Disproportionation of nitrogen induced by DC plasma-driven electrolysis in a nitrogen atmosphere

Evaluation of Nitrogen Diffusion in Plasma Nitrided Iron by Various

   Diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (OM), microhardness depth profiling (HDP), scanning electron microscopy (SEM), x-ray diffraction (XRD), glow discharge optical emission spectroscopy (GDOES), and secondary ion mass spectroscopy (SIMS). Plasma ni...

Osteoblast differentiation and disinfection induced by nitrogen plasma-treated surfaces.

Plasma technology is widely employed to tailor the surface chemistry of polymeric biomaterials. In this work, nitrogen-containing functional groups were generated on a polymer surface by N₂ plasma immersion ion implantation (PIII). We evaluated the abilities of the resulting surface to inhibit bacterial growth and to enhance osteoblast differentiation from the perspective of bone tissue enginee...

Oxidized and Reduced Nitrogen in the Atmosphere

Nitrogen Dioxide Concentrations in the Atmosphere

This Policy Position Statement outlines the technical challenges involved in the assessment and management of future concentrations of nitrogen dioxide (NO2) in the atmosphere. It notes that NO2 is the pollutant responsible for most breaches in European standards for air quality in the UK and that, as a result, a robust evidence based approach is required to assess future concentrations of this...

Particle in Cell-Monte Carlo Collisions of a Plasma Column Driven by Surface Wave Plasma Discharges

In this work, applicability of Particle in Cell-Monte Carlo Collisions (PIC-MCC) simulation method for better understanding of the plasma physical mechanisms and real important aspects of a plasma column driven by surface wave plasma discharges that is used in plasma antennas is examined. Via the implementation of geometry and physical parameters of the plasma column to an Object Oriented PIC-M...
