The influence of surfactant type on the formation of zinc oxide nanoparticles via liquid phase pulsed laser ablation technique
...Show More Authors

To produce Zinc Oxide NanoParticles, ZnO-NPs, different methods can be used. However, the utilization of Liquid-Phase Pulsed Laser Ablation, LP-PLA, methodology of three distinct environment of aqueous using pure zinc plate will be one of the approaches for this job. Thus, in this work, concentrates on the influence of the results after employing some changes on the environment in other words, the influence of the NPs size and/or the NPs availability/appearance. Cetyltrimethylammonium Bromide, CTAB, is one of the three surfactants that have been used in the water-based solution. That is, the Sodium Dodecyl Sulfate, SDS, besides the Distilled Water, DW, the three surfactants will be ready when the molarity of the DW is around 10− 3 M. The specifications of the employed laser are: 800 nm as a wavelength, radiating with pulses of 130 fs as a duration, which will be repeated every 1ms (1 kHz). That is, with these laser settings, the femtosecond Ti: Sapphire laser was generated to irradiate the zinc target, which attain ablation inside the aforementioned solution. Hence, according to the sort of the surfactant that has been employed in the experiment, different shades were introduced in the resultant solutions, this reveals that the NPs are appeared with various dimensions. The shadow that has been captured is the white color which ranges from foggy to milky. Note that in the experiment was utilized the UV-VIS spectroscopy test in order to evaluate and characterize the ZnO-NPs that were produced. The creation of discrete sizes of ZnO-NP was verified by the surface plasmon resonance (SPR) spectra, which displayed separate absorbance peaks. For instance, the CTAB surfactant was at 207 nm, for the SDS, it was at 212 nm, while for the DW environment, it was at 218 nm. Accordingly, it was found, using the Scanning Electron Microscopy, SEM, captured images of the created nanoparticles, that the CTAB surfactant introduces the most regular/small sizes with respect to that produced using the SDS, which gives uneven sizes and shapes. Furthermore, the NPs generated in DW formed agglomerations with diameters in the micro range and exhibited a combination of spherical and hexagonal forms. The production of ZnO-NPs was confirmed using Fourier Transform Infrared Spectroscopy (FTIR) analysis, which demonstrated absorption readings in the 435–445 cm− 1 range.

Jurisdiction In Outer Space From The Perspective Of International Law
...Show More Authors

This research aims to clarify the principles governing the exploration and utilization of outer space, emphasizing the role of international law, particularly international criminal law, in addressing crimes committed beyond Earth whether aboard spacecraft, the International Space Station, or in outer space generally. It examines relevant international treaties governing outer space activities, evaluates their strengths and ambiguities, and highlights deficiencies in their provisions. Furthermore, the study analyzes traditional principles of state criminal jurisdiction territoriality, nationality, universality, and protection and assesses their applicability to offenses committed in outer space.

Optimizing the Surface Properties of Zirconium Implants with Germanium Coating
...Show More Authors

Background: zirconium (Zr) implants are known for having an aesthetically pleasing tooth-like colour Unlike the grey cervical collar that develops over time when titanium (Ti) implants are used in thin gingival biotypes. However, the surface qualities of Zr implants can be further improved. This present study examined using thermal vapour deposition (TVD) to coat Zr implants with germanium (Ge) to improve its physical and chemical characteristics and enhance soft and hard tissue responses. Materials and methods: Zr discs were divided into two groups; the uncoated (control) group was only grit-blasted with alumina particles while the coated (experimental) group was grit-blasted then coated with Ge via TVD. Field emission scanning ele

The Poetics of Transition in T. S. Eliot's "Ash-Wednesday"
...Show More Authors
  1. S. Eliot is one of the important founders of the modernist movement in literature, a cutting-edge poet of the first order. After his 1927 conversion to Anglicanism, he began calling himself a conservative, royal, and a classicist.
  2. "Ash Wednesday" is the first long poem written by him after his conversion. It deals with the struggle that ensues when one who has lacked faith acquires it. It is richly but ambiguously allusive, and deals with the aspiration to move from spiritual barrenness to hope for human salvation.

    "Ash Wednesday" not only struggles with an approach to faith but with an approach to a language capable of expressing it. Eliot's style is different from that that predates his conve

The Role of Banking Compliance to Reduce Risks to Run
...Show More Authors

The importance of operational risks increases with the increase in technological development, the development of banking operations, the extent of banking compliance, and the attempt of many banks to achieve quality in banking services. And the extent of the position occupied by Iraqi banks for banking compliance and reducing operational risks. The Basel Committee (2) paid its attention to operational risks and the interest of international banks to follow policies that work to ensure banking compliance and cover operational risks, because of its role in reducing losses due to increased costs and achieving an increase in profits. Realizing and working to confront the best possible and traditional methods, that some risks Operational problem

Arabian Political Regimes: Problems of Policies and Rule; An Introduction to Interpreting (The Arabian Spring) The Arab Region witnessed, since 2011, critical changes overthrew a group of Arab regimes in some of its countries, and the reaction of these changes are still going on up to now. These changes were given lots of justifications and interpretations. The current study tries to concentrate on the most important problems which were due to what was known as (The Arab Spring). The study proposes that the crisis which the countries of the area are exposed to is not spontaneous in many of its aspects. It is totally a crisis of rule and policies. Because it is a reflection of the nature of authority in the Arabian regimes on the one hand
