A Mach-Zehnder electro-optic modulator (EOM) was fabricated employing pulsed laser deposition (PLD) method. Lithium Niobate (LN) was bonded to silicon nanocrystal substrate such that a waveguide combined structures were obtained. The over-all Properties of prepared device were investigated. The formation of LN was ensured by the x-ray diffraction results were the formation of ∆ phase was confirmed by the diffraction of x-rays from the (012) and (302) diffraction plans. The AFM results reflect the formation of highly uniform nanostructured with maximum roughness of about 12.9 nm. The constructed device shows that the recent improvements in hybrid MZ modulators using pulse laser deposition PLD and different electro-optic material have shown low loss and wide modulation bandwidth.

“…Furthermore, the crystallite size was calculated in accordance with the Debye-Scherrer's module. 28 The crystallite size of 7, 10, and 15 mm CuO NPs at 2θ = 35.5, was estimated to be 20, 38, and 21 nm, respectively. It is well-known that the crystal quality can be evaluated using the crystallite size, where the full width at half maximum (FWHM) is inversely proportional to the crystal size in accordance with Debye-Scherrer's module.…”

In this article, a simple new technique for the green synthesis of copper oxide nanoparticles (CuO NPs) using peroxidases oxidoreductases (POX) enzyme extracted from fig leaves for antifungal and antibacterial activities has been reported. Subsequently, a comprehensive investigation of the structural, optical, and morphological properties of the synthesized CuO NPs was elucidated, using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Electrodiagnostic (EDX), atomic force microscopy (AFM), and transmission electron microscopy (TEM) analysis techniques. Specifically, the resultant nanoparticles are spherical with a diameter ranging from 28–68. CuO NPs were further tested for their antifungal activity against Candida and Aspergillus species, while the antibacterial activity was screened in contradiction of pathogenic bacterial strains namely gram-positive Staphylococcus aureus and gram-negative Asinobacterial species. The present study reveals a convenient use of POX fig leaves extract as fuel, for the well-organized synthesis of CuO NPs via green synthesis technique to acquire considerably active antifungal and antibacterial materials.

“…Several nanoparticles, ZnO in particular, delivers an outstanding antimicrobial performance in a wide range of bacteria such as Escherichia coli and Staphylococcus aureus (9,11). Furthermore, ZnO has demonstrated some attractive applications such as solar cells, catalysts, photodetectors, and biomedical/antibacterial activity (12,13,14,15).Herein, the interaction between the bacteria and ZnO nanoparticles are highly effective if the ZnO is prepared using a biological method due to the absence of undesired/toxic chemical compounds. Also, ZnO nanoparticles are biocompatible and nontoxic (16,17,18).…”

This study was aimed to demonstrate the biosynthesis procedure of Zinc oxide nanoparticles (ZnO NPs) using Prodigiosin pigment which in turn produced from particular environmental bacteria isolates Serratiamarcescensas a stabilizing and reducing agent. Additionally, the synthesis conditions were precisely taken into consideration as a pH of 7 and a temperature of 50°C alongside a concentration of prodigiosin of 12 mg/ml with 5mg precursor of zinc acetate in deionized distilled water (DDW) 50ml. Biosynthesized ZnO nanoparticles have presented many applications such as catalysis, biosensing, anticancer, and biomedical, etc. The optimum condition for ZnO biosynthesis was characterized through several techniques such as UV-Vis, AFM, XRD, FT-IR, and FE-SEM. In particular, a cut-off phenomenon of the biological synthesized ZnO was found at around 280 nmusing UV-Vis, while spherical shape particles were noticed using FE-SEM techniques. Also, the AFM analysis revealed that ZnO NPs an average diameter size of 45.02 nm.And the effect of ZnO NPs on bacteriaPseudomonas aeruginosaon an inhibition zone 29mm.
