Estuary-on-a-chip: unexpected results for the fate and transport of nanoparticles

The aim of this work is to evaluate the influence of a spatial salinity gradient, as encountered in estuaries when fresh water meets salt water, on the aggregation features of fullerene nanoparticle aggregates (nC60). To model these environmental conditions, we…

Environmental Fate Modeling of Nanoplastics in a Salinity Gradient Using a Lab-on-a-Chip: Where Does the Nanoscale Fraction of Plastic Debris Accumulate?

The aim of this study is to demonstrate how the flow and diffusion of nanoplastics through a salinity gradient (SG), as observed in mangrove swamps (MSPs), influence their aggregation pathways. These two parameters have never yet been used to evaluate…

Enhanced upconversion multicolor and white light luminescence in SiO2-coated lanthanide-doped GdVO4 hydrothermal nanocrystals

Tetragonal zircon-type codoped Yb, Ln–GdVO4 (Ln=Tm, Ho, Er) upconverting nanocrystals with square and rectangular sections were prepared through an efficient low-temperature hydrothermal synthesis. Further processing that combined annealing at 600 °C followed by coating of the surface with a uniform…

Synthesis and properties of porous ester-silica nanoparticles

Ester-silica nanoparticles (NPs) were prepared using a facile two-surfactant synthesis route in neutral medium involving silica (tetraethyl orthosilicate, TEOS) and organosilica (3-(trimethoxysilyl)propyl 5-(trimethoxysilyl)pentanoate, PMe) precursors. The ester hydrolysis generates carboxylic acid groups, which confer a strongly negative zeta potential to…

Synthesis of a Nanostructure Molecularly Imprinted Copolymer for Separation of Antifungal Bioactive Di-(2-Ethylhexyl) Phthalate from Biocontrol Fungi Metabolite

Among biocontrol fungi, Trichoderma species produce a wide range of bioactive compounds with antifungal activities. In this study, Di-(2-Ethylhexyl) Phthalate (DEHP) is identified via gas chromatography-mass spectrometry (GC-MS) device in Trichoderma atroviridae (1-3) secondary metabolites and its antifungal effectiveness is…
