Research Highlights
Let me guide you in the world of Nanotechnology!
"A scientist in his laboratory is not a mere technician: he is also a child confronting natural phenomena that impress him as though they were fairy tales."

Nanorods - One Dimensional nanomaterial
This image was taken on a Scanning Electron Microscope. In general, 1-D nanostructures are one of the most important materials due to their fascinating physical properties. They have a wide range of applications especially in solar energy conversion, thermoelectric devices and energy storage technology.
Cross like-shaped Zinc Titanates
Zinc Titanates (or ZnTiO3) are semi-conductors that can be synthesized in various morphologies, following different synthetic routes. Cross- like shape was achieved by a room temperature synthetic method. The morphologies can be captured by Scanning Electron Microscope.
Electron diffraction pattern of
ZnO nanoparticles
This picture was taken on a Transmission Electron Microscope with an electron diffraction technique. Interpretation and analysis of diffraction pattern is a method to identify the phases of the semiconductors. Using the radius of each ring, we can specify the distance between the planes or interplanar spacing. The above ring and spots pattern reveal the polycrystalline nature of the sample.
Magnetic nanoparticles
Magnetic nanoparticles can be used in a broad spectrum of magnetic recording media and bio-medical applications, for example, magnetic resonance contrast media and therapeutic agents in cancer treatment. Also, they can be found in data storage applications where they need to have a stable, switchable magnetic state to represent bits of information that are not affected by temperature fluctuations.
Photocatalytic Hydrogen Production
Hydrgoen is considered to be a promising alternative to fossil fuels due to its high energy content and environmental impact. Among various methods, hydrogen produ-ction via photocatalytic water-splitting is of growing interest as a low-cost and environmentally friendly process. As it is shown in the picture, it uses renewable sources (warer and solar light) and a photoactive catalyst that can split water to hydrogen and oxygen.
Degradation of organic water pollutants
The removal of hazardous materials such as toxic dyes and organic residuals from waste water is of growing interest over the recent years. As it is shown in the diagram, organic pollutants can be degraded, after 150 minutes (orange line), by using ZnO semiconductors under visible light illumination.
