Flexible aqueous zinc batteries(FAZBs)with high safety and environmental friendliness are promising smart power sources for smart wearable electronics.However,the bare zinc anode usually suffers from damnable dendrite growth and rampant side reaction on the surface,greatly impeding practical applications in FAZBs.Herein,a composite polymer interface layer is artificially self‐assembled on the surface of the zinc anode by graft‐modified fluorinated monomer(polyacrylic acid‐2‐(Trifluoromethyl)propenoic acid,PAA‐TFPA),on which an organic–inorganic hybrid(PAA‐Zn/ZnF2)solid electrolyte interface(SEI)with excellent ionic conductivity is formed by interacting with Zn2+.Both the pouch cell and fiber zinc anode exhibit excellent plating/stripping reversibility after protecting by this organic–inorganic SEI,which can be stably cycled more than 3000 h in symmetric Zn||Zn cells or 550 h in fiber Zn||Zn cells.Additionally,this interface layer preserves zinc anode with excellent mechanical durability under various mechanical deformation(stably working for another 1200 h after bending 100 h).The corresponding PAA‐Zn/ZnF2@Zn||MnO2 full cell displays an ultra‐long life span(79%capacity retention after 3000 cycles)and mechanical robustness(85%of the initial capacity for another 3000 cycles after bending 100 times).More importantly,the as‐assembled cells can easily power smart wearable devices to monitor the user's health condition.

Aqueous rechargeable ammonium-ion batteries(AIBs)have drew considerable attention because of their capacity for high rates,low cost,and high safety.However,developing desired electrodes requiring stable structure in the aqueous fast ammoniation/de-ammoniation becomes urgent.Herein,an ammonium ion full battery using Cu_(3)[Fe(CN)_(6)]_(2)(CuHCF)acting to be a cathode and barium vanadate(BVO)acting to be an anode is described.Its excellent electrochemical behavior of Prussian blue analogs and the perfectly matched lattice structure of NH_(4)^(+)is expected.And the open structure of vanadium compounds satisfies the fast ammoniation/de-ammoniation of NH4+is also achieved.As a result of these synergistic effects,the BVO//CuHCF full cell retains 80.5 percent of its capacity following 1000 cycling.These achievements provide new ideas for developing low-cost and long-life AIBs.

Dear Editor,Genetic variant Delta(B.1.617.2)of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which possesses a remarkable ability to transmit and spread,is currently becoming predominant worldwide.Despite its great harm to human beings,how the Delta variant with T478K,P681R and L452R mutations achieves its ultrafast spread remains elusive.Entry of SARS-CoV-2 into host cells is mediated by a rapid enzymatic hydrolysis.

Dear Editor,Alveolar macrophages(AMs)are among the first immune cells to encounter SARS-CoV-2 during an infection due to their abundant numbers and physical location in the lungs.Thus,the reaction of AMs to SARS-CoV-2 has a profound impact on the outcome of the infection.In most cases,AMs can release cytokines and prime adaptive T-and B-cell immune responses to resolve the infection.

Exploring the cross-talk between the immune system and advanced biomaterials to treat SARS-CoV-2 infection is a promising strategy.Here,we show that ACE2-overexpressing A549 cell-derived microparticles(AO-MPs)are a potential therapeutic agent against SARS-CoV-2 infection.Intranasally administered AO-MPs dexterously navigate the anatomical and biological features of the lungs to enter the alveoli and are taken up by alveolar macrophages(AMs).Then,AO-MPs increase the endosomal pH but decrease the lysosomal pH in AMs,thus escorting bound SARS-CoV-2 from phago-endosomes to lysosomes for degradation.This pH regulation is attributable to oxidized cholesterol,which is enriched in AO-MPs and translocated to endosomal membranes,thus interfering with proton pumps and impairing endosomal acidification.In addition to promoting viral degradation,AO-MPs also inhibit the proinflammatory phenotype of AMs,leading to increased treatment efficacy in a SARS-CoV-2-infected mouse model without side effects.These findings highlight the potential use of AO-MPs to treat SARS-CoV-2-infected patients and showcase the feasibility of MP therapies for combatting emerging respiratory viruses in the future.

With the merits of low cost,environmental benignity,and high safety,aqueous zinc ion batteries(AZIBs)have great potential in the field of energy storage.In this paper,we craft a Co-doped Ni3 S2 with abundant sulfur vacancies as effective cathode materials(Co-Ni_(3) S_(2-x)) for AZIBs by hydrothermal and chemical reduction method.Notably,cobalt doping and abundant sulfur vacancies can effectively increase the conductivity and the number of active sites for electrochemical reactions,which gives the Co-Ni_(3) S_(2-x) electrode the outstanding capability to energy storage.By coupling Co-Ni_(3) S_(2-x) cathode with Zn anodes to assemble alkaline AZIBs,the Co-Ni_(3) S_(2-x)//Zn full battery exhibits excellent specific capacity(183.9 mAh g^(-1) at 1 A g^(-1),based on cathode mass) and extraordinary cycling durability(72.9% capacity retention after 6000 cycles).First-principles calculations based on density functional theory(DFT) confirm that the Co-Ni_(3) S_(2-x) electrode has strong energy storage capacity and electrochemical stability.The results provide an extremely significant reference in designs of self-supported bimetallic sulfide nanosheets,which have promising applications in high-performance energy storage devices.
