SYNTHESIS AND MORPHOLOGY OF CO/AUBIMETAL NANOPARTICLES WITH CORE-SHELL STRUCTURE

Вестник Кемеровского государственного университета, 2014
Bimetal systems of Co/Au nanoparticles with core-shell structure were synthesized by the reduction – electrochemical replacement reaction in aqueous solutions. The core-shell structure is proved by spectroscopy in the visible area and by SAXS.

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...

Physical Insights Into Cylindrical Illusion Device With Isotropic and Homogeneous Materials

IEEE Access, 2020
The cylindrical illusion device with isotropic and homogeneous materials is studied deeply based on the Mie scattering theory. The formula for illusion of core-shell structure is derived in the quasistatic approximation.

The Dynamics of Collapsing Monopoles and Regular Black Holes [PDF]

, 2000
We study the formation and stability of regular black holes by employing a thin shell approximation to the dynamics of collapsing magnetic monopoles. The core deSitter region of the monopole is matched across the shell to a Reissner-Nordstrom exterior ...

Modelling exchange bias in core/shell nanoparticles

, 2007
We present an atomistic model of a single nanoparticle with core/shell structure that takes into account its lattice strucutre and spherical geometry, and in which the values of microscopic parameters such as anisotropy and exchange constants can be ...

Enhancing Optoelectronic Properties in Phthalocyanine‐Based SURMOFs: Synthesis of ABAB Linkers by Avoiding Statistical Condensation with Tailored Building Blocks

Advanced Functional Materials, EarlyView.
A novel phthalocyanine (PC)‐based metal–organic framework (MOFs) is synthesized using ditopic PC linkers obtained through regioselective statistical condensation. The resulting MOF exhibits significant improvements in electronic absorption, thereby enhancing the material's performance in light harvesting and energy conversion.
