Highly stable monodispersed nano Cu hydrosols were facilely prepared by an aqueous chemical reduction method through selecting copper hydroxide (Cu(OH)2) as the copper precursor, poly(acrylic acid) (PAA) and ethanol amine (EA) as the complexing agents, and hydrazine hydrate as the reducing agent. The size of the obtained Cu colloidal nanoparticles was controlled from 0.96 to 26.26 nm by adjusti...

The study of colloidal dispersions of micro-nano sized particles in a liquid is of great interest for industrial processes and technological applications. The understanding of the microstructure and fundamental properties of this kind of systems at microscopic level is also useful for biological and biomedical applications. However, a colloidal suspension must be placed somewhere and the dynami...

Scanning electrochemical cell microscopy (SECCM) is a scanning-droplet-based technique that allows fluxes and/or interfacial reactivity to be measured and visualized with high spatiotemporal resolution. This minireview spotlights the use of SECCM for studying electrochemistry (nano)particles, highlighting recent works spanning multiple timescales (i.e., microseconds seconds) lengthscales nanome...

We report the colloidal synthesis of bismuth chalcohalide nanocrystals, which adopt a hexagonal phase that we describe with Bi13S18X2 (in X = Br and I) structure. Such model structure displays columns Bi atoms form dimers subvalent (formally Bi24+), here ascribe to Peierls-type distortions. suggest Bi24+ are at origin anomalously low band gap this material, lowest energy electronic transition s...

The aqueous extract of Ocimum basilicum leaves and zinc salts (zinc sulphate) was used as precursors in this investigation to create oxide nanoparticles. ultraviolet-visible spectroscopy, scanning electron microscopy, Dynamic light scattering (DLS) were characterize the produced (SEM), Energy-dispersive X-ray analysis (EDX), Because UV-Vis spectra exhibit absorption peaks 350 nm range. DLS prov...
