The Department of Nanotechnology at the Faculty of Science  was officially established in Autumn, 2014. The department began its MSc programs by accepting students in Nano-physics and Nano-chemistry. Currently, fundamental nanotechnology laboratories on nano-physics, nano-chemistry and nano-electronic are in full operation. Moreover, the department has nanotechnology research centers in nano-chemistry, nano-physics, nano-electronics and nano-polymers in the City Campus of Urmia University. Some members of the department are currently pursuing their PhD studies. Following their return, the nano-electronic, nano-polymer and nano-biotechnology programs at master’s level are to be launched. Further developments in the department will take place through recruiting PhD students in nano-chemistry as well. The nanotechnology department enjoys the cooperation of full-time faculty members of one associate professor and six assistant professors. We look forward to the day that t...

in  Article ,  News ,  Opinion   How would you feel if you had the choice of having billions of tiny robots injected into your body? A pretty unpleasant thought, am I right? What if I told you that these tiny robots could repair any mutation you may have in your DNA? Sound far-fetched? Well, scientists have been making huge breakthroughs in this! It’s called nanotechnology. These small robots are like tiny computers that are coded to attach to specific cells in your body and carry them from point A to point B. These tiny robots, 1-100nm in size (or 1 and 100 billionth of a meter!),  are like transporters; they pick up the target cell at point A and move it to point B. Point B can be anything from the trash, (cell death) if the cell is not needed anymore, to another part of the body where the cell is needed. They also have the ability to reprogram a cell’s biology. If more of one cell is needed in a particular area it can bring that cell to the specifi...

Another big innovation from the world’s smallest form of technology What type of advanced technology could create winter clothes that capture the body’s heat to help us stay warm, while also potentially cutting down on our home energy bills? The answer is  nanotechnology . According to a recent  Wall Street Journal article , researchers at Stanford University have developed a fabric with silver nanowires that can repurpose the body’s radiant heat. The nanomaterials used to make the fabric capture this heat while maintaining two very important qualities for clothes: breathability and washability. The fabric can generate more warmth by adding a very small amount of electricity – like a sweater with a charger. The researchers estimate that one person could save “about 1,000 kilowatt-hours of electricity a year, or about what an average home uses in a month.” The silver nanowire fabric is another classic example of how something so small can make a big difference by en...

There's an unprecedented multidisciplinary convergence of scientists dedicated to the study of a world so small, we can't see it -- even with a  light microscope . That world is the field of nanotechnology, the realm of  atoms  and nanostructures.  Nanotechnology  i­s so new, no one is really sure what will come of it. Even so, predictions range from the ability to reproduce things like diamonds and food to the world being devoured by self-replicating nanorobots. In order to understand the unusual world of nanotechnology, we need to get an idea of the units of measure involved. A centimeter is one-hundredth of a meter, a millimeter is one-thousandth of a meter, and a micrometer is one-millionth of a meter, but all of these are still huge compared to the nanoscale. A  nanometer   (nm)  is one-billionth of a meter, smaller than the wavelength of visible light and a hundred-thousandth the width of a human hair [source:  Berkeley Lab ]. ...
