Abstract Cerium‐doped zinc oxide (Ce‐ZnO) nanocones with cerium concentrations of 0, 0.5, 1, and 2 % were synthesized using a sol‐gel method. Their effectiveness as photocatalysts for degrading dyes such Rhodamine B (RhB), Methylene Orange (MO), Violet (MV) was evaluated. The optical structural properties, particle size distribution, morphology these examined X‐ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet‐visible (UV‐Vis) spectrophotometry. XRD results confirmed that the highly crystalline hexagonal wurtzite structure, noticeable blue shift observed in Ce‐doped ZnO compared to pure ZnO. photocatalytic performance under UV exposure showed doping significantly improved degradation RhB, MO, MV. Notably, doped 1 exhibited highest efficiency, achieving 100 RhB within 60 minutes. Additionally, Ce‐ZnO demonstrated efficiencies 86.3 MO 74.9 MV same time frame.

Rhamnolipids (RLs) are widely studied biosurfactants with significant industrial potential in cosmetics, pharmaceuticals, and bioremediation due to their excellent surface activity, emulsifying properties bioactive characteristics. However, high production costs impede mass production. This study investigates the immobilization of Pseudomonas stutzeri lipase (PSL) on various supports enhance RL synthesis efficiency, focusing yield regioselectivity enzymatic 4-O-lauroylrhamnose by transesterification rhamnose vinyl laurate. Three methods were compared: covalent binding, adsorption Celite, hydrophobic supports. The efficiency varied depending method used, lowest observed for Celite (56 %), followed Sepabeads (EC-EP/S 78 % EC-EP/L 70 highest (83-97 %, EC-OD being best at 97 %). For 4-O-lauroylrhamnose, Sepabeads™ EC-EP yielded low conversions restricted conformational freedom enzyme. Celite® 545 resulted moderate conversion rates, limited electrostatic interactions restricting enzyme activity. most promising results obtained supports, particularly Purolite® ECR8806F, achieving nearly complete maintaining 4-position both THF green solvent 2-methyltetrahydrofuran (2-MeTHF). highlights critical role support hydrophobicity active area immobilized performance. PSL ECR8806F demonstrated sustainable RLs production, showing reusability, stability productivity across multiple reaction cycles. presents a advancement optimizing conditions, facilitating way more cost-effective applications.

Abstract Diversification of the applications fats and oils has led to increasing demands on their properties. Interesterification reactions are used alter composition constituent triacylglycerols (commonly known as triglycerides) introduce desired properties enhance value. Enzymatic interesterification catalysts have garnered attention owing safety, efficiency, natural origin. However, enzymes sensitive temperature, moisture, pH conditions, posing risks inactivation. Additionally, enzymatic slower reaction rates than chemical catalysts. To suppress hydrolysis side reaction, lipases with high activity in microaqueous systems should be selected. Industrial that use non‐immobilized, powdered overcome these issues insolubility oils. Continuous systems, which passed through a lipase‐packed column, offer processing capacity per unit enzyme weight, because interact concentrations lipase. These advances commercialization medium‐ long‐chain cocoa butter substitutes. Our technology using offers solution challenges handling non‐immobilized ones. This innovative approach allows for efficient isolation recovery after maximizing performance. catalysis can reduce energy consumption CO 2 emissions eliminate need by avoiding water washing wastewater treatment. distinctive features make promising industrial preparation higher‐value worldwide.
