Thermal stability and decomposition pathways of zeolitic imidazolate frameworks for future catalytic thermochemical applications
(Elsevier B.V., 2026-05-05) Samy Yousef; Justas Eimontas; Nerijus Striūgas; Vilmantė Kudelytė; Mohammed Ali Abdelnaby
Metal-organic frameworks (MOFs) have recently gained attention as catalysts in catalytic pyrolysis (CP); however, their application is constrained by thermal instability at high operating temperatures, which calls for work to find the most suitable class for this purpose. In this context, this work introduces zeolitic imidazolate frameworks (ZIFs) as thermally stable and commercially available MOF candidates for CP applications by investigating their decomposition behaviour, kinetics, and structure stability. Thermogravimetric analysis (TGA) was carried out under various heating rates, coupled with TG-FTIR and GC/MS to observe evolved vapors. The kinetic and thermodynamic characteristics were simulated using linear and nonlinear models, and a trained artificial neural network (ANN) was used to predict decomposition regions. The results showed that ZIF-67 and ZIF-8 exhibited high thermal stability up to 580 °C and 600 °C, respectively, followed by rapid degradation releasing 1H-imidazole, 2-methyl- compound. ZIF-8 exhibited higher activation energy (450–461 kJ/mol) compared to 340–352 kJ/mol (ZIF-67), with both materials following endothermic decomposition approach. The ANN model successfully captured the decomposition region (R2 ≥ 0.999). Finally, the structure analysis showed that porosity loss rises with faster heating rates, with ZIF-67 proving more stable than ZIF-8, especially at higher rates. SEM-EDX results also confirmed that cobalt nodes are more stable than zinc. These results demonstrate that ZIFs have high thermal and porosity stability at low heating rates, while at higher heating rates, ZIF-67 exhibits exceptional stability, making it a promising catalyst for the CP of feedstocks with decomposition temperatures below 580 °C (such as biomass and plastic waste).
An Assessment of the Impact of Retail and Corporate Credit Risk on the Performance of Egyptian Banks: The Moderating Effect of Bank Efficiency
(MSA UNIVERSITY, 2025) Ahella Ayman Roshdy Abdelghaffar Ahmed; Professor Dr. Mohamed Eldeeb; Dr. Sara Sobhy
Banks play an important role in promoting economic growth by acting as financial intermediaries reallocating financial resources to the most productive investments.However, banks confront different types of risks that must be closely monitored to avoid unexpected losses that could jeopardize the banks' viability. In this regard, the article observed that credit risk in terms of corporate and retail has recently increased dramatically in Egypt, and they are not synchronized over time, indicating that the determinants may be distinct. Furthermore, the analysis found no papers in the literature that split credit risk into retail and corporate before assessing bank performance in Egypt. As a result, the paper aimed to investigate the impact of retail and credit risk on bank performance using the GMM for the period 2011-2020 to provide improved insights to Egyptian banks that would aid in their projection of future bank performance. The findings demonstrated that classified credit risk has varying effects on bank performance, highlighting the need to categorize credit risk to construct more robust estimated models of bank performance.
Corporate Sustainable Performance and Profitability: Exploring the Moderating Role of Liquidity and Stock Volatility in Egypt
(MSA UNIVERSITY, 2024) Nada Salah Hussein Mahmoud El Gabr; Prof. Doaa Salman Abd; Dr. Asmaa Hamdy
Purpose: The purpose of this study is to investigate whether Corporate sustainable performance (CSP) impacts the firm profitability by exploring the moderating role of liquidity and stock volatility in Egypt. Design/methodology/approach: The study sample covers the 30 listed firms in S&P/EGX -ESG from 2010 to 2022. Data analyzed using the regression. Two regression models were estimated, the first model used the CSP as an independent variable measured by ESG scores disclosures, while CSP was measured in the second model using the intensity index. Firm profitability was measured by ROA as a dependent variable in the first model in the second model firm profitability was measured by ℓ𝓃 ROA. Research limitations/implications: This study is limited to the context of Egypt; however, it provides insights to policymakers, managers, and investors to adopt sustainability as an integral part of their decision-making process due to its positive impact on firms’ profitability. Findings : Results demonstrated that there is a positive significant impact between corporate sustainable performance and firm profitability. Furthermore, empirical data indicated that companies that display a high degree of commitment to sustainable practices and aggressively pursue admission into the sustainability index tend to earn the highest level of profitability. Originality/value : The study renders a vision of the role of CSP on firm performance. This study tries to determine whether there is a relationship between CSP and profitability in the context of Egypt, and if they are positive, negative, or even neutral by exploring the moderating role of liquidity and stock volatility.
