IN studying the absorption spectra of the vapours of the homologous aldehydes 1 a band spectrum was observed in butyric and iso-butyric aldehydes, which was ultimately discovered to be due to benzene.

Iron is one of the main elements found in the Earth's inner core, which is characterized by extremely high temperatures and ...

The process begins with the absorption of X-ray photons by atoms in the material, leading to the ejection of photoelectrons. By analyzing the energy spectrum of these photoelectrons, information about ...

X-ray Photoelectron Spectroscopy (XPS)is a highly sensitive technique for identifying and quantifying the chemical states of elements on the outermost surface of a solid. It is especially useful for ...

The Helsinki Center for X-ray Spectroscopy is a unique research and education infrastructure serving users from both academia and industry in their leading-edge research, development and innovation.

A study appearing in Proceedings of the National Academy of Sciences introduces a trimetallic catalyst—including nickel (Ni), ...

Energy Dispersive X-Ray Spectroscopy (EDS) is a microanalysis method used in addition to scanning electron microscopy (SEM). EDS provides chemical information by detecting x-rays released from a ...
