“…In a high intensity discharge (HID) plasma transitions between energy levels could be determined by a series of phenomena like: atom collisions leading to the excitation of one species to a higher energy level; collisions of an excited species with another particle, leading to radiationless relaxation; excitation by collision with electrons; de-excitation with the transfer of energy to an electron; excitation of atoms or ions by absorption of radiation; de-excitation of atoms or ions by spontaneous or stimulated emission [11].…”

Time variation of optical emission lines for Hg, and other elements detected in a mercury HID lamp before and during X-ray irradiation were analyzed. Various irradiation conditions are causing differences in time dependencies of all Hg spectral line intensities (including that of 253.73 nm resonance line not completely self-absorbed). The X-ray optical depths are smaller in the case of Hg gas compared with burner wall glass. The free electrons generated during X-ray exposure (photoelectrons, Auger electrons) contribute to changes in plasma characteristics (e.g. plasma temperature, density, etc.) in transitory regime. In quasi-stable regime there are practically no differences between electron temperatures for normal and irradiated lamp. A qualitative explanation in the framework of Beer-Lambert law is given.

Melanins as Sustainable Resources for Advanced Biotechnological Applications

et al. 2020

View full text Add to dashboard Cite

Melanins are a class of biopolymers that are widespread in nature and have diverse origins, chemical compositions, and functions. Their chemical, electrical, optical, and paramagnetic properties offer opportunities for applications in materials science, particularly for medical and technical uses. This review focuses on the application of analytical techniques to study melanins in multidisciplinary contexts with a view to their use as sustainable resources for advanced biotechnological applications, and how these may facilitate the achievement of the United Nations Sustainable Development Goals.
