Summary: Despite Africa's reserves of renewable energy, policymakers in oil-producing countries tend to rely on traditional energy sources, leading to increased CO2 emissions and global warming. Our study found that renewable energy has no significant effect on economic growth in these countries, while CO2 emissions have a positive impact on the economic growth of Algeria, Equatorial Guinea, and Egypt. We recommend that policymakers pay more attention to the utilization of renewable energy.

Summary: India has ambitious targets for wind and solar energy installation by 2030, with solar making up the majority of capacity. The study found that systems with solar photovoltaic comprising 25% to 50% of the total renewable target have the lowest carbon mitigation costs. Contrary to assumptions, meeting high renewable targets in India will reduce the need for new fossil fuel power plants. High renewable energy systems with a majority of wind plants could result in electricity costs similar to fossil fuel-dominated systems.

Summary: The Belt and Road Initiative (BRI) has had positive economic impacts but negative ecological consequences. This research examines the effects of institutional quality and renewable/non-renewable energy consumption on CO2 emissions for 75 BRI countries from 1990 to 2019. The findings show that improving institutional quality and increasing renewable energy negatively affect CO2 emissions, while non-renewable energy has a positive impact. It is crucial for BRI to establish effective plans to reduce non-renewable energy use, enhance institutional quality, resolve disputes, and promote harmony in affected nations.

Summary: In this study, a hybrid structure, MIL-53(Al)@MWCNT, was synthesized by combining MIL-53(Al) particles and -COOH functionalized multi-walled carbon nanotube (MWCNT). The hybrid structure was then embedded in a polyethersulfone (PES) polymer matrix to prepare a mixed matrix membrane (MMM) for CO2/CH4 and CO2/N2 separation. The addition of MWCNTs prevented MIL-53(Al) aggregation, improved membrane mechanical properties, and enhanced gas separation efficiency.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance. The reaction parameters and catalyst stability were also investigated.
