1. Tunable retention and recovery via pore-to-particle interactions in amine functionalized micro- and ultrafiltration Membranes: Towards scalable viral vector purification.
PMID:日期:2025-11-03Membrane-based technology is a cornerstone of bioprocessing and nanoparticle separation, yet the relationship between membrane pore size and particle retention or transmission remains poorly standardized across applications. This study systematically investigates the role of the pore-to-particle size ratio ( ) in determining membrane performance, integrating literature data with controlled filtration experiments using model nanoparticles, proteins, and virus-like particles. We demonstrate that high retention (≥95 %) occurs consistently at across both microfiltration and ultrafiltration regimes; however, flux stability varied widely with , offering minimal flux decline. As increases above 1, transmission dominates, but selectivity can be dramatically enhanced through membrane surface modification. Amine functionalization of the membrane pore with a hydrogel exhibited >70 % retention of 20 nm negatively charged particles even when and 80 % retention of DNA and protein when , highlighting the significant role of electrostatic interactions. Furthermore, modeling the prediction of flux decline and pore size reduction further validated the increased interactions via functionalization. Notably, these findings have implications for adeno-associated virus (AAV) purification: while conventional microfiltration membranes transmit AAV with minimal selectivity, functionalized membranes offer a potential route to selectively retain impurities without compromising vector recovery. Together, this work establishes a unified framework based on and demonstrates how targeted functionalization can expand the functional range of porous membranes. These results provide a mechanistic foundation for improved membrane selection and design, especially in applications requiring high-resolution particle separation, such as gene therapy manufacturing.

2. Volatile fatty acid selectivity during electrodialysis: effect of a competing counterion on volatile fatty acid transport mechanisms.
2. 电渗析过程中挥发性脂肪酸的选择性：竞争性反离子对挥发性脂肪酸传输机制的影响PMID:日期:2025-09-16Volatile fatty acids (VFAs) are short-chain carboxylic acids with versatile applications that can be sustainably produced through anaerobic digestion. VFAs must be separated from anaerobic digestate for downstream use. Electrodialysis (ED) is an approach to selectively separate anionic VFAs from other ions, water, and neutral solutes. Towards enhancing selective VFA separation, VFA transport mechanisms during ED need to be understood. Accordingly, our objectives were to (i) determine the relative contributions of the partition and mobility selectivities to the permeability selectivity for VFA-containing counterion pairs, and (ii) determine the effect of a competing counterion on VFA transport mechanisms. To do this, we evaluated the permeability (P/P), partition (K/K), and mobility (u/u) selectivities of six VFA-containing counterion pairs, including VFA/VFA and VFA/Cl pairs, and a chloride (Cl)/bromide (Br) control under (i) mixed- and (ii) single-counterion conditions. Results showed the partition selectivity drove the permeability selectivity for Cl/VFA and Cl/Br pairs while the mobility selectivity drove the permeability selectivity for VFA/VFA pairs. Further, for the VFA/Cl and Cl/Br pairs, we observed lower mixed-counterion partition selectivities and higher mixed-counterion mobility selectivities than corresponding single-counterion selectivities. Conversely, for the VFA/VFA pairs, we observed generally lower mixed-counterion partition mobility selectivities than single-counterion selectivities. Overall, results indicate that VFA partitioning decreased by the presence of a counterion with greater affinity for the membrane while the effect of the competing counterion on VFA mobility depended on the competing counterion physicochemical properties. This work provides mechanistic insights into electro-driven VFA transport under conditions with competing counterions which is critical given the complexity of digestates. This study is the first to systematically evaluate VFA transport properties and selectivities in an AEM and provides a robust experimental framework for determining electro-driven counterion permeabilities under mixed-counterion conditions.

