“…As we know, any substance is stable in a potential range and undergoes a reduction or oxidation process more or less within this range [ 28 , 98 , 99 ]. That is why we can decompose (electrolyze) water to produce hydrogen and oxygen.…”

“…17 , there is enough space for lithium ions in this composition and it does not change volume, while even in graphite, some volume change is seen due to the entry and exit of lithium. Unlike the previous two anodes, lithium ions (not lithium atoms) are stored in this anode, and the oxidation reaction is due to the conversion of titanium to 3-valent titanium, not to a change in lithium capacity [ 28 , 74 , 75 , 131 ].…”

Improving the anode properties, including increasing its capacity, is one of the basic necessities to improve battery performance. In this paper, high-capacity anodes with alloy performance are introduced, then the problem of fragmentation of these anodes and its effect during the cyclic life is stated. Then, the effect of reducing the size to the nanoscale in solving the problem of fragmentation and improving the properties is discussed, and finally the various forms of nanomaterials are examined. In this paper, electrode reduction in the anode, which is a nanoscale phenomenon, is described. The negative effects of this phenomenon on alloy anodes are expressed and how to eliminate these negative effects by preparing suitable nanostructures will be discussed. Also, the anodes of the titanium oxide family are introduced and the effects of Nano on the performance improvement of these anodes are expressed, and finally, the quasi-capacitive behavior, which is specific to Nano, will be introduced. Finally, the third type of anodes, exchange anodes, is introduced and their function is expressed. The effect of Nano on the reversibility of these anodes is mentioned. The advantages of nanotechnology for these electrodes are described. In this paper, it is found that nanotechnology, in addition to the common effects such as reducing the penetration distance and modulating the stress, also creates other interesting effects in this type of anode, such as capacitive quasi-capacitance, changing storage mechanism and lower volume change.

“…In a separation process, different goals such as concentration, purification, separation, and displacement of the reaction balance can be considered. In this regard, membranes have been developed for the separation of various types of materials in solid, liquid, and gas states [30] . One of the most important factors is the type of polymer used in membrane fabrication.…”

Poly (vinylidene fluoride) (PVDF) and poly-sulfone (PSF) polymer solutions were made at a concentration of 18% by weight of the polymer as a non-soluble additive of polymer solution in 1-methyl-2-pyrrolidone (NMP) solvent. PVDF and PSF hollow fiber membranes were fabricated via the wet phase-inversion process. Fabricated membranes were characterized in terms of gas permeability, wetting resistance, water contact angle and overall porosity. In order to study the structure of the membranes made, the scanning electron microscopy images of the model (TM3000, HITACHI, Japan) were used. The morphology study indicates that the PSF membrane shows an open cross-section structure with smaller pore sizes. However, the PVDF membrane illustrates a thick sponge-like structure. The fabricated PVDF membrane shows higher wetting resistance, surface porosity, water contact angle, and N2 permeability. The performance of the produced membranes was examined for the Absorption of carbon dioxide in a gas-liquid contactor membrane through the solution of mono-ethanolamine (MEA). The results show that CO2 absorption flux of the PVDF hollow fiber membrane is higher than PSF hollow fiber membrane. The maximum CO2 absorption flux of 8.10 × 10-3 (mole/m2 s) at the liquid phase flow rate of 300 ml/min for PVDF hollow fiber membrane was achieved and also the maximum CO2 absorption flux of 6.50 × 10-3 (mole/m2 s) at the liquid phase flow rate of 300 ml/min for PSF hollow fiber membrane was obtained. It can be concluded that a porous hydrophobic hollow fiber membrane with high surface porosity and high gas permeability can be a productive alternative for CO2 absorption through gas-liquid membrane contactors.

“…Due to the rapid development of membrane technology, there is a strong interest in the development of high-performance membranes to meet current and future requirements and challenges [40] . Some materials, including carbon nanotubes, graphene, metal-organic frameworks (MOFs), covalent-organic materials [41][42][43][44][45][46][47][48] , zeolites [49][50] , and double-layered hydroxide, have considerable potential for high-performance membranes due to their high potential [51][52][53][54] . The presence of color in water results from the presence of natural colorants or the entry of industrial wastewater into the water.…”

In this study, the synthesized is nanocomposite (CAU-10-H) all samples were characterized by Scanning electron microscope (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). The (nanofiltration (NF)) membranes were constructed by interfacial polymerization of 1, 3, 5-benzenetricarbonyl trichloride and Piperazine using different loading of (CAU-10-H) (0.250, 0.50% wt.). The removal of color from the water by membranes with Solution filtration showed that the membrane containing 0.50% wt. of the nanocomposite (CAU-10-H) had the best. The removal of color from the water flux rejection of the thin-film nanocomposite (TFN) membrane which the removal of color from the water flux was 25.45 L/m2.hr and Tirmethylcyclohexan-1-one rejection was 99.35% at 6 bar.
