Synergistic Effect of Ag <sub>2</sub> O@CuO Photocatalyst in Engineering Highly Hydrophilic Photocatalytic Membranes With Superior Self‐Cleaning Properties for Organic Dyes Elimination
...Show More Authors
ABSTRACT<p> Polyvinyl chloride (PVC) ultrafiltration membranes were efficiently fabricated using a (0.1–0.5 wt.%) Ag <sub>2</sub> O@CuO heterojunction photocatalyst to form a PVC/Ag <sub>2</sub> O@CuO photocatalytic membrane (PM) stimulated by UV light. The PVC/Ag <sub>2</sub> O@CuO PM fabricated using the phase inversion process resulted in significant improvement in internal morphology, porosity, pure water flux, and separation efficacy of the doped membranes. The efficacy of the PVC/Ag <sub>2</sub> O@CuO PMs was evaluated in the elimination of Rhodamine B (RhB) dye. The highest photodegradation of RhB (96.9%) was obtained using the PM2 membrane that contains 0.3 wt.% Ag <sub>2</sub> O@CuO photocatalyst at an influent pH of 6.5, a feed RhB concentration of 5 mg/L, a RhB solution volume of 2000 mL, an influent flow rate of 1 L/min under UV light irradiation for 90 min. PM2 membrane demonstrated antifouling features in terms of flux recovery ratio, reversible fouling, irreversible fouling, and total fouling, and 90% of RhB was removed after five cycles of use. The kinetic results indicated that the photocatalytic oxidation of RhB dye by the PM2 membrane followed the pseudo‐first‐order kinetic model, with an apparent rate constant of 0.0289 min <sup>−1</sup> . Studying the Langmuir–Hinshelwood model resulted in an intrinsic photocatalytic reaction rate constant of 0.7666 mg/L.min and an equilibrium adsorption constant of 0.045 L/mg. </p>

Effect of Sulfur on Characterization of AgInSe<sub>1.8</sub>S<sub>0.2</sub> Thin Film and n-AgInSe<sub>1.8</sub>S<sub>0.2</sub> / p-Si Solar Cell
...Show More Authors

Abstract Ternary Silver Indium selenide Sulfur AgInSe1.8S0.2 in pure form and with a 0.2 ratio of Sulfur were fabricated via thermal evaporation under vacuum 3*10-6 torr on glasses substrates with a thickness of (550) nm. These films were investigated to understand their structural, optical, and Hall Characteristics. X-ray diffraction analysis was employed to examine the impact of varying Sulfur ratios on the structural properties. The results revealed that the AgInSe1.8S0.2 thin films in their pure form and with a 0.2 Sulfur ratio, both at room temperature and after annealing at 500 K, exhibited a polycrystalline nature with a tetragonal structure and a predominant orientation along the (112) plane, indicating an enhanced de

Abstract<p>This research is devoted to the effect of investigation of the ZnO content on the structural and electrical properties of (NiO)<sub>1-x</sub> (ZnO)<sub>x</sub> films prepared by pulsed laser precipitation on the glass substrate at room temperature. Thin-film (NiO)<sub>1-x</sub> (ZnO)<sub>x</sub> sediments were deposited with different composition ratios where x = 0, 0.2, 0.4, 0.6 and 1.0 with a thickness of n150nm. The diffraction pattern for X-ray analysis reveals that the structure of the prepared thin films is identical with the cubic phase and hexadecimal stage of x = 0 and 0.1, respectively while the structure is mixed with the remaining x </p> ...

Abstract<p>The existing investigation explains the consequence of irradiation of violet laser on the optic properties of (CoO<sub>2</sub>) films. The film was equipped by the utilization of semi-computerized spray pyrolysis technique (SCSPT), it is the first time that this technique is used in the preparation and irradiation using a laser in this technique. From the XRD analysis, the crystalline existence with trigonal crystal system was when the received films were processed by continuous violet laser (405 nm) with power (1W) for different laser irradiation time using different number of times a laser scan (0, 6, 9, 12, 15 and 18 times) with total irradiation time(0,30,45,60,75,90 min</p> ...

Role of Tin Oxide on the Structural, Optical and Electrical Properties of Pulsed Laser Deposited (ZnO)&lt;sub&gt;1-x&lt;/sub&gt;(SnO&lt;sub&gt;2&lt;/sub&gt;)&lt;sub&gt;x &lt;/sub&gt;Composite Thin Films

This research examines the electrical, optical, and structural properties of zinc oxide (ZnO) and tin(IV) oxide (ZnO)1-x (SnO2)x composite thin films made by pulsed laser deposition, as well as the impact of composition concentration. The structural study of (ZnO)1-x (SnO2)x composites and thin films was conducted by X-ray analysis (XRD). Optical properties were investigated by UV–Vis infrared spectroscopy. The structural analysis revealed that all prepared thin-film composites were polycrystalline, exhibiting both hexagonal wurtzite and tetragonal phases for pure ZnO and SnO2, as well as a mixture of both phases for x=0.2 and 0.4. In contrast, the SnO2 phase was predominant for x=0.6 and 0.8. The increase in crystal size in the (

Topological Indices for the Resize Graph of (G&lt;sub&gt;2&lt;/sub&gt;(3))
...Show More Authors

Indexes of topological play a crucial role in mathematical chemistry and network theory, providing valuable insights into the structural properties of graphs. In this study, we investigate the Resize graph of G2(3), a significant algebraic structure arising from the exceptional Lie group (G2) over the finite field F3. We compute several well-known topological indices, including the Zagreb indices, Wiener index, and Randić index, to analyze the graph's connectivity and complexity. Our results reveal intricate relationships between the algebraic structure of G2(3) and its graphical properties, offering a deeper understanding of its combinatorial and spectral characteristics. These findings contribute to the broader study of algebraic graph t

Ultrafast lithium disilicate veneer debonding time assisted by a CO<sub>2</sub> laser with temperature control
...Show More Authors

We report on using a CO2 (10.6 µm) laser to debond the lithium disilicate veneers. Sixty-four sound human premolar teeth and 64 veneer specimens were used in the study. The zigzag movement via CO2 laser handpiece along with an air-cooled jet to prevent temperature elevation above the necrosis temperature limit (5.5 C°) was applied. The optimal deboning irradiation time was super-fast, at about 5 seconds at 3 Watt CO2 laser power. It is 20 times less than any previously published work for veneers debonding. The enamel beneath the debonded veneers has been assessed by atomic force microscopy (AFM) and shear stress technique as criteria for the easiness of debonding. The

Abstract<p>In this research, we studied the effect of concentration carriers on the efficiency of the N749-TiO<sub>2</sub> heterogeneous solar cell based on quantum electron transfer theory using a donor-acceptor scenario. The photoelectric properties of the N749-TiO<sub>2</sub> interfaces in dye sensitized solar cells DSSCs are calculated using the J-V curves. For the (CH3)3COH solvent, the N749-TiO<sub>2</sub> heterogeneous solar cell shows that the concentration carrier together with the strength coupling are the main factors affecting the current density, fill factor and efficiency. The current density and current increase as the concentration increases and the </p> ... Show More
