Burnishing hard materials can be used as an alternative finishing process.
While burnishing hard materials, the plasticity of the material under deformation is very limited.
Also, such deformation does not produce the effect of the piled-up material that occurs during burnishing soft materials.

The metallized pellet can then be used as a good raw material for steelmaking in electric arc furnace.
Given that biochar is a relatively new material, a huge amount of publications [1, 2] studying the possibilities of its application in various fields of science and technology can be observed.
In connection with the foregoing, the theoretical calculations of electrodynamic parameters of biochar-bearing materials are of particular interest and modeling the propagation of electromagnetic radiation of a wide frequency range in such composite structures is topical.

The films show a good response and repeatability as a humidity sensing materials.
If hydrogen defects were formed intentionally and bonded weakly, then a-CNx can be good materials as a humidity sensor [5].
These a-CNx films are potentially good humidity sensing materials.
