Nanoparticle concentration and solvent exchange via organic solvent ultrafiltration Ozcelik, Feyza; Çulfaz Emecen, Pınar Zeynep (2025-02-19) Downstream processing of nanoparticles after synthesis frequently involves purification, concentration and solvent exchange steps. While these are typically done via centrifugation in lab scale, ultrafiltration is a practi...
Open and FAIR data for nanofiltration in organic media: A unified approach Van Buggenhout, Simon; et. al. (2025-01-01) Organic solvent nanofiltration (OSN), also called solvent-resistant nanofiltration (SRNF), has emerged as a promising technology for the removal of impurities, recovery of solutes, and the regeneration of solvents in vario...
Formation of cellulose nanocrystal membranes by controlled deposition Kocaman, Ceren; İçten, Berk Can; Büküşoğlu, Emre; Çulfaz Emecen, Pınar Zeynep (2024-09-08)
Cross-Linked Cellulose Nanocrystal Membranes with Cholesteric Assembly İçten, Berk Can; Büküşoğlu, Emre; Çulfaz Emecen, Pınar Zeynep (2024-06-25) Forming membranes by tangential flow deposition of cellulose nanocrystal (CNC) suspensions is an attractive new approach to bottom-up membrane fabrication, providing control of separation performance using shear rate and i...
Controlling Cellulose Membrane Performance via Solvent Choice during Precursor Membrane Formation Tekin, Fatma Seden; Çulfaz Emecen, Pınar Zeynep (2023-03-10) Fabrication of cellulose membranes by alkaline hydrolysis of cellulose acetate (CA) membranes is a simple alternative method to preparing cellulose membranes via phase inversion from their ionic liquid solutions. In this s...
Tuning electrostatic interactions for controlled structure and rejection of cellulose nanocrystal membranes Kocaman, Ceren; Büküşoğlu, Emre; Çulfaz Emecen, Pınar Zeynep (2022-11-05) © 2022 Elsevier B.V.Precise control over membrane performance by tuning fabrication parameters is highly desirable. We developed ultrafiltration membranes by depositing cellulose nanocrystals (CNCs) on a porous support via...
Solvent recovery from photolithography wastes using cellulose ultrafiltration membranes Savaş, Aygen; Çulfaz Emecen, Pınar Zeynep (2022-04-05) Solvent recycling and reuse are indispensable for ensuring a sustainable chemical industry and circular economy. In this study we report the fabrication of cellulose ultrafiltration membranes and their application in recov...
Fabrication of cellulose membranes via phase inversion using ionic liquids as solvents Durmaz, Elif Nur; Çulfaz Emecen, Pınar Zeynep (2022-02-21)
Use of stimuli-responsive polymeric microgels for fouling removal in membrane filtrations Aksoy, Canan; Kaner, Papatya; Aro, Grace; Asatekin, Ayşe; Çulfaz Emecen, Pınar Zeynep (2022-02-21)
Controlling Ultrafiltration Membrane Rejection via Shear-Aligned Deposition of Cellulose Nanocrystals from Aqueous Suspensions Kocaman, Ceren; Büküşoğlu, Emre; Çulfaz Emecen, Pınar Zeynep (2021-08-01) Cellulose nanocrystals (CNCs) of 180 nm length and 8 nm diameter were deposited on porous supports by tangential flow filtration followed by salt permeation to form ultrafiltration membranes. At a high enough shear rate on...
