“…The structural characterization of the Ni 1-x Co x O thin films is carried out by X-ray diffraction method is shown in figure 7. It can be noticed that all the patterns exhibit diffraction peaks around (2h*38°and 44°) referred to (111) and (200) crystal plan, respectively, the peaks position was in accordance with Rahman et al [23]. The positions of obtain peaks with and without presence in the XRD spectra indicating that the Ni 1-x Co x O thin films are polycrystalline in nature with cubic structure, which is in agreement with other reports [24] of the cubic type of NiO (JCPDS) No.…”

The effect of Co doping on optical, structural and electrical properties of Ni 1-x Co x O thin films has been successfully deposited on glass substrate by Sol-Gel Sping coating technique. The main objective of this research is to study the Ni 1-x Co x O thin films to determine the optical gap energy by various methods and compare of calculated values. The transmission spectra show that the Ni 1-x Co x O thin films have a good optical transparency in the visible region. The optical gap energy was varied between 3.8 and 4.05 eV, which was determined by various methods and equations. These are found in the drawn of A, A 2 , a, a 2 (Ahm) 2 and (ahm) 2 as a function of the photon energy hm, the suitable method to calculate the optical energy was observed for (Ahm) 2 versus hm, but this method can not be related to the film thickness. The urbach energy of the Ni 1-x Co x O thin films also was determined by the curves of LnA and Lna as a function of photon energy hm. The deduce by LnA versus hm is also suitable to estimate the urbach energy. However, the Ni 0.96 Co 0.04 O thin films have a few defects with minimum value of urbach energy. XRD patterns of the Ni 1-x Co x O thin films indicate that some films are polycrystalline with cubic structure. The electrical conductivity of our films is in the order of 8.2*10-3 (X.cm) 1 .

“…Ni 2+ is internalized into the cell membrane and reacts with sulfhydryl groups. Therefore, the activity of synthetase in the microorganism becomes disrupted, thus the cellulose grows through cell division, which in turn leads to microbe death (Rahman et al, 2018).…”

“…Other metals like copper, zinc, gold, and silica share these antimicrobial characteristics with silver, but despite they effectiveness, they have not been approved for human or animal use yet. Other inorganic materials have been also evaluated but with less intensity, which can (Rahman et al, 2018) Hydroxyl 28 -P. mirabilis Antibacterial be related to the difficulty for their approval for human use and thus, their introduction as clinical treatments. Nevertheless, green synthesis is gaining more relevance due to the greater biological and environmental compatibility of these NPs.…”

“…Furthermore, some investigations have exposed that their synthetized NPs could have the potential to be used either as a catheter coating or as a systemic administration drug. However, they need to expand their in vitro and in vivo evidence for their approval for their clinical use as UTIs treatment (Sivaraj et al, 2014;Li et al, 2014;Qasim et al, 2015;Turcheniuk et al, 2015;Malarkodi and Rajeshkumar, 2017;Al Tameemi et al, 2017;Nsayef Muslim et al, 2017;Lopez-Carrizales et al, 2018;Mishra and Padhy, 2018;Rahman et al, 2018;Tiwari et al, 2018;El-Batal et al, 2019;Rajivgandhi et al, 2019). Other inorganic NPs have also shown a great potential like adjuvants in combination therapy with antibiotics (Bhande et al, 2013;Paralikar et al, 2019).…”

Urinary tract infection (UTI) is one of the most common reasons for antibiotic treatment. Nevertheless, uropathogens are steadily becoming resistant to currently available therapies. In this context, nanotechnology emerges as an innovative and promising approach among diverse strategies currently under development. In this review we deeply discuss different nanoparticles (NPs) used in UTI treatment, including organic NPs, nanodiamonds, chemical and green synthesized inorganic NPs, and NPs made of composite materials. In addition, we compare the effects of different NPs against uropathogens in vivo and in vitro and discuss their potential impact the in the near future.

Ni1-xFexO (x = 0.00, 0.01, 0.02, 0.03, 0.04) samples were successfully synthesized by co-precipitation method. Room temperature structural properties were analyzed by PXRD studies and Rietveld profile refinement technique. The structural results revealed that the samples assigned by cubic symmetry with Fm3m space group. Effects of structural properties with respect to the Iron substitutions in NiO matrix was investigated. Charge density profiles of the prepared materials were also investigated by maximum entropy method. From MEM analysis, it found that the ionic nature of Ni-O bond decreased. The surface morphologies were determined by scanning electron microscopic (SEM) measurements.