3. Contribution of the transmembrane electric potential to the set voltage in a single-anion exchange membrane electrodialysis-cell and the role of solution conditions.
PMID:日期:2025-03-01The transmembrane electric potential (TMEP) drives ion transport via electromigration across ion exchange membranes (IEMs) during electrodialysis (ED). For ED operation, a voltage is either measured, or set to remain constant, between two electrodes on either side of a single IEM (simplified ED-cell) or a stack of IEMs (bench-scale ED system). The set/measured voltage has been used in the literature to approximate the TMEP in simplified ED-cells assuming that other elements between the electrodes (e.g., solutions, boundary layers, concentration gradient) contribute negligibly to the measured/set voltage; however, there is no experimental evidence in the literature comprehensively evaluating the accuracy of this assumption. Accordingly, our objectives were to (i) determine the contribution of the TMEP to the set voltage in a simplified ED-cell under operationally relevant solution conditions, and (ii) understand the role of solution conditions on the potential drop contributions from each element between reference electrodes. We studied sodium salts of eight anions (inorganic and organic) and three desalination levels at a set voltage of 0.4 V. Results showed that the set voltage was not a good approximation of the TMEP for any solution condition which was primarily attributed to the substantial potential drop from the solutions. The TMEP also varied substantially depending on solute identity and concentration. Additionally, the TMEP decreased substantially as the desalination level increased from 0% to 75%, which was attributed to the increase in potential drops due to the boundary layers and open circuit voltage. The reported findings provide important insights into the effective driving force of ion transport via electromigration when operating ED at a set voltage.

4. Relative contributions of mobility and partitioning to volatile fatty acid flux during electrodialysis.
PMID:日期:2024-08-12Economically valuable volatile fatty acids (VFAs) are sustainably produced via fermentation processes. To use VFAs downstream, they must be recovered using technologies like electrodialysis (ED). Solute transport properties (i.e., partition coefficient (K), diffusion coefficient (D), and permeability (P=KD)) govern flux in ED. Therefore, to advance understanding of VFA flux through anion exchange membranes (AEMs) in ED, we aimed to elucidate the relative contributions of VFA partitioning and mobility to their flux. Accordingly, for VFAs of different sizes (C1-C5) and inorganic anions (Cl, Br), we measured their fluxes during ED, permeabilities, and partition coefficients, and calculated the diffusion coefficients. We then evaluated the correlations between flux and transport properties and between transport properties and anion physicochemical properties. Results showed VFA flux had a strong correlation with permeability (R=0.94, <0.01), consistent with flux described by the Nernst-Planck equation. Further, while there was a negative correlation between VFA flux and partition coefficient (R=0.46, =0.21), there was a positive correlation between VFA flux and diffusion coefficient (R=0.95, <0.01) which showed VFA mobility governed VFA flux. We observed a negative correlation between VFA diffusion coefficient and carbon-chain length which was attributed to steric hindrance, and a positive correlation between partition coefficient and carbon chain-length which we attributed to hydrophobicity and polarizability. This work provides fundamental insight on interactions between VFAs and AEMs which affect anion flux during ED.

5. Correlating the Diffusion of Water to Performance in Model Reverse Osmosis Polyamides with Controlled Crosslink Densities.
5. 将水的扩散与具有可控交联密度的模型反渗透聚酰胺的性能相关联PMID:日期:2023-07We systematically reduce the cross-link density of a PA network based on m-phenylene diamine by substituting a fraction of the trifunctional trimesoyl chloride cross-linking agent with a difunctional isophthaloyl analog that promotes chain extension, in order to elucidate robust design cues for improving the polyamide (PA) separation layer in reverse osmosis (RO) membranes for desalination. Thin films of these model PA networks are fully integrated into a composite membrane and evaluated in terms of their water flux and salt rejection. By incorporating 15 mol % of the difunctional chain extender, we reduce the cross-link density of the network by a factor of two, which leads to an 80 % increase in the free or unreacted amine content. The resulting swelling of the PA network in liquid water increases by a factor of two accompanied by a 30 % increase in the salt passage through the membrane. Surprisingly, this leads to a 30 % decrease in the overall permeance of water through the membrane. This conundrum is resolved by quantifying the microscopic diffusion coefficient of water inside the PA network with quasi-elastic neutron scattering. In the highest and lowest cross-link density networks, water shows strong signatures of confined diffusion. At short length scales, the water exhibits a translational diffusion that is consistent with the jump-diffusion mechanism. This translational diffusion coefficient is approximately five times slower in the lowest cross-linked density network, consistent with the reduced water permeance. This is interpreted as water molecules interacting more strongly with the increased free amine content. Over longer length scales the water diffusion is confined, exhibiting mobility that is independent of length scale. The length scales of confinement from the quasi-elastic neutron scattering experiments at which this transition from confined to translational diffusion occurs is on the order of (5 to 6) , consistent with complementary X-ray scattering, small angle neutron scattering, and positron annihilation lifetime spectroscopy measurements. The confinement appears to come from heterogeneities in the average inter-atomic distances, suggesting that diffusion occurs by water bouncing between chains and occasionally sticking to the polar functional groups. The results obtained here are compared with similar studies of water diffusion through both rigid porous silicates and ion exchange membranes, revealing robust design cues for engineering high-performance RO membranes.

