MXenes are a new class of two dimensional material. These materials promise a greater choice in production of high quality 2D films, compared with graphene, h-BN, and MoS2. MXenes also exhibit low friction and adhesion when applied onto the surfaces of materials that slide against each other. However, a limited number of MXenes have been produced and very few studies of friction and wear of surfaces lubricated by MXenes. The Gachot group at the Vienna University of Technology has been a leader in developing these materials for lubrication and wear protection of surfaces. This proposed international collaboration will allow the Egberts group at the University of Calgary to conduct fundamental AFM studies to measure the friction, topography, and mechanical properties of these materials at the atomic and molecular length scale. This information will be used to support a greater mechanistic and physical understanding of the operation of these materials in engineering-scale tribotesting experiments, conducted at the Vienna University of Technology. This funding will also be used to support one MSc student for one year and provide an international experience for this student and a postdoctoral fellow to visit the Vienna University of Technology. Further, the data gathered as part of this funding opportunity will be used for the development of further collaborative grants in Canada and Austria, including the Alliance International and Austrian Science Fund grants.

MXENES是一类新的二维材料。与石墨烯，H-BN和MOS2相比，这些材料在高质量2D膜的生产中有更大的选择。当将MXENES应用于相互滑动的材料表面上时，MXENES也表现出低摩擦和粘附。但是，已经产生了数量有限的MXENE，很少有关于MXENES润滑表面的摩擦和磨损的研究。 维也纳技术大学的Gachot小组一直是开发这些材料以润滑和磨损表面保护的领导者。这项拟议的国际合作将使卡尔加里大学的Egberts小组能够进行基本的AFM研究，以测量原子和分子长度尺度上这些材料的摩擦，地形和机械性能。该信息将用于支持对这些材料在维也纳技术大学进行的工程规模的摩托车实验中对这些材料的运行的更深入的理解。这笔资金还将用于支持一名MSC学生一年，并为该学生和一名博士后研究员提供国际经验，以参观维也纳技术大学。此外，收集的数据作为此资助机会的一部分将用于开发加拿大和奥地利的进一步协作赠款，包括联盟国际和奥地利科学基金会的赠款。
