Iranian Researchers Present Model to Determine Dynamic Behavior of Nanostructures

Tehran, Iran | Posted on March 24th, 2015

Results of the research can be used in designing and production of nanosensors and nano-vibrators in electronics, aerospace and military industries.

New forces emerge under the title Casimir forces due to the reduction in the space between structure sheets. The forces significantly affect the instability of nanostructures even during the production without the presence of external driving factors such as voltage.

Dynamic behavior of the structure cannot be understood well in case these forces are ignored in the designing of the devices, and the final results would be unreliable and wrong. These forces should be mathematically modeled and their effects should be studied on the instability of nanostructures in order to achieve more accurate modeling of nanosensors with very sensitive range of activity.

According to the researchers, no research had so far been carried out on the application of functional scaled materials in the field of nanoelectronics. Therefore, this research studies and analyzes non-linear vibration and instable behavior of nanobars in the presence of Casimir intramolecular forces by applying DC voltage.

Evaluations showed that the correct application of functional scaled materials along the thickness of the nanosensor changes the instability area of the nanostructures and it results in their desirable performance at corrosive media at high temperature. In addition, an increase in the response and reaction time to external driving factors, including voltage, can be expected with the new design and correct application of these materials in the production of nanosensors and nano-vibrators.

Results of the research have been published in Composite Structures, vol. 124, issue 1, 2015, pp. 55-64.
