Summary: A high-efficiency alpha-alumina ultrafiltration membrane was fabricated through co-sintering a gel layer with a pre-sintered interlayer. The use of a pre-sintered interlayer with rigidity and low roughness facilitated the preparation of a defect-free and ultra-thin separation layer. The prepared alpha-alumina ultrafiltration membrane had a thickness of only 140 nm, pure water permeability of 230 L m-2h-1 bar-1, and an average pore size of approximately 7 nm. It exhibited high rejection rates (>99%) and permeabilities (60-212 L m-2h-1 bar-1) in the separation of polyvinyl alcohol wastewater and the removal of Congo red dye, respectively.

Summary: Traditional oxide ceramics are brittle and sensitive to defects, which makes them prone to failure under stress. Electrospinning technology has been used to transform these ceramics from brittle to flexible by fibrillation and refinement of fiber diameter. A self-templated electrospinning strategy is proposed to synthesize oxide ceramic nanofibers without organic polymer template, resulting in nanofibers with high strength and toughness. This work provides a new strategy to develop strong and tough oxide ceramic materials.

Summary: High-performance asymmetric ceramic membranes are promising for wastewater treatment, but their large-scale production and application are hindered by high production costs. In this study, a simple and cost-effective co-pressing and co-sintering method was proposed to overcome the bottleneck of preparing thin defect-free asymmetric ceramic membranes. The membranes prepared using this method exhibited high water permeance, permeability, selectivity, and excellent fouling resistance and regeneration performance. This study demonstrates the potential of co-pressing and co-sintering for fabricating high-performance and cost-effective ceramic membranes.

Summary: Silica-coated titanium nitride (TiN/SiO2) particles were synthesized using a sol-gel method and the hardness of the sintered bodies fabricated with these particles was evaluated. The presence of few micropores in the TiN/SiO2 structure resulted in particles with small specific surface areas. The Vickers hardness increased in the order: TiN < TiN-SiO2 < TiN/SiO2A < TiN/SiO2S. The SiO2 shell acted as a sintering aid and the NaOH catalyst improved the density and hardness of the sintered body.

Summary: The study developed a facile method for constructing a functional surface on an alumina membrane substrate for antiparticle or antidust adhesion during exhaust-gas desulfurization. A PTFE coating with low surface energy, low surface roughness, and a low coefficient of friction was applied to reduce foulant adhesion and facilitate release, while maintaining excellent membrane absorption performance for SO2 absorption. In testing, the PTFE-coated membrane exhibited resistance to particle adhesion in a dusty environment, indicating its potential for gas absorption in such conditions.

Summary: In this study, a rigorous 3D model without geometry simplification was proposed and validated with experimental data for simulating CO2 capture in real membrane contactors. Additionally, a hybrid model was highlighted where two correction factors were introduced to a 2D model to approximate the results of the 3D simulation. These correction factors were correlated with dimensionless fluid dynamic parameters to characterize the geometry effects on flowing fluids. The hybrid modeling contributes to characterizing the influence of geometry on CO2 capture performance and improving computation accuracy-efficiency combinations.

Summary: A V-shaped punched baffle (VSPB) is developed to enhance fluid mixing in a stirred tank. Experimental results show that VSPB reduces mixing time by a maximum of 23% and 14.7% compared to standard baffles (SB) and standard punched baffles (SPB) at low speeds. Simulation results demonstrate that the punched baffle significantly increases fluid velocity and turbulence in the baffle region, forming tiny vortices.

Summary: The stiffness of phenolic resins is affected by methylene bridges and branched phenolic rings. Introducing naphthols does not significantly improve stiffness due to the counterbalance between nonbonded energies and the decrease in methylene bridges. In the case of cyanate ester modified phenolic resins (CEPF), chain-to-chain bridges of triazine rings increase the Young's modulus and contribute more to stiffness compared to rigid naphthols. The trend from plastic to cured state can be observed in the mean squared displacement and Young's modulus. These findings support the molecular design of phenolic resins to optimize stiffness.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
