TL;DR: In this article, a core-shell nanocomposites (R−Au) bearing well-defined gold nanoparticles as surface atoms of variable sizes (8−55 nm) have been synthesized exploiting polystyrene-based commercial anion exchangers.

TL;DR: In this paper, sugar-assisted stable monometallic nanoparticles were synthesized by wet chemical method following a general scheme, which corroborates the shift of the absorbance peak positions and TEM analysis.

TL;DR: A new route is developed for coating Fe3O4 nanoparticles with noble metals such as gold or silver as shell for resistant to surface poisoning and yields well-defined core-shell structures of size from 18 to 30 nm.

TL;DR: The structure and composition of the bimetallic particles were characterized by UV−visible spectroscopy, transmission electron microscopy, high-resolution transmission electron microscope, electron dispersive spectrograph and X-ray photoelectron spectrogram as discussed by the authors, and they provided an elegant SERS-active substrate compared to the corresponding monometallic nanoparticles.

TL;DR: In this article, a solid phase catalyst for the reduction of 4-nitrophenol in the presence of sodium borohydride has been presented, where the electrostatic field force has been taken into consideration for the immobilization of precursor ions onto the resin beads.
