The development and utilization of renewable clean energy can effectively solve the two major problems of energy and environment. As an efficient power generation device that converts hydrogen energy into electric energy, fuel cell has attracted more and more attention. For fuel cells, the oxygen reduction reaction(ORR) at the cathode is the core reaction, and the design and development of high-performance ORR catalysts remain quite challenging. Since the microenvironment of the active center of single atom catalysts(SACs) has an important influence on its catalytic performance, it has been a research focus to improve the ORR activity and stability of electrocatalysts by adjusting the structure of the active center through reasonable structural regulation methods. In this review, we reviewed the preparation and structure–activity relationship of SACs for ORR. Then, the structural precision regulation methods for improving the activity and stability of ORR electrocatalysts are discussed. And the advanced in-situ characterization techniques for revealing the changes of active sites in the electrocatalytic ORR process are summarized. Finally, the challenges and future design directions of SACs for ORR are discussed. This work will provide important reference value for the design and synthesis of SACs with high activity and stability for ORR.

Electrocatalytic CO_(2)reduction reaction(CO_(2)RR)is considered an efficient way to convert CO_(2)into high-value-added chemicals,and thus is of significant social and economic value.Metal single-atomic site catalysts(SASCs)generally have excellent selectivity because of their 100%atomic utilization and uniform structure of active sites,and thus promise a broad range of applications.However,SASCs still face challenges such as low intrinsic activity and low density of active sites.Precise regulation of the microstructures of SASCs is an effective method to improve their CO_(2)RR performance and to obtain deep reduction products.In this article,we systematically summarize the current research status of SASCs developed for highly efficient catalysis of CO_(2)RR,discuss the various structural regulation methods for enhanced activity and selectivity of SASCs for CO_(2)RR,and review the application of in-situ characterization technologies in the SASC-catalyzed CO_(2)RR.We then discuss the problems yet to be solved in this area,and propose the future directions of the research on the design and application of SASCs for CO_(2)RR.

The development of bifunctional electrocatalysts with high activity and stability for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)is crucial for efficient overall water splitting but still challenging.Herein,we propose a facile and effective polymerization–pyrolysis–selenization(PPS)strategy for in-situ synthesis of N-doped carbon nanosnakes(NCNSs)encapsulated Fe-doped CoSe nanoparticles(NPs)derived from predesigned trimetallic Zn/Fe/Co polyphthalocyanine conjugated polymer networks.Benefiting from the synergistic effect between the regulation of Fe atoms and CoSe NPs as well as the confinement effect of in situ formed porous conductive carbon nanosnakes,the FeCoSe@NCNSs catalyst exhibited the excellent electrocatalytic activity for HER with small overpotentials(142 and 99 mV in 0.5 M H_(2)SO_(4) and 1 M KOH)and OER(320 mV in 1 M KOH)at the current density of 10 mA cm^(-2).Particularly,it also can be used as an efficient bifunctional electrocatalyst with a cell voltage of 1.66 V to achieve a current density of 10 mA cm^(-2) and superior stability for overall water splitting.Density functional theory study reveals that the doping of Fe atoms on Co Se enhanced the splitting and delocalization of metal-d orbitals close Fermi level,and modifies the distribution of Se-p orbitals close Fermi level,which improved the flexibility of electron donor-acceptor system and the hydrogen adsorption free energy change on metal-metal bridge sites in FeCoSe@NCNSs.Additionally,beneficial from the accepting of Fe-Se bridge site,the overpotential of OER which following intramolecular oxygen coupling mechanism is also decreased,thus accelerating the electrocatalytic performance.This work presents a novel strategy to regulate the activity and stability of transition metal selenides and facilitating the rational design of bifunctional electrocatalysts for overall water splitting applications.

Plant receptor-like protein kinases(RLKs) are transmembrane proteins with an extracellular domain and an intracellular kinase domain, which enable plant perceiving diverse extracellular stimuli to trigger the intracellular signal transduction. The somatic embryogenesis receptor kinases(SERKs) code the leucine-rich-repeat receptor-like kinase(LRR-RLK), and have been demonstrated to associate with multiple ligand-binding receptors to regulate plant growth, root development, male fertility, stomatal development and movement, and immune responses. Here, we focus on the progress made in recent years in understanding the versatile functions of Arabidopsis SERK proteins, and review SERK proteins as co-receptor to perceive different endogenous and environmental cues in different signaling pathway, and discuss how the kinase activity of SERKs is regulated by various modification.

