In this study, published in Advanced Science, the team successfully developed unique and unexplored two-dimensional (2D) nanomaterials V-MXene for the very first time coupled with precious metal ruthenium (Ru) through the ALD process. This breakthrough holds immense promise for various applications, both contact and non-contact mode of real-time temperature sensing at the human-machine interface.

The integration of Ru-engineered V-MXene through ALD has demonstrated a remarkable 300% enhancement in device sensing performance and durability, surpassing the capabilities of pristine V-MXene. This advancement not only paves the way towards the creation multifunctional, cutting-edge personal health care devices, but also holds great promises for the progression of clean energy conversion and storage technologies.

Moreover, the utilization of the industrially scalable ALD technique used in this research enables precise engineering of MXene surfaces with precious metals, thereby opening up new possibilities for future applications.

"We are thrilled by the potential of this breakthrough," said Professor Kim. "The precision-enabled integration of precious metals opens up a whole new world of possibilities in the development of versatile, next-generation, and safe personal health care devices, as well as clean energy conversion and storage systems, with the potential to substantially impact people's lives."