6. Performance evaluation and model of spacesuit cooling by hydrophobic hollow fiber-membrane based water evaporation through pores.
6. 基于疏水性中空纤维膜孔隙水蒸发的航天服冷却性能评估与模型PMID:日期:2023-02-18A comprehensive mathematical model is presented that accurately estimates and predicts failure modes through the computations of heat rejection, temperature drop and lumen side pressure drop of the hollow fiber (HF) membrane-based NASA Spacesuit Water Membrane Evaporator (SWME). The model is based on mass and energy balances in terms of the physical properties of water and membrane transport properties. The mass flux of water vapor through the pores is calculated based on Knudsen diffusion with a membrane structure parameter that accounts for effective mean pore diameter, porosity, thickness, and tortuosity. Lumen-side convective heat transfer coefficients are calculated from laminar flow boundary layer theory using the Nusselt correlation. Lumen side pressure drop is estimated using the Hagen-Poiseuille equation. The coupled ordinary differential equations for mass flow rate, water temperature and lumen side pressure are solved simultaneously with the equations for mass flux and convective heat transfer to determine overall heat rejection, water temperature and lumen side pressure drop. A sensitivity analysis is performed to quantify the effect of input variability on SWME response and identify critical failure modes. The analysis includes the potential effect of organic and/or inorganic contaminants and foulants, partial pore entry due to hydrophilization, and other unexpected operational failures such as bursting or fiber damage. The model can be applied to other hollow fiber membrane-based applications such as low temperature separation and concentration of valuable biomolecules from solution.

7. Electrospun PVB/AVE NMs as mask filter layer for win-win effects of filtration and antibacterial activity.
7. 静电纺丝PVB/AVE纳米纤维膜作为口罩过滤层，实现过滤与抗菌活性的双赢效果PMID:日期:2023-02-09The COVID-19 pandemic has caused serious social and public health problems. In the field of personal protection, the facial masks can prevent infectious respiratory diseases, safeguard human health, and promote public safety. Herein, we focused on preparing a core filter layer for masks using electrospun polyvinyl butyral/apocynum venetum extract nanofibrous membranes (PVB/AVE NMs), with durable interception efficiency and antibacterial properties. In the spinning solution, AVE acted as a salt to improve electrical conductivity, and achieve long-lasting interception efficiency with adjustable pore size. It also played the role of an antibacterial agent in PVB/AVE NMs to achieve win-win effects. The hydrophobicity of PVB-AVE-6% was 120.9° whereas its filterability reached 98.3% when the pressure drop resistance was 142 Pa. PVB-AVE-6% exhibited intriguing properties with great antibacterial rates of 99.38% and 98.96% against and , respectively. After a prolonged usability test of 8 h, the filtration efficiency of the PVB/AVE masks remained stable at over 97.7%. Furthermore, the antibacterial rates of the PVB/AVE masks on and were 96.87% and 96.20% respectively, after using for 2 d. These results indicate that PVB/AVE NMs improve the protective performance of ordinary disposable masks, which has certain application in air filtration.

8. Dual-bionic nano-groove structured nanofibers for breathable and moisture-wicking protective respirators.
8. 双仿生纳米沟槽结构纳米纤维用于透气吸湿防护口罩PMID:日期:2022-12-29Coronavirus disease 2019 (COVID-19) pandemic makes protective respirators highly demanded. The respirator materials should filter out viral fine aerosols effectively, allow airflow to pass through easily, and wick away the exhalant moisture timely. However, the commonly used melt-blown nonwovens perform poorly in meeting these requirements simultaneously. Herein, dual-bionic nano-groove structured (NGS) nanofibers are fabricated to serve as protective, breathable and moisture-wicking respirator materials. The creativity of this design is that the tailoring of dual-bionic nano-groove structure, combined with the strong polarity and hydrophilicity of electrospinning polymer, not only endows the nanofibrous materials with improved particle capture ability but also enable them to wick away and transmit breathing moisture. Benefitting from the synthetic effect of hierarchical structure and the intrinsic property of polymers, the resulting NGS nanofibrous membranes show a high filtration efficiency of 99.96%, a low pressure drop of 110 Pa, and a high moisture transmission rate of 5.67 kg m d at the same time. More importantly, the sharp increase of breathing resistance caused by the condensation of exhaled moisture is avoided, overcoming the bottleneck faced by traditional nonwovens and paving a new way for developing protective respirators with high wear comfortability.

