AI Article Synopsis

  • A polycarbonate-polyether (PC-PE) polymer was created using solution or interfacial polymerization to make a dry diffusion membrane through a phase inversion method.
  • The membrane's strength and its ability to allow substances like chloride, phosphate, and vitamin B12 to pass through were tested.
  • By adjusting manufacturing factors, it was found that increasing the ultrafiltration rate and decreasing the membrane thickness both led to higher rates of substance diffusion through the membrane.

Article Abstract

Polycarbonate-polyether (PC-PE) polymer, prepared by solution or interfacial polymerization, was used to produce a dry PC-PE diffusion membrane by means of the phase inversion technique. The mechanical stabilities and diffusive permeabilities of chloride, phosphate and vitamin B12 were determined for this membrane. Additionally, close control over manufacturing parameters allowed the study of the effects of varied membrane thickness (at constant ultrafiltration rate) and varied ultrafiltration rate (at constant membrane thickness) on solute diffusive permeabilities. Both increased ultrafiltration rate and decreased thickness resulted in an increase in solute diffusive permeabilities.

We report on the design and fabrication of a novel circular pillar array as an interfacial barrier for microfluidic microphysiological systems (MPS). Traditional barrier interfaces, such as porous membranes and microchannel arrays, present limitations due to inconsistent pore size, complex fabrication and device assembly, and lack of tunability using a scalable design. Our pillar array overcomes these limitations by providing precise control over pore size, porosity, and hydraulic resistance through simple modifications of pillar dimensions.

Highly Permselective Contorted Polyamide Desalination Membranes with Enhanced Free Volume Fabricated by mLbL Assembly.

ACS Appl Mater Interfaces

Civil and Environmental Engineering Department, University of Houston, 4226 Martin Luther King Blvd, Houston, Texas 77204, United States.

The permeability-selectivity trade-off in polymeric desalination membranes limits the efficiency and increases the costs of reverse osmosis and nanofiltration systems. Ultrathin contorted polyamide films with enhanced free volume demonstrate an impressive 8-fold increase in water permeance while maintaining equivalent salt rejection compared to conventional polyamide membranes made with -phenylenediamine and trimesoyl chloride monomers. The solution-based molecular layer-by-layer (mLbL) deposition technique employed for membrane fabrication sequentially reacts a shape-persistent contorted diamine monomer with a trimesoyl chloride monomer, forming highly cross-linked, dense polyamide networks while avoiding the kinetic and mass transfer limitations of traditional interfacial polymerization.

Molecular Dynamics Insights into Water Transport Mechanisms in Polyamide Membranes: Influence of Cross-Linking Degree.

J Phys Chem B

January 2025

Engineering Research Center of Membrane and Water Treatment of MOE, College of Chemical and Biological Engineering, Zhejiang University, Hangzhou 310027, P. R. China.

Polyamide (PA) membranes are widely utilized in desalination and water treatment applications, yet the mechanisms underlying water transport within these amorphous polymer materials remain insufficiently understood. To gain more insight into these problems on a microscopic scale, we employ molecular dynamics (MD) simulations to analyze the relationship between the structural properties and the water permeation behavior of PA membranes. Two distinct atomistic models of PA membranes are developed by controlling their degrees of cross-linking (DC).

Purpose: Diffusion-weighted arterial spin labeling (DW-ASL) MRI has been proposed to determine the rate of water exchange (K) across the blood brain barrier (BBB). This study aims to further evaluate K MRI by comparing it with standard dynamic contrast-enhanced (DCE) MRI and histology in association with mannitol-induced disruption of the BBB.

Methods: DW-ASL was measured using a multiple b-value MRI protocol in normal rats at three post-labeling delays (N = 19), before and after intra-carotid injection of mannitol to disrupt BBB in one hemisphere (N = 13).
