Synthesis and Characterization of CuO Microflowers/Ppy Nanowires NCs as Anode Materials for Lithium-ion Battery
, M.Sc. Thesis Sharif University of Technology ; Sadrnezhad, Khatiboleslam (Supervisor)
Abstract
Novel Copper Oxide microflowers /Polypyrroles nanowire nanocomposites with various wight ratio have been synthesized.The synthesized CuO/Ppy NCs and Cuo microflowers are characterized by XRD, FT-IR, TGA, FESEM and EDX line analysis/elemntal mapping. The formation mechanism of CuO microflower and Ppy nanowires are also well explained.All syntesized samples have been used as as anode material for li-ion batteries in order to measure their electochemical lithium-ion storage properties. It is demonstrated that presence of Ppy nanowire with different weight ratio plays important role in lithium-storage properties of the hybrid CuO/Ppy NCs. With increase in the mass ratio of Ppy nanowire cyclic...
Relativistic Magnetohydrodynamics of a Spinful and Vortical Fluid: Entropy Current Analysis and Transport Coefficients
, M.Sc. Thesis Sharif University of Technology ; Sadooghi, Neda (Supervisor) ; Kiamari, Motahareh (Co-Supervisor)
Abstract
Fluid Mechanics can be considered as an effective method for studying many-body effects in classical and quantum systems. In recent years, relativistic hydrodynamics has found different applications in different branches of physics. One of these applications is the quantitative description of the experimental behavior of relativistic heavy-ion collisions. More specifically, studying fluid mechanics in the presence of magnetic fields (magnetohydrodynamics) and vorticity is of great importance in heavy-ion collision experiments. In this framework, on the one hand, the interaction between spin and magnetic field, and on the other hand, the interaction between spin and angular momentum of the...
