Islamabad—Quaid-i-AzamUniversity (QAU) Physics faculty members Dr. ArifMumtaz and Dr. S.K. Hasanain, have achieved a rare recognition for their paper “Synthesis and magnetic properties of cobalt ferrite (CoFe2O4) nanoparticles prepared by wet chemical route” published in The Journal of Magnetism and Magnetic Materials, which is in the top 1% of internationally cited papers according to the Thomson-Reuters ISI Impact Factor Index. The paper has 297 citations on that index, which makes it the most cited paper from any physics department in Pakistan.It also has 414 Google Scholar citations. Nanoparticles are ultra-small particles with a minimum of one dimension smaller than 100 nanometers (1 nanometer = one billionth of a meter). These super tiny particles act as the building blocks of matter and form the link between bulk materials on the one hand and atoms and molecules and related structures on the other. Investigation into nanoparticles has a wide variety of uses, which include medicine, optics, and electronics. At Quaid-i-Azam University, Islamabad, the Department of Physics is engaged in research into these strange and potentially highly useful particles.
