Uncontrollable dendrite growth resulting from the non-uniform lithium ion(Li^(+))flux and volume expansion in lithium metal(Li)negative electrode leads to rapid performance degradation and serious safety problems of lithium metal *** N-containing functional groups in carbon materials are reported to be effective to homogenize the Li^(+)flux,the effective interaction distance between lithium ions and N-containing groups should be relatively small(down to nanometer scale)according to the Debye length ***,it is necessary to carefully design the microstructure of N-containing carbon materials to make the most of their roles in regulating the Li^(+)*** this work,porous carbon nitride microspheres(PCNMs)with abundant nanopores have been synthesized and utilized to fabricate a uniform lithiophilic coating layer having hybrid pores of both the nano-and micrometer scales on the Cu/Li ***,the three-dimensional(3D)porous framework is favorable for absorbing volume changes and guiding Li ***,this coating layer can render a suitable interaction distance to effectively homogenize the Li^(+)flux and contribute to establishing a robust and stable solid electrolyte interphase(sEI)layer with Li-F,Li-N,and Li-O-rich contents based on the Debye length *** a physical-chemical synergic regulation strategy using PCNMs can lead to dendrite-free Li plating,resulting in a low nucleation overpotential and stable Li plating/stripping cycling performance in both the Li||Cu and the Li||Li symmetric ***,a full cell using the PCNM coated Li foil negative electrode and a LiFePO4 positive electrode has delivered a high capacity retention of~80%after more than 200 cycles at 1 C and achieved a remarkable rate *** pouch cell fabricated by pairing the PCNM coated Li foil negative electrode with a NCM 811 positive electrode has retained~73%of the initial capacity after 150 cycles at 0.2 C.

柔性和半透明是有机太阳能电池(OsCs)的重要优势,受到科学界和工业界的广泛关注.目前,提高柔性半透明OsCs(st-OsCs)性能的关键是柔性透明电极(FtEs)和吸光活性层.本文制备了透过率为84.8%的复合FtEs,这使得活性层可以高效捕获太阳光,优化了器件中的光管理.此外,在活性层中采用了多种成熟的策略,包括构筑类合金近红外受体(Y6:m-BtP-PhC6)和稀释可见光范围强吸收的给体(PM6),使得每个光子被精确利用,有效平衡了st-OsCs效率和透过率之间的冲突.利用以上策略,提高了活性层中可见光的透过和近红外光的吸收,最终获得了高透明度的活性层,其平均可见光透过率(AVt)值为39.3%.基于此,柔性不透明和半透明OsCs分别获得了16.44%和11.48%的能量转换效率,这是目前柔性st-OsCs的最高效率之一.本工作对实现具有优异鲁棒性和高性能的st-OsCs具有重要的指导意义,也为其实际应用迈出了重要一步.

A viral protein orchestrates rice ethylene signaling to coordinate viral infection and insect vector-mediated transmission

Arthropod-borne viruses cause serious threats to human health and global agriculture by rapidly spreading via insect vectors. southern rice black-streaked dwarf virus (sRBsDV) is the most damaging rice-infecting virus that is frequently transmitted by planthoppers. However, the molecular mechanisms underlying its propagation in the host plants and epidemics in the field are largely unknown. Here, we showed that the sRBsDV-encoded P6 protein is a key effector that regulates rice ethylene signaling to coordinate viral infection and transmission. In early sRBsDV infection, P6 interacts with OsRtH2 in the cytoplasm to activate ethylene signaling and enhance sRBsDV proliferation;this also repels the insect vector to reduce infestation. In late infection, P6 enters the nucleus, where it interacts with OsEIL2, a key transcription factor of ethylene signaling. the P6-OsEIL2 interaction suppresses ethylene signaling by preventing the dimerization of OsEIL2, thereby facilitating viral transmission by attracting the insect vector. Collectively, these findings reveal a novel molecular mechanism by which an arbovirus modulates the host defense system to promote viral infection and transmission.

Carbon dots(CDs), as a new member of carbon nanostructures, have been widely applied in extensive fields due to their exceptional physicochemical properties. While, the emissions of most reported CDs are located in the blue to green range under the excitation of ultraviolet or blue light, which severely limits their practical applications, especially in photovoltaic and biological fields. studies that focused on synthesizing CDs with long-wavelength(red to near-infrared) emission/excitation features(simply named L-w CDs) and exploring their potential applications have been frequently reported in recent years. In this review, we analyzed the key influence factors for the synthesis of CDs with long wavelength and multicolor(containing long wavelength) emissive properties, discussed possible fluorescence mechanism,and summarized their applications in sensing and cancer theranostics. Finally, the existing challenges and potential opportunities of L-w CDs are presented.
