A method for measuring the contact area in instrumented indentation testing by tip scanning probe microscopy imaging [PDF]

open access: yes, 2014
The determination of the contact area is a key step to derive mechanical properties such as hardness or an elastic modulus by instrumented indentation testing. Two families of procedures are dedicated to extracting this area: on the one hand, post mortem

Low Temperature-Mediated Enhancement of Photoacoustic Imaging Depth [PDF]

open access: yesScientific Reports, 2018
AbstractWe study the temperature dependence of the underlying mechanisms related to the signal strength and imaging depth in photoacoustic imaging. The presented theoretical and experimental results indicate that imaging depth can be improved by lowering the temperature of the intermediate medium that the laser passes through to reach the imaging ...
