Summary: Nano-sized PS-MFI, ETS-10 and SAPO-34 zeolites were used as CO2-selective fillers in high-performance mixed-matrix carbon molecular sieve membranes for CO2/N-2 separation. The in-house polyimide precursor ODPA-TMPDA was employed for the membranes, leading to improved gas permeability. Zeolite-filled CMSMs showed enhanced CO2 permeability and selectivity, especially with SAPO-34 outperforming the Robeson upper bound for CO2/N-2 separation.

Summary: This study fabricated symmetric mixed-matrix membranes by employing zeolite A-3 dispersed in a polyether sulfone (PES) matrix through solution casting technique. The impacts of zeolite loading and annealing temperatures on thermal stability, morphology, and carbon capture performance of the membranes were systematically investigated. Compared to the pristine PES membrane, the incorporation of 30 wt% optimal zeolite loading into the polymer matrix enhanced the CO2 permeability from 81 to 128 Barrer, and the CO2/N2 selectivity from 9 to 22. Annealing the composite membranes at 155 degrees C further improved the CO2 permeability, but at the expense of reduced CO2/N2 selectivity.

Summary: Mixed-matrix formulation is a promising method to improve the performance of polymer membranes with the incorporation of fillers. In this work, the effect of filler structural integrity on the separation performance of mixed-matrix membranes was explored. Different sizes of SAPO-34 zeolite fillers were incorporated into 6FDA-DAM polyimide and it was found that the micron as-synthesized and submicron as-synthesized fillers enhanced CO2/CH4 separation, while the submicron ground filler decreased CO2 permeability. The balance between structural integrity and crystal size of the filler is crucial for high-performing mixed-matrix membranes.

Summary: Carbon-based membranes were synthesized on porous alumina via a hydrothermal method from aqueous glucose solutions. The hydrothermal treatment time and temperature were evaluated to study their effects on the microstructure of the membranes. The obtained carbon membranes were found to be deposited both on the surface and in the interiors of the porous alumina. The carbon membrane prepared at a hydrothermal treatment of 200 degrees C for 5 hours showed few pinholes and consisted of amorphous carbon with hydroxy groups. Gas transmission rate measurements indicated that the membrane had a pore size of approximately 0.3 nm and exhibited high selectivity for various gas mixtures.

Summary: Manipulation of heating rate during the fabrication of PI/NCC-based carbon membranes has a significant impact on gas permeation, with different heating rates leading to variations in membrane ideal selectivity and permeability. A heating rate of 3°C/min showed an improvement in membrane ideal selectivity but a reduction in permeability.

Summary: This research used hydrous manganese oxide (HMO) nanoparticles in polyvinylidene fluoride (PVDF) to enhance the ability of mixed matrix membranes (MMM) to separate oil/water emulsions by improving hydrophilicity and oleophobicity. The presence of -OH groups and Mn element in the PVDF/HMO membrane affected wetting properties, leading to better water affinity and oil aversion. The PVDF/HMO membrane with 10% HMO loading exhibited a significantly higher water flux and oil rejection rate compared to pristine PVDF membranes.

Summary: A continuous adsorption analysis for the removal of sodium ions from seawater using synthesized zeolite A was conducted in a fixed-bed column. The study investigated the effect of flow rate, sodium ion concentration, and zeolite bed height on the removal process. Breakthrough curve analysis was used to model the adsorption isotherm, and kinetic models including the Thomas, Adams-Bohart, and Yoon-Nelson models were used to analyze the particles' movement. The results showed that the breakthrough capacity decreased with increasing flow rate and decreasing sodium ion concentration, while it increased with increasing bed height. The Adams-Bohart model demonstrated better performance in describing the kinetic behavior compared to the other models. The study highlights the potential use of zeolite A in desalination processes for extracting sodium ions from seawater.

Summary: Damage resistance of carbon fibre reinforced composites is crucial and can be improved by modifying the epoxy matrix with amine functionalized multi walled carbon nanotubes. Laminates with different nanotube concentrations were fabricated and showed enhanced load bearing capacity, toughness and damage resistance. Matrix cracking was suppressed and delamination area was reduced. The improvement in damage resistance was attributed to the interfacial interactions and energy absorbing microstructure.
