Core Shell Nanoparticles

Despite numerous attempts to fabricate the core–shell nanoparticles, novel, simple, and low-cost approaches are still required to produce these efficient nanosystems. In this study, we propose the synthesis of bimetallic core–shell nanoparticles of gold (AuNP) and silver (AgNP) nanostructures via a bioinspired polydopamine (PDOP) layer and their employment as a surface-enhanced Raman spectroscopy (SERS) platform. Herein, the PDOP layer was used as an interface between nanostructures as well as stabilizing and reducing agents for the deposition of silver ions onto the AuNPs. UV-vis absorption spectra and electron microscope images confirmed the deposition of the silver ions and the formation of core–shell nanoparticles. SERS activity tests indicated that both the PDOP thickness and silver deposition time are the dominant parameters that determine the SERS performances of the proposed core–shell system. In comparison to bare AuNPs, more than three times higher SERS signal intensity was obtained with an enhancement factor of 3.5 × 105.

Enhanced Selectivity

A variety of solid acid catalysts especially 12-Tungstophosphoricacid (DTP) supported on silica has been reported for the acylation of anisole, veratrole and toluene. However, the activity of this catalyst is susceptible to coke formation or poor activity. This paper reports the novelties of steam treated SiO2-DTP core-shell nanoparticles, which exhibits tremendous stability, high activity and enhanced selectivity in the liquid-phase acylation of anisole, veratrole and toluene as compared to conventional DTP supported on silica.

Proper Analysis

A new mechanical dry process able to develop nanoparticles coated with polymeric material is proposed. An opportunely developed pilot ball milling apparatus permitted to catch-up significant process parameters that are here reported. A proper analysis of the obtained parameters permitted to individuate optimized milling conditions and to prepare a magnetite/albumin core/shell nanocomposite, material with a potential wide spread of applications in biomedical fields. The obtained powder consists in particles having a diameter of about 45 nm and exhibits a high morphological homogeneity. The proposed method is facile, low cost, solvent free and is applicable to the development of a broad range of multifunctional composites for biomedical applications.
