Nano- and micro-mechanics

We seek to understand the governing mechanisms for deformation and mechanical properties in small-scale materials or materials that are microstructurally complex. With advanced nano- or micro-mechanical testing capabilities, we can observe defect mechanisms at the atomic to mesoscale level in real-time while accurately measuring related mechanical properties.

(In situ) electron microscopy

Recent advancements in aberration-corrected S/TEM and in-situ electron microscopy techniques have revolutionized the way we examine the microstructure and evolution of materials, offering high-resolution and precise quantitative insights. Within our group, we are not only utilizing these cutting-edge techniques but also actively pushing the boundaries of the testing methods. Our goal is to offer unparalleled insights into the intricate behavior of materials, delving into the atomic level to unravel their mysteries.