The effect of gamification technique in teaching on student’s performance – An Experimental Study
(MSA UNIVERSITY, 2025) Alaa Osama Fekry; Professor Dr. El-Sayed A. Nagy
Gamification has emerged as an effective educational tool, integrating game mechanics into learning environments to enhance students’ academic performance and engagement. Despite its growing application, there remains a limited understanding of its differential impact across age groups and varying task complexities. This study investigates the effect of gamification on student performance through an experimental design involving Grade 2 and Grade 7 students; two distinct developmental stages selected to explore how cognitive influences responsiveness to gamified learning. Grade 2 students represent early childhood learners, while Grade 7 students are transitioning into adolescence, allowing for a comparative analysis of age-related differences. A randomized controlled design was conducted in which participants were divided into experimental and control groups. The experimental groups engaged in a gamified version, while the control groups received the same content through traditional instructional methods. The gamification design was aligned with the learning outcomes (LOs) of the science course to ensure educational relevance and consistency across both groups. Quantitative data were analyzed using appropriate parametric and non-parametric statistical tests to assess academic achievement, while qualitative insights were gathered through structured classroom observations. Results indicated a statistically significant improvement in academic performance among students exposed to gamified instruction, with Grade 2 students showing a more pronounced response. Observational data further revealed increased engagement, motivation, and classroom participation among experimental groups. This study provides novel insights into how gamification dynamics interact with age and task difficulty, emphasizing the need for age-appropriate design in educational gamification. The findings offer practical implications for educators and curriculum designers seeking to implement gamified learning environments effectively
Evaluating the Effect of Daylighting on Students’ Productivity at Egyptian Universities
(MSA UNIVERSITY, 2025-11-21) Kareem Mohamed Abdelhamed Hafez Alhefnawy; Prof. Dr. Hanan Mostafa Kamal Sabry; Assoc. Prof. Dr. Shady Shawky Saifelnasr
This research examines the relationship between lighting conditions and student productivity in Egyptian university design studios. While previous studies have relied heavily on subjective measures, this investigation employs a mixed-methods approach that integrates both objective task performance metrics and subjective user responses. The study addresses three primary questions: how daylighting influences productivity compared to artificial lighting, how to effectively measure productivity in educational settings, and whether students show preferences between lighting types. The experimental results reveal that lighting effects are highly context-dependent, moderated significantly by gender and workspace view. Female students demonstrated substantially higher productivity in daylit spaces with courtyard views, while artificial lighting supported better task performance in urban-view settings. The findings indicate that when illumination levels are quantitatively adequate and free from visual discomfort, daylighting and artificial lighting can yield comparable productivity outcomes. This suggests that effective lighting design may depend more on achieving proper light intensity and distribution than on the specific light source. Although most students strongly preferred daylight for its psychological and physiological benefits, this preference did not consistently correlate with higher objective productivity scores. Correlation analysis showed moderate to strong alignment betweenobjective and subjective measures within each lighting type, while daylight and artificial lighting environments demonstrated distinct effects on student performance and perception. The study concludes that effective lighting design requires moving beyond universal solutions to adopt evidence-based, user-centric strategies that account for individual differences and spatial contexts. These findings provide architects and educational planners with empirical evidence for creating learning environments that balance both productivity outcomes and student well-being.
