“…Further investigation into sustainable and eco-friendly ink formulations may allow fabrication of electrolyte gating for transistor-based technology. Nanostructured ZnO is also a known as a chemoresistive and ultraviolet (UV) light-sensing material [99,100]. Recently, Manjunath et al suggested preparation of thixotropic pastes by mixing solution combustion synthesized ZnO powder as a functional material with a Na-carboxy-methyl cellulose binder in water, in order to fabricate a gas sensor for ammonia, ethanol, Cl 2 , H 2 S, and liquefied petroleum gas (LPG) [101].…”

Solution-based printing approaches permit digital designs to be converted into physical objects by depositing materials in a layer-by-layer additive fashion from microscale to nanoscale resolution. The extraordinary adaptability of this technology to different inks and substrates has received substantial interest in the recent literature. In such a context, this review specifically focuses on the realization of inks for the deposition of ZnO, a well-known wide bandgap semiconductor inorganic material showing an impressive number of applications in electronic, optoelectronic, and piezoelectric devices. Herein, we present an updated review of the latest advancements on the ink formulations and printing techniques for ZnO-based nanocrystalline inks, as well as of the major applications which have been demonstrated. The most relevant ink-processing conditions so far explored will be correlated with the resulting film morphologies, showing the possibility to tune the ZnO ink composition to achieve facile, versatile, and scalable fabrication of devices of different natures.

“…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.
