Selective etching of graphene edges by hydrogen plasma.
We devised a controlled hydrogen plasma reaction at 300 °C to etch graphene and graphene nanoribbons (GNRs) selectively at the edges over the basal plane. Atomic force microscope imaging showed that the etching rates for single-layer and few-layer (≥2 layers) graphene are 0.27 ± 0.05 nm/min and 0.10 ± 0.03 nm/min, respectively. Meanwhile, Raman spectroscopic mapping revealed no D band in the pl...
متن کاملHelium atmospheric pressure plasma jets touching dielectric and metal surfaces
Atmospheric pressure plasma jets (APPJs) are being investigated in the context plasma medicine and biotechnology applications, and surface functionalization. The composition of the surface being treated ranges from plastics, liquids, and biological tissue, to metals. The dielectric constant of these materials ranges from as low as 1.5 for plastics to near 80 for liquids, and essentially infinit...

ion by atomic O from the polymer chain has been discussed by different research groups as the most important channel for both low pressure plasma and atmospheric pressure plasma RH þ O ! R• þ OH p 1⁄4 10 ; 10 ; 10 ; (5) where p is the estimated reaction probability for the tertiary, secondary, and primary carbon sites provided by Bhoj and Kushner. It can be seen that the tertiary H has the high...
متن کاملMolecular Effects of Atmospheric Pressure Plasma Jet on the Double-Stranded DNA
Introduction The aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (APPJ) and interactions of this technology with double-stranded DNA using the polymerase chain reaction (PCR) and single-strand conformation polymorphism (SSCP) techniques. Materials and Methods The plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...
متن کاملChaos in atmospheric-pressure plasma jets
We report detailed characterization of a low-temperature atmosphericpressure plasma jet that exhibits regimes of periodic, quasi-periodic and chaotic behaviors. Power spectra, phase portraits, stroboscopic section and bifurcation diagram of the discharge current combine to comprehensively demonstrate the existence of chaos, and this evidence is strengthened with a nonlinear dynamics analysis us...
