Potential breakthroughs in energy supply and assessment of the breakthrough likelihood within the next decade. These breakthroughs will create opportunities and challenges for the Arabian Gulf countries, where hydrocarbon resources are focal for government revenues, economic activity and exports.

This study focuses on the pathogenesis and potential treatment of posterior capsule opacification (PCO) and summarizes the mechanisms through which drugs, microRNAs, and currently investigated clinical therapies prevent epithelial-mesenchymal transition (EMT). The findings indicate that the small mother against decapentaplegic (SMAD) pathway plays a crucial role in effectively addressing EMT. Through these research directions, it is believed that effective treatments for PCO can be developed in the near future.

Waste animal fat is converted into alternative fuels for compression ignition engines, and the results regarding engine performance, combustion, and emission characteristics are discussed. The present research helps waste management and the usability of novel fuels as fuel substitutes. Also, this work supports attaining the Sustainable Development Goals (SDGs) of 7, 9, 12, and 13.

This study explores the time-quantile-frequency adjustment path of green growth to energy vulnerability, uncertainties, and geopolitical risks, focusing on the US economy. The analysis uncovers that these factors dampen green growth more profoundly in the immediate and medium terms. However, in the long term, green growth prospers amidst energy vulnerability. Further insights highlight the pollution-reducing effects of energy efficiency and digitalization.

This present research focus on the synthesis of PANI-CuFe₂O₄ (PCF) nanocomposite for the photocatalytic degradation of toxic methylene blue (MB) dye. Nanocomposite showed significant elimination of MB dye with maximum removal of 96% with the best fitting of Langmuir isotherm, an indication of monolayer formation on catalyst surface through the interaction between nanocomposite and dye molecule.

The article presents an advanced IoT-based hand hygiene compliance monitoring system designed to enhance healthcare-associated infection (HAI) prevention. Utilizing Bluetooth Low Energy (BLE) for precise location tracking and ultrasonic sensors for handwashing duration detection, the system achieves high accuracy in controlled environments. Integrated with a cloud server and real-time data visualization via Streamlit, it offers an automated solution for monitoring hand hygiene compliance, overcoming the limitations of traditional observation methods. Further research is required to optimize its effectiveness in clinical settings and reduce HAIs.

This study uses GIS-based Random Forest (RF) and Support Vector Machine (SVM) machine learning models to evaluate groundwater potential zones (GWPZs) in the Gidabo watershed utilizing data from 75 boreholes and springs. Water bodies, springs, low-lying areas, and forests all have good GWPZs, while shrubland and grassland have poor GWPZs.

This study investigates curcumin's protective effects on heatstroke-induced acute liver injury by targeting pyroptosis and enhancing sirtuin 1 (SIRT1) expression. The research demonstrates curcumin's potential to mitigate liver damage and systemic inflammation, suggesting SIRT1 as a promising therapeutic target for heatstroke-related hepatic injury.