Brain-to-brain interfaces(BtBIs) hold exciting potentials for direct communication between individual brains. However,technical challenges often limit their performance in rapid information transfer. Here, we demonstrate an optical brain-to-brain interface that transmits information regarding locomotor speed from one mouse to another and allows precise, real-time control of locomotion across animals with high information transfer rate. We found that the activity of the genetically identified neuromedin B(NMB) neurons within the nucleus incertus(NI) precisely predicts and critically controls locomotor speed. By optically recording Ca2+ signals from the NI of a "Master" mouse and converting them to patterned optogenetic stimulations of the NI of an "Avatar" mouse, the Bt BI directed the Avatar mice to closely mimic the locomotion of their Masters with information transfer rate about two orders of magnitude higher than previous Bt BIs. These results thus provide proof-of-concept that optical Bt BIs can rapidly transmit neural information and control dynamic behaviors across individuals.

西北太平洋夏季风指数与同时期夏季的Nino3.4指数的相关系数在90年代初期以后出现显著的增强。两者相关系数的这种年代际变化可能跟中太平洋型ENSO的更频繁发生以及ENSO相关联的其他热带洋盆的海表面温度异常有关。在90年代之后(之前),显著的热带大西洋(印度洋)海表面温度异常倾向伴随夏季Nino3.4海表面温度异常同时出现,并且能够增强(减弱)Nino3.4海表面温度异常所引起的西北太平洋夏季风异常,从而能够增强(减弱)Nino3.4海表面温度与西北太平洋夏季风指数之间的相关系数。另一方面,由春季北大西洋海表面温度异常所引起的前一年冬季El Nino更快的衰减速率,也能够促进夏季Nino3.4指数与西北太平洋夏季风之间村相关系数在90年代之后的增加。这些结果表明来自大西洋海温影响的增强可能导致了夏季Nino3.4指数与西北太平洋夏季风指数之间的相关系数在90年代之后的显著增加。

Non-spherical particles exist widely in natural and industrial fluid systems and the motions of nonspherical particles are significantly different from that of spherical particles.In this paper,a simplified model of non-spherical particles considering particle drag correction,lift,and rotation was established.Based on the Eulerian-Lagrangian simulation,the dispersion characteristics of spherical and nonspherical particles with different Stokes numbers in a high-speed turbulent jet were analyzed and compared considering the effect of particle rotation.The results show that,the differences in particle dispersion and radial velocity fluctuation between non-spherical particles and spherical particles in the jet are significant,especially when Stokes number is large.Moreover,the effects of different type of forces on the dispersion of non-spherical particles and spherical particles were compared in detail,which revealed that the change of the Magnus force caused by the increase in the angular velocity of non-spherical particles plays a dominant role in the differences of particle dispersion.

A nanoplasmonic hydrogen-sensing system based on palladium/silver nanosheets （Pd/Ag NSs） was developed and used for sensitive assessment of the hydrogen evolution reaction （HER） in colloid solutions. As a model HER system, the semiconductor CdS/CdSe core/shell quantum dot （QD）-based hydrogen-producing colloidal system was used, and the HER performances of QDs with two different surface coatings were assessed in this study. In the sensing system, the photocatalytically generated hydrogen reacts with Pd/Ag NSs, resulting in a gradual red-shift of localized surface plasmon resonance, which to a certain degree is almost linearly proportional to the amount of hydrogen generated. Such a nanoplasmonic hydrogen sensing platform would be useful as an alternative for optical assessment and fast selection of a highly efficient and cost-effective solar hydrogen generation system for practical applications.

The intensity of the interannual variability(IIV)of the mean tropical cyclone(TC)genesis latitude over the western North Pacific(WNP)has been weakening significantly since the late 1990 s.It is found that the IIV of the mean TC genesis latitude depends largely on the strength of the out-of-phase relationship between TC genesis numbers in the north(north of 15°N)and south(south of 15°N)of the WNP.A weaker(stronger)north–south TC see-saw has led to a smaller(larger)IIV of the mean TC genesis latitude after(before)the late 1990 s.Different configurations of sea surface temperature(SST)anomalies are found to be responsible for the decadal changes in the north–south TC see-saw and dipole structure.Before the late 1990 s,the joint effect of SST anomalies over the tropical Pacific and tropical North Indian Ocean dominated,rendering the obvious north–south TC see-saw and larger IIV of the mean TC genesis latitude.After the late 1990 s,however,the dominant SST anomalies associated with TC genesis shift to the tropical central Pacific(CP)and tropical North Atlantic Ocean,which have weakened the north–south TC seesaw and reduced the IIV of the mean TC genesis latitude.These observed decadal changes in the configuration of SST anomalies are considered to be closely associated with the shift of the El Ni?o–Southern Oscillation(ENSO)from eastern Pacific(EP)type to the CP type during the recent decades.The results suggest that the increased influences from the tropical Atlantic Ocean have become more important to the variations of TC activity in the WNP during the recent decades.These results may have important implications for assessing the latitudinal distributions of TC-induced hazards.
