Considers of nanostructures created beneath different modes of submersion testimony of silver on permeable silicon (PS) for their utility as dynamic substrates in monster Raman spectroscopy (SRS) are displayed. PS was shaped by anodizing monocrystalline silicon in an aqueous-alcoholic arrangement of hydrofluoric corrosive. The reflection spectra of the gotten silver nanostructures on PC have been examined. It is uncovered that to form ideal conditions for SERS spectroscopy utilizing silver nanostructures on PC, it is vital to utilize an energizing laser with a wavelength of 400–450 nm.

Internet of nano things (IoNT) is a new and modern part of the internet of things (IoT). Applications thatoperate in the field of nano scale show a new advantage in communication networks. IoNT opened the door to many applications in various fields with new features derived from the advantages of nanotechnology. In this work, a description of the IoNT during 2015-2021 was achieved, including taxonomy, architecture, motives, applications and challenges, in addition to recommendations. The architecture of the IoNT and the most important technologies used in Nano communication networks have been identified, with an indication of the advantages of each. This study, we hope, will make a contribution to this field of science, thus contributing to providing assistance to researchers in this emerging field and coveringthe challenges they face in this way.That would permit communication between nano-devices to be conventional, making these calibrations to be implemented in various IoNT applications. Until the IoNT system is designed without any problems in the near future, which if achieved, will provide great services, especially in medical applications and other applications.

Liquid Ion Exchange joined with Cloud point extraction methodology was used for the separation of Magnesium (II) from aqueous and determinewhereas 10 mL aqueous solution that contains50 μg Mg2+ ion iscomplex with 1×10-3M 8-Hydroxy quinoline (8-HQ) at a suitable basic medium it well give higher extraction efficiency at optimum conditions, needs heating the aqueous solution in suitable temperature degree for enough time to formacloud point layer (CPL).Therefore, the optimum conditions that yielded the good CPL havea small aggregation volumewhich isappropriate for continuing the ion pair association Complex between Magnesium ion and 8-Hydroxy quinoline.

Though photonics displays an attractive solution to the speed limit of electronics, decreasing the size of photonic devicesis one of the major problems withimplementingphotonic integrated circuitsthat are regarded as the challenges to produce all-optical computers. Plasmonic can solve these problems, it isa potential solution to fill the gaps in the electronics (large bandwidth and ultra-high-speed) and photonics (diffraction limit due to miniaturization size). In this paper, Nano-rings Insulator-Metal-Insulator (IMI) plasmonic waveguides havebeen used to propose, design, simulate, and perform all-optical universal logic gates (NOR and NAND gates). By using the Finite Element Method (FEM), the structure of the proposed plasmonic universal logic gates are designed and numerically simulated by two dimensions (2-D) structure. Silver and Glass materials were chosen to construct the proposed structure. The function of the proposed plasmonic NOR and NAND logic gates was achieved by the destructive and constructive interferencesprinciple. The performance of the proposed device is measured by three criteria; transmission, extension ratio, and modulation depth. Numerical simulations show that a transmission threshold (0.3) thatallows achieving the proposed plasmonic universal logic gates in one structure at 1550 nm operating wavelength. The properties of this device wereas follows: The transmission exceeds 100% in one state of NAND gate, mediumvaluesof Extension Ratio, very high MD values, and very small footprint. In the future, this device will be the accessto the nanophotonic integrated circuits and it has regarded fundamental building block for all-optical computers.

Nanoparticles are one of the most important technologies of today and the future. This groundbreaking technology is considered a very significant domain among all the fields of science due to its tangible capacity in improving products, treating diseases, serving mankind in all spheres of life, and realizing future scientific revolutions in the fields of physics, chemistry, biology, engineering, and other sciences. Therefore, it is truly necessary to take advantage of the distinct properties of nanomaterials. Hence, synthesized nanoparticles have been shown to be enjoying anti-proliferating antioxidant, anti-migration, antioagulant and anti-cancer antipathogenic characteristics in the laboratory. Accordingly, this study came to prominence in this field. The biochemical equipment used in nanoparticle bacterial biosynthesis was subsequently proven. Many of these biochemical types of equipment have been used as part of a cellular detoxification resistance mechanism that involves altering inorganic ions solubility by reducing and/or precipitating soluble toxic to insoluble non-toxic nanostructures. Microorganisms, such as bacteria, are used as an environmentally responsible strategy, and an alternative in the method of chemical agents when nanoparticles are synthesized. Extracellular as well as intracellular biocatalytic (including possible excretion) synthesis involves mainly oxidreductase enzymeslike NADH dependent reductase nitrate NADPH, NADPH sulphite reductase alfa (NADPH dependent on sulfite reductase) and cells.
