Multicompartment Core/Shell Microgels

Journal of the American Chemical Society, 2010
Multiresponsive poly(N-isopropylacrylamide-co-acrylic acid) (pNIPAm-AAc) microgels containing mechanically and thermodynamically decoupled poly(N-isopropylmethacrylamide) (pNIPMAm) cores have been prepared. To achieve this structure, pNIPMAm microgels were used as templates in the synthesis of an N,N'-(1,2-dihydroxyethylene)bisacrylamide (DHEA) cross ...

Core/Shell Semiconductor Nanocrystals

Small, 2009
AbstractColloidal core/shell nanocrystals contain at least two semiconductor materials in an onionlike structure. The possibility to tune the basic optical properties of the core nanocrystals, for example, their fluorescence wavelength, quantum yield, and lifetime, by growing an epitaxial‐type shell of another semiconductor has fueled significant ...

Core–Shell Nanostructured Catalysts

Accounts of Chemical Research, 2012
Novel nanotechnologies have allowed great improvements in the syn-thesis of catalysts with well-controlled size, shape, and surface properties. Transition metal nanostructures with specific sizes and shapes, for instance, have shown great promise as catalysts with high selectivities and relative ease of recycling.

Magic Polyicosahedral Core-Shell Clusters

Physical Review Letters, 2004
A new family of magic cluster structures is found by genetic global optimization, whose results are confirmed by density functional calculations. These clusters are Ag-Ni and Ag-Cu nanoparticles with an inner Ni or Cu core and an Ag external shell, as experimentally observed for Ag-Ni, and present a polyicosahedral character.

Core-Shell Nanoparticles

Imaging & Microscopy, 2006
A method to produce nanoparticles with core-shell structure, having crystalline Ni3Si core and amorphous Si(O) shell is reported. The core-shell nanoparticles are extracted from a two phase metallic alloys by selective phase separation using electrochemical dissolution technique.

Stability of core–shell magnetite nanoparticles

Colloids and Surfaces B: Biointerfaces, 2014
In the paper, we present three different types of magnetite nanoparticles which were prepared from co-percipitation of iron (II) and (III) chlorides in aqueous solution with and without SiO2 and from thermal decomposition of iron (III) acetylacetonate in nonaqeous solutions.

Multifunctional composite core–shell nanoparticles

Nanoscale, 2011
In this review paper, the state-of-the-art knowledge of the core-shell multifunctional nanoparticles (MNPs), especially with unique physiochemical properties, is presented. The synthesis methods were summarized from the aspects of both the advantages and the demerits.

Layered and core-shell uniaxial absorbers

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
We derive periodic multilayer absorbers with effective uniaxial properties similar to a perfectly matched layer (PML). This approximate representation of a PML is based on effective medium theory, and we call it an effective medium PML (EM-PML). We also show that cylindrical core-shell nanostructures derived from flat multilayers also exhibit very good

Si–SiC core–shell nanowires

Journal of Crystal Growth, 2013
Abstract The objective of this study is to grow Si–SiC core–shell nanowires (NWs) for bio-nano-sensors. The idea is to benefit from the electronic transport into the Si core NW and from the biocompatibility of the SiC shell all around the Si NW. Silicon nanowires (NWs) have been first obtained by a top-down approach.
