Ahmed Al-Tabbakh is a professor of applied physics at the Department of Physics, Al-Nahrain University, Baghdad, Iraq. He earned his MSc in physics at Al Nahrain University, Baghdad (in 2001), and his PhD degree in applied physics from Pune University, India (in 2009). Then he worked as a postdoctoral research fellow at the Centre for Nanomaterials Research, Universiti Teknologi MARA, Malaysia (2011-2013). He authored more than 30 scientific papers in peer-reviewed journals. Dr. Ahmed is interested in developing nanomaterials and nanostructures for energy storage applications and for cold cathodes. He is also interested in understanding the field emission phenomenon in metals and semiconductors, and more recently in cold cathodes arrays. His skills include synthesis, characterization and test of nanomaterials for Li ion batteries, working with X-ray diffraction measuremnts and XRD qlitative and quantitative analysis software, Operating SIMION7-3D Design Package for Electron Optics and FORTRAN Language programming. Dr. Al-Tabbakh is an active reviewer of a number of international scientific journals.

Ahmed A. Al-Amiery earned his Bachelor's degree in general chemistry (1998) at Al-Mustansiriya University, Iraq. Then he obtained his Master's degree in organic chemistry (2001) from the University of Baghdad, and his PhD (2007) in organic chemistry from Al-Mustansiriya University. At present, he teaches basic organic chemistry and industrial chemistry at the University of Technology. His scientific interests focus mainly on the synthesis of novel applicable molecules. Plants play an important role in his research, as they are the source of chemical compounds that Al-Amiery extracts and analyzes, in order to identify active principles of pharmacological interest. He has authored more than 150 scientific papers and sits in several commissions at the University of Technology. He is also Editor in Chief for 2 journals and editor in many international journals. Al-Almieri is the owner of 15 international patents on substances that inhibit corrosion, and has published 14 books.
