Summary: Pressure retarded osmosis (PRO) technology utilizes semipermeable membranes to generate electrical energy through a turbine, but has not been fully exploited at commercial scale due to certain drawbacks. This study evaluates the impact of membrane permeability coefficients on energy generation of full-scale single-stage PRO systems. The findings reveal that a decrease in water permeability coefficient results in a significant reduction in energy production, while an increase in solute permeability coefficient has minimal effect at optimal operating points.

Summary: This study focuses on the development of new thin-film composite hollow fiber membranes for harvesting salinity gradient energy in pressure retarded osmosis applications. The membranes are designed to exploit the energy difference between wastewater reverse osmosis retentate and seawater reverse osmosis brine through osmotic mixing. Different-sized hollow fiber membranes were created using interfacial polymerization, and their performance was evaluated at lab scale and pilot scale. As module size increased, the water permeability and power density decreased, resulting in lower energy harvest in the pilot scale evaluation.

Summary: This study evaluates the techno-economic feasibility of the pressure retarded osmosis (PRO) technology for electricity generation using the salinity gradient between two water bodies. The use of improved membranes reduces the Levelized Cost of Electricity (LCOE) to USD 0.0704/kWh, compared to USD 0.1255/kWh with commercial membranes. However, with current membrane properties and mechanical equipment, a single-stage PRO process is not cost-competitive with other renewable energy sources.

Summary: The production of suitable catalytic materials has expanded considerably in recent years, particularly with the emergence of single atom catalysts (SACs), which offer a greater number of active sites and high catalytic activity. However, the reduced size of particles can lead to increased surface activity of metals, resulting in aggregation and sintering. Therefore, it is necessary to develop appropriate strategies for the synthesis and stability of SACs. Additionally, the mass production of SACs remains challenging, making the development of bimetallic SACs crucial. This review provides a comprehensive overview of the development of SACs in various fields, highlighting different synthesis protocols and large-scale manufacturing strategies.

Summary: Despite the use of renewable energy sources, fossil fuels remain as one of the primary energy sources. The combustion of low-quality fossil fuel materials leads to environmental damages such as acid rain and breathing issues. Conventional desulfurization methods lack efficiency due to increasing sulfur level restrictions, leading to the development of new methods like oxidative desulfurization to achieve fuel with minimum sulfur compounds. Wastewater treatment plays a crucial role in the industrial-scale application of this process.

Summary: This study proposed a tin sulfide (TS) coating onto polytetrafluoroethylene (PTFE) to enhance the anti-fouling properties of the membrane distillation (M.D.) membrane. The TS-PTFE membrane exhibited better anti-fouling properties, with fouling factors (FFs) of 10.4-13.1% compared to 14.4-16.5% of the pristine PTFE membrane. The fouling was attributed to pore blockage and cake formation of carbonous and nitrogenous compounds. Physical cleaning with deionized (DI) water effectively restored the water flux for the TS-PTFE membrane, with more than 97% recovery. The TS-PTFE membrane also showed better water flux and product quality at 55 ? and excellent stability in maintaining the contact angle over time.

Summary: This study introduces a novel approach using a supervised machine learning model to accurately predict reverse solute flux (RSF) in the forward osmosis process. The study employed feature engineering techniques to identify significant process parameters that influence RSF. Notably, the results demonstrate the high effectiveness of the Categorical boosting (CatBoost) machine learning algorithm in RSF prediction, achieving an R-square value of 0.94 and a root mean square error of 0.44 when comparing the actual and predicted data. Furthermore, the model underwent simulation using real experimental data, revealing a minimal percentage error ranging from 0 to 2% compared to the experimental reverse solute flux. The implications are particularly valuable in various applications involving reverse salt flux.
