TL;DR: The substitution of Fe3+ ions by Al3+ ion in the solid surface has been observed, indicating an alternative removal mechanism of arsenic in these metal hydroxides and oxyhydroxides by providing larger surface area for arsenic adsorption via retarding the crystalline formation of iron oxides.

TL;DR: In this article, the synthesis, characterization, and applications of dendrimer-encapsulated nanoparticles (DENs) are described, which are synthesized using a template approach in which metal ions are extracted into the interior of Dendrimers and then subsequently reduced chemically to yield nearly size-monodisperse particles having diameters in the 1-2 nm range.

TL;DR: The results suggest that magnetite particles and amorphous iron oxyhydroxides present in the EC products remove arsenic(III) and arsenic(V) with an efficiency of more than 99% from groundwater in a field pilot scale study.

TL;DR: In this article, an oxidation-driven structural conversion of quasi-alloy PdAu dendrimer-encapsulated nanoparticles (DENs) to a Au-core/Pd-shell configuration was presented.

TL;DR: In this article, the authors provided a detailed description of the synthesis and properties of Pt dendrimerencapsulated nanoparticles (DENs) prepared using sixth-generation, hydroxyl-terminated, poly(amidoamine) (PAMAM) dendrimers (G6-OH) and three different PtCl4 2 - /G6 -OH ratios: 55, 147, and 240.
