“…EDITED BY compounds such as nanoparticles, zeolite, activated carbon and nanofibers were used for CH 4 gas adsorption (Conte et al, 2020;Karimi et al, 2021). Although these compounds have capabilities in the field of CH 4 gas adsorption, their efficiency is not ideal for adsorption applications (Zuo et al, 2022).…”

In this study, novel nanostructures based on Ni-MOF/polysulfone nanofibers were fabricated by microwave-assisted electrospinning method. The final Ni-MOF/polysulfone fibrous nanostructure were immobilized on SiO2 substrates with high physicho-chemical properties. These nanostructures with an average diameter of 20 nm and a specific surface area of 1690 m2/g were used as novel adsorption for CH4 gas adsorption. It seems that the integration of novel Ni-MOF compounds into the fibrous network has differentiated these materials from previous samples. Since the experimental parameters significantly affect the specific surface area, the parameters including voltage, concentration, and distance between the collector and source are designed by the fractional factorial method. The results were optimized by contour plots, ANOVA and surface plots, theoretically. The results show that the sample has an adsorption rate of about 5.14 mmoL/g. The improved CH4 gas adsorption performance is attributed to the large specific surface area and porous nature of the Ni-MOF/Ps nanostructure which is more convenient and accessible for CH4 gas adsorption.

“…Eventually, they can capture up to 90% of the CO 2 from the ue gas of fossil-fuel power plants [10]. In addition, the adsorption of CO 2 on materials like zeolites, activated carbon, amine-functionalized adsorbents, or metal-organic frameworks can also be utilized for CO 2 capture [8, [11][12][13]. These processes are particularly interesting when they involve materials having good gas sensitivity in atmospheric conditions, which is also seen for several conducting polymers.…”

The emission of carbon dioxide (CO2) is not only the primary cause of global warming but also results in severe environmental issues like an increase in Earth's average temperature. Herein, polymeric Schiff bases, OPVA-ED and OPVA-HMD, are synthesized via the condensation of partially oxidized polyviny1 alcohol (OPVA) with 1,2-ethylene diamine (ED) and 1,6-hexamethylene diamine (HMD), respectively, and their potential toward CO2 adsorption is investigated. Fourier transform infrared (FTIR), 1H nuclear magnetic resonance (NMR), and X-ray diffraction (XRD) are employed for the structural elucidation of these Schiff bases, and their physical properties are determined using thermogravimetric analysis (TGA), and gas adsorption experiments. The capture/release of CO2, using these Schiff bases as adsorbent, is assessed at 25°C. The results suggest that OPVA-ED is a more efficient adsorbent for CO2 as compared to OPVA-HMD, as the capacity of CO2 adsorption reaches up to 0.22 mmol/g and 0.18 mmol/g at 15 bars for OPVA-ED and OPVA-HMD, respectively.

“…Kevlar plate production in Indonesia is also still considered too expensive because it requires expensive raw materials and infrastructure. Commercial kevlar is synthesized in a solution from the monomer 1,4-phenylenediamine (paraphenylenediamine) and terephthaloyl chloride in a condensation reaction which produces hydrochloric acid as a side product [5]. Then, this reaction also produces a polymer in liquid crystal form.…”

The dependence on the imported bullet-proof vest as one of the main equipments of the National Defense System needs attention. This condition treats the independence of domestic defense security. In contrast, the potential of natural materials for bullet-proof vest plates are abundant in Indonesia. Nata de Coco is one of the natural raw materials for producing bullet-proof vest plates that has the potential to be developed. This preliminary research proved that increasing the bond strength of cellulose in Nata de Coco was performed by adding the appropriate crosslinkers. The addition of carboxymethylcellulose (CMC) 2% crosslinker to form Nata de Coco kevlar-like plates (Navlar) was evidenced to increase threefold tensile strength (99.15 MPa) from its original Nata de Coco (31.92 MPa). The development of Navlar is a very strategic sector for producing high-quality bullet-proof vest plates equivalent to kevlar strength. Navlar is more prospective than Kevlar due to its abundant source, cheap, lightweight, and ease to manufacture. Developing Navlar could replace the dependence on imported Kevlar and support the domestic defense industry.
