Preparation and Physical Properties of Mg-Zn Nano-crystal by Laser-induced Plasma
...Show More Authors

To learn how the manner of preparation influences film development, this study examined film expansion under a variety of deposition settings. To learn about the membrane’s properties and to ascertain the optimal pretreatment conditions, which are represented by ambient temperature and pressure, Laser pressure of 2.5[Formula: see text]m bar, the laser energy density of 500[Formula: see text]mJ, distortion ratio ([Formula: see text]) as a function of laser pulse count, all achieved with the double-frequency Nd: YAG laser operating in quality-factor mode at 1064[Formula: see text]nm. MgxZn[Formula: see text] films of thickness [Formula: see text][Formula: see text]nm were deposited on glass substrates at pulse frequencies of (1–6)[Formula: see text]Hz and pulse durations of 10[Formula: see text]ns. The spectrum of rays. The X-rays demonstrated that the diffraction peaks’ findings show that the crystallinity of the films is highly dependent on the quantity of magnesium present in the layers. All the generated movies feature a polycrystalline hexagonal membrane structure, with the (101) plane being the main reflection. The average particle size was determined to be less than 50[Formula: see text]nm using FE-SEM measurements, and (RMS) of the surface roughness of the membranes MgxZn[Formula: see text] may be calculated using AFM analysis. The spectrum spans from (300)[Formula: see text]nm to (900) nm in wavelength. All films have a transmittance rate of more than 70% for the visible area of the spectrum[Formula: see text][Formula: see text][Formula: see text](400–800)[Formula: see text]nm, and in one model, it reaches greater than 95%. The energy gap (Eg) for these films is (2.68, 2.6, 2.4 and 2.32) electron volts, with a standard deviation of (100, 200, 300, and 400) shoot. In addition, the energy gap values drop as the laser pulse strength increases, and the range in which these values may be set is quite narrow (2.68–2.32).

Influence of Laser Irradiation Times on Properties of Porous Silicon
...Show More Authors

Porous silicon (P-Si) has been produced in this work by photoelectrochemical (PEC) etching process. The irradiation has been achieved using diode laser of (2 W) power and 810 nm wavelength. The influence of various irradiation times on the properties of P-Si material such as P-Si layer thickness, surface aspect, pore diameter and the thickness of walls between pores as well as porosity and etching rate was investigated by depending on the scanning electron micrograph (SEM) technique and gravimetric measurements.

Preparation and Evaluation of Some Properties of Heat Cured Acrylic Based Denture Soft Liner
...Show More Authors

Background: The base of the denture is largely responsible for providing the prosthesis with retention, stability, and support by being closely adapted to the oral mucosa. However; the process of bone resorption is irreversible and may lead to an inadequate fit of the prosthesis; this can be overcome by relining. Materials and methods: Acrylic based soft denture liner is prepared by preparing polymer from purified methylmethacrylate monomer with (10-2) initiator and (30%) dibutylphthalate plasticizer concentrations. Biological properties were evaluated in comparison with the control material through subcutaneous specimens' implantation in the New Zealand rabbits. Excisional biopsies were taken after (1, 3, days 1, 2, 3, 4 weeks) period. Mic

The Effect of Temperature and pH on the Removal / Recovery of ZN++ from Solution by Chemical Coagulation
...Show More Authors

This work was conducted to study the treatment of industrial waste water, and more particularly those in the General Company of Electrical Industries.This waste water, has zinc ion with maximum concentration in solution of 90 ppm.
The reuse of such effluent can be made possible via appropriate treatments, such as chemical coagulation, Na2S is used as coagulant.
The parameters that influenced the waste water treatment are: temperature, pH, dose of coagulant and settling time.
It was found that the best condition for zinc removal, within the range of operation used ,were a temperature of 20C a pH value of 13 , a coagulant dose of 15 g Na2S /400ml solution and a settling time of 7 days. Under these conditions the zinc concentrat
