The whole membrane fabrication just cost 3 h and took place at room temperature, which was much more efficient than other membranes with similar performance.
It is believed that the present cost of membranes is much higher than the real manufacturing cost.
The results showed a waste cost of 1.4 £ m−2 of membrane, significantly lower than PI based membranes.
This will aid in cutting down cost since frequent cleaning of membranes shortens the membrane life span.
However, the operation cost of membranes cannot be decreased unless the amount of fouling, the “Achilles heel” of membranes, and energy consumed are cut.
The advantages of the use of membranes are simplicity, innocuousness, low-cost and easy incorporation within automatic systems.
Flexible, large surface-area VACNT membranes may provide a cost-efficient solution to various separation processes such as water purification and gas separation.
The production is optimized to be a simple and highly repeatable process that does not require sophisticated equipment and is suitable for scaled production of low-cost water purification membranes.
The cost of the membranes can be lowered by using a GB approach compared with GO-mixed matrix membranes because of the reusability of GO in a coagulation bath.
Thus, these all-polymeric membranes are suitable for the commercialization of gas separation owing to their simple fabrication method and low cost.

The forward reaction coefficient of the surface conjugation parameter in ISFET biosensors is a critical factor that influences the device's sensitivity and specificity towards target analytes, including viral molecules and various ions. The design of an immunosensor for viral molecules, as proposed by Gasparyan et al., utilizes the modulation of the surface potential at the semiconductor-dielectric interface, which is directly influenced by the interaction and immobilization of viral molecules on the ISFET's surface. This interaction underscores the importance of the surface conjugation parameter in determining the ISFET's response to specific analytes. The advancements in ISFET technology, highlighted by Surmalyan, emphasize the device's high sensitivity and fast response time, which are partly attributed to the effective surface conjugation of analytes, enabling rapid detection of pH changes or ion concentrations. Similarly, the development of an ISFET device selective to anionic detergents by Campanella et al. demonstrates the role of surface conjugation in extending the linearity range of detection for specific surfactants. Gordon et al.'s work on parameter extraction models for ISFET devices in polyelectrolyte media further elucidates the importance of understanding the surface conjugation dynamics to improve the device's field use for biological and chemical sensing.

Ye et al.'s model development using COMSOL Multiphysics emphasizes the sensitivity of ISFETs to pH changes, which can be optimized by understanding the surface conjugation parameters. Dhar et al.'s TCAD simulations of ISFETs reveal a correlation between device dimensions and sensitivity, suggesting that the forward reaction coefficient of surface conjugation can be influenced by the physical structure of the ISFET. Poghossian and Schöning's multi-parameter sensor system, which uses a Ta2O5-gate ISFET, demonstrates the versatility of ISFETs in detecting various parameters through effective surface conjugation strategies. Lastly, Alegret et al.'s construction method for a PVC-matrix membrane ISFET-based urea sensor illustrates the practical application of understanding the forward reaction coefficient in developing sensitive and stable biosensors. In summary, the forward reaction coefficient of the surface conjugation parameter plays a pivotal role in the functionality and performance of ISFET biosensors, influencing their sensitivity, specificity, and overall effectiveness in detecting a wide range of analytes.

What are the problems in the effective removal ofloxacin from wastewater?
5 answers
The effective removal of ofloxacin from wastewater faces several challenges. One major issue is the high efficiency of fluoroquinolones like ofloxacin, leading to their widespread use and subsequent release into effluents. Conventional wastewater treatment methods are relatively ineffective in removing antibiotics, including ofloxacin, from effluents. Effluents from industries and hospitals are significant sources of ofloxacin release into the environment.

What phenomenon caused the wettability to change from oil-loving to water-loving by hydrogel on pva base?
5 answers
The phenomenon that caused the wettability to change from oil-loving to water-loving by a hydrogel on a PVA base is the alteration of wettability induced by the presence of surfactants in the drilling fluid. Specifically, the addition of nonionic surfactants like polyethylene glycol (PEG) in the water-based drilling fluids led to a change in the wettability of the reservoir rock from oleophilic to hydrophilic. This alteration in wettability was crucial in reducing formation damage and increasing oil production, as observed in carbonate reservoirs. The surfactants facilitated this change by interacting with the rock surface, causing it to shift from an oil-loving state to a water-loving state, ultimately enhancing reservoir productivity.
