Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

One of the wide spread and economic methods of carbon nanomaterials (CNM) synthesis is an arc evaporation of graphite [1]. Products, formed in plasma due to the evaporation of graphite anode and containing CNM, are deposited on cathode and on reactor cold walls. Taken specimens are examined for different characteristics with little attention to physical-chemical processes, taking place at both on electrodes and in plasma. This work represents the authors’ opinion and offers a model (scheme) of CNM formation as a deposit on cathode, based on charged particles behavior in electromagnetic field patterns at the experimental temperature and pressure gradients along the arc axis.
