Recently, the development of atmospheric pressure non-thermal plasma has been the research interest of many research groups world wide. This is because it is now realized that there is a need to develope cost effective plasma technology so that it can be more widely used in industry. The atmospheric pressure plasma devices being considered include the glow discharge and the dielectric...

Metal nanoparticles (NPs) due to their size and shape, have unique attributes that differ from their macrosized counterparts. These attributes contributed to an ever-growing list of applications, from medicine to electronics. The challenge is not only to create the nanoscale sizes but also to keep the metal NPs dispersed without agglomeration. Conventional methods to synthesize the NPs include...

A dielectric barrier discharge (DBD) type ozone generator was designed with oxygen /air as a feed gas. The discharge was generated by using high voltage power supply operating at line frequency (50Hz). The effect of gas flow rate and applied voltage on the concentration of the ozone was investigated. The flow rate was varied from 1 lit/min to 5 lit/ min for electrode area A=143.56 cm${}^2$ and...

Solitonic, periodic and chaotic behaviors of ion acoustic waves in an unmagnetized plasma
with q-nonextensive electrons and positrons are investigated applying the bifurcation theory
of planar dynamical systems. Model equations are transformed to a planar dynamical system
using a traveling wave transformation. Then by using the bifurcations of phase portraits of
this planar dynamical...

Effects of atmospheric plasma treatment on RD31 rice seed germination are studied. The seeds are treated with 5 mW of plasma for 10 sec. It is found that plasma treatments have positive effects on seed germination and seeding growth at the early stage. The germination rate is found to improve by 25% compared to non-treated seeds. In addition, the better quality of sprouts is obtained. It is...

PET scan is a medical imaging device for effective cancer diagnosis. It use medical radioisotopes such as 18-F. Since 18-F has short half-life, on site production is inevitable. Normally, cyclotron is used in the big hospital to produce 18-F. Plasma focus, a much cheaper and compact system, is an alternative device for 18-F production. The plasma focus can generate energetic particles which...
