Summary: The study systematically investigated the influence of charge density and ionic strength on the performance of nanofiltration membranes, revealing that low charge density limits polyelectrolyte adsorption and retention, while high charge density affects membrane surface charge and pure water permeability. Increasing ionic strength is crucial for high charge density polyelectrolytes, but has an opposite effect on membrane properties depending on the type of polyelectrolyte used.

Summary: Layer-by-layer assembly of polyelectrolyte layers is used to fabricate versatile nanofiltration membranes, with pH as a determinant factor in membrane formation and performance. By varying the pH, the charge density of polyelectrolyte layers can be adjusted, affecting salt retention and adsorption. Symmetric membranes with different pH levels (4, 8, and 9) and asymmetric membranes with a combination of base layers terminated by PEI/PSS layers are compared. The results show that increasing the pH leads to lower PEI charge density, causing higher adsorption. However, reducing charge density in symmetric membranes decreases salt retention, while asymmetric membranes consistently achieve >90% retention for MgSO4 and Na2SO4. The advantage of asymmetric membrane formation is demonstrated by the improved performance compared to symmetric membranes, with higher permeabilities and salt retentions (>95% for MgSO4 and Na2SO4). This pH-tailored assembly method allows for the production of versatile membranes with enhanced performance in terms of water flux and salt retention, without additional synthesis or modification steps.

Summary: Membrane-based beverage dealcoholization is a successful process for producing low- and non-alcoholic beer and represents a fast-growing industry. Polyamide NF and RO membranes are commonly applied for this process. Polyelectrolyte multilayer (PEM) NF membranes are emerging as industrially relevant species, with their unique properties underlining their importance in the food industry. Testing the tightest available commercial PEM NF membrane (NX Filtration dNF40) for beer dealcoholization showed that it is possible to achieve reasonable flux and alcohol removal with minimal permeance loss and extract loss.

Summary: A polypeptide modified polyelectrolyte nanofiltration membrane was fabricated using a novel brush assisted layer-by-layer assembly technology, resulting in a denser separation layer with an ultrathin thickness and a negatively charged surface. The membrane showed high rejections to potassium citrate and tetrasodium ethylenediamine tetraacetate, moderate rejection to sodium sulfate, and excellent antimicrobial property and fouling resistance. Chlorination treatment was found to optimize the membrane structure, enhance permeability, and maintain high salt rejection by increasing negative charge density and enlarging free volume between polyelectrolyte chains.

Summary: This study investigates the influence of molecular weight (Mw) on the performance of polyelectrolyte multilayer (PEM) membranes. The results show that Mw has different effects on the performance of different types of PEM membranes, especially for systems with higher polyelectrolyte (PE) mobility. Specifically, low-Mw PEM membranes exhibit the performance of a negatively charged separation layer, while high-Mw PEM membranes exhibit the performance of a positively charged separation layer. Additionally, low-Mw PEM membranes are denser than high-Mw PEM membranes. The pH stability of low-Mw PEM membranes is poorer, which may be attributed to their higher mobility.

Summary: The limitations of current thin film composite (TFC NF) membranes have led to an increasing demand for polyelectrolyte multilayer (PEM) membranes, which offer significant improvements in chemical resistance, fouling resistance, and selectivity. Laboratory experiments have shown that PEM membranes have higher selectivity, fouling resistance, and chemical stability than polyamide NF membranes. Additionally, PEM membranes have advantages for wastewater treatment, such as high selectivity, fouling resistance, chemical stability, and a wide range of cleaning methods.

Summary: Polyelectrolyte multilayers (PEMs) show promise as selective layers in nanofiltration (NF) due to their simplicity, controlled layer thickness, and versatility. Combining two different PEMs in an asymmetric structure allows further optimization. This study combines experimental filtration and theoretical models to describe the effective structure of an asymmetric PEM made of PAH/PSS and PAH/PAA. The obtained membrane properties suggest a distinct layer structure, and there is a fundamental difference in the retention of salt and polyethylene glycol molecules, attributed to different exclusion mechanisms.

Summary: In this study, polyamide and polyester thin-film composites (TFCs) and covalent organic frameworks (COFs) were fabricated as selective layers on a polyimide aerogel support for organic solvent nanofiltration (OSN) membranes. The polyimide aerogel support exhibited high stability and porosity, enabling high solvent flux. Both the experimental and predicted molecular weight cutoff (MWCO) values were obtained for the COFs and polyester TFC membranes. The operating temperature had minimal effect on the OSN performance.

Summary: We investigated targeted and localized material modifications produced by electropulsing on Al-capped Nb microbridges. The affected areas showed a decrease in work function, but little morphological change was observed. The extent of the modified regions was strongly influenced by terminal geometry, and modeling estimated a threshold temperature of 435 +/- 35 K for inducing material modifications. These findings provide insights into subtle modifications and progress in nanofabrication techniques.

Summary: The structure and electronic properties of Br layers on Ag(111) at different coverage were investigated using low-temperature scanning tunnelling microscopy, scanning tunnelling spectroscopy, and density functional theory calculations. It was found that the Br layers form a hexagonal (√3×√3)R30° structure with a coverage of around 0.3 monolayer, and a striped (6)(-1)(1)(2) structure with a coverage of around 0.4 monolayer. The study also revealed suppressed differential conductance for both structures at certain voltages, indicating the usefulness of Br layers in reducing the coupling between Ag(111) electrons and adsorbates.

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.
