Engineering of silica-supported platinum catalysts with hierarchical porosity combining latex synthesis, sonochemistry and sol-gel process

A novel catalyst preparation procedure is proposed in order to enhance the noble metal distribution at low loadings, while controlling the hierarchical porosity of the support material. Thus, a silica-supported platinum catalyst with hierarchical porosity was prepared using a combination…

Use of Zebrafish Larvae as a Multi-Endpoint Platform to Characterize the Toxicity Profile of Silica Nanoparticles

Nanomaterials are being extensively produced and applied in society. Human and environmental exposures are, therefore, inevitable and so increased attention is being given to nanotoxicity. While silica nanoparticles (NP) are one of the top five nanomaterials found in consumer and…

Viscosity and stability analysis of hitec salt-based alumina nanofluids

Nanofluids based on molten salts have been recently studied thanks to the increase in some thermophysical properties compared to the base salt. Despite the interest shown in such material, information on its stability over time and viscosity is lacking, especially…

Engineering of NIR fluorescent PEGylated poly(RGD) proteinoid polymers and nanoparticles for drug delivery applications in chicken embryo and mouse models

Proteinoids are non-toxic biodegradable polymers based on thermal step-growth polymerization of natural or synthetic amino acids. Hollow proteinoid nanoparticles (NPs) may then be formed via a self-assembly process of the proteinoid polymers in an aqueous solution. (230 characters)

Engineering of new methylstyrene farmin vinylic monomer and crosslinked poly(methylstyrene farmin) nanoparticles of narrow size distribution for antibacterial and antibiofilm applications

The vinylic monomer methylstyrene farmin (MSF) was synthesized by interacting p-chloromethyl styrene with farmin in basic distilled water. Crosslinked poly(methyl styrene farmin) nanoparticles (PMSF NPs) were then synthesized by dispersion co-polymerization of the MSF monomer with the crosslinking monomer tetra(ethylene…
