“…Metal oxide particles and nanoparticles such as manganese oxide, nickel oxide, zirconium oxide, titanium oxide, tungsten oxide, iridium oxide, and iron oxide have been successfully used for immobilization and direct electrochemistry of biomolecules [38]. In the past, research on the synthesis of nanosized porous nickel oxide materials and its applications in catalytic reactions, industrial processes and electrochromic devices has been rather intense [39][40][41]. Furthermore, due to the excellent electrocatalytic activity and good antifouling properties of electrodes modified with nickel oxide, these modified electrodes have been used for electrocatalytic oxidation and determination of insulin, thiols, disulfides, mercaptans, and sulfur oxoanions [42][43][44].…”

Glassy carbon electrode modified with electrodeposited nickel oxide nanoparticles (NiOxNPs) was used as electrocatalyst for oxidation of omeprazole and pentoperazole in alkaline solution. The modified electrode exhibited efficient electrocatalytic activity for the oxidation of omeprazole and pentoperazole with relatively high sensitivity, excellent stability, and long lifetime. Hydrodynamic amperometric method is used for determination of selected analytes. Under optimized condition, the linear concentration range, detection limit, and sensitivity of modified electrode toward omeprazole detection are 4.5-120 μM, 0.4 μM (at signal to noise 3), and 40.1 nA μM −1 cm −2 , respectively. For pantoperazole, hydrodynamic amperometric determination yielded calibration curve with linear range of 2.5-180 μM, detection limit of 0.2 μM, and sensitivity of 39.2 nA μM −1 cm −2 , respectively. The proposed method was successfully applied to pentoperazole and omeprazole determination in drug samples.

“…Since numerous utilizations of NiO, for example, concoction sensors (Stamataki et al 2008), impetuses (Bakar et al 2009), hostile to ferromagnetic material (Mallick and Mishra 2012), dye sensitized solar cells (DSSCs) (Bandara and Weerasinghe 2005), electrochromic gadgets (Kamal et al 2005), it draws in the specialists consideration towards it. A few strategies to get ready NiO thin films relied on upon the applications, synthetic and physical, for example, chemical bath deposition (Vidales-Hurtado and Mendoza-Galván 2008), sol-gel (Zayim et al 2008), sputtering (Mendoza-Galván et al 2009) and beat laser testimony (Valyukh et al 2010).…”

NiO thin films doped with three different concentrations of Ag nanoparticles (AgNPs) are deposited on glass slide substrates at 450°C by sputtering method. The effect of AgNPs on the optical and structural characteristics of NiO thin film is studied by X-ray diffraction, scanning electron microscopy and ultraviolet-visible spectra. It is found that all the samples have a cubic structure. When Ag doping is made, the intensity of the diffraction peaks and the transmittance are decreased. On the other hand, the optical band gaps of NiO films doped with AgNPs are increased.

“…[1], are widely used for technological applications; all these films are n-type semiconductors. NiO is one of these oxides and last years, a growing interest has been devoted to nickel oxide thin films [2][3][4][5][6][7][8][9][10]. It is an interesting material for use as an antiferromagnetic layer [11], p-type transparent conducting film [12], in electrochromic devices [13] and functional sensor layer for chemical sensors [14].…”

The interest in NiO films has been growing fast due to their importance in many applications in science and technology. NiO films are an attractive material and are used common application area such as an antiferromagnetic layer, p-type transparent conducting film, electrochromic devices and chemical sensors. Also, NiO is a good candidate for p-type semiconductor films due to its wide band gap energy from 3.6 to 4.0 eV. In this work, NiO films have been grown on glass substrates by ultrasonic spray pyrolysis technique using NiCl 2 .6H 2 O as spraying solution. Films have been annealed at 500 °C in air during 1 h. Optical measurements of NiO film have been carried out at room temperature using a UV-VIS spectrophotometer. Band gap of as-deposited and annealed films have been calculated by using optical method and found as 3.67 eV and 3.7 eV, respectively. Thicknesses of the films have been determined by filmetrics thin film measurement system. Surface properties of the films have been investigated with an atomic force microscope and electrical resistivity measurements have been performed by a four probe set-up. Consequently, the optical, electrical and surface differences have been determined between as-deposited and annealed NiO films produced by ultrasonic spray pyrolysis.
