Abstract This study aimed to predict the mechanical properties of SiC-reinforced epoxy. The cross-linked reinforced epoxy was simulated using Material Studio 7.0 (Accelrys, Inc.). Various percentages of SiC (0, 4, 6, 8, and 10) wt% were used in the simulations. A density curve and cell size diagram are obtained from MD simulations of SiC-epoxy nanocomposites. Under a 0.5 GPa pressure, Forcite dynamic simulations showed that amorphous cells have densities that are close to epoxy density (1.2 g cm−3). Simulations have shown that epoxy/SiC composites respond well to a variety of mechanical strains. Increasing the SiC weight percentage increases the stiffness matrix coefficient of epoxy composites, which is demonstrated by increased stiffness matrix coefficients. Computational studies of epoxy/SiC composites have suggested up to 10% SiC nanoparticles by weight will maintain the epoxy matrix’s density in industrial applications.

CdZnS thin films created via chemical bath deposition were examined to see how Cu doping affected their characteristics. Cu ions were added to the films in order to change their optical, structural, and morphological characteristics. These findings suggest that Cu doping can be used to modify the optical characteristics of CdZnS thin films. By using Xray diffraction (XRD) and the energy dispersive analysis of X-ray method (EDAX), we were able to investigate the compositional ratio as well as the structural features of the films. The field emission scanning electron microscopy (FESEM) technique was utilized in order to investigate the surface morphology of the produced films. The morphology of prepared films was fiber-like and in nanoscale. In addition, the UV–vis spectroscopy technique was utilized in order to characterize the optical properties of thin films. The prepared Cu-CdZnS film was found to have direct band gap equal to 2.64 eV and indirect gap equal to 2.4 eV.

In this investigation, the nanocomposites were synthesized using the physical mixing technique. This technique involved adding 20% titanium dioxide (TiO2) to a combination of PMMA and PVA in terms of weight percentages. The physical properties of prepared nanocomposite have been examined by using scanning electron microscope, X-ray diffraction technique XRD, Fourier transformed infrared spectrometry (FTIR) and UV–Vis spectroscopy. XRD patterns specified that the prepared composite was mostly crystalline in nature. Scanning electron micrograph showed that TiO2 nanoparticles were covered with a polymer blend matrix. FTIR results confirmed the presence of PVA and PMMA groups on the surface of TiO2 NPs. The MTT assay method was utilized on the MSF-7 cell line in order to evaluate the potential anticancer properties of the produced components. The nanocomposites showed good activity on cancer cells.

<abstract> <p>A functionally graded material (FGM) was prepared using epoxy resin reinforced with silicon dioxide with a particle size of 100 μm and weight percentages of 0, 20, 40, 60, and 80 wt%. In a gravity-molding process using the hand layup technique, specimens with international standard (ASTM)-calculated dimensions were created in a mold of poly(methyl methacrylate), which is also known as acrylic. Tensile, flexural, impact, infrared wave, and thermal conductivity tests, and X-ray diffraction (XRD) were conducted on specimens of the five layers of the FGM. The XRD and infrared spectroscopy demonstrated that the compositions of the silica particles and epoxy had a strong association with their physical structures. The findings of experimental tests indicated that increasing the ratio of silicon dioxide enhanced the mechanical properties, and the increase in modulus of elasticity was directly related to the weight percentage of the reinforcement material. The composite with 80% silica had a 526.88% higher modulus of elasticity than the pure epoxy specimen. Both tensile and flexural strengths of the composite material were maximal when 40 wt% of the particle silicon dioxide was utilized, which were 68.5% and 67.8% higher than those of the neat epoxy, respectively. The test results also revealed that the impact resistance of the FGM increased when the silica proportion increased, with a maximum value of 60 wt% silica particle content, which was an increase of 76.98% compared to pure epoxy. In addition, the thermal properties of epoxy resin improved when SiO<sub>2</sub> was added to the mixture. Thus, the addition of silica filler to composite materials directly proportionally increased their thermal conductivity to the weight ratio of the reinforcement material, which was 32.68–383.66%. FGM composed of up to 80% silica particles had the highest thermal conductivity.</p> </abstract>

