Dr. Shaoting Lin of Michigan State University presents his research on hydrogel adhesions and coatings. Dr. Lin's work is at the intersection of polymer science, solid mechanics, and advanced manufacturing, and he used a KLA nanoindentation system to study the effects of static and cycling loading as they contribute to hydrogel failure.

Hydrogen embrittlement has been of ongoing interest to materials science community and industries over the past several decades. In-situ electrochemical nanoindentation became a versatile tool for probing the impact of electrochemical charging on different materials and technical relevant alloy systems. Besides measuring the classical mechanical properties, such as hardness and Young’s modulus...

Nanoindentation is typically performed at slow strain rates < ~0.1/s, which precludes it from ballistic applications. Recent years have seen the development of nano-impact testing, which produces much higher deformation rates. However, data from such experiments are challenging to interpret, because the high strain rates are not sustained throughout the experiment and the classical definitio...

Although optical coatings are designed for the control of light (anti-reflective, reflective, splitting, filtering, etc.) it is their mechanical properties which govern longevity. Scratches at any scale lead to excessive absorption of laser energy causing localized thermal stress and ultimate failure. This session is a live demonstration of dynamic nanoindentation with the KLA iMicro nanoindent...
