Enological pectinase immobilized on polymer microparticles as efficient biocata...
Denchev, Z.; Oliveira, Sandra Cristina Gomes; Araújo, Samuel; Dencheva, Nadya VasilevaOne of the key areas of polymer biotechnology is the use of high molecular weight compounds as supports for enzymes, enhancing their utility in industrial applications. Free pectinase is commonly employed as a biocatalyst in wine clarification; however, its removal, recovery, and reuse are not feasible. To address these limitations, this study focuses on the immobilization of a commercial pectinolytic preparati...
Polyamide microparticles as promising enzyme carriers and their application in ...
Braz, Joana Filipa Barros; Dencheva, Nadya Vasileva; Oliveira, Sandra Cristina Gomes; Araújo, Samuel; Denchev, Z.The widespread use of industrial-scale processes employing enzymatic catalysts is still hindered by the inactivation of free enzymes due to various denaturant agents and the difficulty, or even impossibility, of their recovery from the reaction medium after use. To address these limitations, a new strategy has been proposed, centered on polymer-assisted biocatalysts created through the non-covalent immobilizati...

El aprendizaje de las funciones logarítmicas por parte de estudiantes de 12.º g...
Araújo, Samuel; Viseu, Floriano; Soares, Ana Jacinta; Leite, IsabelLa relevancia de aplicar lo aprendido en matemáticas a situaciones cotidianas en el aprendizaje de alumnos nos ha llevado a desarrollar un experimento sobre la enseñanza de la función logarítmica mediante tareas de modelización. A partir de este experimento, pretendemos caracterizar las actividades de alumnos de 12º curso, en la realización de tareas de modelización relativas a temas de funciones logarítmicas u...
