Toxicological and Life-Cycle Perspectives on Waste-Derived Nanoparticles

Journal of Materials Science and Chemical Engineering 2024年第8期12卷 43-68页

作者： Irshad Ahmad Md Fahimul Hassan Weqar Ahmad Siddiqui Department of Applied Science & Humanities Faculty of Engineering & Technology Jamia Millia Islamia University New Delhi India Department of Chemistry C.M. Science College Lalit Narayan Mithila University Darbhanga India

Many nanoparticles have been created over the last few decades using a variety of techniques and used to develop environmental technology, including water treatment, the detection of persistent contaminants, and soil and water remediation. The studies of alternative inputs for nanoparticle production as well as the use of green synthesis techniques are driven by the field of materials science and engineering’s growing interest in increasing the sustainability of the processes involved in their production. In this paper, we begin by providing an overview of the fundamental principles of producing nanoparticles from different sources, such as plastic, electronic, metal, and industrial waste. We elaborate on key facts of waste identification as a workable input for the treatment and recovery of metal and carbon-based nanoparticles. We next go over several controlling factors that play a role in creating nanoparticles, pointing out probable conclusions as we go. Then, we show some instances of waste-derived nanoparticles used in a proof-of-concept experiment of technology for applications in water quality and safety. Before scaling up production and implementing waste-derived nanoparticles, there are several present problems from the toxicological and life-cycle perspectives that must be taken into account.

First-principles calculations of structural, electronic, and thermodynamic properties of ZnO_(1-x)S_x alloys

引用

Chinese Physics B 2014年第10期23卷 394-400页

作者： Muhammad Zafar Shabbir Ahmed M.Shakil M.A.Choudhary Simulation Laboratory Department of Physics The Islamia University of Bahawalpur

In this study the pseudo-potential method is used to investigate the structural, electronic, and thermodynamic proper- ties of ZnOl_xSx semiconductor materials. The results show that the electronic properties are found to be improved when calculated by using LDA ~ U functional as compared with local density approximation （LDA）. At various concentrations the ground-state properties are determined for bulk materials ZnO, ZnS, and their tertiary alloys in cubic zinc-blende phase. From the results, a minor difference is observed between the lattice parameters from Vegard＇s law and other calculated results, which may be due to the large mismatch between lattice parameters of binary compounds ZnO and ZnS. A small deviation in the bulk modulus from linear concentration dependence is also observed for each of these alloys. The ther- modynamic properties, including the phonon contribution to Helmholtz free energy △F, phonon contribution to internal energy △E, and specific iheat at constant-volume Cv, are calculated within quasi-harmonic approximation based on the calculated phonon dispersion relations.
