In the present work, rapid identification of elements and their relative chemical composition in various Peganum harmala seed samples were investigated using a calibration-free laser-induced breakdown spectroscopy technique (CF-LIBS). A pulsed Nd:YAG laser-source with 5 ns pulse-duration, 10 Hz pulse repetition rates providing 400 200 mJ energy at 1064 532 nm wavelength, respectively, was focus...

Iron nanomaterials are widely present in the environment and their concentrations increasing day by day. In many applications, iron included, but minimum maximum that not harmful to plants yet known. Effect of F3O4(NPs) on Peganum harmala for purpose showing anatomical responses as effective biomarkers concentration ecosystem. Electron microscopy determine effect different doses ranging from (0...
