Latest work with IntechOpen by Ishaq Ahmad

A wide variety of ion beam techniques are being used in several versatile applications ranging from environmental science, nuclear physics, microdevice fabrication to materials science. In addition, new applications of ion beam techniques across a broad range of disciplines and fields are also being discovered frequently. In this book, the latest research and development on progress in ion beam techniques has been compiled and an overview of ion beam irradiation-induced applications in nanomaterial-focused ion beam applications, ion beam analysis techniques, as well as ion implantation application in cells is provided. Moreover, simulations of ion beam-induced damage to structural materials of nuclear fusion reactors are also presented in this book.

A particle-induced X-ray emission (PIXE) study has been carried out to find out whether available local and imported cigarette brands in Pakistan have elevated concentration of metals or not. The results are compared within the brands examined in this study and with the results of related studies in literature. A sum of 19 different cigarette brands was purchased randomly from different Pakistani markets which included local and imported brands. The concentration of elements like Cd, Pb, Zn, Fe, Mn, Ni, Cu, and Co was investigated. Results showed that different cigarette brands have different metal contents. The mean concentration of the heavy metals is Cd—4.92 μg/g, Co—0.12 μg/g, Cu—0.97 μg/g, Ni—0.13 μg/g, Pb—1.02 μg/g, and Zn—12.91 μg/g per dry weight. Compared with the reported results of other international studies, Pakistani cigarettes are observed to have lower heavy metal contents except for cadmium which was higher. This study will provide adequate data for all concerned departments. This study will also create awareness among people about the toxicity of metals present in tobacco of cigarettes.

Ion Implantation in Metal Nanowires

By Shehla Honey, Asim Jamil, Samson O. Aisida, Ishaq Ahmad, Tingkai Zhao and Maaza Malek

Ion implantation-induced materials modifications are the recent scope of research. A detailed recent experimental research on the effect of low- and high-energy ions implantation-induced morphological and structural changes in metal nanowires (MNWs) is being presented in this chapter. These morphological and structural changes in metal nanowires are discussed on the basis of collision cascade effects and ion beam-induced heats produced along the ion tracks. Various technical aspects of implantation of low energy ions in MNWs, their advantages, and drawbacks are also discussed in this chapter. Furthermore, detailed overview of implantations of ions in MNWs is also discussed.
