A biologically inspired hydrophobic membrane for application in pervaporation
Nora, Jullok; Martínez, Rodrigo; Wouters, Christine; Luis, Patricia; Sanz, María Teresa; Bruggen, Bart Van der (American Chemical Society, 2013-02)An artificial polydimethylsiloxane/polyphenylsulfone (PDMS/PPSU) membrane, which emulates the hydrophobic behavior of natural membranes, was synthesized. Hydrophobicity was achieved by coating the membrane surface sublayer ... -
A cascaded pervaporation process for dehydration of acetic acid
Nora, Jullok; Luis, Patricia; Degrève, Jan; Van der Bruggen, Bart (Elsevier, 2014-02)Pervaporation is advantageous in separating close-boiling point mixtures, azeotropes, thermally sensitive compounds and purification of chemicals. However, one pervaporation unit may not be economically feasible to ... -
Effect of impurities in the recovery of 1-(5-bromo-fur-2-il)-2-bromo-2-nitroethane using nanofiltration
Martínez, Martina Brito; Nora, Jullok; Negrín, Zenaida Rodríguez; Bruggen, Bart Van der; Luis, Patricia (Elsevier B.V., 2013-08)The recovery of the active pharmaceutical ingredient 1-(5-bromo-fur-2-il)-2-bromo-2-nitroethane (denoted as G-1) from residual ethanol produced during the purification of G-1 was studied by using solvent resistant ... -
A Green Approach to Modify Surface Properties of Polyurethane Foam for Enhanced Oil Absorption
Zhi, Chien Ng; Rosyiela Azwa, Roslan; Woei, Jye Lau; Gürsoy, Mehmet; Mustafa, Karaman; Nora, Jullok; Ahmad Fauzi, Ismail (MDPI AG, 2020-08)The non-selective property of conventional polyurethane (PU) foam tends to lower its oil absorption efficiency. To address this issue, we modified the surface properties of PU foam using a rapid solvent-free surface ... -
Membrane crystallization for the recovery of a pharmaceutical compound from waste streams
Brito Martínez, M.; Nora, Jullok; Rodríguez Negrín, Z.; Van der Bruggen, B.; Luis, P. (Elsevier, 2014-02)The recovery of the active pharmaceutical compound 1-(5-bromo-fur-2-il)-2-bromo-2-nitroethane (denoted as G-1) in a crystalline form from waste aqueous solutions using membrane crystallization is addressed in this work. ... -
Nano-WS2 embedded PES membrane with improved fouling and permselectivity
Jiuyang, Lin; Ruixin, Zhang; Wenyuan, Ye; Nora, Jullok; Sotto, Arcadio; Bruggen, Bart Van der (Elsevier Inc., 2013)The application of nanoparticles as additives in membrane synthesis for improving the resistance of membranes against fouling has triggered recent interest in new membrane types. However, most nanoparticle-enhanced membranes ... -
P-recovery as calcium phosphate from wastewater using an integrated selectrodialysis/crystallization process
Anh T.K., Tran; Yang Zhang; Dominik, De Corte; Jan-Bart, Hannes; Wenyuan Ye; Priyanka, Mondal; Nora, Jullok; Boudewijn, Meesschaert; Luc Pinoy; Bart Van der, Bruggen (Elsevier, 2014)A promising and sustainable renewable source of phosphate was obtained through crystallization of calcium phosphate from wastewater. The aim of the present study was to evaluate the feasibility of an integrated ... -
Pellet reactor pretreatment: A feasible method to reduce scaling in bipolar membrane electrodialysis
Tran, Anh Thu K; Nora, Jullok; Meesschaert, Boudewijn D.; Pinoy, Luc Jozef Jan; Van Der Bruggen, Bart (Elsevier Inc., 2013-07)This study aims to evaluate the feasibility of a pellet reactor in reducing the scaling potential in electrodialysis with bipolar membranes for water containing a high concentration of calcium by adding sodium carbonate ... -
Potential innovations in separation technology by nature-inspired membranes: Beneath and beyond the Earth's crust
Nora, Jullok (Society of Chemical Industry/Wiley, 2014-04)The understanding of complex bio-mechanisms in nature is explored in this perspective as a way to effectively enable scientific advancements in membrane technology. The mechanisms of nature-inspired technological improvements ...
