In this work, we precisely measure the electrical properties of a low-temperature atmospheric-pressure helium plasma jet, such as the rf current and voltage, and analyze in detail its characteristics. The results show that the instantaneous plasma cu

Dynamics of albumin agglomeration and dissolution induced by a helium plasma jet using the Schlieren visualization technique were demonstrated. The Schlieren technique enabled us to visualize the plasma-induced agglomeration of albumin on the albumin

Abstract Chemical modification of carbon nanotube surface can controllably modulate their optical properties. Here we report a simple and effective synthesis method of oxygen-doped single-walled carbon nanotubes (o-SWCNTs), in which a thin film of SW

We present a study quantitatively demonstrating that the method of synthesis (gas phase, fixed bed, non-fixed bed) represents a determining factor in the level of crystallinity in growing single wall carbon nanotubes (SWCNTs). Using far infrared spec

In this work, we report a novel, mini microplasma-assisted gas-phase synthesis reactor which enables the localized deposition of high quality carbon nanotubes (CNTs). Analogous to conventional gas-phase growth, which utilizes the furnace heating to i

We used atomic force microscopy to characterize the surface topography of p-GaN exposed to N2 and NH3 plasma under quasi-atmospheric pressure using a microwave-excited plasma source with a microstrip line structure. The exposure time was varied from
