“…Interestingly experimental data show that the graphene layers are growing inwards at the nickel-graphite interface. Carbon shells have also been engineered when Ni particles were heated in close proximity of C 60 molecules [41].…”

It has been for a long time recognized that nanoparticles are of great scientific interest as they are effectively a bridge between bulk materials and atomic structures. At first, size effects occurring in single elements have been studied. More recently, progress in chemical and physical synthesis routes permitted the preparation of more complex structures. Such structures take advantages of new adjustable parameters including stoichiometry, chemical ordering, shape and segregation opening new fields with tailored materials for biology, mechanics, optics magnetism, chemistry catalysis, solar cells and microelectronics. Among them, core/shell structures are a particular class of nanoparticles made with an inorganic core and one or several inorganic shell layer(s). In earlier work, the shell was merely used as a protective coating for the core. More recently, it has been shown that it is possible to tune the physical properties in a larger range than that of each material taken separately. The goal of the present review is to discuss the basic properties of the different types of core/shell nanoparticles including a large variety of heterostructures. We restrict ourselves on all inorganic (on inorganic/inorganic) core/shell structures. In the light of recent developments, the applications of inorganic core/shell particles are found in many fields including biology, chemistry, physics and engineering. In addition to a representative overview 2 of the properties, general concepts based on solid state physics are considered for material selection and for identifying criteria linking the core/shell structure and its resulting properties. Chemical and physical routes for the synthesis and specific methods for the study of core/shell nanoparticle are briefly discussed.

“…At present the interest in metal-carbon composites has intensively arose. This is, to be a great extent, due to the possibility of obtaining nanocrystalline metal particles encapsulated by carbonaceous materials [21][22][23][24][25][26]. Consequently, the ignition of zirconium or ZrMn 2 may be able to be prevented in air.…”

“…The one dimensional carbon nanostructures between the surface-bound silver nanoparticles grew mainly by surface diffusion which delivered the carbon atoms to nanoparticles acting as growth catalysts. 3,22 Gadd et al 23 ͑2001͒ mentioned that a relatively fast condensation ͑i.e., a relatively high cooling rate͒ favored incomplete encapsulation whereas fast condensation promoted the formation of nanotubes which grew from the solidifying metal particle. The influence of the gas flow rate on surface diffusion could affect a change in the surface diffusion activation energy, which in turn directly influenced the thermal flux on a part of surface and eventually introduced the growth of the nanotubes from silver nanoparticles ͑ϳ15 nm in diameter of agglomerates͒.…”

Using silver-carbon ambient sparks, hollow carbon nanospheres or multiwall carbon nanotubes were produced separately from carbon encapsulated silver nanoparticles ͑−1 , 400 K s −1 ͒ during relatively slow ͑−800 K s −1 ͒ or fast ͑−2 , 900 K s −1 ͒ cooling process. Different cooling processes ͑i.e., different exposures within high temperature͒ caused the formation of different carbon precipitates in the process of silver mediated graphitization: for −2 , 900 K s −1 and Ͻ−1 , 400 K s −1 , respectively, obtained tubelike and sphere ͑encapsulated and hollow͒-like carbonaceous nanostructures.
