Laser-based Diagnostics for Use in Ex-situ Lithium Co-deposit Analysis

Laser-induced breakdown spectroscopy (LIBS) and time of flight (TOF) mass spectrometry of laser-produced ions were tested for ex-situ analysis of lithium co-deposited layers produced by plasma deposition. It was found that LIBS provides an adequate way to observe and measure lithium content in thin co-deposited layers of about 1 µm thickness. TOF mass spectrometry data of the same layers was compared with LIBS. TOF mass spectrometry provided a better resolution; however, the simplicity of LIBS setup and the rate of measurement (less than one minute per measurement) makes it more attractive. Argon was observed in the co-deposited layers, indicating that it, and likely other inert gases, can remain trapped in lithium layers even after a prolonged exposure to and chemical reaction with atmospheric air

“Contemp. Children”: the problem of development of children's modern dance in the ural region

The article considers a problem that has become noticeable: in the Ural region, against the backdrop of the development of modern dance, folk stage dance is becoming less and less popular.В статье рассматривается ставшая заметной проблема: в Уральском регионе на фоне развития современного танца становится все менее популярным народный сценический танец
