“…Moreover, ZnO nanostructures can be classified into different types of dimensions from 0D to 3D leading to different applications such as photocatalytic activity, solar cells, anti-bacterial activities, supercapacitors, and chemical and biological sensors [19][20][21]. The ZnO has been synthesized in various methods including hydrothermal synthesis [22], electrochemical deposition [23], chemical vapor deposition [24,25], spray pyrolysis [26], radio-frequency magnetron sputtering [27], molecular beam epitaxy [28], pulsed laser deposition [29], arc discharge method [30], and sparking method [31].…”

Glyphosate (N-(phosphonomethyl)glycine) is well known nonselective and broad-spectrum herbicide that has been extensively used in agricultural areas around the world to increase agricultural productivity. However, the utilization of glyphosate can cause environmental contamination and health problems. Therefore, the detection of glyphosate with a fast, low-cost, and portable sensor is still important. In this work, the electrochemical sensor has been developed by modifying of working surface on the screen-printed silver electrode (SPAgE) with a mixtures solution between zinc oxide nanoparticles (ZnO-NPs) and poly (diallyldimethylammonium chloride) (PDDA) by the drop-casting process. The ZnO-NPs have been prepared based on a sparking method by using pure zinc wires. The ZnO-NPs/PDDA/SPAgE sensor shows a wide range of glyphosate detection (0 µM - 5 mM). The limit of detection of ZnO-NPs/PDDA/SPAgE is 2.84 µM. The ZnO-NPs/PDDA/SPAgE sensor exhibits high selective towards glyphosate with minimal interference from other commonly used herbicides including paraquat, butachlor-propanil and glufosinate-ammonium. Furthermore, the ZnO-NPs/PDDA/SPAgE sensor demonstrates a good estimation of glyphosate concentration in real samples such as green tea, corn juice and mango juice.

Nickel oxide (NiO) film receives attention from the field of optoelectronics due to its wide band gap and high transparency. By using a sparking method, the deposition of the NiO film is facile and unique. However, the NiO film made by the sparking method indicates a porous surface with an agglomeration of its particles. In order to reduce the porousness of the NiO film, the assistance of a permanent magnet in the sparking apparatus is presented. Here, we report the investigation of the NiO film and the p-NiO/n-ZnO heterojunction deposited by the sparking method under a magnetic field. Our results demonstrate that the porosity of the NiO film was reduced by increasing the magnitude of a magnetic field from 0 mT to 375 mT. Furthermore, the crystallinity and the electrical properties of the NiO film are improved by the influent of a magnetic field. For heterojunction, the best device shows the rectification ratio of 95 and the ideality factor of 4.92. This work provides an alternative method for the deposition of the NiO film with promising applications in optoelectronic devices.

“…Such a synthesis is carried out by combining nanostructured materials and various physicochemical processes for their production . One of the most promising and popular areas of the synthesis of composite materials is the multicomponent compounds formation which, depending on their composition, can exhibit different properties . The traditionally used metal oxides (SnO 2 , ZnO, WO 3 , In 2 O 3 , MoO 3 ) as functional layers in chemical sensors, photovoltaics, photocatalysis, spintronics, and photonics are replaced by functional nanostructured films of the combined composition (ZnO–SnO 2 , SnO 2 –WO 3 , SnO 2 –MoO 3 , MoO 3 –Fe 2 O 3 , etc.).…”

Low‐profile anodic alumina matrices of 1 μm thick with pore sizes of 105 and 160 nm are formed by two‐step anodizing of Al layers and are used as templates for the deposition of multicomponent metal oxide films on their surfaces. The metal oxide systems of Sr2FeMoO6−δ, FexMoyOz, and SnxMoyOz composites with carbon nanotubes are synthesized by electrophoretic deposition, sol–gel method, and drop method using aqueous salt solutions and are annealed at 373–473 K for 1–2 h and at 773–1123 K for 2–10 h. The morphology, microstructure, and composition of the porous alumina matrices with multicomponent metal oxides films are examined by scanning electron microscopy, energy‐dispersive X‐ray microanalysis, and X‐ray phase analysis. The use of anodic alumina matrices allows reducing the grain dimensions and gives uniformity to the microstructure and properties of the metal oxide films. The carbon nanotubes increase the working surface of the functional layer and its electrical conductivity. The variation in the synthesis conditions of deposited films and anodic alumina matrices configuration allows forming of different complex composition compounds with reproducible structure and properties.
