Onion-like carbon-encapsulated Co, Ni, and Fe magnetic nanoparticles with low cytotoxicity synthesized by a pulsed plasma in a liquid

A review of plasma–liquid interactions for nanomaterial synthesis

“…[191], we correct it as Oe in this review.). In addition, the results of human lung epithelial A549 cells exposure to Fe@C, Co@C and Ni@C NPs showed a low cytotoxicity of these NPs [190]. The high magnetic properties and low cytotoxicity renders these NPs possible manipulation in biomedicine application.…”

Strain Mechanisms in Lead-Free Ferroelectrics for Actuators

“…285,468 With the advent of nanotechnology, there has also been a continuous increase in organic and inorganic core-shell nanoparticle discoveries with exceptional properties. 8 This gave rise to the discovery of several types of core-shell microstructures, such as spherical 256,284,285,468 , hexagonal 469,470 , multiple cores within a single shell 471,472 , onion-like 473,474 , movable core within shell 475,476 , and 2-D structures such as rods [477][478][479] , among others. A general notation is described here in an attempt to standardize the nomenclature used to define core-shell microstructures.…”

“…The region that surrounds the core is defined as the shell. It is possible, for example in "onion/matryoshka-like" structures 473,474 , that several constituents can be simultaneously considered as both a core and a shell.…”

“…There is no need to repeat n and k indexes in case all inner constituents present the same number of mirror planes such as for instance in conventional "onion/matryoshka-like" structures. 473,474 Based on these considerations, the generalized nomenclature for core-shell geometries proposed is exemplified in Figure 8.1. Examples of the core-shell geometries found in literature are also given.…”

Photothermal cancer therapy using graphitic carbon–coated magnetic particles prepared by one-pot synthesis

“…The strategies for synthesizing combined composites of magnetic particles encapsulated with GC often involve complicated preparation processes. 15 To date, several methods have been used for the synthesis of GC-encapsulated magnetic metal nanoparticles, including chemical vapor deposition, 16 arc discharge, 17 spray pyrolysis, 18 plasma methods, 19 and one-pot synthesis in closed cells. 20 One-pot synthesis is one such strategy that has been developed to generate new classes of metal crystals in carbonaceous matter.…”
