A recent press released from the Moscow Institute of Physics and Technology (MIPT) has said that a group of scientists have managed to develop new technique to measure the length and diameter of nanotubes and nanofibres suspended in water by using ultrasonic waves. The announcement also noted that the discovery can be used to measure any kind of nanoobjects.
Talking about the discovery, departmental head of Electronics, Photonics, and Molecular Physics at MIPT, Viktor Ivanov said, “The established technique can be used to define diameter and length of lengthy nanoobjects of an arbitrary composition. In this work, we have chosen carbon nanomaterials as objects because of their high applicability.”
In case you didn’t know, Carbon nanotubes and nanofibers represent both stable and flexible materials that can be used to accomplish different goals. For example, nanotubes can be added to the anode of lithium ion battery that would increase the capacity by significant margin. However, in order to successfully accomplish goals similar goals, it’s important to know the precise size and the new discovery could open up possibility for greater results.
Viktor Ivanov said, “We developed a method of measuring sizes of cylindrical nanoobjects, in which the length is greater than the diameter. However, we believe, that a similar technique might be applied to the opposite case to study nanoobjects having a diameter greater than the length, i.e. for nanodiscs including for instance graphene.”
