Comparison of field emission of carbon, carbon nitride and boron carbon nitride nanotubes
Acta Physica Sinica, 2005 Carbon,CNx and BCN nanotubes were synthesized by pyrolysis at 860℃ and purified. Thin films of the purified samples were fabricated by a screen-printing method. The field emission effect of these films was compared. It was found that the turn-on field was 2.22，1.1 and 4.4V/μm,and the current density at 5.7V/μm was 1400，3000 and ＜50μA/cm2 for C, CNx and

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
