TL;DR: Pd-Pt bimetallic nanodendrites consisting of a dense array of Pt branches on a Pd core by reducing K2PtCl4 with L-ascorbic acid in the presence of uniform Pd nanocrystal seeds in an aqueous solution showed relatively large surface areas and particularly active facets toward the oxygen reduction reaction (ORR), the rate-determining step in a proton-exchange membrane fuel cell.

TL;DR: In this article, a unified overview of matrix nanocomposites is presented underlining the need for these materials, their processing methods and some recent results on structure, properties and potential applications, perspectives including need for such materials in future space mission and other interesting applications together with market and safety aspects.

TL;DR: A simple, one-pot method that generates dimers of silver nanospheres in one step without any additional assembly steps that provides a well-defined system for studying the hot spot phenomenon in surface-enhanced Raman scattering (SERS).

TL;DR: In this article, the shape control of Pd nanocrystals with well-controlled shapes in aqueous solutions is discussed. But the shape of the final shape taken by a nanocrystal is determined by the twin structures of seeds and the growth rates of different crystallographic facets.

TL;DR: It was found that Br(-) ions played an important role in initiating, facilitating, and directing the replacement reaction, and the site-selective galvanic replacement resulted in the formation of Pd-Pt bimetallic nanocrystals with a concave structure.
