Gold nanorods coated with a uniform titanium dioxide nanoshell have been prepared and used as glucose-oxidase surrogates. Remarkably, this core-shell photocatalytic nanostructure has been able to induce complete oxidation of glucose at near room temperature (32-34 °C) in a wide range of pH values with the aid of a near-infrared (NIR) irradiation source. In contrast, the uncoated gold nanorods e...

TiO2-SiO2 core-shell particles include of monodisperse silica core and nanostructured titania shell were synthesized by a multi-step coating process. The monodisperse silica spheres were synthesized by Stöber method and titania shell was obtained of a colloidal sol prepared by a hydrolysis–condensation reaction. The titania sol was deposited on monodisperse silica spheres by a multi-step coatin...

Core-shell structured electrorheological (ER) and magnetorheological (MR) particles have attracted increasing interest owing to their outstanding field-responsive properties, including morphology, chemical and dispersion stability, and rheological characteristics of shear stress and yield stress. This study covers recent progress in the preparation of core-shell structured materials as well as ...

SiO2/ZnS core/shell nanostructures have been synthesized at room temperature by a simple wet chemical method. The prepared materials are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy (IR), UV–vis spectroscopic and transmission electron microscopy (TEM) studies. X-ray diffraction pattern exhibits peaks correspond to the cubic phase of ZnS. Th...

Recently, the synthesis of low-toxic quantum dots (QDs) and their application in biomedicine have attracted considerable attention. ZnSe nanocrystals doped with Mn ions which do not contain any Class A element (Cd, Pb, and Hg) can be used as a new generation of luminescent nanocrystals due to their strong dopant emission. In 2001, Norris et al. presented an organometallic synthetic route for th...

Localized surface plasmon resonance (LSPR) and electrochemistry measurements connecting to core-shell structure nanoparticle are successfully exploited in a simultaneous detectable scheme. In this work, the surface plasmon band characterizations of this nanostructure type are initially examined by controlling the core size of the silica nanoparticle and shell thickness of the deposited gold. Th...

Introduction: Nanoparticles have several exciting applications in various fields of biomedicine. It has been found that among different classes of nanoparticles core/shell is most promising for field of nano-medical imaging and therapy due to their distinct advantages. The core/shell type nanoparticles can be generally comprising of two nanoparticles one act as a core (inner ma...

The effect of substituting 0.01 or 0.02 at.% Er for Sc in an Al–0.06 Zr–0.06 Sc at.% alloy was studied to develop cost-effective high-temperature aluminum alloys for aerospace and automotive applications. Spheroidal, coherent, L12-ordered Al3(Sc, Zr, Er) precipitates with a structure consisting of an Er-enriched core surrounded by a Sc-enriched inner shell and a Zr-enriched outer shell (core/do...
