“…Currently, these processes are predominantly dependent on heat-based operations. Membrane technology, which has seen extensive application in the chemical industry, provides clear benefits for the concentration of heat-sensitive substances. , This technology has the potential to progressively supplement or even replace traditional energy-intensive processes across various sectors. To enable this transformation, there is a need for superior membranes that are more stable and selective .…”

An extensive amount of research has been devoted to the design and fabrication of solvent-resistant nanofiltration (SRNF) membranes. In the present research, a semi-interpenetrating polymer network (semi-IPN) system, which is based on poly(ether sulfone) (PES) and nitrogen-rich compounds, was utilized to fabricate SRNF membranes via click reactions. Specifically, the polymer N-rich-p (alkyne) and cyanuric triazide (CC-N 3 ) were synthesized from cyanuric chloride and subsequently integrated as cross-linking agents into the PES membrane matrix. The morphology and structure of the fabricated membranes were comprehensively examined with multiple methods such as attenuated-total-reflectance Fourier transform infrared, NMR, X-ray photoelectron spectroscopy, atomic force microscopy, and field-emission scanning electron microscopy. Thermal properties examined through thermogravimetric analysis and mechanical attributes including tensile strength showed a notable enhancement compared to the original membrane. The fabricated membranes demonstrated superior stability in solvents like methanol (MeOH), ethanol (EtOH), trichloromethane (CHCl 3 ), tetrahydrofuran (THF), and N,N-dimethylformamide (DMF). Performance evaluations, encompassing solvent permeance, contact angle, porosity assessment, and dye rejection tests, indicated that an increase in cross-linking agents led to improved resistance against organic solvents. Furthermore, the performances of the prepared cross-linked membranes in rejecting dyes Reactive Red, Methylene Blue,

“…Among the commercial membrane elements, polymeric membranes are the most popular, but disadvantages such as short lifetime and fouling still encourage scientists to look for alternatives (Jarvis et al 2022). Comparison of polymer and ceramic membranes shows that the lifetime of ceramic membranes is 2-3 times longer than that of polymer membranes (Cheng et al 2022;Aristizábal et al 2023;Hofs et al 2011).…”

The article is devoted to the synthesis of ceramic membranes based on silicon carbide and the study of their mechanical, electrical, and antibacterial properties. SiC-based ceramic membranes have a few advantages, namely high surface hydrophilicity, good water permeability and negative surface charge, which leads to better performance during their operation. The effect of carbonate type and addition of liquid glass on the physicochemical properties of ceramic membranes was investigated using diffraction analysis and scanning electron microscopy. It was found that regardless of the carbonate type, only two phases can be identified: the main phase in the original mixture is silicon carbide and an additional phase added to the mixture is corundum. The transport properties obtained (9.03–18.66 cm3/(min·cm2)), and the results of electron microscopy indicate the macroporosity of ceramic membranes based on silicon carbide (13–20 µm). Ceramic membranes of high strength (16.3–46.8 MPa) were obtained. Studies on antibacterial properties have shown that SiC-based ceramic membranes do not exhibit antibacterial properties. The additional modification of ceramic membranes with titanium oxide has given ceramic membranes based on silicon carbide antibacterial properties, as evidenced by the inhibition of the growth of gram-negative bacteria, the effectiveness of which depends on the number of selective layers based on TiO2 applied. The results of this study are useful to enrich the knowledge of the production of silicon carbide membranes and are aimed at the future research and development of selective membranes (micro- and ultrafiltration) based on them.

“…Works [9,10] devoted to the study of the dissolution and precipitation of cellulose show that this changes the crystal structure of the polysaccharide. The use of ionic liquids to dissolve cellulose can also be used for the preparation of membranes [11,12]. As a natural membrane, cellulose residue meets all the requirements for natural resources.…”

Like all raw materials of plant origin, persimmon fruits are considered a material rich in carbohydrates. This subtropical plant grows almost throughout the entire territory of the Republic of Azerbaijan. Despite the widespread distribution of this plant in the republic, very few types of products are produced from it. The main reason why persimmon fruits are not used effectively from a production point of view is that they have astringent properties. Since fruit carbohydrates play an important role in eliminating the tart taste of persimmons, the study of the carbohydrate complex was considered as a basic condition. After fractionation of carbohydrates with a water-alcohol mixture, certain stresses arise in the filter residue, which consists of cellulose-lignin. These stresses are analyzed using tensors. It has been established that the size of the filter pores is about 0.005÷0.05 microns, and the volume of these pores is 0.062÷0.195 cm3/g. The clearance coefficient averaged 19.97 %. It is known that the outer layer of a plant cell consists of cellulose and other structural compounds. These substances determine the porosity of the material. The mass fraction of the final product of the fractional residue, more precisely cellulose, averaged 0.63 %. The use of the resulting filter membrane in the clarification of fruit juices has shown its usefulness in industry. It has been established that the selectivity of these membranes for various amino acids is 5÷18 %, and for minerals 1÷30 %. The lipid resistance of the membranes was high. It should be noted that cellulose has the ability to restore its structure and at the last stage acts only as a filter membrane. This explains the usefulness of the cellulose-lignin mixture as a membrane material
