Summary: This study proposes and evaluates Co-doped MnO2 with abundant oxygen vacancies as the cathode material for aqueous magnesium ion hybrid supercapacitors (MHSs). The decrease in the combined valence of Mn caused by Co doping leads to more oxygen vacancies, which improves the electronic conductivity and promotes the adsorption/desorption behavior of Mg2+. Additionally, Co intercalation enhances the stability of the electrode material. An MHS based on the Co-MnO2 cathode exhibits excellent energy density and long-term cycling life.

Summary: A novel Ti3C2Tx MXene was introduced to fabricate a MoS2/Ti3C2Tx hybrid through a facile hydrothermal approach, greatly improving the reaction kinetics of the hybrid electrode. By increasing the discharge cut-off voltage to 0.2 V, the MoS2/Ti3C2Tx showed remarkable sodium storage performance in terms of specific capacity, cyclability, and rate capability, with negligible capacity decay after 1000 cycles at 1.0 A g(-1). The improved electrochemical performance originates from effective avoidance of deep conversion reactions below 0.2 V and enhanced electronic kinetics due to the combination with Ti3C2Tx flakes. The modifications of electrode structure and cut-off voltage provide an effective way to optimize the electrochemical redox of the target electrode.

Summary: Developing flexible electromagnetic interference (EMI SE) shielding materials is crucial for protecting humans from harmful radiation. We designed and fabricated a flexible multilayer structure of PVDF/GNP-PVDF composite film, which exhibited high EMI SE performance (averaging 69.7 dB in X-band), excellent flexibility, and stability (98.85% retention after bending 1000 cycles at 60 degrees). The theoretical study indicates that the multiple reflection and absorption of electromagnetic waves between layers contribute to the high EMI SE performance of the PVDF/GNP-PVDF multilayer film.

Summary: In this study, CoMnOx/g-C3N4 hybrid catalysts were developed by integrating CoMnOx bimetallic oxides onto a 3D porous g-C3N4 support via activated peroxymonosulfate (PMS). The catalyst achieved high degradation efficiency for antibiotics and pollutants, and the experimental and theoretical findings suggest a non-free radical catalytic mechanism that relies on 1O2 as the primary active species. This work provides a model for understanding the critical roles played by cooperative bimetallic nanoclusters in PMS activation for efficient antibiotic degradation, and presents new opportunities for designing and controlling chemical compounds for water treatment.
