“…These plasmas are interesting because of their ability to produce strongly oxidizing species (OH and O radicals, H 2 O 2 ) and UV radiation. The water based plasmas have also demonstrated their potential for cleaning, chemical grafting, and physical surface modifications of polymer materials …”

Recently, plasma deposition at atmospheric pressure has become a promising technology due to its reduced equipment costs and its possibility of in‐line processing. The main aim of this work was to show a process for the deposition of functional layers on hollow objects surface by plasma discharge generated above the liquid electrolyte. In principle, this process is based on the surface dielectric barrier discharge, where the plasma is generated from the boundary line of liquid precursor and dielectric surface. As a model precursor compound a hexamethyldisiloxane was chosen for deposition on external and internal wall surface of polytetrafluoroethylene tube.

“…As evident in Figure 7a, the high-resolution XPS spectrum of Zn2p3/2 is fitted by two peaks located at a binding energy of 1021.21 and 1022.18 eV, and can be attributed to the ZnO and Zn(OH)2, respectively [23,27,29]. It can be clearly seen in Figure 7b that the highresolution XPS spectrum of O1s is fitted by four peaks located at 530.75, 531.72 532.78, and 533.79 eV, corresponding to the Zn-O bonding of the ZnO structure, Zn(OH)2, C-O or C=O, and C-O-C, respectively [23,26,29]. The high-resolution XPS spectrum of C1s is shown in Figure 7c.…”

“…In the case of a ZnO coating via the SPPS deposition method, several works [17][18][19][20][21][22][23] have reported the use of different Zn-based compounds as precursors, among which the most widely used compounds are zinc nitrate (Zn(NO 3 ) 2 •6H 2 O), zinc chloride (ZnCl 2 ), zinc acetate (Zn(OAc) 2 •2H 2 O), and zinc acetylacetonate (Zn(C 5 H 7 O 2 ) 2 •xH 2 O). However, on the basis of current knowledge, no complete investigation has been reported for ZnO thin films deposited on wood surfaces by atmospheric pressure plasma jet (APPJ) via the SPPS method.…”

In the present work, the solution precursor plasma spray (SPPS) process was used to deposit zinc oxide (ZnO) coatings on wood surfaces using zinc nitrate solution as precursor to improve the hydrophobicity and the color stability of European beech wood under exposure to ultraviolet (UV) light. The surface morphology and topography of the wood samples and the coatings were characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The formation of ZnO was detected with the help of X-ray photoelectron spectroscopy (XPS) and by Fourier transform infrared (FTIR) spectroscopy. The FTIR spectra of the coated samples showed the typical Zn–O band at 445 cm−1. According to the XPS analysis, the coatings consist of two different Zn-containing species: ZnO and Zn(OH)2. Variation of the deposition parameters showed that the most significant parameters affecting the microstructure of the coating were the solution concentration, the deposition scan speed, and carrier gas flow rate. The wettability behaviors of the coated wood were evaluated by measuring the water contact angle (WCA). The coatings that completely covered the wood substrates showed hydrophobic behaviors. UV-protection of wood surfaces after an artificial UV light irradiation was evaluated by color measurements and FTIR spectroscopy. The ZnO-coated wood surfaces were more resistant to color change during UV radiation exposure. The total color change decreased up to 60%. Additionally, the FTIR spectra showed that the wood surfaces coated with ZnO had more stability. The carbonyl groups formation and C=C-bonds consumption were significantly lower.

“…The low temperature permits treating polymers, and the design of some plasma equipment allow it to penetrate challenging cavities, which was verified in a stack of polymer discs with openings that shaped a winding cavity [7]. Plasma technology has also been used for the deposit of films containing zinc, using a solution of zinc nitrate hexahydrate salt in water as a source of zinc [8]. The industrial application of plasma processes for medical devices has been extensively demonstrated [9,10].…”

The main component of plasma medicine is the use of low-temperature plasma (LTP) as a powerful tool for biomedical applications. LTP generates high reactivity at low temperatures and can be activated with noble gases with molecular mixtures or compressed air. LTP reactive species are quickly produced, and are a remarkably good source of reactive oxygen and nitrogen species including singlet oxygen (O 2), ozone (O 3), hydroxyl radicals (OH), nitrous oxide (NO), and nitrogen dioxide (NO 2). Its low gas temperature and highly reactive nonequilibrium chemistry make it appropriate for the alteration of inorganic surfaces and delicate biological systems. Treatment of oral biofilm-related infections, treatment of wounds and skin diseases, assistance in cancer treatment, treatment of viruses' infections (e.g. herpes simplex), and optimization of implants surfaces are included among the extensive plasma medicine applications. Each of these applications will be discussed in this review article.
