“…characterized the fibril formation in cowpea, chickpea, and lentil proteins by using AFM, and evaluated the changes in the fibril's dimensions at different heat treatment times as a function of the height and contour length of the images. The characterization of the surface of proteins aggregates could be related to their capacity to interact with other compounds such as water or oil (Bildyukevich et al, 2020;Wen et al, 2020). In this work, the smallest microparticles were obtained at pH 9 (Figure H7) and 3 MF cycles and were more stable due to water-protein interactions.…”

“…It was previously shown that when Fe-BTC is embedded into the ChS interlayer, agglomerates of Fe-BTC appear on the surface of the membrane selective layer ( Figure 3 and Figure 4 ), which leads to a substantial increase in surface roughness ( Figure 5 and Figure 6 ; Table 3 ) and a slight increase in water contact angle (from 30 ± 2° to 36 ± 2°) ( Figure 7 ) of the selective layer surface [ 83 ]. It is commonly known that the contact angle also depends on the surface roughness parameters, along with the chemical nature of the surface [ 87 ].…”

Thin-film composite m embranes (TFC) obtained by the formation of a selective layer on a porous membrane-substrate via interfacial polymerization (IP) are indispensable for separation procedures in reverse osmosis, nanofiltration, pervaporation, and gas separation. Achieving high selectivity and permeability for TFC membranes is still one of the main challenges in membrane science and technology. This study focuses on the development of thin film nanocomposite (TFN) membranes with a hierarchically structured polyamide (PA)/chitosan succinate (ChS) selective layer embedded with a metal–organic framework of iron 1,3,5-benzenetricarboxylate (Fe-BTC) for the enhanced pervaporation dehydration of isopropanol. The aim of this work was to study the effect of Fe-BTC incorporation into the ChS interlayer and PA selective layer, obtained via IP, on the structure, properties, and performance of pervaporation TFN membranes. The structure and hydrophilicity of the developed TFN membranes were investigated using scanning electron microscopy (SEM) and atomic force microscopy (AFM), along with water contact angle measurements. The developed TFN membranes were studied in the pervaporation dehydration of isopropanol (12–30 wt % water). It was found that incorporation of Fe-BTC into the ChS interlayer yielded the formation of a smoother, more uniform, and defect-free PA ultrathin selective layer via IP, due to the amorpho-crystalline structure of particles serving as the amine storage reservoir and led to an increase in membrane selectivity toward water, and a slight decrease in permeation flux compared to the ChS interlayered TFC membranes. The best pervaporation performance was demonstrated by the TFN membrane with a ChS-Fe-BTC interlayer and the addition of 0.03 wt % Fe-BTC in the PA layer, yielding a permeation flux of 197–826 g·m−2·h−1 and 98.50–99.99 wt % water in the permeate, in the pervaporation separation of isopropanol/water mixtures (12–30 wt % water).

“…The process of inversion involved a two-phase conversion of the homogeneous PS solution, one of which is a solid phase; it was rich in the polymer and formed the membrane. A liquid phase is another one; it produced pores [37][38][39][40][41][42][43].…”

Assessment of green biodiesel production based on Egyptian waste cooking oil using different porous membranes

In this study, green biodiesel was produced from Egyptian waste cooking oil by trans-esterification reaction using membrane technology. The produced biodiesel was characterized by physicochemical properties, FTIR, and gas chromatography/mass spectrometry (GC/MS). It was found that it meets the specifications of the American standard test method (ASTM) D6751. Because glycerol was the only impurity that was difficult to separate from the prepared biodiesel by regular methods, polysulfone (PS) membrane and three hybrid membranes were prepared using the phase inversion method for the glycerol purification process. The hybrid membranes were prepared by mixing PS with different weight ratios of polyethylene glycol (PEG), polyvinyl pyrrolidone (PVP), and zinc oxide nanoparticles (ZnO NPs). The structure and surface morphology of the resulted membranes were characterized by scanning electron microscope (SEM), Fourier-transform infrared spectroscopy (FTIR), and thermal gravimetric analysis (TGA). The purification efficiency of these membranes was satisfied by highperformance liquid chromatography (HPLC) and weight loss ratio. The HPLC chromatogram showed that the membrane of the PS/ZnO NPs provided the highest separation rate of the biodiesel by-product glycerol compared to the other ones.
