Pakistan Science Club has collaborated with the KSS to organize the National Science and Innovation Fair 2019. If you are of age 12-20 and want to create a positive impact on the society using your innovative ideas and technology, here is a chance to present your work. We are bribing you an exciting challenge to participate and showcase your novel ideas on projects in National Science and Innovation Fair 2019.
Semiconductor nanowires (NWs) are attracting wide interest due to their unique physical properties and potential for application in nanodevices. NWs can be obtained by a number of growth methods, and their highly anisotropic growth originates by the presence of a metal particle, the catalyst, that determines the position and the diameter of the nanostructure. The most widely used catalyst is gold. The growth mechanism of catalyst assisted nanowires involves the incorporation of material both impinging on the catalyst particle and diffusing from the free substrate surface to the sidewalls of the wire. The interplay of these two phenomena is critical especially for the growth of alloy semiconductor compound NWs and one dimensional (1-D) heterostructure.
Nanotechnology research in Pakistan dates back to late 1990’s and at the moment it is one of the hottest research topic in the country. A number of research groups in private and government sector holds promise to bring this futuristic but practical technology to Pakistan. Carbon based Nanotechnology research was initiated in PINSTECH in 1998 by accidental observation of carbon clusters in locally developed heavy ion accelerator. The research was accelerated in 2003 with the funding of Ministry of Science and Technology to make Pakistan’s first research laboratory dedicated for carbon based nano-science and technology. In this introductory talk I will give a glimpse of indigenous research we are doing in PINSTECH that includes both experimental and computational areas. The aim of this talk is to prove that Pakistan is not so backward in this high-tech area and we would like to invite and promote youngsters to step into this new but developing area.
This talk will be focused on some of the scientific themes and applications in which electron energies reached for device or process operation are above that of the surrounding lattice or environment. Within the scope of the topic I will attempt to describe the vision of the global nanoscience community which is to ‘exploit science in the nano-scale to inspire intelligent devices that can shape the future’. Freeman Dyson once said; “Technology is a gift of God. After the gift of life it is perhaps the greatest of God’s gifts. It is the mother of civilizations, of arts and of sciences.” With this in mind, I will also talk about what we can do to help take our ideas in the exploitation of knowledge to build good technologies for the future.
