1 Introduction The blast furnace tap hole is subjected to extreme service conditions, including exposure to molten iron above 1400°C, repeated mechanical drilling, and stringent requirements for rapid opening, stable tapping, and reliable sealing [-]. Tap hole clay, as the critical refractory material employed in this region, directly dictates the stability, operational safety, and economic efficiency of blast furnace processes [9].

Regulation of Heterogeneous Electron Transfer Reactivity by Defect Engineering through Electrochemically Induced Brominating Addition Enhancing the electrochemical activity of graphene holds great significance for expanding its applications in various electrochemistry fields. In this study, we have demonstrated a facile and quantitative approach for modulating the defect density of single-layer graphene (SLG) via an electrochemically induced bromination process facilitated by cyclic voltammetry.

Electrochemical Regulation of the Band Gap of Single Layer Gra-phene: From Semimetal to Semiconductor Lanping Zeng, Weiying Song, Xiangfeng Jin, Quanfeng He, Lianhuan Han, Yuanfei Wu, Corinne Lagrost, Yann Leroux, Phillipe Hapiot, Yang Cao, Jun Cheng and Dongping Zhan Abstract As a semimetal with zero band gap and single-atom-scale thickness, single layer graphene (SLG) has an excellent electron conductivity on its basal plane.
