Dr. Elnaz Hashemi is a Postdoctoral Fellow at the Department of Mechanical and Aerospace Engineering and a member of the Energy and Particle Technology Laboratory (EPTL) at Carleton University. She received her B.Sc. in Materials Engineering from the University of Tabriz and earned both her M.Sc. and Ph.D. degrees in Nanotechnology–Nanomaterials from Tarbiat Modares University (TMU), Iran. Her research mainly focuses on the synthesis, design, and optical characterization of nanostructured materials for applications in photocatalytic hydrogen generation, wastewater treatment, and environmental sensing. During her undergraduate studies, she participated in a research project on the electrophoretic deposition of cobalt ferrite nanoparticles and iron particles on carbon fibers as a microwave-absorbing composite. Throughout postgraduate studies, she developed a wide range of particle, wire, and flake-like nanostructures and established a series of metal oxide-based and graphitic carbon nitride nanostructures, as well as multi-junction semiconductor heterostructures with enhanced light absorption and charge separation efficiency. Her research also explored the effects of synthesis parameters such as current intensity, electrode material, and reaction environment on the structure, composition, and optical behavior of nanomaterials synthesized via electrical arc discharge in liquid media. She designed and built a custom electrical arc discharge system for synthesizing metal oxide and plasmonic nanomaterials and conducted real-time arc discharge characterization by monitoring current–voltage behavior and performing plasma diagnostics using optical emission spectroscopy to analyze reactive species in various liquid media. Additionally, she investigated the effects of platinum and phosphorus doping in multi-heterojunction photocatalytic systems such as Bi₂O₃/Bi₂O₂CO₃–Pt/PCN to enhance photocatalytic performance under visible light.
She possesses extensive experience in the synthesis and characterization of semiconductor, metallic, and plasmonic nanostructures. Her expertise includes techniques such as X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), Raman, FTIR, UV-Vis, and photoluminescence (PL).
Elnaz joined Carleton University as a Visiting Researcher, where she was working on the synthesis of nanomaterials by the Flame Spray Pyrolysis method and their deposition on Tilted Fiber Bragg Grating optical fibers for sensing applications.
