What is the News?

An Indian researcher has developed a new method to test nanomechanical properties of materials at very minute scales with high precision and accuracy.

This new method significantly improves the precision and accuracy of Nanoindentation Technique.

What is Nanoindentation Technique?

Nanoindentation is a materials testing technique used to measure mechanical properties such as hardness, elastic modulus and other material responses at very small scales, often on the order of nanometers. 

The technique involves applying a controlled and localized force to a material’s surface using a sharp indenter, typically a diamond tip, and then measuring the resulting depth of penetration.

The nanoindentation technique is particularly valuable for studying materials at the micro- and nanoscale, where traditional macro-scale mechanical testing methods are not suitable or accurate.

Applications: Nanoindentation is used in a wide range of applications, including characterizing thin films, coatings, biomaterials, ceramics, polymers, metals and composites. 

– It is also employed in research related to microelectronics, material development, quality control and failure analysis.
