“…They consist of a porous membrane that acts as a physical barrier between the gas and liquid phases, allowing selective transfer of gases while preventing the mixing of the two phases. This unique structure enables several advantages regarding mass transfer rates and process efficiency 6 . MCs offer a substantial interfacial area, promoting the efficient mass transfer and enabling the effective removal of specific impurities like CO 2 and H 2 S from gas streams.…”

The release of excessive carbon dioxide (CO2) into the atmosphere poses potential threats to the well-being of various species on Earth as it contributes to global working. Therefore, it is necessary to implement appropriate actions to moderate CO2 emissions. A hollow fiber membrane contactor is an emerging technology that combines the advantages of separation processes and chemical absorptions. This study investigates the efficacy of wet and falling film membrane contactors (FFMC) in enhancing CO2 absorption in a monoethanolamine (MEA) aqueous solution. By analyzing factors such as membrane surface area, gas flow rate, liquid inlet flow rates, gas–liquid contact time, and solvent loading, we examine the CO2 absorption process in both contactors. Our results reveal a clear advantage of FFMC, achieving an impressive 85% CO2 removal efficiency compared to 60% with wet membranes. We employ COMSOL Multiphysics 6.1 simulation software and finite element analysis to validate our findings, demonstrating a close agreement between predicted and experimental values, with an average relative error of approximately 4.3%. These findings highlight the significant promise of FFMC for applications in CO2 capture.

“…Photosensitizers of the third generation typically apply to improvements such as biological conjugates (e.g. antibody conjugate, liposome conjugate) and built-in capabilities for photo quenching or bleaching (Kianfar, 2022;Salahdin et al, 2022;Kianfar et al, 2022b;Isola et al, 2022;Fattah et al, 2023).The target-specific PDT uses photosensitizers that combine the sensitivity of an over-expressed cell marker with the phototoxic properties of the conjugated PDT photosensitizer with the antibody-or antisense-conjugated photosensitizers (Kadhim et al, 2023;Al-Awsi et al, 2023). A quick analysis of the advantages and deficiencies of each is worthwhile (Table 2).…”

Most of the treatment strategies for tumors and other disorders is photodynamic therapy (PDT). For several years, increasing the efficiency of nanostructured treatment devices, including light therapy, has been considered in different treatment methods. Light Dynamics The use of nanomaterial in this method's production and progress. The use of nanoparticles as carriers is a promising accomplishment, since all the criteria for an ideal photodynamic therapy agent can be given with these nanomaterials. The kinds of nanoparticles that have recently been used in photodynamic therapy are mentioned in this article. Latest advancements are being explored in the use of inorganic nanoparticles and biodegradable polymer-based nanomaterial as carriers of photosynthetic agents. Photosynthetic nanoparticles, self-propagating nanoparticles, and conversion nanoparticles are among the successful photodynamic therapy nanoparticles addressed in this report.

“…The device that performs this process is generally called a chemical sensor. This device collects information about the chemical composition of its operating environment and transmits it to the processor as an optical or electrical signal (Mahmood et al, 2022;Smaisim et al, 2023;Fattah et al, 2023). Figure 13 shows the mechanism of action of a chemical sensor.…”

Nanosensors work on the “Nano” scale. “Nano” is a unit of measurement around 10− 9 m. A nanosensor is a device capable of carrying data and information about the behavior and characteristics of particles at the nanoscale level to the macroscopic level. Nanosensors can be used to detect chemical or mechanical information such as the presence of chemical species and nanoparticles or monitor physical parameters such as temperature on the nanoscale. Nanosensors are emerging as promising tools for applications in agriculture. They offer an enormous upgrade in selectivity, speed, and sensitivity compared to traditional chemical and biological methods. Nanosensors can be used for the determination of microbe and contaminants. With the advancement of science in the world and the advent of electronic equipment and the great changes that have taken place in recent decades, the need to build more accurate, smaller and more capable sensors was felt. Today, high-sensitivity sensors are used that are sensitive to small amounts of gas, heat, or radiation. Increasing the sensitivity, efficiency and accuracy of these sensors requires the discovery of new materials and tools. Nano sensors are nanometer-sized sensors that, due to their small size and nanometer size, have such high accuracy and responsiveness that they react even to the presence of several atoms of a gas. Nano sensors are inherently smaller and more sensitive than other sensors.
