Nanomaterials properties

Unfortunately, current S3mthesis techniques, such as chemical vapor deposition, arc discharge, laser ablation, or detonation, typically lead to a mixture of various nanostructures, amorphous carbon, and catalyst particles rather than a particular nanostructure with defined properties, thus limiting the number of potential applications [1]. Even if pure materials were available, the size-dependence of most nanomaterial properties requires a high structural selectivity. In order to fully exploit the great potential of carbon nanostmctures, one needs to provide purification procedures that allow for a selective separation of carbon nanostructures, and methods which enable size control and surface functionalization.

Physical Factors Which Determine the Nanomaterial Properties... 

The aforementioned factors influence on the observable properties of nanomaterials. In particular, the distribution of the grain sizes usually leads to additional spatial inhomogeneity of nanomaterial properties. In radio-, optical and dielectric spectroscopy this yields so-called inhomogeneous line broadening [12] and the decrease of permittivity.

Thus, the liquid objects, which have if only one dimension of nanoscale size, consist of second liquid. This conclusion is obtained from theoretical considerations and is of great ap>plied significance. It is shown that the second liquid conception could throw light upon the following problems 1) the cause of uniquity of solid nanomaterial properties 2) the ion-induced nucleation in atmosphere 3) some unusual properties of liquid water in nanocavities (particularly, in the cells of living organisms). Ap>parently, this list might be continued.
