Using MXene as a Chemically Induced Initiator to Construct High‐Performance Cathodes for Aqueous Zinc‐Ion Batteries

Jie Chen, Yanpeng Liu, Baoquan Xiao, Juanjuan Huang, more

Angewandte Chemie > 136 > 35 > n/a - n/a

MXene usually exhibits weak pseudo‐capacitance behavior in aqueous zinc‐ion batteries, which cannot provide sufficient reversible capacity, resulting in the decline of overall capacity when used as the cathode materials. Taking inspiration from polymer electrolyte engineering, we have conceptualized an in situ induced growth strategy based on MXene materials. Herein, 5.25 % MXene was introduced into...

Kun Zhu, Nana Zhang, Changjun Jiang, Dandan Zhu

Software: Practice and Experience > 54 > 2 > 308 - 333

Software defect prediction (SDP) aims to build an effective prediction model for historical defect data from software repositories by some specialized techniques or algorithms, and predict the defect proneness of new software modules. Nevertheless, the complex internal intrinsic structure hidden behind the defect data makes it challenging for the built prediction model to capture the most expressive...

Demetallization of heavy oil through pyrolysis: A reaction kinetics analysis

Xue‐Feng Chen, Zhi‐Jian Da, Jian‐Hong Gong, Hua‐Jie Zhang, more

AIChE Journal > 67 > 1 > n/a - n/a

By tracking the transfer of vanadium and nickel in pyrolysis products, a seven‐lump reaction kinetic model for pyrolysis‐based demetallization of heavy oil was established. During pyrolysis, the demetallization of heavy oil is achieved by condensing metal‐rich resins and asphaltenes to coke. The condensation of oil components originally contained in heavy oil differs greatly in reaction behavior,...
