term: carbon nanomaterials

Determination:

a collective term denoting carbon-based small-scale structures or nanostructured materials.

Description:

Carbon nanomaterials include fullerenes (see also fullerite) and their derivatives (see also fulleride, endohedral fullerene), carbon nanotubes, carbon nanofibres, nanodiamonds and graphenes (see also graphane).

Carbon nanomaterials are often used as filling compounds in composites, the most widely known of which are composite materials with a polymer matrix.

X-ray absorption fine structure

Determination:

Oscillations observed in x-ray absorption spectra of. Often XAFS implies XAFS-spectroscopy.

Description:

In the modern sense, the term XAFS combines the notations of several X-ray absorption ranges close to absorption discontinuity caused by the photoelectric effect: the XANES region, sometimes referred to as the NEXAFS (near edge X-ray absorption fine structure) with ...
