Carbon doping has proven to be a highly effective strategy for enhancing the electrical properties of MgB2 wires, especially under a high magnetic field. However, unreacted doping material can persist as impurities due to uneven mixing or incomplete reactions, thereby detrimentally affecting electrical properties and their uniformity. In this study, we explore the application of pyrene doping to 18-multifilamentary MgB2 wires with a total length of 2.5 kilometers. The aim of this study is to min...

Abstract Evaluation and control of amorphous phases in materials are very important for optimizing their properties. Herein, we focus on polycrystalline MgB materials prepared with hydrocarbon doping and study the effects of residual amorphous impurities on the superconducting performance. Carbon is known to be an effective element for enhancing the transport critical current under an external magnetic field. The doped samples were prepared under two different nominal conditions, MgB (C H ) a...

Abstract It is demonstrated experimentally and confirmed theoretically that highly defective boron nitride showed outstanding performance for oxidative dehydrogenation of ethylbenzene. The catalyst is derived from carbon-doped hexagonal boron nitride nanosheets synthesized via a two-step reaction when participating the oxidative dehydrogenation reaction. The first step yields a polymeric precursor with the atomic positions of B, C, N relatively constrained, which is conducive for the formation ...
