“…Nanoparticles of platinum and gold were prepared with spatially confined atmospheric pressure plasma jets (APPJs) of hydrogen and helium respectively 21 , 24 . Similarly, APPJs were applied for direct nanoparticle coating of silver and palladium on silicon wafers, fabrics, and Al 2 O 3 (sapphire) for antibacterial and catalysis applications 22 . Owing to unique plasma-material interaction, future ultrathin materials such as doped graphene, reduced graphene (rGO), and beyond graphene 2D –materials (h-BN, MoS 2 ) could be made for super energy harvesting devices like supercapacitors and broad-band photodetectors 2 , 14 .…”

Dielectric-barrier-discharge (DBD) plasma jets provide viable state-of-the-art nonthermal processes for a wide range of nanomaterials including particle transport and deposition. We report the interaction of argon and helium plasma jets with the particle aerosol, produced by ns laser ablation of a silver target and subsequently their transport for deposition on a distant substrate. The nanofeatures and functionality of the nanoparticles, entrained and deposited with the two plasma jets were compared using high-resolution electron microscopy, helium ion microscopy, scanning electron microscopy, ultraviolet–visible spectroscopy, and in terms of the SERS effect. The plasma jet facilitates the transport of the particle aerosol under the upshot of plasma ionic wind, caused by the high electric field in the plasma. Compared to the helium plasma jet, the argon plasma jet leads to a relatively large particle deposition and promotes the formation of aggregates. The helium plasma jet enabled the deposition of spatially well dispersed particles. In both cases, the deposited particle was crystalline and plasmonic active. The plasma-driven altered morphology, expedient particle transport, and formation of agglomerates or spatially well dispersed particles are explained in plasma-induced ionic-wind, and dusty plasma framework. The findings are novel and interesting from the perspective of plasma–surface deposition, surface nanoengineering, and nanomaterial processing for applications in sensing, catalysis, surgical tools, futuristic coating technology, and heat-sensible biological activities.

“…A wide variety of nanomaterials have been produced with DBD plasma jets using source precursors 2,[13][14][15][16][17][18][19][20][21][22][23][24] . In the plasma interaction, the source precursors effectively dissociate to produce reactive radicals and ions and heat up the nanomaterial by reacting on the particle surface exothermally.…”

“…The atmospheric pressure plasma jets (APPJs) are generated in an open environment rather than in an air tight vessel [1]. In APPJs, a low-temperature, non-equilibrium plasma with abundant reactive nitrogen species (RNS) and reactive oxygen species (ROS) can be transferred away from the discharge region, which is suitable for the application in surface modification [2][3][4], biomedical engineering [5][6][7][8], nanomaterial preparation [9,10] and many other fields. During last two decades, APPJs became a hot topic of low-temperature plasma, and attracted more and more attentions.…”

In this paper, the air plasma jet produced by micro-hollow cathode discharge (MHCD) is investigated. The discharge is powered by a positive nanosecond pulse high voltage supply. The waveforms of the discharge, the images of the jet, the evolution of the plasma bullet and the reactive species are obtained to analyze the characteristics of the MHCD plasma jet. It is found that the length of the plasma jet is almost proportional to the air flow rate of 2–6 slm. Two plasma bullets appear one after another during a single period of the voltage waveform, and both of the two plasma bullets are formed during the positive pulse voltage off. The propagation velocity of the two plasma bullets is on the order of several hundred m/s, which is approximate to that of the air flow. These results indicate that the gas flow has an important influence on the formation of this MHCD plasma jet.
