Defect‐rich carbon materials possess high gravimetric potassium storage capability due to the abundance of active sites, but their cyclic stability is limited because of the low reversibility of undesirable defects and the deteriorative conductivity. Herein, in situ defect‐selectivity and order‐in‐disorder synergetic engineering in carbon via a self‐template strategy is reported to boost the K+‐storage capacity, rate capability and cyclic stability simultaneously. The defect‐sites are selectively tuned to realize abundant reversible carbon‐vacancies with the sacrifice of poorly reversible heteroatom‐defects through the persistent gas release during pyrolysis. Meanwhile, nanobubbles generated during the pyrolysis serve as self‐templates to induce the surface atom rearrangement, thus in situ embedding nanographitic networks in the defective domains without serious phase separation, which greatly enhances the intrinsic conductivity. The synergetic structure ensures high concentration of reversible carbon‐vacancies and fast charge‐transfer kinetics simultaneously, leading to high reversible capacity (425 mAh g−1 at 0.05 A g−1), high‐rate (237.4 mAh g−1 at 1 A g−1), and superior cyclic stability (90.4% capacity retention from cycle 10 to 400 at 0.1 A g−1). This work provides a rational and facile strategy to realize the tradeoff between defect‐sites and intrinsic conductivity, and gives deep insights into the mechanism of reversible potassium storage.

Potassium‐Ion Batteries Defect‐rich carbon materials possess high gravimetric potassium storage capability, but their cyclic stability is limited because of the low reversibility of undesirable defects and their deteriorative conductivity. In article number 2108621, Zhicheng Ju, Shenglin Xiong, and co‐workers propose an in situ defect‐selectivity and order‐in‐disorder synergetic engineering in carbon materials via a self‐template strategy to boost the K+‐storage capacity, rate capability, and cyclic stability simultaneously.

In article number 2006003, Yuan Ping and co‐workers, by means of photothermal transcription of CRISPR/Cas9 in the second near‐infrared window, demonstrate genome editing of PD‐L1 to be effective to reprogram the tumor microenvironment. The photothermal genome editing for the disruption of PD‐L1 mediated by supramolecular gold nanorods also simultaneously activates T cells to infiltrate and attack tumor cells in the deep tissues, which can substantially improve cancer immunotherapy.

In this study, highly effective organic–inorganic composites Fe/​C/​PPy (Fe/C nanocapsules embedded in polypyrrole) were prepared by combining the arc-discharge process and in situ oxidative polymerization method. It was found that Fe/C/​PPy-paraffin composites have higher dielectric loss in comparison with both Fe/C-paraffin and PPy-paraffin composites, implying enhanced dielectric properties by this embedded structure. The RL (reflection loss) exceeding −10 dB is obtained in the 11.2–16.9 GHz for a given thickness of 2.2 mm, which covers most of the Ku-band (12–18 GHz). The RL exceeding −10 dB is obtained in the 9.6–14.1 GHz for a given thickness of 2.5 mm, which covers most of the X-band (8–12 GHz). The illustration of the physical model indicated that the special embedded structure with abundant heterogeneous interfaces is responsible for the excellent microwave-absorption performances.
