Professor Park Nam-gyu from the School of Chemical Engineering at Sungkyunkwan University in South Korea delivered the latest installment of the Institute for Advanced Study (IAS) Distinguished Lecture Series at City University Hong Kong on 11 June. At the lecture, titled “Lead Halide Perovskite: Photovoltaics and Beyond”, Professor Park said a universal method and interfacial nano-engineering had been developed to eliminate hysteresis, which is the lag in response exhibited in a body when reacting to forces affecting it.

南韓成均館大學化學工程學院朴南圭教授於6月11日在香港城市大學主持最新一場高等研究院傑出講座系列，題為「鉛鹵鈣鈦礦：光伏及其他」。朴教授指其團隊研發了一個通用方法和界面納米工程，用作消除遲滯現象。遲滯現象是指物件受力後延後出現反應。他指表面鈍化劑和低維中間層顯著提升穩定性，同時大大減少遲滯情況。
