrahydrofurane vapors at 77 K to obtain colloidal ...
SYNTHESIS OF IRON AND IRON-MANGANESE COLLOIDS AND NANOPARTICLES USING ORGANIC SOLVENTS
(Sociedad Chilena de Química, 2005)
Effect of Nanoclustering and Dipolar Interactions in Heat Generation for Magnetic Hyperthermia
(American Chemical Society, 2016-02)
Biomedical magnetic colloids commonly used in magnetic hyperthermia experiments often display a bidisperse structure, i.e., are composed of stable nanoclusters coexisting with well-dispersed nanoparticles. However, the ...
