Microstructures of both as-quenched and intercritical-annealed medium-Mn steel were investigated by transmission electron microscopy to acquire a better understanding ?–? ?–?? martensitic transformations. The orientation relationships among each phases determined as (1¯10)??//(0001)?,[111]??//[112¯0]? for the case sample, (1¯10)??//(1¯11)?//(0001)?,[111]??//[110]?//[112¯0]? respectively. In add...

The main aim of this study was to prepare apple pomace polyphenolic extract (APPE- referred to as a core) loaded into biodegradable and commercially available natural polymer such as maltodextrin (MD-referred to as a shell). The polymer coating potentially improves its low stability and bioavailability and also directs the control release of the encapsulated material. The MD-nanoparticles (NPs)...

In this study, the electrocatalytic activity of the Co@Pt core-shell nanoparticles toward the ethanol oxidation reaction has been investigated by cyclic voltammetry and chronoamperometry in acidic and alkaline media in details. The physicochemical data obtained in alkaline solution are compared to those in acidic solution. The obtained results demonstrate that while in the both media Co@Pt core...

Polycrystalline iron phosphide coated iron oxide and hollow iron phosphide nanoparticles were synthesized by sonichemistry. Structure analysis indicated that the diameters of these nanoparticles were less than 14 nm, and the core–shell and hollow nanoparticles are Fe3O4–FeP and FeP, respectively. Magnetic measurement demonstrated that both the core–shell Fe3O4–FeP and hollow FeP nanoparticles e...

This paper describes a simple and environmentally-friendly approach that allowed for the facile synthesis of a gadolinium-based core/shell/shell nanotube structure with a set of lanthanide ions incorporated into separated layers. In addition, by the rational design of a core/shell structure we systematically investigated the luminescence properties of different lanthanide ions in NaGdF4 host, a...

Nanocrystalline SnO2 core and ZnO as well as SiO2 shells coated core shell nanoparticles have been successfully synthesized by co-precipitation method. The as prepared samples were characterized by X-ray diffraction, FTIR, UV-Visible absorption, PL, FESEM, HRTEM with EDX measurements. The X-ray analysis showed that the obtained SnO2 core with tetragonal rutile crystalline structure and the shel...
