Summary: A spray atomization-assisted inductively coupled plasma system was used to synthesize ZnO nanoparticles at atmospheric pressure from a liquid precursor. The effect of process parameters on the morphology, particle size, and size distribution of the final particles was evaluated using FTIR, XRD, TEM, and SAED methods. The particles exhibited equiaxed morphology with mean particle sizes ranging from 17.5 ± 9.5 nm to 25.7 ± 11.2 nm.

Summary: Zinc oxide (ZnO) nanostructures with nanoparticle morphology were synthesized using [OMIM]Br ionic liquid as a solvent and template by ionothermal method. The effect of temperature on the properties of ZnO nanostructures was investigated, and it was found that higher annealing temperature in the ionic liquid resulted in ZnO nanoparticles with increased crystalline structure and enlarged band gap. The Z-scan technique was used to study the nonlinear optical (NLO) responses of the samples, and it was observed that ZnO samples prepared at higher temperatures and longer exposure time in [OMIM]Br ionic liquid exhibited greater NLO responses compared to Cu-doped ZnO.

Summary: Flexbile composites based on zinc oxide (ZnO) for piezoelectric sensors are synthesized using a simple and efficient plasma-liquid interaction strategy, resulting in enhanced piezoelectric response. The lamellar nanostructure of ZnO on carbon fiber (CF) surface can be regulated by adjusting plasma discharge time. With a piezoelectric coefficient d33 of 5.24 p.m./V based on the inverse piezoelectric effect, this study simplifies the fabrication process for ZnO/CF composites and offers a new approach for coupling piezoelectric materials on flexible substrates to improve piezoelectric response.

Summary: This review provides an overview of recent work on low-temperature plasma-assisted synthesis of zinc oxide nanoparticles, discussing gas-phase and surface reactions as well as various synthesis techniques. The thermodynamical nonequilibrium conditions enable the formation of chemically reactive species that readily interact with Zn precursors, leading to the formation of nanoparticles or nanowires. Different plasma parameters and techniques can be used to synthesize high-quality nanowires and nanoparticles, with potential for large-scale production.

Summary: This article reviews and summarizes recent work in this laboratory on the synthesis of advanced transparent conducting oxide nanopowders using plasma. The process involves selecting suitable precursors, injecting them into a non-transferred thermal plasma, vaporizing them, and forming nanosized oxide particles through vapor-phase reactions. The thermal plasma process shows great potential as an efficient technique for synthesizing oxide nanopowders.

Summary: The synthesis of uncapped palladium nanoparticles (PdNPs) through laser reduction in liquid using different precursors resulted in ultrasmall spherical NPs with high catalytic activity for Suzuki cross-coupling reactions and the reduction of para-nitrophenol. The stabilization of Pd precursors by lowering pH enabled the synthesis of PdNPs in sub-5 nm range, with additional large particles observed in electron microscopy images resulting from the aggregation of ultrasmall PdNPs. The ligand-free structure and small particle sizes generated through laser reduction in liquid contributed to the excellent catalytic activity of the PdNPs.

Summary: In this study, greenly synthesized heterogeneous zinc oxide nanoparticles (ZnO NPs) were treated by microwave to investigate their physicochemical properties and antibacterial activity. The results showed that the shape and size of ZnO NPs varied depending on the time of microwave heating and the UV-vis absorption peaks of the solution also changed. The heterogeneous ZnO NPs exhibited high antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA) and multidrug-resistant Pseudomonas aeruginosa (P. aeruginosa). This study presents a cost-effective method for synthesizing greenly heterogeneous ZnO NPs with excellent antibacterial activity against hospital-acquired infections.

Summary: The photocatalytic activity of ZnO films was enhanced by electrochemical reduction for 20 minutes, resulting in a removal efficiency of 96.5% for methylene blue (MB) after 180 minutes of light irradiation. This simple and effective method led to a fivefold increase in photocatalytic activity compared to untreated ZnO films, with relatively stable performance in consecutive cycle experiments.

Summary: A synthetic morphology-control method is reported to prepare 2D and 1D free-standing zinc oxide materials with ordered and nanoporous structures by converting liquid-crystalline zinc hydroxide carbonate (ZHC) nanoplates. The resultant zinc oxide films and microfibers exhibit nanoporous structures and preferred crystallographic orientations, preserving the alignment of ZHC nanoplates before conversion.
