Synthesis and characterization of functionalized core–shell γFe2O3–SiO2 nanoparticles

“…A minimal amount of ammonia was then necessary to obtain a complete coating of particles and a good dispersion of core-shell particles. Nevertheless, a larger amount of ammonia led to the formation of maghemite free silica particles as a result of rapid hydrolysis of TEOS [20]. An ammonia concentration of 0.12 mol/L appeared to be a good compromise.…”

“…Silica shell was formed by the condensation of tetraethoxysilane (TEOS) compound in a mixture of ethanol and water [20]. The presence of citrate allows increasing organosilane affinity for particle surface.…”

Nanofabrication of Metal Oxide Patterns Using Self-Assembled Monolayers

“…Especially, 2D patterns of tin oxide nano-structures on flexible polymer films are required for light-weight flexible sensors and solar cells. 2D patterning of nanomaterials 119,120 such as metal oxides 33,54,63,75,121,122 , Au clusters 123 , Pt nanoparticles 124 , organic monolayers 125 , bio molecular layers 126 , DNA 127 , etc. is expected to lead to a large step forward in materials science research and the development of new devices.…”

Monitoring the On-line Concentration and Separation of Gold Nanoparticles Using the Reversed Electrode Polarity Stacking Mode and Micellar Electrokinetic Chromatography

“…26,27 During the REPSM process, switching back to the normal polarity at the right moment is very important, because any back-flush during the stacking period may cause the loss of analytes. [26][27][28] Ding et al revealed that injecting a small plug of buffer after the sample could be used to avoid the possibility of losing any analytes. 28 Therefore, I investigated whether the introduction of a buffer plug after injecting the samples would affect the on-line concentration and separation of the Au NP samples.…”
