Summary: In this study, a new approach of space-confined sol-gel was proposed to regulate the size and distribution of the pores of a polyamide composite membrane, resulting in enhanced fraction efficiency. The introduction of TEOS into the porous polyamide network allowed the formation of a polyamide-silica based separation layer with decreased pore size and homogenized pore size distribution. The desired polyamide-silica based membrane showed improved glucose rejection and better efficiency in the removal of sodium sulfate from concentrated brine compared to the commercial membrane NF270.

Summary: In this work, post-treatment sol-gel methods using acidic and alkaline TEOS solutions were applied to refine the porous network of ZrO2 coating and improve corrosion resistance. The alkaline TEOS solution resulted in the formation of a dense SiO2 interlayer and narrowed pores in the coating, providing the best barrier performance. On the other hand, the acidic TEOS solution mainly formed thin SiO2 layers on the ZrO2 coating surface, leading to poor barrier performance due to electrostatic repulsion forces.

Summary: In order to prevent structural changes in nanofiltration membranes during operation, pre-compaction of the membranes is commonly performed. However, the NF270 membrane still shows pressure susceptibility in pure water systems even after pre-compaction, particularly at low pressures. This study provides experimental evidence for the effect of salinity on the pressure susceptibility of the NF270 membrane. The permeability of the membrane decreases with increasing salinity up to 189 mM MgSO4, with the largest reduction observed at the lowest MgSO4 concentration of 31.49 mM. The membrane susceptibility also significantly reduces with the introduction of 31.49 mM MgSO4. A mathematical expression developed for pure water systems, taking into account salinity effects, fits the experimental data well up to a concentration of 0.2 M. These results suggest that compaction of the membrane polymer occurs due to charge neutralisation or electric double layer compression, or both, but further increases in salinity have no significant effect on membrane susceptibility.

Summary: Various non-hydrolytic sol-gel synthesis methods were investigated to selectively produce mesoporous t-ZrO2 or m-ZrO2 with significant specific surface areas. The presence of significant amounts of water favored the formation of m-ZrO2, while strictly non-hydrolytic routes favored the formation of t-ZrO2. The role of water in the structure of zirconia was found to be crucial.

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: The construction of 2D Janus biointerfaces and 3D enteric biomaterials was achieved through the self-adaptation of 1D protein-polysaccharide nanostructures at the oil-water interface. These biomaterials consist of a protein dermis that accommodates oil droplets as a reservoir for bioactive compounds, and a polysaccharide epidermis that protects them from gastric degradation. The retention time of a bioactive cargo in the intestinal tract can be controlled by adjusting the thickness of the epidermis. This study highlights the importance of skin-inspired construction of enteric biomaterials using self-adaptation of 1D nanostructures at the oil-water interface, which can be tailored for specific therapeutic efficacies in intestinal treatments.

Summary: Ceramic nanofiltration (NF) membranes are efficient for purifying high-quality fructooligosaccharides (FOS), and the screening process should consider retention rate, yield, purity, membrane flux, and washing water volume. The concentration of FOS feed should be controlled within 100 g/L, and the suggested settings for transmembrane pressure, cross-flow velocity, and operating temperature are 0.7 MPa, 1.2 m/s, and 60 ℃, respectively. High separation factor and low non-prebiotic sugar rejection rate of the ceramic NF membrane can achieve high FOS yield and purity with less leachate addition. Moreover, the ceramic NF membrane maintains stable separation performance and can recover pure water flux after cleaning, showing promising application prospects in the FOS purification industry.

Summary: This study investigated the application of ceramic membranes in the separation and purification of simulated fermentation broth. The results showed that ceramic microfiltration and ultrafiltration membranes can both be used to clarify the broth, but the ultrafiltration membrane has a higher protein rejection rate. A smaller pore size in the ceramic ultrafiltration membrane effectively prevents pore channel pollution, resulting in a higher permeation flux during filtration of the broth.

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.
