Microwave-synthesized composite preformed particle gels based on tragacanth gum and palygorskite for high-salinity high-temperature conditions by Ahmed Ben Ali (17792594)

“…Swelling behavior in real Gulf seawater (TDS = 45,2 mg/L) and rheological measurements taken at elevated temperatures (80 °C and 100 °C) showed that the addition of Pal enhanced gel rigidity but slightly reduced swelling capacity, likely due to increased steric hindrance. The formulation TPAC₂ (2.5 g Pal) exhibited an optimal balance between swelling (14.2 g/g at 100 °C) and mechanical strength, making it a strong candidate for reservoir applications. …”

Enhancing photocatalytic partial oxidation of methane to methanol: Experimental investigation of 2D/metal oxide composite catalysts by Amira Chebbi (19756983)

“…Among the three catalysts tested, the composite W₁₈O₄₉/g-C₃N₄ demonstrated remarkable catalytic activity of 62.3 μmol g−1 h−1 under visible light, nearly 4-fold higher than pristine W₁₈O₄₉ and 5-fold higher than g-C₃N₄. The enhanced performance is attributed to the forming of a Z-scheme heterojunction system, as evidenced by XPS analysis showing increased oxygen vacancy density and strong electronic coupling between the components, further confirmed by electrochemical characterization revealing improved charge separation efficiency. …”
