Non‐thermal atmospheric pressure plasma jets/plumes are playing an increasingly important role in various plasma processing applications. This is because of their practical capability to provide plasmas that are not spatially bound or confined by electrodes. This capability is very desirable in many situations such as in biomedical applications. Various types of ‘cold’ plasma jets have, therefore, been developed to better suit specific uses. In this paper a review of the different cold plasma jets developed to date is presented. The jets are classified according to their power sources, which cover a wide frequency spectrum from DC to microwaves. Each jet is characterized by providing its operational parameters such as its electrodes system, plasma temperature, jet/plume geometrical size (length, radius), power consumption, and gas mixtures used. Applications of each jet are also briefly covered.

“…The authors report that the neutral gas temperature reaches up to 7 × 10 3 K. They also report an electron number density of 2 × 10 13 cm −3 . The HF plasma pencil/torch has been used in several applications that range from the production of fullerene, polymerization in liquids, the cleaning of archeological glass artifacts, etc 51…”

“…4,5 These plasma sources can be generated with sinusoidal excitation at 60 Hz, 6 kHz, 5,[7][8][9][10] MHz, 1,4,[11][12][13][14] and with repetitive nanosecond pulses at kilohertz. 8,15 For many of their applications, nonthermal plasma jets offer a useful practicality of separating the plasma generation region from the application region thus facilitating access to an extensive range of reaction chemistry.…”

A hypersonic plasma bullet train traveling in an atmospheric dielectric-barrier discharge jet

et al. 2008

An experimental observation of fast-moving plasma bullets produced in an atmospheric dielectric-barrier discharge jet is reported in this paper. Nanosecond imaging suggests that the atmospheric discharge jet consists of a plasma bullet train traveling at a hypersonic speed from 7.0km∕sto43.1km∕s. Yet on a millisecond scale, the bullet train appears as a plasma jet of several centimeters long. The plasma bullets are produced through several possible mechanisms, the most likely of which is related to the ionization wave. Time and space resolved optical emission spectroscopy show that reactive plasma species can be delivered to different spatial sites with varying quantities.

Plasma-chemical modifications of cellulose for biomedical applications

et al. 2014

A 6-carboxycellulose (in medicine known as "oxidized cellulose" or "oxycellulose") is one of the cellulose derivatives popular in the field of surgery. Health products based on oxidized cellulose are great local hemostatics with unique bactericidal and fully bioabsorbable effects. Traditional process of native cellulose oxidation is described as a complex radical reaction in strong acidic liquid medium doped by toxic nitrous radicals (NO*). Our plasma-chemical reaction demonstrates a new synthesis method of oxidized cellulose with unique bactericidal effect. This plasma-chemical treatment is based on atmospheric plasma discharge in liquid medium leading to the oxidation of polysaccharide molecules resulting in oxycellulose. Final oxycellulose properties were evaluated by infrared spectroscopy and carboxyl content determination. The biological impact showed a strong germicidal effect.
