Summary: By 2040, over 500 million people will be added to Africa's cities, marking the largest urbanization in history. However, nonrenewable fossil energy sources are insufficient to meet Africa's energy needs, leading to intensified global warming. Africa has a huge potential for biomass energy, which can combat climate change and energy shortage. This study evaluates the Ouagadougou Biogas Plant, the first large-scale biogas generation plant in West Africa, and finds that it has significant economic, environmental, and social benefits.

Summary: Ensuring the sustainability of energy systems, especially in power generation, is a major concern in today's society. Exergy analysis is a widely accepted tool for evaluating the performance and sustainability of different power plants. The research results demonstrate that the sustainability index of a combined cycle power plant is higher than that of gas turbine power plants, due to the incorporation of a bottoming cycle.

Summary: This study investigates a solar energy power plant integrated with a biomass-based hydrogen production system. High-purity hydrogen is obtained from biomass-based syngas using thermochemical processes. The plant is simulated using Aspen HYSYS software, and the thermodynamic performance of the hybrid system is evaluated using exergy analysis. The results show that designing and operating a hybrid high-performance energy system using two different renewable sources is an encouraging approach to reduce the environmental impact of energy conversion processes and effectively utilize energy resources.

Summary: Anaerobic digestion of sludge produces a large amount of sewage sludge anaerobic digestate (SSAD) that can be reused. A novel green substrate prepared by mixing SSAD and its biochar (SSBC) showed positive effects on plant growth, with higher seedling survival rates and biomass compared to soil. The green substrate also had lower greenhouse gas emissions and NH3 volatilization, making it an effective and economical option for disposing excessive SSAD.

Summary: This study evaluates and optimizes the effects of microwave power and drying air temperatures in a combined microwave-convective drying process. The results show that higher drying air temperature leads to increased energy loss and decreased exergy efficiency. Increasing microwave power and decreasing drying air temperature can reduce GHG emissions and improve exergy efficiency. Therefore, heat recovery mechanisms are necessary to reduce energy waste and GHG emissions.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
