Abstract: Mormodica charantia is a plant of the Cucurbitaceae family known as bitter melon, karela, and pare. It grows in tropical areas of the Amazon, Asia, South America India, East Africa and Nigeria. It’s used traditionally as both food and medicine. Thisresearch showed the phytochemical and antimicrobial effects on the green synthesis of silver nanoparticles from Mormodica charantia. The phytochemical screening of the leaf extracts and the antimicrobial effect of Mormodica charantiawere studied. The aqueous extract of the plants was prepared from the leaves of the plant for the green synthesis of the silver nanoparticles. The phytochemical screening of the leaf extracts and the antimicrobial analysis were also carried out. The synthesized silver nanoparticles were characterized using Fourier Transmission Infrared Spectroscopy (FTIR). This study showed that Mormodica charantia inhibits the growth of E. coli but, has high inhibitory effect on the growth of fungi, Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus, Fusarium solani and Candida albican tested. This suggests that these plants can be used for the treatment of fungi related diseases. The phytochemical screening results of the plants studied showed that they are good sources of alkaloids, flavonoids, saponins, terpenoids etc. which can be used in pharmacology. The FTIR results of the silver nanoparticles showed only a noticeable difference in the spectra of (Mormodica charantia) and (Mormodica charantia-AgNPs) in that the band 1327 cm-1 present in (Mormodica charantia) disappeared in (Mormodica charantia-AgNPs) and the band at 1593 cm-1 was observed in (Mormodica charantia-AgNPs) spectra. The band at 1593cm-1 in the as-synthesized (Mormodica charantia-AgNPs) suggested possible coordination of the (Mormodica charantia-AgNPs) with carboxylate ions formed during the reduction. FTIR spectra analysis confirmed conversion of Ag+ ions to AgNPs (Ag+ to Ag0) to reduction by capping material of plant extract.Abstract: Mormodica charantia is a plant of the Cucurbitaceae family known as bitter melon, karela, and pare.

Abstract: A high safety electric spinning device was tested to produce nanofibers from different polymers, and the spinning was tested on the human hand directly without feeling any short circuit. The locally designed device consists of a voltage lifter, an injection pump and a rotating cylindrical collector. The voltage booster is based on converting AC current from 220V to 50KV. The injection pump has four variables: the first variable to control the speed of pumping the solution from the injector, the second variable to control the movement of the injector on a metal rail back and forth, and the third variable to control the speed of rotation of the cylinder accumulator through time, The fourth variable is to push the injector in reverse to refill it again, and the distance of the collector from the injector can be controlled, and it can also be replaced with a flat metal plate. The viscosity of polyacrylonitrile solutions with different concentrations was studied and then spun with the designed device and the radii were measured via a scanning electron microscope, then the effect of the voltage change on the change of the average diameter of the fibers was studied when the concentration was fixed and it was found that with the increase in the applied potential difference the average diameter decreases The resulting nanofibers.Abstract: A high safety electric spinning device was tested to produce nanofibers from different polymers, and the spinning was tested on the human hand directly without feeling any short circuit.
