Due to high molecular absorption, THz signals experience severe path loss over ... To overcome this issue, in this paper, we propose a metapath-based heterogeneous graph-transformer network ...

In the terahertz spectrum of Venus, an absorption line appears that is characteristic of atomic oxygen. The strength and shape of the absorption signal is a measure of the amount of atomic oxygen and ...

Atomic absorption spectroscopy (AAS) is used for the detection and analysis of specific elements in liquid or solid samples. Its working principle is that atoms and ions can selectively absorb ...

Credit: Technology Networks.8 UV-Vis spectroscopy analysis, absorption spectrum and absorbance units UV-Vis spectroscopy information may be presented as a graph of absorbance, optical density or ...

Graphene is a single-atom-thick carbon sheet discovered in 2004. The crucial question during graphene synthesis is, "How do I know that the material I'm making is actually single-atom thick?" Because ...

Flame Atomic Absorption Spectroscopy (FAAS) is a very popular analytical technique that has been employed by researchers for the elemental analysis of trace metals in a variety of samples. How does it ...