9. Biocompatible curcumin coupled nanofibrous membrane for pathogens sterilization and isolation.
9. 生物相容性姜黄素偶联纳米纤维膜用于病原体灭菌和隔离PMID:日期:2022-08-10Airborne transmission of pathogens is the most probable cause for the spread of respiratory diseases, which can be intercepted by personal protective equipment such as masks. In this study, an efficient antiviral personal protective filter was fabricated by coupling the biocompatible curcumin (CCM) with nanofibrous polytetrafluoroethylene (PTFE) membrane. The CCM extracted from plants was first dissolved in acidified ethanol at a certain pH and temperature to optimize its loading concentration, antiviral activation, and binding forces on the polyethylene terephthalate (PET) support to form a pre-filtration layer at the front section of the filter. Ultrathin PTFE membrane was then fabricated on the antibacterial-antiviral PET support (A-A PET) by controllable heating lamination. This functional layer of the filter exhibits good gas permeance (3423.6 m/(m·h·kPa)) and ultrafine particles rejection rate (>98.79%). Moreover, the obtained A-A filter exhibit a high antibacterial rate against a variety of bacteria ( and were 99.84%, 99.02%, 93.60%, 95.23%, respectively). Forthwith virucidal (SARS-CoV-2) efficiency of the A-A filter can reach 99.90% for 5 min. The filter shows good stability after 10 heating cycles, demonstrating its reusability.

10. Trends and errors in reverse osmosis membrane performance calculations stemming from test pressure and simplifying assumptions about concentration polarization and solute rejection.
10. 反渗透膜性能计算中源于测试压力以及对浓度极化和溶质截留率简化假设的趋势与误差PMID:日期:2022-08-05A primary goal in the design of reverse osmosis (RO) membranes is to improve water-solute selectivity and water permeance. These transport properties are commonly calculated in the literature using the solution-diffusion model with selectivity (, bar) defined as the ratio between water permeance (, L.m.h.bar) and solute permeance (, L.m.h). In calculating transport properties, researchers often use simplifying assumptions about concentration polarization (CP; i.e., assuming negligible CP or a certain extent of CP) and solute rejection (i.e., assuming solute rejection is approximately 1 to enable the explicit use of the CP modulus in solute permeance calculations). Although using these assumptions to calculate transport properties is common practice, we could not find a study that evaluated the errors associated with using them. The uncertainty in these errors could impede unequivocally identifying manufacturing approaches that break through the commonly plotted trade-off frontier between selectivity and water permeance ( vs. ); however, we did not find in the literature a study that quantified such errors. Accordingly, we aimed to: (1) quantify the error in transport properties (, , and ) calculated using common simplifying assumptions about CP and rejection; and (2) determine if using simplifying assumptions affects conclusions drawn about membrane performance or trends concerning the trade-off frontier. Results show that compared with the case where no simplifying assumptions were made, simplified calculations were least accurate at low pressures for water permeance (up to 78% overestimation) and high pressures for solute permeance (up to 188% overestimation). Accordingly, the corresponding selectivities were least accurate at low pressure (up to 111% overestimation) and high pressure (up to 66% underestimation), and conclusions drawn about membrane performance and trade-off trends were pressure-dependent. Importantly, even in the absence of simplifying assumptions, selectivity results were pressure-dependent, indicating the importance of standardizing test conditions for the continued use of current performance metrics (i.e., and ). We propose a two-pressure approach-collecting data for and at a high and a low pressure, respectively-combined with simplifying assumptions for more accurate simplified estimations of selectivity (< 10% absolute error). Our work contributes to a better understanding of the effects of operating pressure and key simplifying assumptions commonly used in calculating RO membrane performance metrics and interpretation of corresponding results.
