The construction of advanced Zn‐ion hybrid supercapacitors (ZHSCs) with high energy density is promising but still challenging, especially at high current densities. In this work, a high‐energy and ultrastable aqueous ZHSC is demonstrated by introducing N dopants into a hierarchically porous carbon cathode for the purpose of enhancing its chemical adsorption of Zn ions. Experimental results and theoretical simulations reveal that N doping not only significantly facilitates the chemical adsorption process of Zn ions, but also greatly increases its conductivity, surface wettability, and active sites. Consequently, the as‐fabricated aqueous ZHSC based on this N‐doped porous carbon cathode displays an exceptionally high energy density of 107.3 Wh kg−1 at a high current density of 4.2 A g−1, a superb power density of 24.9 kW kg−1, and an ultralong‐term lifespan (99.7% retention after 20 000 cycles), substantially superior to state‐of‐the‐art ZHSCs. Particularly, such a cathode also leads to a quasi‐solid‐state device with satisfactory energy storage performance, delivering a remarkable energy density of 91.8 Wh kg−1. The boosted energy storage strategy by tuning the chemical adsorption capability is also applicable to other carbon materials.

BackgroundPyroptosis is a new programmed cell death discovered in recent years. Pyroptosis plays an important role in various diseases. Nevertheless, there are few bibliometric analysis systematically studies this field. We aimed to visualize the research hotspots and trends of pyroptosis using a bibliometric analysis to help understand the future development of basic and clinical research.MethodsThe articles and reviews regarding pyroptosis were culled from Web of Science Core Collection. Countries, institutions, authors, references and keywords in this field were visually analyzed by using CtieSpace and VOSviewer software.ResultsA total of 2845 articles and reviews were included. The number of articles regarding pyroptosis significantly increased yearly. These publications mainly come from 70 countries led by China and the USA and 418 institutions. We identified 605 authors, among which Thirumaladevi Kanneganti had the most significant number of articles, and Shi JJ was co-cited most often. Frontiers in immunology was the journal with the most studies, and Nature was the most commonly cited journal. After analysis, the most common keywords are nod like receptor family pyrin domain containing 3 inflammasome, apoptosis, cell death, gasdermin D, mechanism, caspase-1, and others are current and developing areas of study.ConclusionResearch on the pyroptosis is flourishing. Cooperation and exchanges between countries and institutions must be strengthened in the future. The related pathway mechanism of pyroptosis, the relationship between pyroptosis and other types of programmed cell deaths as well as the role of pyroptosis in various diseases have been the focus of current research and developmental trends in the future research.

Zinc-ion hybrid supercapacitors (ZHSCs) have garnered increasing attention as promising energy storage devices in recent years, as they combine the advantages of high-energy Zn-ion batteries and high-power supercapacitors. However, the development of ZHSCs is still in its infancy and there are many bottlenecks to overcome. In particular, the challenge induced by the limited ion adsorption capability of carbon-positive electrodes severely restricts the energy density of ZHSCs. Therefore, it has become a key issue to design novel carbon-positive electrodes that enable high energy density yet do not deteriorate the intrinsic power capability and long-term durability. This study focuses on recent achievements in synthesis, morphology, and electrochemical performance of various carbon materials applied in ZHSCs. The modification strategies to optimize their electrochemical performance are briefly summarized. In addition, current challenges and future opportunities in this field are also outlined. This review will be beneficial to provide an organized framework for the research systems of carbon-positive electrodes and develop novel ZHSCs with high energy density.

Among various charge-carrier ions for aqueous batteries, non-metal hydronium (H 3 O +) with small ionic size and fast diffusion kinetics empowers H 3 O +-intercalation electrodes with high rate performance and fast-charging capability. However, pure H 3 O + charge carriers for inorganic electrode materials have only been observed in corrosive acidic electrolytes, rather than in mild neutral electrolytes. Herein, we report how selective H 3 O + intercalation in a neutral ZnCl 2 electrolyte can be achieved for water-proton co-intercalated a-MoO 3 (denoted WP-MoO 3). H 2 O molecules located between MoO 3 interlayers block Zn 2+ intercalation pathways while allowing smooth H 3 O + intercalation/diffusion through a Grotthuss proton-conduction mechanism. Compared to a-MoO 3 with a Zn 2+-intercalation mechanism, WP-MoO 3 delivers the substantially enhanced specific capacity (356.8 vs. 184.0 mA h g À1), rate capability (77.5 % vs. 42.2 % from 0.4 to 4.8 A g À1), and cycling stability (83 % vs. 13 % over 1000 cycles). This work demonstrates the possibility of modulating electrochemical intercalating ions by interlayer engineering, to construct high-rate and long-life electrodes for aqueous batteries.
