in the realm of design optimization. This study employs the finite element method (FEM) through COMSOLMultiphysics software (Version 4.0) to simulate direct current discharge plasma within argon gas under vacuum (2×10−1 mbar). The primary objective is to compare the plasma distribution characteristics resulting from two distinct cathode configurations: a planar cathode, and a concave cathode. […]
One of the biological techniques which can be used to create nanoparticles is the green synthesis method. The silver nitrate and the extract of the pepper leaf are employed to create silver nanoparticles. The scanning electron microscope (FE-SEM) revealed that there are findings of silver nanoparticles with diameters ranging from (23 nm) to (73 nm). […]