This study examined the properties of polyvinyl alcohol (PVA) as a matrix composite, specifically focusing on the characterization techniques of UV-Visible spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDX). The investigation centered around a novel hybrid structure composed of CdZnS nanoparticles implanted within a composite matrix of PVA and Fe2O3. The analysis of microstructure data provided evidence of the influence of CdZnS nanoparticles on the structural characteristics of PVA–Fe2O3. The composites that were synthesized exhibited significant absorption peaks at wavelengths of 233 nm and 234 nm for PVA-Fe2O3 and PVA-Fe2O3-CdZnS, respectively. A progressive shift towards higher wavelength regions of absorption was found in these composites. The X-ray diffraction (XRD) analysis revealed an average crystalline grain size of 38.417 nm for Fe2O3 and 27.267 nm for PVA-Fe2O3-CdZnS.

Abstract Background Coronavirus 2019 (COVID-19) pandemic led to a massive global socio-economic tragedy that has impacted the ecosystem. This paper aims to contextualize urban and rural environmental situations during the COVID-19 pandemic in the Middle East and North Africa (MENA) Region. Results An online survey was conducted, 6770 participants were included in the final analysis, and 64% were females. The majority of the participants were urban citizens (74%). Over 50% of the urban residents significantly (p < 0.001) reported a reduction in noise, gathering in tourist areas, and gathering in malls and restaurants. Concerning the pollutants, most urban and rural areas have reported an increase in masks thrown in streets (69.49% vs. 73.22%, resp.; p = 0.003). Plastic bags and hospital waste also increased significantly with the same p-value of < 0.001 in urban areas compared with rural ones. The multifactorial logistic model for urban resident predictors achieved acceptable discrimination (AUROC = 0.633) according to age, crowdedness, noise and few pollutants. Conclusion The COVID-19 pandemic had a beneficial impact on the environment and at the same time, various challenges regarding plastic and medical wastes are rising which requires environmental interventions.

Abstract Background Coronavirus disease (COVID-19) pandemic has affected health and lifestyle behaviors of people globally. This project aims to identify the impact of COVID-19 on lifestyle behavior of individuals in the Middle East and North Africa (MENA) region during confinement. Methods We conducted an online survey in 17 countries (Egypt, Jordan, United Arab Emirates, Kuwait, Bahrain, Saudi Arabia, Oman, Qatar, Yemen, Syria, Palestine, Algeria, Morocco, Libya, Tunisia, Iraq, and Sudan) from the MENA region on August and September 2020. The questionnaire included self-reported information on lifestyle behaviors, including physical activity, eating habits, smoking, watching television, social media use and sleep before and during the pandemic. Logistic regression was performed to analyze the impact of COVID-19 on lifestyle behaviors. Results A total of 5896 participants were included in the final analysis and 62.8% were females. The BMI of the participants was 25.4 ± 5.8 kg/m2. Around 38.4% of the participants stopped practicing any physical activities during the confinement (P < 0.001), and 57.1% reported spending more than 2 h on social media (P < 0.001). There were no significant changes in smoking habits. Also, 30.9% reported an improvement in their eating habits compared with 24.8% reported worsening of their eating habits. Fast-food consumption decreased significantly in 48.8% of the study population. This direct/indirect exposure to COVID-19 was associated with an increased consumption of carbohydrates (OR = 1.09; 95% CI = 1.02–1.17; P = 0.01), egg (OR = 1.08; 95% CI = 1.02–1.16; P = 0.01), sugar (OR = 1.09; 95% CI = 1.02–1.16; P = 0.02), meat, and poultry (OR = 1.13; 95% CI = 1.06–1.20; P < 0.01). There was also associated increase in hours spent on watching television (OR = 1.07; 95% CI = 1.02–1.12; P < 0.01) and social media (OR = 1.09; 95% CI = 1.01–1.18; P = 0.03). However, our results showed a reduction in sleeping hours among those exposed to COVID-19 infection (OR = 0.85; 95% CI = 0.77–0.94; P < 0.01). Conclusions The COVID-19 pandemic was associated with an increase in food consumption and sedentary life. Being exposed to COVID-19 by direct infection or through an infected household is a significant predictor of amplifying these changes. Public health interventions are needed to address healthy lifestyle behaviors during and after the COVID-19 pandemic.
