| 2 | Highly N-doped carbon with low graphitic-N content as anode material for enhanced initial Coulombic efficiency of lithium-ion batteries显示文摘N-doped carbons as one of the most prominent anode materials to replace standard graphite exhibit outstanding Li+storage performance.However,N-doped carbon anodes still suffer from low N-doping levels and low initial Coulombic efficiency(ICE).In this study,high N-doped and low graphitic-N carbons(LGNCs)with enhanced ICE were synthesized by taking advantage of a denitrification strategy for graphitic carbon nitride(g-C_(3)N_(4)).In brief,more than 14.5 at%of N from g-C_(3)N_(4)(55.1 at%N)was retained by reacting graphitic-N with lithium,which was subsequently removed.As graphitic-N is largely responsible for the irreversible capacity,the anode's performance was significantly increased.Compared to general N-doped carbons with high graphitic-N proportion(>50%)and low N content(<15 at%),LGNCs delivered a low proportion of 10.8%-17.2% within the high N-doping content of 14.5-42.7 at%,leading to an enhanced specific capacity of 1499.9mAh g^(-1) at an ICE of 93.7% for the optimal sample of LGNC(4:1).This study provides a facile strategy to control the N content and speciation,achieving both high Li+storage capacity and high ICE,and thus promoting research and application of N-doped carbon materials. | Yihua Tang Jingjing Chen Zhiyong Mao Christina Roth Dajian Wang | 2023 | Carbon Energy2023，5，2： | 1 |
| 3 | K_(2P)18.1 translates T cell receptor signals into thymic regulatory T cell development显示文摘It remains largely unclear how thymocytes translate relative differences in T cell receptor(TCR)signal strength into distinct developmental programs that drive the cell fate decisions towards conventional(Tconv)or regulatory T cells(Treg).Following TCR activation,intracellular calcium(Ca^(2+))is the most important second messenger,for which the potassium channel K_(2P)18.1 is a relevant regulator.Here,we identify K_(2P)18.1 as a central translator of the TCR signal into the thymus-derived Treg(tTreg)selection process.TCR signal was coupled to NF-κB-mediated K_(2P)18.1 upregulation in tTreg progenitors.K_(2P)18.1 provided the driving force for sustained Ca^(2+) influx that facilitated NF-κB-and NFAT-dependent expression of FoxP3,the master transcription factor for Treg development and function.Loss of K_(2P)18.1 ion-current function induced a mild lymphoproliferative phenotype in mice,with reduced Treg numbers that led to aggravated experimental autoimmune encephalomyelitis,while a gain-of-function mutation in K_(2P)18.1 resulted in increased Treg numbers in mice.Our findings in human thymus,recent thymic emigrants and multiple sclerosis patients with a dominant-negative missense K_(2P)18.1 variant that is associated with poor clinical outcomes indicate that K_(2P)18.1 also plays a role in human Treg development.Pharmacological modulation of K_(2P)18.1 specifically modulated Treg numbers in vitro and in vivo.Finally,we identified nitroxoline as a K_(2P)18.1 activator that led to rapid and reversible Treg increase in patients with urinary tract infections.Conclusively,our findings reveal how K_(2P)18.1 translates TCR signals into thymic T cell fate decisions and Treg development,and provide a basis for the therapeutic utilization of Treg in several human disorders. | Tobias Ruck Stefanie Bock Steffen Pfeuffer Christina B.Schroeter Derya Cengiz Paul Marciniak Maren Lindner Alexander Herrmann Marie Liebmann Stjepana Kovac Lukas Gola Leoni Rolfes Marc Pawlitzki Nils Opel Tim Hahn Udo Dannlowski Thomas Pap Felix Luessi Julian A.Schreiber Bernhard Wunsch Tanja Kuhlmann Guiscard Seebohm Bjorn Tackenberg Patricia Seja Frank Doring Erhard Wischmeyer Achmet Imam Chasan Johannes Roth Luisa Klotz Gerd Meyer zu Hörste Heinz Wiendl Tobias Marschall Stefan Floess Jochen Huehn Thomas Budde Tobias Bopp Stefan Bittner Sven G.Meuth | 2022 | Cell Research2022，32，1： | 1 |
| 4 | Detrimental role of hydrogen evolution and its temperature-dependent impact on the performance of vanadium redox flow batteries显示文摘This paper addresses the damaging role of the parasitic hydrogen evolution reaction (HER) in the negative half-cell of a vanadium redox flow battery (VRFB) on state-of-the-art carbon felt electrodes at different temperatures. It was found that increasing the temperature resulted in a better catalytic performance for both the positive and negative half-cell reactions. In addition, increasing the temperature significantly enhanced the undesired HER at the negative side. Operating the VRFB cell at higher temperature led to a decrease in the coulombic efficiency attributed to the higher hydrogen production. More pronounced hydrogen production caused an oxidation on the surface of the carb on fibers and a degradation of the electrode as indicated from scanning electron microscopy and X-ray photoelectron spectroscopy measurements. This observed degradation results in fading of the overall performance of the vanadium redox flow battery over time. | Abdulmonem Fetyan Gumaa A.

| 5 | Carbon‑Based Electrodes for Advanced Zinc‑Air Batteries:Oxygen‑Catalytic Site Regulation and Nanostructure Design显示文摘Zn-air batteries are highly attractive for direct chemical-to-electrical energy conversion and for solving the energy crisis and environmental problems.Designing efficient oxygen electrodes has been considered one of the most critical steps in the development of advanced Zn-air batteries because of the sluggish kinetics of the oxygen reduction reaction and the oxygen evolution reaction.In recent years,nanostructured carbon-based electrodes with large surface areas,efficient oxygen-catalytic centers,and hierarchically porous matrices have provided significant opportunities to optimize the performance of the oxygen electrodes in both primary and rechargeable Zn-air batteries.In this review,we provide a comprehensive summary of the reported nanostructured carbon-based electrodes for advanced Zn-air batteries in terms of tailoring the oxygen-catalytic sites and designing carbon supports.The versatile synthetic strategies,characterization methods,and in-depth understanding of the relationships between the oxygen-catalytic sites/nanostructures and the oxygen electrode performance are systematically summarized.Furthermore,we also briefly outline recent progress in engineering flexible and high-power Zn-air batteries.Ultimately,a thorough discussion of current primary challenges and future perspectives on the rational design of nanostructured carbon-based oxygen electrodes is given,thus providing inspiration for the future prosperity of fast-kinetic and efficient Zn-air batteries in a broad range of energy fields. | Wenjie Shao Rui Yan Mi Zhou Lang Ma Christina Roth Tian Ma Sujiao Cao Chong Cheng Bo Yin Shuang Li | 2023 | Electrochemical Energy Reviews2023，6，1： | 0 |
