    Identification of Elements Exist in Area Around Khartoum Petroleum Refinery Using Spectroscopic Method

    By Khalid Mohammed Haroun, Zeinab M. Mohammed, Mona Ali, Abdalskhi S. M. H

    Abstract: Laser-induced breakdown spectroscopy (LIBS) is a method of atomic emission spectroscopy (AES) that uses a laser-generated plasma as the hot vaporization, atomization, and excitation source. Plasma is often called the fourth state of matter. The various states of matter occur as a substance is heated to temperatures corresponding to thermal energies above the binding energies for particular state of matter. Structured systems placed in a sufficiently hot environment. LIBS technique …

    Optical Properties of Barium Borate (BaB2O4)Compound for Current Optoelectronic Applications

    By Ibtehag Ali Sanosy, Khalid Mohammed Haroun, Abdalsakhi Suliman Mohammed Hamed, Adam Mohammed Adam Bakheet

    Abstract: In this work,Barium borate was prepared by sol-gel synthesisdepending on different molar (0.1, 0.2, 0.3 0.4 and 0.5) molar. Barium borate is an inorganic compound, and it was useda borate of barium with a chemical formula BaB2O4 or Ba(BO2)2 It is available as hydrate or dehydrated form, as white powder or colorless crystals. The optical characteristics of the prepared samples have been investigated by UV/Vis spectrophotometer in the wavelength range …
