受俄克拉荷马大学数学俱乐部主席邀请，冯元宁带着两位本科生：杰克逊·兰卡斯特和于蕙茹做了题为“打最小的结，编最薄的布”的报告。杰克逊和蕙茹通过亲身示范向观众介绍了拓扑学在数学中的起源及其在化学和纳米技术中的应用，即分子纳米拓扑学。元宁谈到了如何设计和合成分子结和交织网络，以及它们的未来发展方向。

Invited by the chair of the OU Math Club at the University of Oklahoma, Yuanning Feng brought two undergraduate students, Jackson Lancaster and Huiru Yu to give a talk entitled Tying the Tiniest Knot and Weaving the Thinnest Fabric. Jackson and Huiru introduced to the audience by using in person demonstration about the original of topology in mathematics and its application in chemistry and nanotechnology, which is coined as molecular nanotopology. Yuanning talked about how to design and synthesize molecular knots and interweaving networks, as well as their future aspect.
