Antigua fundición de plomo en el sitio inca de Curamba, departamento de Apurímac, Perú
Bulletin de l'Institut Français d'Études Andines, 2012 Since 16th century, the Inca site of Curamba, Department of Apurímac, in southern Peru, has been interpreted as a metallurgical center for processing silver ore. However, there was no physical evidence such as fragments, or other indicators of the use of

Evolution of electron temperature in inductively coupled plasma [PDF]
, 2017 It is generally recognized that the electron temperature T_e either remains constant or decreases slightly with plasma power (plasma density). This trend can be simply verified using a single-step or multi-step fluid global model.

Analysis of De-Laval nozzle designs employed for plasma figuring of surfaces [PDF]
, 2016 Plasma figuring is a dwell time fabrication process that uses a locally delivered chemical reaction through means of an inductively coupled plasma (ICP) torch to correct surface figure errors. This paper presents two investigations for a high temperature

Inductively coupled plasma mass spectrometry
Nature Reviews Methods Primers, 2023 Inductively coupled plasma mass spectrometry (ICP-MS) combines plasma chemistry, which produces singly charged elemental ions, with mass spectrometric detection. Unlike other mass spectrometry ionization sources, the ICP can efficiently handle liquid, solid and gaseous samples.

Revisiting the anomalous rf field penetration into a warm plasma
, 2005 Radio frequency waves do not penetrate into a plasma and are damped within it. The electric field of the wave and plasma current are concentrated near the plasma boundary in a skin layer.
