6月19日上午，由北京大学集成电路学院、集成电路学院高精尖创新中心、北京大学国家集成电路产教融合创新平台、集成电路科学与未来技术北京实验室、后摩尔时代微纳电子学科创新引智基地及北京大学校友会半导体分会联合主办的“未名·芯”论坛系列讲座第六十一期在微纳电子大厦103报告厅远程举办。本期邀请Pohang University of Science and Technology（POSTECH）的Prof. Hyung Gyu Park带来题为“Selective Permeation in Low-Dimensional Space”的精彩讲座。讲座由北京大学集成电路学院王路达研究员主持。
Park教授聚焦于纳米尺度上的物质输运，系统介绍了当前纳流体领域的研究现状。一维和二维材料的出现与发展，为构筑不同维度和尺寸的纳流体通道提供了材料支撑，在该尺度下的物质输运表现出与宏观连续流体截然不同的特性，为实现分子筛分、纳滤、分离传感等应用提供了广阔的前景。
在讲座中，Park教授详细介绍了自己在纳流体领域多年的研究成果。对于理想薄膜，物质在通道中运输时的能量耗散应尽可能小。Park教授在实验上证实了一维碳纳米管通道中，水分子输运相比于经典哈根-泊肃叶流得到显著增强的现象，并揭示了增强因子对孔径和通道长度的依赖性，验证了在该体系中水分子低能量损耗的无摩擦高速流动。此外，Park教授的研究也聚焦于超薄二维材料，通过在二维材料面内引入零维的纳米孔限域空间，降低通道长度，能够实现兼具高通量和高选择性的筛分。
讲座结束后，同学们热情高涨，分享了自己对Park教授的研究成果的思考，Park教授就纳米孔石墨烯在分离时的稳定性、应用前景等问题与现场师生进行了深入交流探讨，就低维材料及纳流体领域的发展前景发表了自己的见解，为在场师生带来了鼓励和深刻启发。
个人简介：
Prof. Hyung Gyu Park is a Full Professor in the Department of Mechanical Engineering at Pohang University of Science and Technology (POSTECH), Korea, where he has been leading the Laboratory of Nanoscience for Energy Technology and sustainability since 2019 and conducting the Center for Low-Dimensional Transport Physics funded by the National Research Foundation of Korea since 2020. He received his Ph.D. in Mechanical Engineering (2007) from the University of California, Berkeley, CA, USA, with the development and analysis of a reformer system for a microscale hydrogen fuel cell and pioneering research on nanoscale mass transport in carbon nanotubes. After a postdoctoral training at Lawrence Livermore National Laboratory, CA, USA, he joined the Department of Mechanical and Process Engineering at the Swiss Federal Institute of Technology (ETH) Zurich, Switzerland, in 2009 and received tenure in 2015. His primary research interest lies in nanoscale transport physics and syntheses of nanocarbon- and 2D materials with which to explore nanomanufacturing options for multiscale integration, chem-bio sensing, energy harvesting and storage, carbon nanofluidics, and membrane technology for sustainable industrialization. He received from R&D Magazine, U.S.A., the 2010 R&D 100 Award and Editor's Choice Award in recognition of his contribution to “Ultrapermeable Carbon Nanotube Membranes.” in 2018, he was awarded a quest professorship at Seoul National University (School of Mechanical and Aerospace Engineering) supported by the "Brain Pool" program of the National Research Foundation of Korea.
